Modular Wastewater Treatment Plant
Containerized MBR systems are designed with simplicity, flexibility and durability in mind.
These containerized wastewater treatments plants provide high quality, portable treatment solutions ideal for remote and tight locations. The fully contained systems require minimal site preparation and are manufactured using rugged materials suitable for harsh environments. Once deployed, the systems are extremely low energy and low maintenance, with minimal operator supervision required. The inherently robust design is resistant to shock loading and reduced input conditions.
Advantages:
- Faster project completion time
- Requires very small foot prints which saves on land requirements
- Can be installed in more challenging project sites
- Requires much less civil and peripheral works
- Modular and expandable with zero downtime
- Utilizes most advanced technologies in water treatment
-
Low maintenance and operating costs -
No foul odor and noise

MBR Container System
The integrated MBR plants adopts modular design, which is composed of four units, as shown in the figure below.
Process Route
The process flow of the system, which is mainly composed of pre-treatment unit and MBR integrated equipment. The core technology is the combination of a membrane module and a biochemical reactor.
The wastewater treatment system consists of aerobic tank, anoxic tank and membrane tank.
• Aerobic tank: the organic substants in the sewage will be degraded, absorbed and then decomposed by fully mixing with activated sludge composed of microorganisms. The aerobic bacteria take dissolved oxygen as electron acceptor and carbon source as electron donor for aerobic respiration in the aerobic tank, the final products are mainly carbon dioxide and water. Ammonia nitrogen will change into nitrate nitrogen under nitrite reaction through nitrite and nitric acid bacteria in the aerobic environment.
• Anoxic tank: nitrogen generated by nitrate nitrogen through denitrifying reaction under the action of denitrifying bacteria will be released into the atmosphere. In order to make full use of the carbon source, the Anoxic tank was placed before the aerobic tank, and the effluent of the aerobic tank flow returned to the Anoxic tank for denitrification.
• Membrane tank: hollow fiber membrane module will be installed in the tank, the water will be filtered by the micro pore on the surface of the membrane fiber. In order to prevent the foulling of sludge on
the menbrane surface, there is aeration device at the bottom of the membrane tank. The blower will provide the air to keep the membrane clean.
