Where a washing plant for sand & aggregates is in operation wastewater is traditionally sent to settling ponds or lagoons.
However, by introducing the AquaCycle thickener you can:
Where there is an issue with water availability that means a wet processing plant is not possible, introducing our AquaCycle thickener technology can allow your plans for a new plant to proceed as a result of the significant reduction in the volume of fresh water required to feed your washing plant.
The basic operation of the AquaCycle thickener is to separate the suspended solids from your hydrocyclone overflow. This is assisted with the addition of a flocculent. This causes the minus 63 micron / 200 mesh particles to form a chain and sink to the bottom of the AquaCycle thickener tank while the clean water overflows a peripheral weir and is recirculated to your washing plant.
The settled sludge is then pumped away from the AquaCycle thickener to an on-site storage area. It is possible to eliminate the requirement for settling ponds through the introduction of Filter Press technology which accepts the settled sludge from the AquaCycle thickener and presses it to a dry filter cake with +80% dry solids content.
