Grey Water Recycle

Grey water is defined as water from baths, showers, hand basins and clothes washing machines or the laundry. Any water from any other source ( toilet water, and from kitchen and bidet’s) is considered black water, and must be allowed to proceed to the septic tank or sewer, and be treated by some sort of sewerage treatment works.

A bath uses 80 litres and a shower 60 litres of water. When used, that water is called grey water. You pay for it, and then it all goes down the drain. Our STOREMORE filtration-bed system can recycle this water to immediately irrigate your garden, saving you a substantial portion of your water bill.

Grey water is the solution to the problems relating to demand and supply management of water worldwide.

Grey water is the biggest contributor to wastage of water. A best 33% of water consumed in the home is normally thrown away and at worst perhaps 50%. Grey water is very useful for two purposes, re-used for toilet flushing or for irrigation purposes.

There are several rules for the re-use of grey water and these are:

1. Never store grey water: This is the first law and may not be changed: the problem is that grey water has temperature and food value for anaerobic bacteria to breed and produce methane and hydrogen sulphide, the stuff that smells so badly

2. Do not let grey water pool: Sending water to flood irrigate gardens on a regular basis means that a bacteria will clog the soil, preventing penetration of water into the soil, that needs to be overcome by some sort of cultivation.

3. Grey water is dirty water and may not be fed into any irrigation system directly, this includes drip irrigation, because all irrigation systems require clean water and high pressure.

We have the solution to deal with Grey water effectively with our unique STOREMORE modular tanks

Methodology

In STOREMORE filtration bed system, the Grey water is first sent in to a porous special tank built to any size and the collected water is allowed to pass through various grades of filter medias (from large pebbles to small pebble, chips, activated carbon, and sand). Finally the filtered water passes through the nonwoven filter membrane (Geo textile) and is collected in the final tank which is pumped out and used.

Special microbial culture with enzymes for active multiplication is introduced along with the filter medias for even development of bio-film

The process of digestion may be aerobic followed by anaerobic, or simply anaerobic, and the filtration removes suspended solids only or both suspended and dissolved solids. The bio film (micro organisms) which develops in the filter medias, digests most of the organic matters.

The final stage of filtration by the geo textile fabric prevents entry of sand or dust to the last tank, so the water is clean for re use. Odour removal is accomplished by chlorination at the final stage.
