EFFLUENT AND WASTE MANAGEMENT
The left over resicfue and discharge known as spent waste is sent to the Effluent Treatment Plant which consists of settling pits, cooling, pumping and digesting equipment. The Effluent Treatment Plant is based on the latest techn’ology from the world renowned French company Porserpol.
Porserpol specializes in the design and erection of installations for treating and recycling liquid effluents. The spent wash from the distillery is collected in cooling and settling pits. After the desired temperature is reached, two sets of pumps transport the spent wash to four digesters. Every digester is an independent functioning unit where anaerobic process produces biogas.
This biogas is burnt in boilers to produce steam and in power generation for the distillery. The degassing tank serves the purpose of eliminating gases coming along the liquor which overflows from the digesters saturated with bio gas. After degassing the biomass is separated from the treated stillage which is collected in circular tanks and overflows due to gravity into the sewer system along with excessive amounts of water to control its biological specifications. The remaining sludge in the clarifier is then collected by means of a suction scrapper and is reused and re-circulated to all the digesters by means of pumps.
