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.
Industry classification:
Pollution control
Primary/Secondary:
Secondary
Product type
: Industrial
Manufacturing:
Waste water processing
- Process used: Secondary
Primary/Secondary
- Major Machinery
used: The heart of RRL UASB reactor consists of a
specially designed modular gas collection system made from
corrosion-free FRP and Steel … Designed on computer
for optimum cost-performance, it is uniquely combines
3 FUNCTIONS:
- Gas Collection
- Sludge Recyle
- 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
