Treated Waste Disposal system
bio Uro clean system produces a fully treated wastewater, (BOD <20 mg/l;
suspended solids <30 mg/l), which is more easily absorbed into soil
strata than septic tank effluent. The percolation area should be
designed in accordance with the site suitability results and should be
fitted in accordance with population served.
typical layout of the percolation trench and raised percolation bed are
Secondary treatment chamber
liquid from the primary chamber is aerated, enabling the cultivation of
colonies of aerobic bacteria (biomass), which break down the organic
matter. Following a settling period, the clarified effluent is pumped
for discharge to the percolation area. The treatment cycle then
recommences, providing there is sufficient volume of wastewater in the
primary chamber to constitute a batch.
When there is insufficient inflow of wastewater to the primary chamber
within the cycle time, the unit switches to an alternative cycle or
‘holiday mode’. This cycle continues until adequate volume of wastewater
is detected in the primary chamber and normal operation resumes.
