The most cutting-edge and effective method for treating wastewater in municipal and industrial settings is the membrane biological reactor (MBR), which combines traditional activated sludge (CAS) with high-efficiency membrane separation technology.The membrane separation activated sludge technique, also known as the membrane bio-reactor, has drawn interest recently as a novel method of recycling water that can save the environment and the planet's finite water supplies. These hollow fiber membranes function as filters to take contaminants out of water or wastewater. They are composed of a cylindrical hollow fiber structure. The large surface area to volume ratio made possible by the hollow fiber design boosts the membrane filtering process' effectiveness. composed of PVDF, or polyvinylidene fluoride.
As a top producer and supplier of MBR membranes, we develop, test, and manufacture these membranes for use in a range of water treatment applications, including membrane bioreactors for the treatment of other wastewater streams and industrial effluent.
In wastewater treatment systems, numerous biological reactors are utilized to recover wastewater for further use in addition to reducing environmental impact through improved wastewater treatment water quality. Worldwide, MBR membrane bioreactors are widely used to recycle wastewater in order to address severe water scarcity. NIHAO, the rapidly developing company in membrane technology, intends to persist in its endeavors within the rapidly growing water recycling industry.
Transport:

The modules need to be shielded from extreme heat, moisture, air pressure, hard impacts, and bumps. Inversion must also be forbidden. The temperature range for the environment must be 0–40°C. Please take your time reading the relevant information before choosing a transport vehicle and lifter. The modules are filled with a unique protective solution that contains 79% water, 20% glycerin, 0.5% sodium dodecyl sulfate, and 0.5% isothiazolinone. This solution helps prevent the membrane from drying out and bacteria from developing. Throughout transit, the sealed package must not break.
Storage:

When storing membrane modules, they must always be completely covered. The new membrane modules must be kept out of direct sunlight and in an environment that is dry, clean, non-corrosive, and unpolluted. The temperature range of the environment must be 0–40°C. Modules must be positioned in a designated area under supporting cover when being transported outside in order to protect them from the elements and the sun.
The membrane modules were placed within a vacuum packaging after being coated with a protective solution consisting of 79% water, 20% glycerinum, 0.5% sodium dodecyl sulfate, and 0.5% isothiazolinone. The maximum storage period is one year if the above parameters are met. The aforementioned formula for the protection solution on the surface needs to be updated after a year.
After the membrane is placed in the membrane tank, the membrane module needs to be thoroughly cleaned before the system is restarted during a brief system halt. In certain instances, the membrane tank needs to be chemically cleaned before adding protection solution (5 mg/L NaClO) to soak the membrane. Operators need to replace the membrane tank's protective solution right away if the concentration of NaClO in the membrane tank is less than 0.5 mg/L.

MBR MEMBRANE Characteristics
Constantly hydrophilic characteristics
High permeability is provided using a hollow-fiber PVDF membrane with high flux.
High effluent quality and flux (SDI < 2)
PVDF resin is used in the membrane elements, which allows for long-term use due to its strong chemical resistance and low chemical degradation.
Simple upkeep
The exceptional chemical resistance of PVDF resin produces a cleaning effect suitable for maintenance and recovery cleaning.
Water flow rises significantly.
Film wire with a special hole-forming technique.
Over 98% of it is porosity.
Water flux significantly increases under the same circumstances.
Enhanced strength of coating
By using polymer chemical dual modification and secondary extraction, the membrane wire coating was created.
Strong coating that is difficult to remove.
Extended design life, resistant to acids and alkalis, and requires little maintenance.
Potent power to prevent pollutants
Film wire is difficult to block and stain.
Prolongation of service life.
Design of Special Material Formulas
Pollutants are limited to the membrane's outside surface due to its distinct outer dense layer structure, which makes it difficult for them to get through the membrane's mesh hole.
Thin coating, which facilitates simpler dirt removal during cleaning and improves flux recovery performance.
