SOLVIA Bio 5 Long septic tank

The larger SOLVIA Bio designs are chosen for a house with permanent occupancy, where wastewater arrives day after day. Treatment is biological and takes place in a single vertical housing: in the lower zone, denitrification proceeds at low oxygen content; in the aeration zone, fine-bubble air and the bio-media sustain the oxidation of organics and ammonium; in the settling zone, the water separates from the activated sludge.

The more users there are in the house, the more important it is to choose the location in advance: the vertical housing occupies a small area, but access to the unit for servicing should be left clear. The method of discharging the purified water — by gravity or pumped — is determined by the terrain of the plot. Installation, commissioning and service are carried out in Georgia.

SOLVIA Bio 5 Long version: serves up to 5 people, capacity 1 000 l/day.

By capacity it sits between SOLVIA Bio 4 Long (800 l/day) and SOLVIA Bio 6 Long (1 200 l/day): 1 000 l/day.

One step down by capacity — SOLVIA Bio 4 Long: serves, people up to 4 instead of up to 5. One step up — SOLVIA Bio 6 Long: serves, people up to 6 instead of up to 5.
