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.

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
