Most of Israel's wastewater including sewage is now recycled using reclamation, treatment and purification methods pioneered by the country's companies. Israel has devoted more resources to this topic 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 Easily Ranked Top in Recycling
Israel Easily Ranked Top in Recycling
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 80% of the country’s drinking water and 70% of all Israel’s water supply, leads the way in developing innovative technologies. Today, Mekorot is responsible for treating 30% 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 60% 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 over 30 years and is the largest of its kind in the world. The plant purifies about 130 million cubic meters annually, representing the wastewater of nearly 3 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, which purifies 37 million cubic meters per year, serves a population of 450,000 and uses similar technology and methods to the Shafdan site. The Greater Jerusalem project in the Sorek Valley purifies 23 million cubic meters of water per year.
Additional sites in Israel serve the cities of 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.
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. Triple-T specializes in the design, construction and operation of wastewater treatment plants.
Advanced Wastewater Treatment
Israel is easily ranked first in the world in recycling water for agriculture.
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 wastewater 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’s shares are traded 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.
Amiad merged with Arkal Filtration Systems, which 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.
