Sewage Treatment Plant for 5 - 30 E.I.

Compact Sewage Treatment Plants for 5-30 Equivalent Inhabitants

 

 

Compact biological treatment suitable for hotels, villages, campsites, camps, factories, shopping malls, marinas, building complexes, schools etc that not served by the main sewer.This system is specifically designed for buildings where black waters and grey waters are not collected in separate lines but are out flowing to the treatment system as mix sewage liquor from a single line.
The plant Is type “activated sludge”, which processes and purifies the water using the method of aerobic biological treatment as all the major biological purification of urban cities.

The system is cleverly conceived and designed by our technicians to process mixed (mix) waste water from toilets, kitchens and laundries.

 

 

The System Consists Of :

 

1. DOUBLE CHAMBER SEPTIC TANK

The double-chamber septic tank is installed for the removal of settleable organic and inorganic solids by sedimentation, and the removal of floating materials.

The tanks are entirely made in polyethylene and hare designed with a man-hole with a screw-on cover for inspection.

The primary treatment of sewage is important if the waste water from toilets mixed with elements of the kitchen and the laundry in a single drain line

2. ACTIVATED SLUDGE TREATMENT

(oxidation-sedimentation-sludge stabilization-chlorination)

The depuration is performed in a multi-stage process whose phases of biological oxidation, sedimentation, digestion and disinfection.

The biological oxidation phase occurs in presence of aerobic bacteria and protozoa which consume biodegradable soluble organic contaminants and bind much of the less soluble fractions into floc particles.

The oxygen necessary to the biological processes is supplied by a silenced membrane type air compressor positioned externally.

Sedimentation is the final step in the secondary treatment stage with the objective to settle out the biological floc and produce a supernatant with very low levels of organic material and suspended solids.The system has a sedimentation compartment designed to optimize the hydraulic retentionfor a time suitable to allow the sludge settlement. The activated sludge and the solids settle to the base of the plant while the clarified supernatant liquid flows towards the final stage of it..
The biological process is designed to minimize the quantity of sludge which needs to be removed periodically from the system for separate disposal in designated pits.Clarified water is discharged through a contact compartment where an active chlorine tablet is positioned to disinfect and remove any remaining pathogens from the water.
