1) membrane separation technology used in the industry across the food industry, biochemical, pharmaceutical, petrochemical industry, power, paper, desalination, water treatment and other industries, different industries, different pollutants, different requirements, cleaning methods and pharmaceuticals are very different!
2) different pretreatment process will cause the film of the scale and loss of different treatment methods are different.
3) membrane material, film forming process is divided into many different models, the working parameters of these films are different, which derived from different cleaning methods.
4) Before cleaning the membrane need to determine in advance whether the value of cleaning, cleaning effect is expected.
