Industrial Wastewater Treatment (ETP)
AECL successfully introduced local technology based Wastewater Treatment plant in Bangladesh in 1997. This technology is very cost effective in terms of chemical consumption, energy efficiency and space consumption. Since last ten years AECL has installed large number of Effluent Treatment Plants (ETP) in different industries of Bangladesh. The activities involved the design, construction supervision, commissioning, monitoring after commissioning and training for company staffs regarding the operation & maintenance of ETP.

Recent Development of AECL in ETP
AECL has been successfully implementing effective biological treatment in the ETP which doesn’t generate any sludge or uses chemicals. So, the treated water from the ETP is very polished and the discharged water quality is much lower than the Bangladesh standard for inland surface water.
The major advantage of this biological ETP is that the clarity of the treated water is very good compared to conventional ETP which helps the industry to go for tertiary treatment (recycle & reuse) easily without having major problem of membrane fouling and minimal rejection rate. Even the client can reuse the water after Nano & Ultra filtration (controlling the rejection rate to 50%) in which the rejection water parameters should be below the Bangladesh DOE standard for discharge into surface water body, so, there is no need for evaporation.
