ROLE OF SOIL ORGANIC MATTER IN PLANT GROWTH FOR HORIZONTAL FLOW SUBSURFACE CONSTRUCTED WETLANDS FOR WASTE WATER TREATMENT

ARVIND KUMAR SWARNAKAR AND SAMIR BAJPAI

Abstract

In the Horizontal Flow Subsurface Constructed Wetland (HFSCWs), wastewater flows through the substratum, which may comprise of various types of filter media such as soil, sand and aggregate. This filter media provides root zone for the vegetation used in HFSCWs. Analysis of Organic Matter (OM) in filter media is necessary part for the HFSCWs and requires regular measurement as a crucial indicator of the substrata (soil) health. The Soil Organic Carbon (SOC) improves the aeration, water filtration and water availability for the plant growth. Although organic, matter parameters Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are reduced by Constructed wetland. In the present paper, importance of the filter media and their organic matter are discussed. Various types of locally available soils such as entisol, insepti soils, alfisoles and vertisoles were collected for the analysis. The soil samples compare with the size and types of gravel. Additionally, one of the industrial slag sample is also analyzed for the comparison study.
