Effect of gasifier effluent on agricultural production and soil

Abstract

Gasifier generates wastewater during cooling and cleaning of producer gas. This wastewater contains harmful chemicals which adversely affect the natural stream if disposed off without treatment. In the present work the effect of gasifier effluent on agricultural soil and vegetable production was studied. Experiments were conducted on seasonal vegetables like radish, spinach and tomato plant. Each plant was irrigated with gasifier wastewater and treated wastewater to study the effects of these waters and compared with control plants which were irrigated by tap water. After irrigation with gasifier wastewater and treated wastewater, different physico-chemical analyses of soil and growth parameters of plant were done. It was found that gasifier wastewater is not suitable for agricultural fields. It inhibits or delay growth of plants. But after suitable treatment, it can be useful for agricultural fields.
