The role of evapotranspiration becomes imporatant as one of the treatment process uses evaporation.Īpart from above mentioned soil chaaracteristics, physical, chemical and biological characteristic of wastewater need to be kept in mind while deciding methodology. Precipitation often plays an important role where infiltration is problem. Soil thickness, its content, its characteristic, organic, inorganic matter and permeability (capacity of holding water) are to be kept in mind while structural design. Knowledge of Depth of hardstrata and topography (it’s the way where height and depth of land shown in green and yellow Color in map)can be utilised to design gravity flow and burial of pipes which are of utmost importacnce in plumbing of an ETP plant. Characteristics of site, required treated effluent standards, trearmennt method used aer some other parameters which play major role in designing.Ībve mentioned site characteristics include soils, topology, geology, hydrology, climate and land use. The design of effluent treatment plant is often industry specific reason being the difference in inlet parameters. The treatment process should be inclusive of pH change, aerated lagoon, polishing/infiltration ponds and sedimentation/facultative basins etc. Furthermore, an ETP is to treat non-hazardous industrial waste water while being cost-effective, should require minimal maintenance and manpower. Wastewater treatment plant design is primary process in which untreated waste water is analyzed and based on requirement of uses treated effluent plant is designed. Reduces hauling and off-site treatment cost.Eliminates extra water usage during processing.Reduces supply cost by recovering production materials out of the waste stream for reuse.In addition to that a wastewater treatment plant provides folowing benefits as well : Non-Compliance to them can lead to fine and operational interference from pollution control board. In recent times, all manufacturing companies face strict regulations on waste and its unregulated discharge. Its aim is to release safe water to environment so that it cannot harm the environment. The whole treatment contains various physical, biological and chemical processes. Effluent treatment is a process of removing contaminants from wastewater.
