A new RO polisher was designed from the ground up and integrated into the existing RO frame. The polisher was close coupled to the RO permeate stream, with the ability to bypass the polisher if required. Once the RO permeate was polished it is sent to storage. It is then utilised for the flushing and CIP of both membrane plants.
A volume metering chemical dosing system was designed and installed to provide up to five different chemical supply steams to chemicals to each of the membrane plants.
A new control system was developed and implemented. Both plants are visualised controlled through a SCADA system utilising a recipe-based approach and including a full historian. The PLC is an Siemens based architecture with the VSD drives controlled via Profinet.
