Quality objective

High-quality treated water

The water quality obtained after Biosep™ is fully in compliance with stringent environmental standards and meets as well municipal and industrial needs.
Biosep™ achieves high removal of carbon and nitrogen pollution and retains almost all of the suspended matter. At the same time, the water disinfection is performed through the membrane filtration step.
Biosep™ can be adapted to loading variations whilst ensuring consistent treated water quality.

Efficient treatment of municipal and industrial effluents:

Examples of performance for industrial effluent

	PERFORMANCES
COD	from 30 to 70 mg/l (according to hard COD)
DBO₅	≤ 5 mg/l
SS	< detectable threshold
TN (Total Nitrogen)	from 10 to 15 mg/l (according to hard nitrogen)
TP (Total Phosphorus)	< 0,5-2 mg/l
Total coliforms	5 log or ≤ 500 U/100 ml
Heat tolerant coliforms	5 log or ≤ 500 U/100 ml
Faecal streptococci D	5 log or ≤ 500 U/100 ml
Bacteriophage content	3 log

Examples of performance for municipal effluent

Biological treatment
	PERFORMANCES
COD	≥ 95 %	≤ 30 mg/l (non degradable COD)
BOD₅	≥ 97,5 %	≤ 5 mg/l
SS	< detectable threshold	≤ 5 mg/l
TN (Total Nitrogen)	As activated sludge	≤ 15 mg/l
TP (Total Phophorus)	As activated sludge	In compliance with standards
Disinfection
Total coliforms	5 log	≤ 500 U/100 ml
Heat tolerant coliforms	5 log	≤ 100 U/100 ml
Faecal streptococci D	5 log	≤ 100 U/100 ml
Bacteriophage content	3 log	3 log

Nothing to see, Nothing to smell, Nothing to hear

With its innovative and compact design, Biosep™ is easy to install in any kind of places without environmental impact, odor and noise nuisances.
