Novel Efficient Water Technologies

Wastewater Recycling and Reuse: The Renovation of WaterWastewater recycling provides solutions for multiple problems. By recycling used water, fresh wateris "freed up" for domestic needs, which is less expensive than developing new water resources.Additionally, water recycling solves waste disposal problems and reduces fertilizer requirements.Israel's Shafdan Treatment and Reclamation Plant, isone of the largest of recycling plant in the world. Theplant is responsible for:Israel's Recycling RecordIsrael is the largest water recycler in• Treating wastewater originating from nearly 2.3million residents in Tel Aviv's 13 municipalities –which represents 8% of Israel's entire waterconsumption.the world, with a recycling rate of75% - the second largest waterrecycler is Spain, with only a 12%reuse rate.• Purifying approximately 130 million meters 3annually of wastewater for irrigation purposes.• Providing treated water to the Israel's desert region for irrigation uses.Streamlining Innovation:Israeli companies have developed a variety of innovativefiltration technologies to allow the reuse and recycling ofwastewater and prevent water borne diseases,contaminants and pollution, including:• Magnetic-Based Water Treatment - A process thatuses magnetic particles to separate toxic organicsubstances, such as oil, detergents, phenols, dyesand heavy metals from the water whichsimultaneously produces a magnetic and hydrophobicsediment.• Electro-Flocculation System – A method thatspeeds up the settling process of water by releasingmetal electrodes with positively charged electrons topull the negatively charged particles downward. Thisprocess is estimated to reduce operating costs by15%.Israel has developed a uniquemethod of water purification usingthe geological structure of landadjacent to the purification plant. Thetreatment plant provides advancedbiological treatment of wastewater,including the removal of nitrogenand phosphorous, by injecting theeffluents into the sandy layers of landsurrounding the plant and attaining aneffective biological filtration of thewater. This water is then retrieved andtransported to the Negev.• AGAR (Attached Growth Airlift Reactor) - A system that significantly increases surface area ofbiological purification treatments by using biomass carriers and isparticularly cost-efficient as it does not require expanding the plant'scurrent infrastructure.10
