Waste Water Recycling

Effective Water Recycling System for Waste Water.

The Water Recycling System

The waste water from the wash bay is coming together in the wash bay gully and flows from there into a sludge pit. From the sludge pit the water will overflow into the aeration pit, which has about the same size as the sludge pit. In this pit we will place the heavy aeration as well as the grinder pump (this is a submersible pump with knives at the bottom). The heavy aeration has two functions:

a) getting rid of all volatile substances in the water.

b) Saturation with oxygen to avoid any anaerobic condition.

By the grinderpump the wastewater will be transported to our recycling unit.

It will firstly pass the hydrocyclones for filtration. The filtered water (90%) will continue to flow to the bioreactor. The remaining water (10%) with the concentrated dirt will flow back to the sludge pit. The filtration process achieves a value of 5 micron. The remaining water is not wasted, but stays in the process. The concentrated dirt particles will settle down in this sludge pit. The filtered water passes through the bioreactor in which the dissolved substances, like oil and chemicals, will be removed on a biological way, after which the water can be stored for reuse in the wash bay.

The end result will be clean and clear water suitable for reuse in the wash bay, without any negative effect on the washing result compared to using fresh water. The clean water storage should have at least a capacity equal to the average hour consumption of water by the washing machine.

If some local situation with existing pits and / or interceptors deviates from the advised situation as indicated above, details should be send over and we will study them for a full engineering into the most ideal installation based upon the given data.
