Compact Modular MBR Sewage Treatment System

When selecting a wastewater treatment solution for industrial and commercial projects, facility owners and contractors commonly face the same set of challenges: extensive on-site civil construction, limited available footprint, high labor and maintenance costs, fluctuating influent quality, and increasingly strict local discharge limits. Our packaged wastewater treatment plant is engineered to solve every one of these pain points in a single, factory-built, plug-and-play system.

Designed as an integrated prefabricated modular unit, this compact wastewater treatment system eliminates complex on-site civil works, minimizes installation space, and delivers flexible, stable purification performance. It is one of the most cost-effective solutions available for small and medium-scale industrial wastewater treatment, domestic sewage treatment, and decentralized water-reuse projects worldwide.

How It Works — Advanced MBR Technology

At the heart of the system is the Membrane Bioreactor (MBR) process, an advanced technology that combines membrane separation with biological treatment. Unlike conventional activated sludge systems that rely on gravity settling in a secondary clarifier, MBR replaces the clarifier and normal filter unit with a hollow-fiber membrane module. This delivers exceptional solid-liquid separation, reducing suspended solids (SS) and turbidity in the effluent to near-zero levels.

The treatment flow typically begins with mechanical bar screening to remove large debris, followed by an equalization tank that balances hydraulic and organic load fluctuations. Wastewater then enters an anoxic/anaerobic zone for denitrification before flowing into the membrane bioreactor tank, where microorganisms break down organic pollutants. Finally, the hollow-fiber membrane module filters out bacteria, suspended particles, and impurities, producing clarified effluent that is stable enough for direct discharge or reuse without tertiary treatment.

What is the MBR?

Membrane Bioreactor (MBR) is a kind of advanced technology developed since theend of 20th century which realized the efficient combination of membrane separationtechnology with biological technology. The membrane separation technology replac-es the traditional active sludge method and the normal filter unit, its zstrong separa-tion ability can make the SS turbidity near to be zeroHydraulic retention time (HRT) sludge age (SRT) s completely separated, the outletwater is good and stable in quality, it can be reused without the third level treatment.Due to the high security and economic and effective water, it greatly expands thescope of application of waste water recycling

Flexible Process Configurations for Every Application

Unlike conventional split-type sewage treatment equipment with a single process and rigid structure, our packaged plant supports flexible combinations of DAF (Dissolved Air Flotation), MBR (Membrane Bioreactor), MBBR (Moving Bed Biofilm Reactor), SBR (Sequencing Batch Reactor), and AO (Anoxic-Oxic / Anaerobic-Oxic) processes. The process train is professionally customized according to your actual wastewater composition, design flow rate, and local discharge requirements, ensuring reliable compliance from day one.

Key Features and Benefits

Superior Treatment Performance The NL-series immersed hollow-fiber membrane module is specially developed for high-efficiency solid-liquid separation. Its high internal porosity and large specific surface area support robust microbial attachment, strong adsorption capacity, and efficient removal of COD, BOD, ammonia nitrogen (NH3-N), suspended solids, oil, grease, and phosphorus.

Compact, Modular, Plug-and-Play Design The fully integrated, prefabricated structure arrives ready for connection. It significantly shortens installation and commissioning time, eliminates expensive civil construction, and requires minimal footprint. Future capacity expansion or system relocation is straightforward, protecting your long-term capital investment.

Easy, Unattended Operation A fully automatic PLC intelligent control system enables 24-hour unattended operation with simple one-key start. This reduces dependence on specialized operators and cuts ongoing labor costs.

Low Operating and Maintenance Costs The membrane module is engineered to resist clogging and does not require frequent backwashing or backflow. Combined with optimized aeration and pumping design, the system delivers lower energy consumption and reduced downtime compared with traditional wastewater treatment plants.

Durable, Corrosion-Resistant Construction The whole machine is manufactured from high-quality carbon steel or stainless steel and finished with world-famous anti-corrosion coatings suitable for harsh outdoor and factory operating environments worldwide.

Stable Effluent and Regulatory Compliance The system consistently produces effluent that meets or exceeds local environmental discharge standards. With CE, ISO 9001, SGS, SABER, and COC certifications, the plant helps customers pass local environmental assessments and customs clearance while eliminating the risk of production shutdowns caused by non-compliant discharge.

Typical Applications

This packaged modular wastewater treatment system is widely used across a broad range of sectors, including:

• Industrial wastewater from food processing, textile dyeing, chemical manufacturing, electroplating, and slaughterhouse operations

• Domestic sewage treatment for factory dormitories, residential communities, schools, hotels, and commercial parks

• Temporary construction site wastewater

• Decentralized wastewater treatment projects in remote or rural areas

• Water-reuse schemes for irrigation, cooling, and industrial process water

We provide customized system designs based on on-site wastewater characteristics and specific project requirements, ensuring reliable treatment performance and full compliance with local discharge standards.
