Study on Use of Waste Water in Hydroponic System Instead of Nutrient Solution

Abstract

Abstract: Today, soil based agriculture is facing some major problem also decreasing per capita land availability. As well as water scarcity is major problem due to amount of water required is variable likewise, the water used for agriculture, industrial and domestic use. The earth covers 97.2% saline water and 2.8% fresh water only, the world population is increased day by day due to explosion of population we required more water supply and land for food requirement, therefore we need to recycle and reuse of waste water produce in our country. In sufficient capacity of waste water treatment and increasing sewage generation pose big question of disposal of waste water. In a India due to lack of sewage treatment plant, the 70% waste water diverted without treatment to the river and natural stream it create human health hazards. The soil degradation problem occurs while using the land for agriculture. Hydroponic technique is derived for facing those problems. It is a soil less culture in artificial environment in which plants are grown in nutrient solution without soil. The domestic sewage is also contain properties of nutrient solution, therefore it is possible to use sewage water in hydroponic system to grow plants, sewage water moving through plant root will be utilized this plant. It possible to reduce waste water parameter in hydroponic technique, the reduction in COD and BOD up to 50% is obtained from result.
