AdBlue has a national network of manufacturing plants spread across Australia where Adblue is manufactured for distribution. The process requires water of a demineralised specification for the end product to meet industry standards. The existing process used by the company was n 8 inch front-end RO unit with a mixed Bed Resin to do a final polish on the resulting permeate.
The extreme scheme water provided by the different municipalities at their different plant sites coupled with the less than ideal RO set up plants meant the resin bed as the final polish was being “spent” regularly. Regenerating mixed Bed resins is a very involve process which for a small business of AdBlue size was very intricate and too specialised. AWS was through a long-term association with AdBlue was asked to spear head the project whereby a more efficient and economical way of providing permeate water minimal reject water sent to waste could be developed.
AWS successfully designed; fabricated; installed and commissioned such a plant which produced very high quality demineralised water without the use of mixed bed resin and minimised waste to less than 25% of total water produced; down from 50% with a pay ack period of under 3 years. The design utilised there off the shelf small all-purpose RO units with high rejection 4 “membranes which produces a capacity of up to 30KLD. The design utilised a 2 pass RO system and a third RO system to recover the waste stream and use the permeate from the waste recovery to be sent to the front end of the plant and mixed with the town water supply.
Maintenance costs have also been drastically reduced. The plant is completely automated with an integrated electrical system monitoring the water levels in the tanks in each part of the process and ensuring product demand is met.
