Choosing the Right Industrial Sewage Treatment System for Your Business

Industrial Sewage Treatment System

In this rapidly evolving world, where environmental sustainability is of utmost importance, Industries need to prioritize effective methods for sustainability. Here, industrial sewage and wastewater is a big matter of concern. In this blog, we will guide businesses in selecting the right industrial sewage treatment system, taking into account various factors and requirements.

What is STP? (Sewage treatment Plant)

Sewage treatment Plant is a type of wastewater treatment unit which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application.

After answering the question what is STP? It is crucial to evaluate your business’s specific sewage treatment requirements. Understanding the volume and composition of wastewater generated by your industrial processes is essential in determining the ideal treatment system. Additionally, being aware of discharge regulations in your region will help you make informed decisions.

Once you have assessed your specific requirements, with a keen understanding about importance of sewage water treatment plants, you can consider several industrial sewage treatment systems:

 – Physical Treatment Systems: These rely on physical processes such as sedimentation, filtration, or flotation.

Chemical Treatment Systems: Involve the addition of specific chemicals or coagulants to aid in the removal of contaminants.

Biological Treatment Systems: Processes like activated sludge, trickling filters, or sequencing batch reactors are commonly used in these systems.

Factors to Consider When Choosing the Right Industrial Sewage Treatment System:

1. Understanding the Effluent Composition

Conducting a comprehensive analysis of the effluent will help you identify the types and concentrations of pollutants present. This information will guide you in selecting a treatment system capable of effectively removing or treating these specific contaminants.

2. Compliance with Regulations

Compliance with regulatory standards is non-negotiable for businesses when it comes to wastewater treatment. Ensure the treatment system you choose meets or exceeds the local, national, and international regulations regarding effluent discharge.

3. Treatment Efficiency

Assess how well the system can remove pollutants and treat the wastewater to the desired quality. Look for treatment options that have a proven track record of achieving high removal rates.

4. Scalability and Flexibility

As your business grows, so will your wastewater generation. It is essential to choose a treatment system that can scale up or down as per your needs.

5. Lifecycle Costs

The costs associated with the treatment system extend beyond its initial installation. Evaluate the long-term operational and maintenance costs, including energy consumption, chemical usage, sludge disposal, and regular servicing. 

6. Technology Selection

There are various technologies available for industrial sewage treatment, each with its pros and cons. Research and explore different treatment options to determine its suitability for your business.

7. Expert Consultation

Seeking expert consultation and advice can be immensely beneficial when choosing the right sewage treatment system for your business. Consultants can assess your requirements, evaluate treatment options, and help you make an informed decision.

Types of Industrial Sewage Treatment Methods

1. Activated Sludge System

The activated sludge system is a widely used biological treatment process that involves the growth of microorganisms to break down organic matter in wastewater. It relies on aerobic conditions and the continuous recycling of biomass to maintain stable treatment performance.

2. Extended Aeration System

The extended aeration system is another biological treatment method that utilizes aeration to promote the growth of microorganisms that consume organic pollutants. This system operates with longer aeration times and lower sludge production, making it suitable for small to medium-sized industries.

3. Trickling Filter System

The trickling filter system utilizes a bed of inert material such as rocks or plastic media to support the growth of microorganisms. Wastewater is passed over the filter, allowing the microorganisms to break down organic matter through biological processes. This system is commonly used in industries with high organic loadings.

4. Sequencing Batch Reactor

Sequencing batch reactors (SBRs) offer a flexible and efficient way to treat wastewater. In this system, wastewater is treated in batches, with various treatment stages including filling, aeration, settling, and decanting occurring in a single tank. SBRs are known for their robustness and suitability for variable flow and load conditions.

5. Membrane Bioreactor

A membrane bioreactor (MBR) combines biological treatment with membrane filtration to achieve high-quality effluent. This system uses fine membranes to separate suspended solids and microorganisms from the treated water, resulting in superior effluent quality. MBRs are compact, have a smaller footprint, and are effective in treating industrial wastewater with high levels of contaminants.

6. Chemical Coagulation and Flocculation

Chemical coagulation and flocculation involve adding specific chemicals to wastewater to destabilize contaminants and form larger particles. These particles can then be easily removed through sedimentation or filtration, resulting in clarified water. Chemical treatments are often employed as pre-treatment or in conjunction with other treatment methods.

7. Ultrafiltration & Reverse Osmosis

Ultrafiltration and reverse osmosis are membrane-based treatment processes used to separate dissolved molecules, particles, and salts from wastewater. Ultrafiltration utilizes a porous membrane to filter out suspended solids and macromolecules, while reverse osmosis involves applying pressure to remove dissolved salts and contaminants. These technologies are suitable for industries requiring highly purified water.

8. Electrocoagulation

Electrocoagulation employs an electric current to destabilize and coagulate suspended particles and contaminants in wastewater. It is an effective method for removing heavy metals, oils, emulsified substances, and various organic and inorganic pollutants. Electrocoagulation is considered a versatile and environmentally friendly treatment option.

9. UV Disinfection

UV disinfection uses ultraviolet light to destroy harmful microorganisms present in wastewater, rendering them harmless. This method is commonly employed as a final step in the treatment process to ensure the effluent meets disinfection requirements. UV disinfection is chemical-free, and it does not produce harmful by-products.

10. Ozonation

Ozonation is a powerful oxidation process that involves the use of ozone gas to treat wastewater. Ozone effectively removes organic compounds, colour, odours, and pathogens, making it suitable for a wide range of industrial applications. Ozonation is highly efficient and fast-acting, providing an additional level of treatment beyond conventional methods.
