Municipal Wastewater Treatment

Packaged wastewater treatment plants are ideal for municipal wastewater treatment as they offer a compact, efficient, and cost-effective solution for the treatment of sewage. These plants use advanced technologies like MBRs (Membrane Bioreactors), MBBRs (Moving Bed Biofilm Reactors), and DAFs (Dissolved Air Flotation) to effectively remove contaminants from wastewater. MBRs use a combination of physical filtration and biological processes to remove impurities, while MBBRs and DAFs use a biological process and physical separation respectively to treat wastewater. These technologies ensure high-quality treated water, meeting discharge standards, and making packaged wastewater plants an attractive option for municipal wastewater treatment.


WSI is a leader in Moving Bed Biofilm Reactor (MBBR) technology, Dissolved Air Flotation (DAF) and Aerobic Sludge Digestion. Our plants require minimum operational oversight that will meet or exceed strict discharge standards.

Ensuring Compliance: The Role of Packaged Wastewater Treatment Plants

Packaged wastewater treatment plants play a significant role in ensuring compliance with environmental regulations. They use advanced technologies like MBRs, MBBRs, and DAFs to treat wastewater to meet the discharge standards set by regulatory bodies. The treated water produced by these plants is of high quality, reducing the risk of environmental pollution. Furthermore, these plants are designed to be easy to operate and maintain, reducing the likelihood of human error and ensuring consistent compliance with regulations. The use of packaged wastewater treatment plants helps municipalities meet their environmental obligations, protects public health, and ensures the sustainability of local waterways. Additionally, the compact and efficient design of these plants reduces the land requirements, making them an attractive option for communities with limited space. Overall, packaged wastewater treatment plants provide an effective solution for ensuring compliance with environmental regulations and protecting the environment.

The Benefits of Installing a Packaged Wastewater Treatment Plant

  1. Space-saving: Packaged wastewater treatment plants are compact and require minimal space compared to traditional wastewater treatment facilities.

  2. Cost-effective: Packaged plants are often more affordable than building a custom treatment facility and can save money in construction and maintenance costs.

  3. Easy installation: Packaged plants are designed to be easy to install and can be up and running quickly, reducing the amount of time and resources required for a traditional build.

  4. Low maintenance: Packaged plants are designed to be low maintenance, reducing the need for frequent repairs and the associated costs.

  5. Portable: Packaged plants can be easily relocated if necessary, making them a good choice for temporary or temporary-to-permanent treatment solutions.

  6. Environmentally friendly: Packaged plants use advanced treatment technologies to reduce the environmental impact of wastewater treatment, making them a more sustainable option.
