DEMINERALISED WATER FOR MINERAL PROCESSING PLANT

BACKGROUND

High quality demineralised water is produced from bore water for cooling tower and boiler feed water at a titanium dioxide plant in Kemerton.

Initially interested in a hire Reverse Osmosis (RO) plant to supplement the demineralised water supply from its existing Ion Exchange plant, this manufacturer realised the reliability and cost effectiveness of RO compared to ion exchange and decided to increase the requirement to 1,500 m3 /day for a longer hire term to replace an old Ion Exchange system. Prior to completion of the first hire term, the RO hire plant capacity was upgraded to 1,800 m3 /day and extended to a second term.

With ongoing service and support by MAK Water, RO proved to be a more efficient and reliable replacement for Ion Exchange and the contract was subsequently extended to a third term with a longer Build Own Operate (BOO) contract.

SOLUTION

• In-house design and manufacture of a 1,500 m3/day (3 trains) Brackish Water Reverse Osmosis (BWRO) hire plant, with upgrade to 1,800 m3/day
• Custom design with 316SS high pressure pipework to achieve the required treated water quality
• 3 x 33% trains for operational flexibility
• ClearAccess™ Remote Monitoring and Control
• Fast six week lead time for hire reverse osmosis plant supply
• Onsite commissioning and training of local operators, with ongoing service and maintenance
