THEORY OF OPERATION – HOW IT WORKS ?The operation of the BIOCON systems is simple and very

effective. The system usesAir (oxygen) for the rapid oxidation of the organic material combined with chlorine (either 5% or 14%

concentration recommended) for the germs elimination. The oxygen and the added chlorine meet in the suction line of the recycling current and are working in an aggressive reaction under strong turbulence on the organic matter, the surface of which has been previously optimally enlarged by a macerator to solids of maximum 0.5 mm dimensions. This makes a quick reaction possible, which has been accomplished in 12 minutes of continuous process (thorough mixing and continuous recycling and cutting in the treatment tank) for the quantity of sewage accommodated at each batch. All effluent is passing through a filter membrane ,and backwashed sludge is expelled to a separate sludge tank.

� Biocon’s automatic self-cleaning filter-membrane is a motorizedstrainer designed for the continuous removal of entrained solidsand especially sewage sludge.

� With an automated control system monitoring the straineroperation, cleaning is accomplished by an integral backwashsystem

� A small portion of the screen element is isolated and cleaned byreverse flow. The remaining screen area continues to filter-providing uninterrupted flow.

� Thus only a small amount of the liquid being strained is used tocarry out away the sludge.

� Maximum effective flow area and maximum operating efficiencyare maintained thought service life.

� Maintenance costs are reduced drastically due to non cloggingand stapling material .

� Long lived straining element provides provides reduced operatingcosts over entire service life.

� Very efficient, effective sludge collection at filter interface

The dirty fluid enters the filter ‘sBottom chamber , passing radiallyThrough the sealed screen element .

Backwash cleaning is accomplished By utilizing the pressure differentialBetween line pressure and outlet.

When it exceeds 0,5bars backwash Valve opens the system to atmosphere.

Sludge are flushed from the screenSegment to the backwash arm andThen though the valve to the sludge tank.
