BIOEPURO
sewage treatment plant per liquami

The unit is completely pre assembled and can be easily installed on board by using a crane. Every unit is duly tested before delivery, and our skilled engineers will start-up the plant once installed.

Normally, only the sewage from W.C. and urinal passes through the wole plant, while the water from washbasins, showers, etc. Is passed directly to th echlorination tank where eventually, sterelization takes place, because it does not need any biological treatment.
The sewage to be treated, enters the pre-aeration-separation tank where, through special diffusers, air is added, in order to supply the neccessary amount of oxigen for the breeding of micro-organisms required for the process.
At this stage, all bio-degradable matter; a macerator of our own design can be installed. After this, the pre-treated sewage passes to the aeration thank where the bacteria mass in increased further, and, after a sufficient retention period, is delivered to the settling tank by an air-lift.
This air-lift can be considered as the heart of our plant and because its output is self-regulating, it is possible to obtain an almost costant output, indipendent of the sewage supply rate.
