Bio-Robi recommendation

"The EPC Bio-Robi system works on the principle of extended aeration with long retention line and the technology is the most innovative and advanced in its kind world wide.
Since it's installation till today the system works on high standard and without any malfunction. The received effluents are according to all standard requirements and are used to water the plant which are at  Has'hiv'a  interchange.The maintenance team of EPC who maintains the system on a regular basis is reliable, serious and professional.
I'm very satisfied using the system which conforms to all applicable laws and regulations and also from the warm and technical support all along the years"

Purification Process

1. The Mechanical Stage: collecting sewage inflow into first tank - The system develops un-aerobic conditions through preliminary sedimentation process. This process enables 40%-50% reduction of the BOD & TSS


2. The Biological Stage: Treated inflow inside tank "A" gravitates to the purification tank – This stage is based on extended aeration process using long retention time. The inflow is mixed with compressed air in special static mixing chamber situated on top of the tank. As a result, the organic solids are being disintegrated into small particles which multiply its surface as well as the organic load and purify the sewage. Unlike other systems, Bio-Robi excess sludge needs to be removed only once in a few years.

3. The Clarification stage: Purified inflow gravitates to secondary sedimentation tank – All residual solids which sink to the bottom of the tank are being
