Treated Sewage Effluent (TSE) until recently was a water source reserved mainly for irrigation and was not marketable for other uses. Since the regulation changes in the region TSE has gained momentum, namely in the district cooling industry. The use of TSE can significantly reduce capital costs and operational costs, whist reducing the demand on fresh/potable water.
Qatar Cool has implemented TSE in all three cooling plants in the West Bay district, two of which receive direct TSE and the third via an onsite Reverse Osmosis (RO) plant.
TSE and waste water have remarkable potential and benefits in supplementing the water demand, in such industries. Provided the TSE quality meets the water quality and quantity requirements for the nature of the system. Generation of TSE is significantly economical and consumes less energy compared to potable water.
Qatar Cool are seeing the benefits of switching to TSE and anticipate the positive long-term effects.
