ENVIRONMENTALLY FRIENDLY WASTE SEPARATOR FOR REMOTE SITES

CST Wastewater Solutions has been selected as a finalist in the environmental excellence category of the national Future of Mining Awards 2019 for its KDS multi-disc roller separator that removes more than 50 per cent of the water from wastewater sludge to provide a 50 per cent reduction in sludge transportation costs from remote and inaccessible sites.

The energy-efficient separator is designed for efficiency, sustainability and conservation of resources in small-to-medium applications, including mining, oil and gas exploration and development camps, where its benefits include consuming little electricity (as little as 0.06kWh) and using no washwater.

The lighter, less sloppy sludge it produces is more easily and hygienically handled on-site and costs less than half to transport away from sensitive areas, because it weighs less than half typical wastewater sludge outputs.

The new skid-mounted version offers users a highly effective plug-and-play solution that can be carried by truck or trailer to remote and environmentally sensitive sites. Measuring only 3.8 x 2m, it features a unique self-cleaning dewatering and conveying system with an oval plate separation and transfer structure that prevents clogging and permits automatic continuous operation handling oily and fibrous materials with ease.

“The technology’s simplicity and low maintenance in operation provides cost savings and well as environmental benefits to Australian companies,” says CST Wastewater Solutions Managing Director Michael Bambridge, whose company has also installed highly successful Smith and Loveless FAST waste water treatment plants on remote mining locations.

The two-stage system uses a combination of coarse and fine screening and advanced dry compaction technology to produce a more hygienic and compact output that is easy to handle and transport. The system is compact and more economical, using less energy and minimal water compared to alternative systems.

“This simple-to-maintain separator offers a high throughput within a small body, with the smallest model being just under 350mm wide and weighing 50 kg,” says Bambridge. “The compact rotational oval plate structure achieves high transportation and separation efficiencies, while the simplicity of the machine’s overall structure offers low maintenance, achieving cost and OH&S benefits through less handling being required to clear hazardous materials.

“The KDS separator uses a fraction of the power of a centrifuge and no water usage during operation, unlike a belt press or a screw press. For a relatively low investment cost, it offers a high performance alternative to sludge drying beds and geobags often used on remote resources sites for dewatering waste sludges.”

Used for thickening dissolved air flotation sludge – a very common application throughout wastewater operations – it achieves solids capture of 97 per cent thickened sludge at a dryness of 17 per cent. Waste activated sludge dryness levels are typically 15-25 per cent.

It is designed for use in applications including food-processing waste, raw wastewater (primary screening) sewage treatment and sludge to landfill. It can also be used to process barrel polishing water, water-based paint wastewater, grease trap waste, dyeing wastewater, waste oil and plastic recycling.
