Aquatech is a leader in the water industry. One of our areas of expertise is wastewater reuse. We have completed some of the first large-scale projects in industrial reuse. One of these large-scale projects was for the Mumbai International Airport.
As a part of airport’s massive expansion plan, a 10 million liters per day (MLD) wastewater recycle project was contracted to cater to the growing requirements of the expanded airport. Due to increasingly strict environmental regulations, the treatment of raw sewage wastewater is required before it is allowed to flow into the natural ecological system. As the airport has a lack of fresh water availability for its requirements, it needs to recycle and reuse the treated sewage water for its operations, such as toilet flushing, horticulture, and HVAC cooling makeup water. Aquatech was awarded an EPC contract to supply a 10 MLD sewage treatment and recycle system on a complete turnkey basis for the new airport terminal.
The MIAL plant is an integration of many technologies – a combination of biological treatment followed by advanced tertiary treatment based on UF and RO processes. The primary treatment consists of coarse and fine bar screens followed by a grit chamber. The secondary treatment consists of an AECOM Cyclic Activated Sludge System (CASSTM) sequencing batch reactor (SBR) biological treatment technology followed by disinfection. The tertiary treatment includes a QUA® ultrafiltration (UF) pretreatment system followed by a reverse osmosis (RO) system, after which the water is reused and distributed for the airport’s various purposes.
The sewage wastewater treatment plant has been in operation for more than a year and is successful due to its innovative design and integration of optimized and advanced treatment technologies.
