Directions: L/m2. h refers to the water output of a flat rice film for an hour in units such as:19L/m2. h Refers to 19 litres of effluent from a flat rice membrane for an hour

For large-scale mbr film projects, especially for complex industrial wastewater, it is best to explore and verify the process and design parameters by trial or pilot tests

APPLICATION :

Variety industry wastewater and municipal sewage and has achieved many reference in recycling sewage,

polysilicon wastewater, chemical fiber wastewater, papermaking wastewater, slaughterhouse wastewater and leachate.




Use conditions and methods

1. Hydrophilic and moisturizing membrane

Reinforced composite PVDF membrane uses hydrophilic modified PVDF raw materials, the membrane has good hydrophilicity, and no hydrophilic treatment is needed in the site. However, if the diaphragm is not put into use immediately after it is installed, or it needs to be parked for a certain period of time during use, please ensure that the diaphragm is immersed in water or it is always in a wet condition.

2. Maintenance of membrane flux and membrane cleaning

Diaphragm aeration system construction using perforated aeration, aeration of bubbles and water flow, so that the film full of jitter, to achieve self-cleaning of the membrane. Using the intermittent operation mode, the self-priming pump can suck for 10 to 12 minutes and stop for 2 to 3 minutes, which can effectively prevent the clogging of the membrane holes and ensure long-term and stable operation of the membrane separation. When used for the first time, the microbiological culture of the biochemical pool achieves good activity, and the membrane is only put into operation when the viscosity is small.
