This Article explains how to create and what are the factors needs to be considered in effluent treatment plant design process. Read More about? Benefits of Effluent Treatment Plant All manufacturing companies face strict regulations on waste and discharge.

Non-Compliance can lead to fine and operations interference from pollution control board. Wastewater treatment plant can be beneficial for: • Stay in compliance • Eliminate municipal fine • Reduce supply cost by recovering production materials out of the waste stream for recycle • eliminate extra water usage during processing • Reduce hauling and off-site treatment cost Wastewater treatment plant design is primary process in which untreated waste water is analysed and based on requirement of uses of treated effluent plant is designed. Also design of effluent treatment plan is highly site and industry specific. Design of effluent treatment plant is to treat non-hazardous industrial waste water and should focus on cost-effective, minimal maintenance and requires minimal manpower etc. Also these plants should include processes such as pH change, aerated lagoon, polishing/infiltration ponds and sedimentation/facultative basins etc. Design of Effluent treatment Plant As specified above design of effluent treatment plant is highly depends on industry and site. Major points taken into consideration while designing effluent treatment plants are characteristics of site and wastewater.

Untreated effluent standards and treated effluent standards are also taken into consideration in process of wastewater treatment plant design. Also now coming to selection treatment process, it involves consideration f other multiple factors, Such as treatment efficiency, cost and reliability. Characteristic of Site in ETP Design Characteristic of site like soils, topology, geology, hydrology, climate and land use are taken into consideration while designing ETP. Knowledge of Depth of rock layer and topography (it’s the way where height and depth of land shown in green and yellow Color in map) also helps in designing of ETP for using gravity flow and burial of pipes which are most necessary. Soil thickness, its content, its characteristic, organic, inorganic matter and permeability (capacity of holding water) are also taken into consideration in ETP design Process. ETP plant may affect land used in ETP construction.

Also precipitation is considered when infiltration is problem and evapotranspiration used when wastewater treatment includes process of evaporation. Characteristic of Wastewater in ETP Design Characteristic of wastewater must be taken into consideration in terms of physical, chemical and biological characteristic. Size of effluent treatment plant i.e.

ETP is depends upon its flow (measured in m 3 / day. Flow of wastewater should be estimated correctly considering all possible reasons otherwise they will affect hydraulic computations, channels and pipes. Also if there is need to construct equalization pond due to temporary large flow (eg rainfall etc.) to maintain constant flow downstream treatment process. Equalization ponds also helps to reduce toxicity of wastewater. Physical Characteristic of Wastewater include PH, Colour, odour, temperature.

Suspended solids, grease, oil indicate highly polluted wastewater with very low turbidity. Presence of these matters indicate that need of pre-treatment before releasing to environment. Temperature is also major factor because higher the temperature higher the reaction rate. Chemical characteristic of wastewater includes organic, inorganic in solutions and gases. Biological Oxygen demand (BOD) is indicator of amount of biological substances (proteins, fats, etc.) present in effluent. Comparison of BOD for untreated and treated gives idea about efficiency of Effluent treatment plant.
