Whether you are replacing an old project or designing a new project, we can provide it for you based on our rich experience. We have professional sales staff to connect with you to solve all your problems from purchasing to using the MBR membrane.
We can provide flat membranes, hollow fiber membranes and sewage treatment components, including sewage treatment solution design and subsequent maintenance guidance
Flat sheet (FS) membranes have planar configuration and are predominantly rectangular. They are designed to be immersed in the membrane tank, and scoured with air to maintain the flow of sludge through the membrane channels
PVDF hollow fiber MBR is made of modified PVDF material, with high flux, good chemical resistance and pollution resistance. The polyester interlayer support net greatly increases the mechanical strength of the membrane silk.
Custom wastewater treatment solutions tailored to your specific needs
Professional installation and commissioning services
Ongoing maintenance support and technical guidance
Comprehensive comparison between Hollow Fiber and Flat Sheet Membrane Bioreactor (MBR) technologies for wastewater treatment applications
Hollow fiber configurations are designed for higher fluxes, operated at lower concentrations, cleaned more often and protected by stricter pre-treatment compared to flat sheet systems. The filterability of activated sludge from municipal MBRs is superior to industrial MBRs and remains independent of membrane configuration.

PVDF's superior oxidation resistance compared to other materials (such as PE) makes it the mainstream material for MBR membranes in sewage treatment and reuse applications.
Backwashing is the most ideal pollution recovery method for the membrane industry. The inability to backwash is the biggest defect of flat membranes, leading to shortened chemical cleaning cycles.
Membrane Bioreactors (MBRs) can be broadly defined as a system that combines wastewater biodegradation with membrane filtration. They have proven to be very effective in removing organic and inorganic pollutants as well as biological entities from wastewater.
There are many types of MBR such as tubular, plate and hollow fiber. Among them, hollow fiber PVDF material has been proven to be the most reasonable in price and good in performance. The membranes used had pore sizes ranging from 0.01 to 0.4 µm.
Good control of biological activity with automatic STP system operation and reduced labor costs
Produces effluent free of bacteria and pathogens with superior water quality
Smaller plant size with lower space requirements due to higher MLSS and short HRT
Capable of handling higher organic loading rates efficiently
Currently, MBR is widely applied to all types of wastewater, including water recycling in buildings, wastewater treatment for small communities, industrial wastewater treatment, landfill leachate treatment, and agricultural wastewater processing.
MBR systems were initially used for municipal wastewater treatment, primarily in the area of water reuse and recycling. Compactness, production of reusable water, and trouble-free operation made the MBR an ideal process for recycling municipal wastewater in water and space limited environments.
High organic loadings and very specific and difficult to treat compounds are two major characteristics of industrial waste streams that render alternative treatment techniques such as the MBR desirable. Since traditionally wastewater with high COD content was treated under anaerobic conditions, initial attempts of MBR applications for industrial wastewater were in the field of anaerobic treatment.
Also effective removal of nitrates, herbicides, pesticides, and endocrine disrupting compounds may be achieved by MBRs.
In addition to municipal and industrial wastewater treatment, MBRs have been utilized in a number of other areas. One such area is the treatment of landfill leachates. Landfill leachates usually contain high concentrations of organic and inorganic compounds.
MBR systems have been successfully utilized with an additional treatment step for inorganics and heavy metal removal, such as Ultra Filtration and reverse osmosis (RO). Several industrial scale plants, combining a MBR, Ultra filtration and a reverse osmosis system, are presently operated.
