Effluent Treatment Plant at PTA Complex
Location : Hazira, Surat
UPL EEL have executed another project of RIL for setting up of ETP to treat 7.5 MLD of waste water generated from the PTA Plant of RIL Hazira, b y providing utilizing the Up flow Anerobic Sludge Bed Reactor technology.
The UASB technology utilizes the high COD reduction capacity of especially cultured granular biomass which leads to small size reactor, minimum use of energy and elimination of secondary clarification systems.
In addition the plant efficiently converts the destroyed COD to Biogas, which can be used as fuel saving large amount and minimizing the payback period Also, the Anerobic removal of COD by the granular biomass results in minimum generation of fresh biomass, to the extent of only about 2-3 % of COD destroyed as against 25 % above in Conventional Activated Sludge Systems. This minimizes the sludge disposal cost.
The main features of the proposed ETP includes 2 nos. of UASB reactors , Specially designed 3 phase separators with biogas domes, a min/max type influent distribution system, a conditioning tank for mixing the fresh effluent with micro nutrients and recycle stream, the micro nutrient dosing systems and a biogas holder.
The plant is designed for a COD input of 36 tons/ day , with guaranteed removal efficiency of 71 % and Biogas generation of 480 Nm3/hr.
UPLEEL has set up first Effluent Treatment plant on EPC basis based on the arsenic removal system using the sodium sulfide rout for its prominent client Sterlite Industries Limited, Tutikorine, Tamil Nadu.
Other special feature
This kind of project has been executed first time in India.
