Containerized Wastewater Treatment Plants

Containerized Wastewater Treatment Plants

In today’s rapidly urbanizing world, the demand for efficient wastewater treatment solutions is more critical than ever before. Containerized Wastewater Treatment Plants represent a significant leap forward in sustainable water management. Their modular design, cost-effectiveness, and environmental benefits make them a compelling choice for a wide range of applications. This article explores the emergence and benefits of Containerized Wastewater Treatment Plants (CWTPs) as a revolutionary approach to sustainable water management.

What are Containerized Wastewater Treatment Plants?

Containerized Wastewater Treatment Plants are compact, modular systems designed to treat wastewater efficiently. They are housed in standard shipping containers, making them easily transportable and customizable to meet specific needs. They comprise primary, secondary, and tertiary treatment units. These include sedimentation tanks, biological reactors, membrane filtration systems, and disinfection units.

key features of Containerized Sewage Treatment Plants

Compact Design

The treatment components (such as reactors, filters, pumps, and control systems) are all housed within a standard shipping container. This design allows for a smaller footprint compared to traditional wastewater treatment facilities.


Containerized plants are often modular, meaning they can be scaled up by adding more containers if the treatment capacity needs to be increased.


Being housed in shipping containers, these treatment plants can be easily transported by road, rail, or sea. This makes them suitable for temporary or remote locations, construction sites, disaster relief efforts, and military installations.


The treatment process within the container can be customized based on the specific requirements of the site and the characteristics of the wastewater being treated.

Treatment Processes

Containerized sewage treatment plants typically utilize a combination of physical, chemical, and biological processes to remove contaminants and pathogens from the wastewater. Common processes may include screening, sedimentation, aeration, biological digestion, and disinfection.

Quick Installation

Since much of the treatment process is pre-engineered and pre-fabricated, installation times are generally shorter compared to conventional treatment plants.

How Containerized STPs Treat Wastewater?

Containerized Sewage Treatment Plants (STPs) are versatile solutions for treating wastewater. They come in two sizes: small-scale for temporary or mobile needs, and large-scale for bigger operations. Here’s how they work:

1. Primary Treatment: Screening and Removal In the first step, coarse materials and solids are removed using a sieving screw. Grease and sand are separated in compact units. The waste is collected in holding tanks for proper disposal. In smaller systems, this step happens in a pre-treatment tank. The leftover sludge undergoes further treatment.

2. Biological Treatment: Converting Contaminants Microorganisms work their magic, transforming dissolved contaminants into sludge and gases. The method used depends on the type and concentration of the wastewater. Everything needed for this process is neatly housed inside the container.

3. Effluent Clarification: Getting it Crystal Clear Effluent, or treated water, goes through lamella separators built into the container. This ensures a final round of thorough clarification before the water is discharged.

4. Tertiary Treatment: Meeting Strict Standards If there are strict discharge limits, additional modules can be integrated. These include chemical dosing, phosphorous reduction, and disinfection. You have options like chlorination, ozonation, or UV irradiation for disinfection.

Applications for Containerized Sewage Treatment

Containerized sewage treatment finds its application in various settings:

  • Mobile worker camps in industries such as oil and gas.
  • Temporary industrial sites.
  • Construction sites with spatial constraints as containers are stackable.
  • Temporary treatment setups.
  • Municipal wastewater treatment, both for permanent and temporary needs.
  • Refugee camps.
  • Military camps.
  • Offshore facilities.
