Based Technologies - USAB for Industrial effluent
treatment
Introduction
The UASB reactor
is an economical solution for the treatment of industrial
effluent which have substantially dissolved pollutants.
It combines modern high-rate treatment technology with
simplicity of design. In the USAB reactor, special GAS-SOLID-LIQUID
SEPARATORS are mounted which enable collection of biogas
and recycle of anaerobic biomass. The avoidance of internal
packing in the reactor greatly reduces the cost of reactor
construction.
The UASB Reactor
works best when desirable micro-organisms are retained
as highly active and fast settling granules. Granular
sludge as it is known is required for start-up of such
reactors. Granular sludge is unavailable within the
country and has to be imported. RRL has developed start-up
process know-how, to produce granular sludge from non-granular
seed.

Effluent Collection
Influent Distribution
The reactor itself is RCC in modern
rectangular space-saving design, or as circular low-cost
design. The reactor may be constructed underground where
soil conditions permit considerable cost-saving
