Name of Applicants Samantha Abeysingha Gunawardena Anusha Darshani Guruge Actual Inventors Samantha Abeysingha Gunawardena Anusha Darshani Guruge Name of Invention Household waste water screening diversion method apparatus capable of separating mostly polluted water from less polluted water using electrical conductivity as the screening method.
The following statement is a full description of this invention, including the best method of performing it known to me 1. HOUSEHOLD WASTE WATER SCREENING DIVERSION METHOD APPARATUS CAPABLE OF SEPARATING MOSTLY POLLUTED WATER FROM 00 0LESS POLLUTED WATER USING ELECTRICAL CONDUCTIVITY AS THE O O SCREENING METHOD.
SUsed water from household Showers, Baths, Spas, Hand basins, Laundry troughs appliances t such as washing machines (called Grey water from herein) is normally discharged in to sewage systems.
Water conservation and reuse is becoming increasingly important as finite water resources continuing to diminish.
0 Household waste water screening diversion method apparatus (called Invention from 0 herein) is capable of detecting better quality water in a waste water system divert for recycling 00 purposes* such as garden irrigation.
0 Grey water contains a wide variety of chemicals originating from detergents. Ability to recycle grey water is hindered by high concentration of chemicals. Grey water can be used for watering gardens lawns under rules set by local government authorities.
Although, the use of Grey water is permitted by local government authorities, long term use in the form as it comes from household sewer lines cause soil deterioration contamination due to introduction of undesirable salts chemicals to soil system. This invention helps separate Grey water containing high levels of undesirable salts and chemicals or mostly polluted waste water to an acceptable level of accuracy so that less polluted waste water can be used for recycling purposes In a domestic situation, for an example, waste water from laundry washing cycle and soapy water from a shower (high contaminants) could be separated out with reasonable degree of accuracy directed in to sewer while rinse cycle from the laundry non soapy water from the shower (low contaminants) could be directed to a tank for garden irrigation using the Invention.
At present, there is no practical method of separating good quality Grey Water from the rest, in a household waste water system.
Existing Grey water reuse systems broadly fall in to two categories.
1. Collection systems that collect all the grey water for garden irrigation regardless of its quality. Long term use of these systems is highly damaging to the environment.
2. Purification systems that purify grey water using chemical processes prior to garden irrigation.
The present invention belongs to category 1 systems Recycling purposes Reuse or further Ireulmeni 2007903534 Complete Specification.pdf Drawing 2007903534-01 Figure 1 shows a typical category 1 prior art system in current use.
00 o This system is capable of diverting all of the Grey water in to irrigation regardless of the degree Cl of contaminants present in the water.
This system consists of a tank 1 which holds grey water prior to irrigation. Grey water enters the system trough the inlet 7. A manual diversion valve 10 can be set to let through or bypass the Grey water into the tank. Grey water enters the tank via pipe 11 which has a built in sediment filter. A submersible pump 5 is provided for pumping Grey water out of the tank to an irrigation field via outlet connection 8. In the event of pump malfunction, a bypass siphon overflow line 12 is provided for fail safe operation. Outlet 6 is provided for Grey water overflow to household tfl sewer system. Pump is activated via a fixed level probe 4. Pump operates only when the tank is o full or based on a 24 hour timer 2. Pump electrical contactors are housed in level probe box 9.
Pump electrical terminals 9 provide power supply. In the event of low water level in the tank, 00 integral safety cutoff in pump 5 stop the pump.
The above described prior art system has significant long term environmental implications when used for household irrigation. These systems divert all of the water and make no effort to assess the water quality prior to diversion.
