Technical principle and characteristics of membrane-bioreactor
In the membrane-bioreactor, because the membrane module is used to replace the secondary sedimentation tank in the traditional activated sludge process, the solid-liquid separation can be carried out, and the water quality of the effluent in the traditional activated sludge process is not stable enough, and the sludge is easy to expand., Which has the following advantages:

Chemical Cleaning of Reverse Osmosis Membrane
The cleaning of the membrane is generally divided into physical cleaning and chemical cleaning, and the higher the frequency of chemical cleaning, the greater the damage to the membrane, which seriously affects the service life of the membrane system. Therefore, it is difficult for the relevant technical personnel to master the chemical cleaning of the membrane system.

The importance of reverse osmosis glass fiber reinforced plastic membrane shell in water treatment
The quality of the reverse osmosis glass fiber reinforced plastic membrane shell in the water supply pretreatment directly affects the service life of the reverse osmosis membrane. No matter whether the water quality of the water supply is surface water or groundwater, it will contain some organic and inorganic pollutants. If these pollutants are directly fed into the reverse osmosis system for operation without pretreatment, those pollutants and suspended solids will remain on the surface of the membrane, causing blockage of the flow channel, increasing the pressure of the membrane element, decreasing the water yield and desalination rate, and even causing serious consequences such as membrane pollution or membrane damage.

Softened water equipment is mainly used to remove calcium and magnesium in the water and other hardness ions, reduce the production of scale. So what is the reason why softened water equipment does not produce soft water or does not operate?

Water treatment equipment identifies and processes chemicals
For non-carcinogens, there is a clear dose-response relationship for their toxic effects, which do not cause harmful effects below a certain dose level, which is called the "threshold". Water treatment equipment When setting limits for these chemicals, they are calculated based on the Tolerated Daily Intake (TDI).
