Embodiment

[0072] A family house located in the Jewish desert (central Israel) is equipped with a gray water recovery and purification system according to the invention. Four cubic rigid plastic containers were used as two wetland units and sinks, each approximately 600 liters and without lids. Two connected containers used as sinks are located in the garden, approximately 3 meters below the level of the family house; the open upper surface of the cubic container is covered by a plastic mosquito net. The tank is provided with a pipe outlet through which the circulating water is pumped from the bottom of the tank and a further pipe outlet through which the water is pumped to irrigate the garden.

[0073] A third container serving as the first wetland unit is located on top of one of the tank containers. The bottom of the third container is perforated with hundreds of holes, each of which has a diameter of about 1 cm, allowing water to drip through the network into the sink. A fourth con...

Abstract

The present invention provides a system and a method for processing and reusing graywater. At least two vertical flow wetland units are provided, each of which comprising a container filled with at least one granular substrate and at least one species of a hygrophilous plant, and an outlet. At least one of the wetland units is set to an inactive state during a predetermined period of time such that influx of graywater to each of the inactive units is prevented, whereby to regenerate each inactive wetland units. At least one of the wetland units is set to an active state to allow introduced graywater to be purified. Purified graywater is discharged from the outlet of each active unit to a sink. At least a portion of the purified graywater is recirculated to each active wetland units so that a portion of the purified graywater, when desired, is discharged to a domestic site for reuse.

Description

technical field [0001] The present invention relates to a method and system for recycling and purifying most domestic waste water. In particular, a novel system and method for gray water reuse utilizing the principles of vertical flow constructed wetlands is provided. Background technique [0002] As living standards improve and as the world's population increases, the demand for fresh water increases dramatically. Available sources of freshwater are very limited worldwide, and in many cases they are unevenly distributed in space or time. Environmental concerns and soaring water prices are driving the need to reuse as much household wastewater as possible [Rogers P.: Scientific American 299, August 2008, 28-35]. [0003] Current methods of reusing non-potable water require the installation and maintenance of expensive and complex equipment, and require large amounts of energy. However, an inexpensive and technically simple solution to the problem of reusing domestic water...
