RECLAMATION AND PURIFICATION

Recycling Replenishes Israel’s
Water Resources



Reclaiming, Treating and Purifying Wastewater Provides More Water for Agricultural and Industrial Use



Israel is the global leader in the recycling and purification of wastewater. The country has devoted more resources to the development of wastewater treatment and reclamation than any other country in the world in proportional terms.
Located in an arid region with limited water resources, the threat of pollution to diminishing resources, and a growing urban population with high levels of water consumption and wastewater production, prompted Israel to develop technologies for wastewater reclamation and purification.

Israel Ranked Number One
Israel is easily ranked first in the world in recycling water for agriculture. 75% of sewage is recycled for agriculture with Spain, ranked second in the world, recycling 12% of its sewage for agriculture The Mekorot national water company, which supplies 90% of the country’s drinking water and 80% of all Israel’s water supply, leads the way in developing innovative technologies. Today, Mekorot is responsible for treating 40% of Israel’s wastewater (190 million cubic meters annually out of a total of 475 million cubic meters a year) in nine plants of varying sizes. Mekorot reclaims about 75% of Israel’s reused effluents. Even though the reclaimed water is as pure as the country’s freshwater supplies, the purified water is used for agricultural use rather than household consumption.

Major Wastewater Plants
The Dan Region Treatment and Reclamation Plant at Shafdan (south of Tel Aviv) is in operation for 30 years and is one of the largest of its kind in the world. The plant purifies about 130 million cubic meters annually, representing the wastewater of 2.4 million residents living in the Greater Tel Aviv region’s 13 municipalities. This figure represents nearly 8% of Israel’s entire water consumption.
Other major treatment and reclamation plants in Israel include the Greater Haifa project at the Kishon complex north of the city. This plant serves a population of 450,000 and uses similar technology and methods to the Shafdan site.
Additional sites in Israel serve the cities of Jerusalem, Beer Sheva, Netanya, Eilat and Afula. Nearly every major city in Israel already has, or is planning reclamation activities. With a proven technology that is highly cost- effective, industry has joined reclamation bandwagon as well.

Implementing Projects
Tahal Group and Rimon Consultancy and Management Services, part of the Gaon Agro-Industries Group, are leading companies for planning and managing wastewater reclamation projects. Ritmo Engineering Consulting also has extensive experience in this sector.
GES Global Environmental Solutions also specializes in water reclamation and purification projects. In addition to planning and managing entire projects, the company offers compact purification facilities including mobile, water tank and bio-circle purification systems. Another company in this sector, A.L.D. Environmental Protection, a partnership between Elco Holdings and Lesico is also a leader in wastewater treatment solutions and has the capabilities to build and operate cost-effective, efficient and safe plants.

Advanced Wastewater Treatment
Side-by-side with this expertise in water reclamation, some Israeli companies specialize in all aspects of sewage treatment. For example, Aqwise develops advanced technologies for capacity increase and nutrient removal in activated sludge processes of wastewater treatment plants.
TreaTec21 Industries has developed two advanced water purification systems:
an advanced electro-flocculation system for wastewater filtration and an electro-flocculation system for wastewater settling treatment. Bio-Dalia Technologies has developed a method for bio-degrading contaminant in wastewater.

Drinking Water Quality
Extensive water quality monitoring is performed to keep an efficient and safe wastewater reuse system at all the sites in major Israeli cities where there are wastwater recycling projects. Although modern treatment technology can produce reclaimed water meeting the purest internationally recognized drinking water standards, right now, public acceptance considerations prevents the use of highly treated effluents for household purposes.
Worry over waterborne diseases and pollution have been offset by the development of new methods for preventing and detecting contamination. Even so water quality is one of the world’s pressing public health concerns. Consequently, innovative filtration techniques, as well as chlorination and other treatments have been developed to improve existing water sources and meet increasingly stringent, international, microbiological water standards.

Leading Filtration Systems & Technologies
Many Israeli companies are global leaders in this sector, developing and manufacturing systems that either improve the quality of fresh water or enhance the purification of reclaimed wastewater.
Amiad Filtration Systems has developed fast, efficient, self-cleaning technologies ensuring a continuous flow of filtered water. Owned by Kibbutz Amiad in Israel’s Upper Galilee, Amiad recently enjoyed a successful IPO on London’s Alternative investment Market (AIM). Amiad offers suction scanning technology, thread technology and a range of filter elements that have been installed in thousands of filters and filtration systems worldwide.
Arkal Filtration Systems is a market leader in the filtration of water containing high loads of biological material (surface and sea water). The company holds a 25% share of the global micro-irrigation markets in agriculture and landscaping. The company’s capabilities cover the entire range – from initial concept, design and engineering to supply, installation and commissioning of water filtration and treatment systems for agricultural, industrial, commercial and municipal market segments.
Nirosoft provides clients with a wide range of high-tech water treatment solutions utilizing the most advanced technologies. These include: membrane separation technologies; reverse osmosis, ultra- filtration and nano-filtration; ultra-pure water (UPW), water demineralisation: EDI, ion exchange. Nirosoft also specializes in dissolved air flotation, and media and activated carbon filtration.
Yamit E.L.I. Water Treatment Systems is a leading provider of water treatment systems and water filter solutions for industry, the public sector and agriculture. The company’s water treatment technologies include reverse osmosis and membrane systems, softeners and ion exchange systems and UV systems. Yamit’s filter products include media and multi-media systems, automatic hydraulic and electric screen systems, sand separator and sugar liquid systems.
Gavish Control Systems focuses on quality control, offering computerized packages for enhancing the quality of farming water, while Tamhil develops and markets solutions that prevent and inhibit lime-scale damage and corrosion in pipes while saving energy.
Sinomed Foltration develops, produces and markets equipment designed to solve particular problems in wastewater treatment. A high efficiency up-flow filter designed to provide a very efficient solution to difficult problems in the treatment of municipal, industrial and agricultural wastewater. ATLANTIUM develops and provides innovative water disinfecting solutions that help businesses and municipalities build, expand and operate water-intensive processes.
ATLANTIUM’s field-proven solutions take UV water disinfecting to much improved levels. This is accomplished through a cost effective, environmentally friendly process that delivers unprecedented micro-bio in-activation at industrial and municipal water flow rates. The day may still be very far off when it is possible to completely eliminate water contamination, but a new generation of effective filters and related technologies is significantly reducing the public health concerns.
