A beverage facility located in South India needed a future-proof and efficient water and wastewater treatment plant. The company decided that a new wastewater treatment facility would be the best option to treat its wastewater and reuse the effluent back within its plant.
Working with SUEZ the beverage company created a new water treatment plant, at which raw water is fed to the raw water storage tank followed by specific chemical dosing. Ferric chloride, polymer and lime are used as coagulant for alkalinity removal. The water then goes through a clarifier, Multimedia filtration (MMF) and Activated Carbon Filtration (ACF); and subsequently flows from the outlet of individual cartridge filter to the suction high-pressure pumps. From there, pressurized feed will pass through an array of low-energy nanofiltration (NF) membranes. The filtered water from the storage tank is pumped to an UV Sterilizer for the removal of microorganisms present in the water. The plant also includes a b recovery system using MMF filter.
The new water treatment plant includes Membrane Bioreactor (MBR) technology to treat wastewater for reuse purposes. SUEZ’s ZeeWeed* 500D MBR solution was suggested because it can operate with the membranes directly in the bioreactor tank to drastically reduce the required plant footprint and eliminate the need for secondary clarifiers.
The effluent from the MBR process is then fed into a reverse osmosis (RO) system and treated further for
reuse. The RO system used to treat the MBR permeate is designed for wastewater applications with stage wise cleaning. The MBR permeate of 260 m3/day is pumped from the treated water tank through the RO feed pump. The system is designed for the recovery of 70% to yield the permeate of 180 m3/day with less than 2100 ppm. The system package also includes the necessary dosing system and Clean in Place (CIP) System.
The reject from the RO system is further directed to the tank through the drain channel and collection sump.
