Treatment of Gray Water in College of Engineering Vadakara

Abstract

In recent years, our state had a tough time dealing with issues related to water scarcity and the disposal of sewage, which is a major problem around the globe. One of the principal causes is an increase in the level of pollutants and heterogeneity of sewage water. Various sources of sewage generation are residential societies, industrial areas, commercial zones, etc. Each zone contains a specific composition of sewage. Instead of source segregation, we still follow the traditional way of mixing everything and sending it to the respective sewage treatment plants, which results in lower efficiency of the treatment process, leading to pollution of water bodies and high waste generation. Disposal itself is a problem due to a shortage of land. To avoid this, the decentralization of sewage treatment must be encouraged. Phytorid technology is such a type of system, which reduces the impact of sewage and converts into useful water for gardening and irrigation purposes. Phytorid works on the natural capacity of plants to utilize nutrients from wastewater from various sources. Considering the rising pollution of water bodies due to the discharge of waste in them, it is necessary to initiate alternative thinking as the conventional method through sewage treatment plant (STP), have had limited success. To study the characteristics of phytorid bed, we constructed a phytorid prototype in our college campus.
