Product Description


MBR Membrane Sewage Treatment System
The MBR system, short for Membrane Bio-Reactor, is an emerging technology that combines membrane technology with biochemical reactions in wastewater treatment. The core of the MBR system is an enhanced polyvinylidene fluoride (PVDF) hollow fiber ultrafiltration membrane, which produces high-quality and stable water. It not only avoids the problem of suspended solid leakage that occurs in traditional sedimentation processes but also removes microorganisms such as E. coli and Cryptosporidium. The water produced by the membrane system can be used directly or with a small amount of disinfectant added for non-potable or reclaimed water reuse.
Product Composition
The MBR membrane system mainly consists of membrane modules, membrane frames, membrane tanks, Roots blowers, aeration devices, water production pumps, water storage tanks, sludge return pumps, cleaning systems, and instrument automation control systems.

Product Parameters


Technical Principle: 
Firstly, biodegradable organic pollutants in the water are removed through activated sludge, and then the purified water is separated from the activated sludge using a membrane.
The hollow fiber membrane filaments are tubular with micropores on the walls that can retain activated sludge and most suspended solids, resulting in clear and transparent effluent. To ensure the long-term continuous and stable operation of the membrane, a certain amount of aeration is performed below the membrane. This not only meets the biological oxygen demand but also causes the membrane filaments to vibrate continuously, preventing the attachment of activated sludge on the surface of the membrane and causing fouling.
The MBR process organically combines membrane separation technology from separation engineering with traditional wastewater biological treatment technology. It eliminates the need for a secondary sedimentation tank and significantly improves the efficiency of solid-liquid separation. Additionally, due to the increased concentration of activated sludge in the aeration tank and the presence of specialized bacteria (especially dominant bacterial groups), the rate of biochemical reactions is enhanced. At the same time, by reducing the F/M ratio, the production of excess sludge is reduced (even to zero), thus fundamentally solving many prominent problems associated with traditional activated sludge processes.
Product Features/Advantages:
1. Low pressure with high flux, low energy consumption:
The Witaya MBR membrane product has ultra-high pure water flux and stability, offering high flux under low pressure and capable of long-term stable operation under high pressure.
2. High chemical resistance:
Using new formulations and hydrophilic modification processes, the membrane filaments maintain their hydrophilicity after long-term cleaning with chemicals (acids, bases, NaClO), with almost zero decay in hydrophilicity and good resistance to pollution.
3.High mechanical strength, resistant to peeling and breaking:
Using Witaya's unique high-pressure-resistant skin layer structure control technology; asymmetric gradient sponge body structure with high membrane stiffness; plus root soft gel protection to prevent breakage at the base of the membrane filaments.
4.Good hydrophilicity, resistant to pollution, dry preservation: 
Using fully separated layer chemical crosslinking hydrophilic modification technology, the entire water flow channel of the membrane filaments has complete hydrophilicity, offering high flux, high energy efficiency, and high resistance to pollution compared to similar products on the market. Dry packaging, transportation, and installation are used, eliminating the need for organic solvent replacement, making packaging and storage convenient. The product can be repeatedly immersed in water and dried for use, quickly wetting, with almost no decay in membrane flux.
5.Modular design, simple installation:
The MBR membrane system can be designed in a modular unit manner, facilitating phased reconstruction and expansion for various large water plants or small community water purification equipment. The civil engineering workload can be carried out according to the final design flow, while the number of membrane modules in the membrane system can be increased according to the treatment capacity required at different stages of the wastewater treatment plant.
6.Other features:
The Membrane Bio-Reactor (MBR) has high treatment efficiency, good effluent quality; compact equipment, small footprint; easy to achieve automatic control, simple operation and management.
Due to the efficient solid-liquid separation characteristics of the membrane separation system in the MBR system, it can effectively perform solid-liquid separation, with separation effects far better than traditional sedimentation tanks, producing excellent effluent quality with suspended solids and turbidity close to zero, which can be directly reused, achieving the resource utilization of wastewater.
The efficient interception function of the membrane ensures that microorganisms are completely retained within the reactor, achieving complete separation of the hydraulic retention time (HRT) and sludge age (SRT) in the reactor, making operation control more flexible and stable, overcoming the disadvantages of unstable effluent quality and sludge bulking in traditional processes. 
It can operate stably under high concentrations of activated sludge (5000-10000 mg/L or even higher). The high concentration of activated sludge characteristic in the MBR environment allows wastewater with more organic components to be decomposed in a shorter time or in a smaller space, with faster biochemical reaction rates and strong shock load resistance.
Due to the separation of SRT and HRT, the sludge age is extended, allowing macromolecules and difficult-to-degrade components in the wastewater to have sufficient retention time in the limited volume of the bioreactor, greatly improving the degradation efficiency of refractory organic matter. The reactor operates with high volumetric loading, low sludge loading, and long sludge age, significantly reducing the amount of sludge discharge, and even achieving zero sludge discharge.
The extension of sludge age is conducive to the retention, growth, and reproduction of slow-growing nitrifying bacteria, improving the system's nitrification efficiency and providing certain denitrification and phosphorus removal functions.
Eliminates the need for a secondary sedimentation tank, saving 30~50% of installation space. MBR can also utilize existing facilities for expansion and renovation, reducing the land area occupied by new facilities.
The system uses PLC control, enabling fully automated control for easy operation and management.
