the water used to wash automobiles. It is “gray” wastewater and comes from salons for hair and nails, restaurants, repair garages, and laundromats.
The other is “black” wastewater that results from unsanitary bathroom situations. This is treated differently from “gray” wastewater and goes into a separate tank. It is constructed using special steel and glass which has been bonded to it to ensure that it doesn’t cause corrosion.
How is wastewater treated
Purifying wastewater for reuse embraces biochemical, physical as well as filtering. Solids, sands or sludge is removed. After the water has been clean, whether biologically or chemically then it’s filtered one more and is then deemed suitable for reuse.
Municipal wastewater storage tanks are large. They are usually above ground and have pumps, just like the others water tanks. They’re constructed of materials that won’t disintegrate under adverse conditions. This is why Mr. Woodward’s explanations for water tanks pertain to the issue of wastewater.
