Water management solutions are increasingly in demand across the modern aggregates production world, with water being a valuable global resource. MWS Equipment has listened to their customers, particularly in regions where it can be difficult and, in some cases, impossible to find the water required to supply an aggregate processing plant. MWS has used its high-level expertise within this industry to design a range of thickener systems that complements the current range of wet processing equipment.
The primary goal of the Hydropure thickener is to recycle as much water as possible at the point of use ready for feeding back to the wash plant. The MWS Equipment range of thickeners comes in a variety of diameters of 6, 8, 10, and 12 metres. They are designed to handle various flow rates from 180 to 650 m³/hr of slurry and process up to 40 tph of solids.
A well-designed and installed thickener system can recycle up to 90% of the original feed water supplied to the plant. This greatly reduces the amount of “fresh” water which is required. The use also vastly reduces the overall footprint of a plant as it reduces the need for large surface area settling ponds and the costs associated with operating such ponds.
Smarter Operation Unit
The cyclone overflow (waste slurry) from the wash plant is directed to the Hydropure thickener where an anti-turbulence feed chamber adds a small amount of flocculant to the waste stream. This flocculant which is prepared in a dedicated makeup station is used to combine the small particles together into larger sizes. These larger size particles then sink to the bottom of the Hydropure Thickener, allowing the clean water to flow over the weir into the clarified water tank, for direct reuse within the wash plant.
The particles which settle in the tank are collected in a lower cone section where they can be pumped from the thickener. The Hydropure is fitted with a centrifugal pump which is used to pump this waste sludge out of the thickener. This can either be to a settling pond or sludge holding tank for further processing by a filter press or similar.
The system is controlled from either a dedicated standalone PLC system or it can be combined into the controls of the MWS Equipment wash plant.
As a result, customers enjoy the flexibility to choose the best filtration technology for their production environment, along with being able to integrate the Hydropure into existing equipment.
