The water recycler is the first stage of water recycling in the sand, glass, iron and mineral industries. Using gravity, this device performs solid and liquid separation operations by sedimentation method and uses polyelectrolyte materials to accelerate this. The use of this device reduces water costs, related repairs and space required for the wastewater pool and minimizes the use of non-returnable natural resources and 90% of the water used in the washing system is recycled. Depending on the volume of water in need of recycling the dimensions of the thickener can differ in design and manufacturing.
