Effluent treatment is a process of removing contaminants from wastewater. The whole treatment contains various physical, biological and chemical processes. Its aim is to release safe water to environment so that it cannot harm the environment.

Benefits of Effluent Treatment Plant

In recent times, all manufacturing companies face strict regulations on waste and its unregulated discharge. Non-Compliance to them can lead to fine and operational interference from pollution control board. In addition to that a wastewater treatment plant provides folowing benefits as well :

• Keeps the company in compliance
• Reduces supply cost by recovering production materials out of the waste stream for reuse
• Eliminates extra water usage during processing
• Reduces hauling and off-site treatment cost  

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. Furthermore, an ETP is to treat non-hazardous industrial waste water while being cost-effective, should require minimal maintenance and manpower. The treatment process should be inclusive of pH change, aerated lagoon, polishing/infiltration ponds and sedimentation/facultative basins etc.

The design of effluent treatment plant is often industry specific reason being the difference in inlet parameters. Characteristics of site, required treated effluent standards, trearmennt method used aer some other parameters which play major role in designing..

ETP Design Parameters

Abve mentioned site characteristics include soils, topology, geology, hydrology, climate and land use. 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. Soil thickness, its content, its characteristic, organic, inorganic matter and permeability (capacity of holding water) are to be kept in mind while structural design. Precipitation often plays an important role where infiltration is problem. The role of evapotranspiration becomes imporatant as one of the treatment process uses evaporation.

Apart from above mentioned soil chaaracteristics, physical, chemical and biological characteristic of wastewater need to be kept in mind while deciding methodology. Size of ETP is depends upon its flow Flow of wastewater should be estimated correctly considering all possible reasons otherwise they will affect hydraulic computations, channels and pipes. 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. Chemical characteristic of wastewater includes organic, inorganic in solutions and gases. BOD for untreated and treated gives idea about efficiency of Effluent treatment plant. Chemical oxygen demand (COD) measures biodegradable and non-biodegradable organics. Also ratio between BOD and COD tells much more about ETP health. Removal inorganic substances such as chlorine, nitrogen, heavy metals, cyanides phosphorous and sulphur from effluent should also be kept in mind to avoid excessive algae growth caused by nitrogen and phosphorous.

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 fine
• Eliminate extra water usage during processing by recycling the treated water
• Reduce hauling and off-site treatment cost

Wastewater treatment plant design is primary process in which untreated waste water is analyzed 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 for 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 m3 / 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.

Chemical oxygen demand (COD) measures biodegradable and non-biodegradable organics. Also ratio between BOD and COD tells much more about ETP health.

Removal inorganic substances such as chlorine, nitrogen, heavy metals, cyanides phosphorous and sulphur from effluent is also important because Nitrogen and phosphorus prone to excessive algae growth and harmful heavy metals increase toxicity.

Due to microbiological actions in wastewater treatment methods produces various gases. The type of gases indicate whether aerobic or anaerobic degradation is taking place.
