According to official data and reports by the Moroccan media, PAGER increased access to water in rural areas from 14% in 1995 to 61% in 2004 and 77% in 2006. Application of large volumes of saline produced water may adversely impact soil quality to some degree; however, this impact is less devastating than that from a large fire. 1, pp. International Association of Oil and Gas Producers, Guidelines for produced water injection, Report 2.80/302, 2002, http://www.ogp.org.uk/pubs/302.pdf. In 2009 the total volume of approved and on-going investment projects supported by KfW was Euro 407m, all executed by ONEP in small and medium-sized towns and rural areas. Our experts. The Colorado River has fallen to such historic lows that Lake Mead and Lake Powell the nation's two largest reservoirs could reach "dead pool", or the point at which water no longer passes downstream from a dam. In general, OGPW is considered an exempt waste and therefore can be injected in Class II or Class V injection wells. Flotation is most effective when gas bubble size is smaller than oil droplet size. These electrochemically driven processes separate dissolved ions from water through ion exchange membranes. This French creation with skis in front and tractor treads in back retails for 10,680 (around $11,402) and can hit speeds of 26 mph, with a battery that lasts three hours. Addition of significant organic amendments such as chicken or some feedlot manures can increase soil salinity over several applications. The project had been under preparation for seven years. Despite the high water recovery, MED has not been extensively used for water production like MSF because of scaling problems associated with early designs. 12, no. Activities such as well completions and truck washing may not require water to be of high quality. I would suggest a reputable water system business in your area to help ensure you have the right overall design for your needs. 8, pp. Adsorption processes are successfully applied to water treatment regardless of salinity. [16] Bulk water supply in the rest of the country was entrusted to a new national water company created in 1972, the Office National de l'Eau Potable (ONEP). At Custer Lake, Wyoming, approximately 30,000 barrels of water per day are discharged to what would normally be a seasonal playa lake. G. A. Burton Jr., N. Basu, B. R. Ellis, K. E. Kapo, S.

It looks really big. In order to prevent clay swelling around shale formations, clay stabilizers are injected with HF fluids. Morocco has about 22 billion cubic meters of conventional renewable water resources per year equivalent to 730 cubic meter/capita/year. 29742981, 2011. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.Water treatment removes contaminants and undesirable components, or We're here to help with any of your product inquiries. Produced water contains other trace metals including Al, B, Fe, Li, Mn, Se, and Sr. Certain metals are of particular environmental concern as they may bioaccumulate and/or be toxic [50]. Feed water is preheated and flows into a chamber with reduced air pressure where it immediately flashes into steam [234]. It is likely that these compounds, when in contact with soil, will enhance microbiological growth. While the Rabat concession was awarded directly to Vivendi in 1998, the concessions in Tangiers and Tetouan were awarded in 2002 after competitive bidding to Amendis, a subsidiary of Vivendi. The use of enzymes as breakers for fracturing fluids is preferred over the use of oxidizers because enzymes are environmentally benign [68]. Your e-mail will never sold or shared! 24, no. This story originally appeared in Los Angeles Times. The presence of various fatty acid phthalate esters in the Barnett and Marcellus produced water may be related to their use in HF fluids [102]. The University of Wollongong boasts world-leading experts across a range of disciplines. The major external partners in the sector are, in addition to the three named above, France, Germany and Japan. The residential tariff has four blocks, the lowest applying to consumption of less than 6 m per month and the highest to consumption above 40 m per month. The flushing solution is applied to the affected site via sprinklers or irrigation, or by subsurface injection. Required fields are marked *.

In 2006 it approved another loan of Euro 40m for sanitation in the Sebou basin, a highly polluted river where Fes and Meknes are located. Most individual spills were contained to the immediate drilling area, but many larger spills affected surrounding farms and waterways [36]. Wastewater resulting from OGPW treatment must be disposed in Class I injection wells. 105110, 2010. Phytoremediation is useful for soils contaminated with metals to shallow depths. The dual completion well costs about twice as much to install but took the same number of months to reach payout as the other wells. Ammonium chloride is also used [46, 72]. 47, no. Stripped hydrocarbons can be condensed and separated from feed water by gravity, and product water is either discharged or reused. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other Significant quantities of water are disposed in nonproducing formations above or below the oil- or gas-producing formation using injection tools within the well [100]. Toxnet, Mercaptoacetic acid, National Library of Medicine, Toxicology Data Network, 2015, http://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+2702. Human exposure to boron and amines used in cross-linkers is of concern as they have known toxic effects and can be mobile in soil and groundwater; however, the amines are not known to persist in the environment [46]. EPA defines Class I wells as technologically sophisticated wells that inject hazardous and nonhazardous wastes below the lowermost USDW. The Directorate of Public Utilities and Concessions (DRSC), also in the Ministry of the Interior, monitors the performance of Rgies and concessions. The US Environmental Protection Agency (US EPA) has attempted to regulate the use of diesel fuel in HF; however, it is still used in place of water as it can carry more guar concentrate per unit volume [43]. The investments in the water and sanitation sector increased substantially between 2003 and 2005. Ceramic UF/MF membranes have been used in a full-scale facility for treatment of produced water [189]. As salinity rises above a species-specific salinity threshold, crop yields decrease. Their level is low, not allowing the basin agencies to cover its own administrative costs, not to speak of contributing to the financing of investments by service providers as foreseen by the law. 1621, 2012.

After two years the rangeland was converted into highly productive grassland yielding livestock and wildlife benefits [100, 198]. Haying operations can continue while the field is being irrigated. 6134, 2013. An artificial sedge wetland system was constructed to treat produced water [14]. The major source of fouling of RO membranes was from organics in the feed water, including organic sulfur compounds. The method is most effective for produced water with Cl levels < 6600mg/L [189]. WebDuring oil and natural gas production, so-called “produced water” comprises the largest byproduct stream. R. W. Miller and P. Pesaran, Effects of drilling fluids on soils and plants: II. Cross-linkers bind gel molecules and thereby increase viscosity and proppant transport. It gets closer. 46 of Environmental Science Research, Springer, New York, NY, USA, 1992. Multistage flash (MSF) distillation, vapor compression distillation (VCD) and multieffect distillation (MED) are extensively used thermal desalination technologies [234]; however, hybrid thermal desalination plants, that is, MED-VCD, have achieved higher efficiencies [236]. [9] In 2009 a large reuse project was planned in Agadir to irrigate a golf course and municipal gardens with 50,000 cubic meters/day. The site is a marine wonderland, with a rich diversity of beautiful corals and thousands of aquatic creatures. (4) Electrodialysis/Electrodialysis Reversal. It can also be used in combination with conventional cleanup technologies (e.g., pump and treat of groundwater). A generalized chemical composition of produced water appears in Table 3.

Class II wells may be used to hold fluids associated with oil and natural gas production [52] and are classified either as disposal wells (IID) or as enhanced recovery wells (IIR). In 2005 a National Sanitation Program was approved that aims at treating 60% of collected wastewater and connecting 80% of urban households to sewers by 2020. Minimally treated produced water may be reused by petroleum operators for drilling operations. 162170, 2008. Erskine et al. The treated water is used for irrigation of fruit trees and other crops and for recharging shallow aquifers. Water recovery from MSF treatment is approx. "Substantial and immediate conservation now and in the coming months will help lessen the potential severity of such an allocation.". However, according to another source, in 2008 the connection fee for sewerage charged by ONEP was only 1,600 Dirham (about US$145). The objective is to extend water and sewer connections to 11.300 households in poor, unzoned, periurban neighbourhoods. Our systems are customizable to meet any need. BTEX, phenols, aliphatic hydrocarbons, carboxylic acid, and low molecular weight aromatics are classified as dissolved oil, while the more hydrophobic PAHs and heavy alkyl phenols are present in produced water as dispersed oil [100].

Vengosh, Iodide, bromide, and ammonium in hydraulic fracturing and oil and gas wastewaters: environmental implications, Environmental Science & Technology, vol. 8, pp. The primary completion is made at a depth corresponding to strong oil production, and a secondary completion is made lower in the strata at a depth experiencing significant water production. This produced water is a mixture of injected water, formation water, HF chemicals, and hydrocarbons [8285]. The same retail tariff structure applies to the entire country. Rainwater harvesting in the UK is both a traditional and reviving technique for collecting water for domestic uses and is generally used for non-hygienic purposes like watering gardens, flushing toilets, and washing clothes. Ethylene glycol is highly soluble in water; it adsorbs poorly to soil colloids and is thus highly mobile in the soil profile [114]. In certain geologic strata substantial volumes of oil and natural gas are present, yet they experience poor recovery rates due to low permeability of local strata. If your pump has to run longer to fill the tank each time it comes on then will this wear your pump out sooner? The most commonly studied metals are Ba, Cd, Cr, Cu, Pb, Hg, Ni, Ag, and Zn (Table 3) [50]. 108, no. [59], In 2006 the Islamic Development Bank provided two loans of Dirham 270 million (about Euro 27 million) for water supply. Morocco is divided in seven major river basins and a number of smaller basins. Nevertheless, an increase to Dirham 2.20 per m3 has been envisaged for 2009. Ponds are a favorable technology in regions where annual rainfall is relatively low and evaporation rates are high. T. I. R. Utvik, Composition, characteristics of produced water in the North Sea, in Proceedings of the Produced Water Workshop, Aberdeen, UK, March 2003.

OGPW components in soil may substantially impact each others fate and transport; for instance, the presence of biocides may decrease the potential for biodegradation, while viscosity-enhancing compounds may hinder the mobility of other compounds. 20%; it often requires posttreatment because it typically contains 210mg/L TDS [189]. We're dedicated to educating on clean water. The ED/EDR membrane lifetime is between 4 and 5 years. See how we can help you in your home or business, for life. OGPW management falls under two broad categories: underground injection and surface management. The volumetric tariff for each tariff block remained unchanged. 19, no. 111, no. 52, no. our company are focusing on environmental protection.Talking about the importance of not only the availability of clean water, but its consumption and attitude in our life. Protect your family and loved ones from water impurities with Water Tech Centralized Water Purifier and Water Filter Systems. 311326, 1966. Committee on Energy and Commerce. Morocco is increasingly looking towards seawater desalination as a source to supply its increasing water needs for drinking, industry and mining. We are committed to providing customers with the best quality service. 1, pp. 8, pp. [27] They also provide sewerage services in 280 towns (2003). All these factors cause adverse effects on plant growth and development at physiological and biochemical levels [152] and at the molecular level [153]. The total amount of its funding in the sector has been US$180 million until 2006, benefiting 20 Moroccan towns, in particular Tangiers. Dedicated to Clean Water EducationWater Defense is an online resource for Water Quality, Filtration & Softening guides. Gellants increase the viscosity of HF fluids. WebWhole House Water Filters and Softeners Our Whole House Water Filter systems address a variety of different water issues including Chlorine, VOC's, Fluoride, Arsenic, Nitrates, and much more. Approximately 100 bbl/day of produced water with salt concentrations > 60,000mg/L TDS can be processed [165]. The project relies on two basic principles: the use of simple technologies and the participation of beneficiaries in all stages of the project from the needs assessment to design, implementation and evaluation. Underground injection of OGPW often requires transport, along with treatment to reduce fouling and bacterial growth. "Conditions on the Colorado River are growing increasingly dire," MWD Chairwoman Gloria Gray said in a statement. Portable Desalination Filters, Hand Pumps, & Kits Small and/or portable desalination filters, hand pumps, kits and similar products are also available for personal/individual use Potential Pros & Cons Of Water Desalination Read more about the potential pros and cons of desalination in this guide. WebWater treatment is any process that improves the quality of water to make it appropriate for a specific end-use. Sulfur may be applied, either as elemental S or as aluminum sulfate, to decrease pH. According to the same decree the secretariat function for the Council is assured by the Ministry of Public Works. Volatilization of propargyl alcohol from moist soil surfaces is expected to be substantial, given an estimated Henrys Law constant of 1.1 106atm-cum/mole [140]. WebUSA FROTEC technology inc are established in unite states, headoffice is located in florida. MSF is a relatively cost-effective treatment method with plant life expectancy of more than 20 years [235]. In fact, bigger is better when it comes to well pressure tanks because they wear out more slowly with fewer startups and longer run times. [10], In 2011 82% of the population of Morocco had access to an improved water source. This water is subsequently produced back to the surface in the early stages of development. 562566, 1983. M. McLaughlin, Fate of hydraulic fracturing chemicals in agricultural topsoil, in Proceedings of the American Chemical Society National Meeting, Denver, Colo, USA, March 2015, http://presentations.acs.org/common/presentation-detail.aspx/Spring2015/ENVR/ENVR021a/2139634. This results in the formation of foam on the water surface which is skimmed off [244]. R. Hodge, Crosslinked and Linear Gel CompositionChemical and Analytical Methods, EPA's Study of Hydraulic Fracturing and Its Potential Impact on Drinking Water Resources, 2015, http://www2.epa.gov/hfstudy/crosslinked-and-linear-gel-composition-chemical-and-analytical-methods. 8, pp. 6% of the rural population used shared latrines, and 38% were estimated to defecate in the open. Were transparent about data collection and use so you can make informed decisions. Since 1950 SMD also managed a vital bulk water transfer project: The supply of water from the Oum er-Rbia river to Casablanca. J. Bauder, The Role and Potential of Use Selected Plants, Plant Communities, Artificial, Constructed, and Natural Wetlands in Mitigation of Impaired Water for Riparian Zone Remediation, Montana State University, Water Quality & Irrigation Management, Bozeman, Mont, USA, 2002. About half of the MWD's imported water comes from the State Water Project and half from the Colorado River both of which have become "extraordinarily stressed by prolonged drought exacerbated by climate change," the agency said. Ponds are usually covered with netting to prevent problems to migratory waterfowl caused by contaminants in OGPW [189]. Greater viscosities increase fracture width so higher concentrations of proppant can be injected, fluid loss is reduced, proppant transport is improved, and friction pressure is reduced [62]. A process for converting oilfield produced water into irrigation/drinking quality water consisted of air flotation, clarification, softening, filtration, RO, and water reconditioning [227]. P. Xu and J. E. Drewes, Viability of nanofiltration and ultra-low pressure reverse osmosis membranes for multi-beneficial use of methane produced water, Separation and Purification Technology, vol. 1, pp. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF) fluids into the formation. Reverse osmosis desalination is a process that removes salt from water by creating a barrier between the water and the salt particles. WebA ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that uses a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons. In urban water distribution it increased from Dirham 0.9bn to 1.5bn, in rural water supply from Dirham 0.5bn to 0.8bn, in water production from 0.3bn to 0.6bn, and in sanitation from Dirham 1.1bn to 2.8bn. D. Sontag and R. Gebeloff, The downside of the boom, The New York Times, 2014, http://www.nytimes.com/images/2014/11/23/nytfrontpage/scan.pdf. Remaining challenges include a low level of wastewater treatment (only 13% of collected wastewater is being treated), lack of house connections in the poorest urban neighborhoods, and limited sustainability of rural systems (20 percent of rural systems are estimated not to function). 199, no. The US$1bn program initiated in 1995 aims to reach 12 million people until 2010. The California Public Utilities Commission has just released a draft decision to revise California's net energy metering tariff. An evaporation pond is a large body of water that is designed to evaporate water by solar energy [187]. 40, no. But, hopefully Ive made the point clear. 1, pp. The Ground Water Protection Council, Making water produced during oil and gas operations a managed resource for beneficial uses, in Proceedings of the Ground Water Protection Council Produced Water Conference, Colorado Springs, Colo, USA, October 2002, http://www.gwpc.org/sites/default/files/events/Agenda.pdf. The solution contains high concentrations of dissolved constituents and is drained from the ice. When the average EC of the uppermost soil is > 35,000uS/cm, soil removal and replacement may be more economical than treatment [160]. WebEcosystem services are the many and varied benefits to humans provided by the natural environment and healthy ecosystems.Such ecosystems include, for example, agroecosystems, forest ecosystem, grassland ecosystems, and aquatic ecosystems.These ecosystems, functioning in healthy relationships, offer such things as natural pollination of D. J. Rozell and S. J. Reaven, Water pollution risk associated with natural gas extraction from the Marcellus Shale, Risk Analysis, vol. We are here to help you out. The of thioglycolic acid is 3.55, suggesting that it will exist almost entirely in the anionic form in soil and will therefore not sorb to clay and organic matter [46]. Commonly used clay stabilizers are choline chloride, potassium chloride, and tetramethyl ammonium chloride [46]. The law also provided the legal basis for the establishment of river basin agencies for integrated water resources management, inspired by examples of such agencies in France and Spain, among other countries. J. Pichtel, Fundamentals of Site Remediation for Metal- and Hydrocarbon-Contaminated Soils, Government Institutes, Rockville, Md, USA, 2nd edition, 2007. Chemicals are not required for this technology except during cleaning of membranes [83]. "We are in a critical time with the Colorado River," Houston said. In urban areas one-time connection fees for water and sewer connections are paid to the respective service provider. They range from private companies in the largest city, Casablanca, the capital, Rabat, Tangier, and Tetouan, to public municipal utilities in 13 other cities, as well as a national electricity and water company (ONEE). Getting a larger well pressure tank will not increase your water pressure beyond the pumps pressure control setting. A. Fakhru'l-Razi, A. Pendashteh, L. C. Abdullah, D. R. A. Biak, S. S. Madaeni, and Z. Media do not exceed 10cm in diameter to prevent clogging of pore spaces when sloughing occurs [228]. This is a move intended to improve pricing by aligning energy prices with the electric grids capabilities around the clock. 131, no.
