It is subsidiary Company of â € œ PRISMA- DOMIâ € � SA Technical Co., working on â € œ green energyâ € � business.
Based in Athens, since 1996 with President of the Board is Mr. Ioannis Theodorakopoulos, a businessman & chemical engineer, working on â € œ green energyâ € � business.
History: There is a patent for all such systems, from German State.
Licenses throughout EU countries.
Scientific Institutes: Institutes of Technology Of Aachen & Athens, Institute of Nuclear Research Of Athens.

Problems: Brackishness of underground waters, especially in insular or costal areas. Livability for all other cases of water treatment. Contamination of water with nitrates, pesticides and heavy metals. Shortness of potable water resources.
Solution: Development of an innovative hybrid system for desalination and removal of harmful substances. High quality potable water production, without any further chemical treatment. Use of renewable energy sources, for better efficiency.

Reverse osmosis is considered as one of the most effective and financial feasible methods for the desalination of waters containing high Na+ and Cl- concentrations, like sea and brackish water.

Usual pretreatment of RO feed water includes:

Chlorination for microorganismâ € ™ s disinfection.
pH regulation for the prevention of Calcium Carbonate scaling.
Adding of antiscallant substances for the prevention of insoluble Calcium and Barium salts precipitation.
Dechlorination ( using NaHSO3 ) for protection of membranes from the free Chlorine.
Adding of poly- electrolyte for colloids precipitation.
Adding of active carbon filter for microbial and fungus cells.
Minimization of membrane scaling and fouling.
Long membrane life.
Lower membrane replacement costs.
Easy access to all membranes films.
Less or no chemical pretreatment of the feed water ( up to 15% / min SDI) .
Better membrane cleaning.
Higher efficiency with lower pressure drop, due to the advanced flow pattern.

Key Competitive Advantages:

Desalination and removal of harmful substances ( nitrates, pesticides, heavy metals, etc) in one pass.
Production of potable water without any further chemical treatment, that misquotes its quality.
Reduce in the energy consumption up to 15% .
Up to 35% increase in the water production.
Retention rate of ions and other harmful substances, that exceeds 97% - with the retention of nitrates exceeding 99, 5% .
Further decrease in the energy cost and higher System performance, by using solar energy or other mild or renewable energy resources.
Use of DT modules with high tolerance in relation with the feed water specifications.
Flexibility in the use of the unit as Hybrid or as RO.
Higher operational life of membranes.
Use of natural rocks bed in order to enrich the desalinated water with the necessary trace elements.
Tele-monitoring System to ensure the reliable operation of the System.
Electricity power needed can be reserved by solar power units!

Thank you,
