Process flow diagram of a CETP and its working process and function
In today's world, industries are an essential part of the economy, and they play a vital role in creating employment opportunities and contributing to the country's GDP. However, with the growth of industries, there is an increase in the generation of wastewater, which, if not treated properly, can have severe consequences on the environment and public health. Common Effluent Treatment Plants (CETPs) are an effective solution to this problem.
In this blog, we will discuss the process flow diagram of a CETP and its working process and function in detail.
Process Flow Diagram of a CETP:
The CETP's primary objective is to treat the wastewater generated by multiple industries in a city or town and discharge it into the environment as per the permissible limits. The process flow diagram of a CETP is as follows:
Working Process and Function of a CETP:
The CETP's primary function is to treat the wastewater generated by multiple industries and discharge it into the environment as per the permissible limits. The working process of a CETP is as follows:
- Monitoring: The CETP continuously monitors the quality of the wastewater entering the plant to ensure that it meets the permissible limits. The monitoring process includes the use of various sensors and meters to measure the pH level, temperature, and other parameters of the wastewater.
- Pre-Treatment: Before the wastewater enters the treatment process, it undergoes pre-treatment, which includes screening and grit removal. The pre-treatment process removes large solid particles from the wastewater and prepares it for the primary treatment process.
- Primary Treatment: In the primary treatment process, the wastewater undergoes sedimentation, where the suspended solids settle down at the bottom of the sedimentation tank. The clarified wastewater is then passed on to the secondary treatment process.
- Secondary Treatment: The secondary treatment process is a biological process that uses microorganisms to break down the organic matter in the wastewater. The microorganisms convert the organic matter into carbon dioxide and water, which results in a significant reduction in the pollutant load of the wastewater. The secondary treatment process can be done using various methods, such as activated sludge process, sequencing batch reactor, and upflow anaerobic sludge blanket.
- Tertiary Treatment: After the secondary treatment process, the wastewater undergoes tertiary treatment to remove any remaining pollutants. The tertiary treatment process includes the use of filters, coagulants, and disinfectants to treat the wastewater. This process ensures that the treated wastewater meets the permissible limits before discharging it into the environment.
- Discharge: The final stage of the CETP process is the discharge of treated wastewater into the environment. The treated wastewater is discharged into a river, lake, or any other water body as per the permissible limits. The CETP ensures that the discharged water is safe for the environment and public health.
Benefits of CETP:
1. Cost-Effective: CETPs are a cost-effective solution for treating wastewater generated by multiple industries. Instead of each industry setting up its own treatment plant, they can share the cost of setting up and operating a CETP.
2. Environment-Friendly: CETPs help to reduce the pollutant load in the wastewater before discharging it into the environment. This helps to protect the environment and maintain the ecological balance of the water bodies.
3. Compliance with Regulations: CETPs ensure that the treated wastewater meets the permissible limits before discharging it into the environment. This helps industries to comply with the environmental regulations and avoid penalties for non-compliance.
CETPs are an effective solution for treating the wastewater generated by multiple industries in a city or town. The process flow diagram of a CETP includes collection and transfer of wastewater, screening and grit removal, primary treatment, secondary treatment, tertiary treatment, and discharge. The working process of a CETP includes monitoring, pre-treatment, primary treatment, secondary treatment, tertiary treatment, and discharge. CETPs are cost-effective, environment-friendly, and help industries to comply with environmental regulations. By implementing CETPs, we can protect the environment and public health and ensure sustainable development.
