As part of the Woodman Point Washplant upgrade, Delkor was awarded the contract in October 2006 to design, supply, install and commission a horizontal vacuum belt filter with an effective filtration area of 131m2. Size selection was based on previous testwork performed at Delkor’s Sydney laboratory in March 2006.
The Cockburn Cement, Woodman Point Washplant is located on the west coast of Australia, 30km south of Perth. The horizontal vacuum belt filter will be used to filter and wash sand claimed from the Indian Ocean to provide the essential material for Cockburn Cement Limited, specializing in cement manufacturing. Delkor’s filter will provide the Woodman Point facility with the ability to remove salts from the sand, that were previously creating problems in their down stream processing.
Delkor is providing polypropylene vacuum boxes for this application as this design provides both high corrosion resistance and erosion resistance. The filter has both high and low vacuum pressure sectionals, increasing vacuum efficiency. This innovative design produces a high vacuum in the wetted dewatering section and wash zones, whilst a vacuum fan produces an economically lower vacuum across the drying zone of the filter.
The filter is to be driven by a 75kW motor and is expected to be fed at 450 dry tonnes per hour, containing 38,000ppm total dissolved salts. Passing through the filters three stage counter current arrangement, the sand will be discharged at 2000ppm total dissolved salts..
I got saw this yesterday looking through a mining mag. Don't know if we will notice any difference as the public? Better filtration is a good thing for everyone.

Makes you wonder what they need to filter out today that they didn't filter out yesterday.

Won't make a difference to Woodies unless they plan to put the waste back into the water, but I haven't seen anything yet to idicate that. The mirky water at woodies is caused by the dumping of the sand from the boats and pumping it into the plant. The waste then gets dumped next to the building (that's what all those shells are).
