Today in the decentralized sector mostly small water treatment plants for new construction and retrofit uses. SBR is an acronym and stands for "sequencing batch reactor", which freely translated continuously one after the other numbers Einbeckenbelebungsanlage states.

This question is arithmetically clearly linked to scientific methods to calculate.
A SBR small waste water treatment plant as for 8 pe (pe = population equivalent value) is required at 50% Inrush of the air compressor and a water depth of 120 cm, a capacity of 100 liters of air / min.

"100 liters of air per minute is only an average"

The oxygen enrichment in these systems is usually on air compressors and Plug aerators. Some systems also work with submersible motor fan, with a propeller equipment. Submersible motor fan only have about 25% efficiency compared to an air compressor (as demonstrated by an accredited independent testing laboratory), see table "Features - 400% more power." How much oxygen is needed for the purification process?

A continuous run of units does not make sense from energy and material-technical reasons. Ideally, the air compressor claimed in medium power load. This achieved optimum efficiency and life-time of all aggregates. Smaller compressors in SBR plants make little sense, because sufficiently dimensioned installations give you the security and the right investment decision.
