Effluent Quality
This product is designed to achieve an effluent quality of 20mg/l BOD5, 30mg/l Suspended Solids and 20mg/l Ammonia. The Klargester BioDisc® can also be configured to produce better standards of effluent quality with Ammonia levels as low as 5mg/l being achievable. For expert advice for design, support and further information call 01296 633033.
Applications, where commercial catering takes place, will generate significant volumes of grease which should not be allowed to enter any treatment system.
The treatment of sewage from applications other than domestic housing can often demand special precautions, therefore specialist advice should be sought from Klargester.
