Uneqileen – a subsidiary of Global Environmental Solutions – GES – has registered a patent for a unique hard industrial waste-water treatment development based on a magnetic separator. Swift, effective treatment may be achieved at low cost while fulfilling the strictest standards

Global Environmental Solutions (GES) engaged in treatment of water and waste-water through Uneqileen, has developed unique treatment methods for hard industrial waste-water containing high concentrations of various organic substances, detergents, phenols, chlorinated hydrocarbon, heavy metals, etc. Company scientists have developed a unique treatment process for industrial waste-water based on magnetic separation and have patented this process.

Magnetic separator – swift, efficient treatment

Removes suspended substances
At the first stage of the treatment, sludge is created by adding coagulants and a mix of flocculants including magnetic particles. The suspended substances, heavy metals and some colloidal substances are removed by sedimentation during the treatment. At the end of this stage the sludge is separated from the liquid by the magnetic particles. The process is extremely fast and efficient, ending with compact, hydrophobic sludge.

Catalytic oxidation of organic substances
The second stage of the process is catalytic oxidation to treat the dissolved organic substances remaining in the liquid after the sludge is separated. Many organic substances do not break down by regular oxidation. Most known oxidation processes are extremely slow or heat consuming, raising their cost. Uneqileen's development is based on a unique catalyst that enables, together with the oxidizer, fast and efficient oxidation of organic substances. Oxidation takes place at ambient temperature and lasts several minutes only. The water resulting from this oxidation process is treated at COD levels 80% below its level preceding treatment. (COD is one of the analytical parameters that indicates concentration of organic substances in water). The catalyst is separated from the treated water using a magnetic separator and remains in the reactor to be used recurrently for hundreds of additional batches of waste-water.

Polishing stage
At the end of the process, a pillar of active carbon is used to remove remains of oxidizer and end the oxidation process optimally. The three stages may be used to treat many diverse types of waste-water coming from different sources. The treatment method is modular and may be adapted to both type of original waste-water and composition of treated water required at the end of the process.

Developing existing processes
Currently, company labs are carrying out feasibility tests on dozens of different types of liquid waste from various plants, including pharmaceutical, chemical, oil, paper plants, spray plane washing water, saline solutions, etc. Successful pilot tests have been run at the company's Acre pilot facility on some of these waste-water types. Low cost and high product level solutions were found for most waste-water that reached the labs. Company scientists continue to develop additional catalysts to increase utilization of the oxidation process and improve the submersion process.

Advantages of the technology

Removes over 90% of pollutants
Applied to several pollutants simultaneously
Simple and easy operation and maintenance
Uses available chemicals
Relatively low investment
Low operation and maintenance costs

Fulfills stringent standards
The objective of Uneqileen of the GES Group is to use advanced methods to treat waste-water while fulfilling gradually stricter standards for quality of water for waste-water, irrigation or streaming to the sea. The company maintains low costs adapted to the industry that may save plants tens of thousands of dollars annually compared to the cost of removing waste-water to Ramat Hovav or other similar sites.
