Effect Of Grey Water Use On Soil Chemical Properties, And Spinach’s Product

Abstract

Greywater is a big source of water because it is a big part of home waste water, and its quality consider better than  black water, so its treatment and reuse in agricultrual purposes contribute in reduse of fresh water demand; the study was done in Alnashabiah research  station with 2 years of duration, starting in 2011untel 2015 with the spinach crop, and aimed to study the effect of using graywater on the soil chemical properties and yield. Statistic design of the study is (full random sectors) and consists of two treatments for quality of water (freshwater ,treatment greywater) each treatment includes three replications (2x1 m) and irrigated by surface method of irrigation with same normal of water. The most important results acheved in the study were: greywater can be used safly on cocked vegetables and fruitful trees irrigation, comparing with the Syrian Standrats  N\2752\ as the filtration process helped in redusing the load of organic substances and consequatly the quantity of microbs particularly the Colonic bacteria will be decreased in the water, and the chemical soil properties, irrigated with the greywater, had not been effected during the period of the study, The BOD values for gray water decreased after treatment, and untreated gray water content from organic carbon (TOC) decreased from 60 mg / L to 15 mg / L in treated gray water
