Multi - medium filter can effectively intercept large particles of impurities, suspended solids in water, reduce the degree of water. The effluent quality is SDIS3.
This system is equipped with an OlOOOmmx 3000mm stainless steel filter, the filter is filled with fine quartz sand with good grading, the particle size is 0.6 ~ 2.2mm, the height of the filter layer is greater than 1200mm, the turbidity of the effluent water is less than 3.
Under normal production conditions, backwash usually according to the filter inlet and outlet water pressure difference, general pressure difference is greater than O.lMpa, it must be backwash the filter.
Active family filter:
Activated carbon adsorbers are used to absorb odors from water. Residual chlorine, particulate impurities, organic matter and other harmful substances, effectively reduce the color of water, improve the taste of water.
This system is equipped with a 1000mmx3000mm stainless steel filter, filter filled with particle size of 20 ~ 40 mesh high quality coconut shell activated carbon, effective height of 1200mm, effluent water color less than 2.
Under normal production conditions, backwash generally according to the filter inlet and outlet water pressure difference, _ pressure difference is greater than.IMpa, the filter must be backwash.
Ultrafiltration membrane is a kind of filtration between microfiltration and nanofiltration, which is a membrane separation technology suitable for substance separation, concentration and purification. In practical applications, it is generally characterized by the interception molecular weight, as long as it is used to separate large molecules, colloids and particles in solution from small molecules such as solvents.
The macromolecules, colloid and particles are trapped on the surface of the membrane, and are taken away by the circulating flow of substances into concentrated liquid, so as to achieve the purpose of substance separation, concentration and purification. Applications of ultrafiltration mainly involve food, beverage, biomedicine, fine chemical industry, industrial wastewater treatment and reuse.
Ultrafiltration membrane technology:
In our country, the application of ultrafiltration technology has a dominant position in juice clarification process. The newly pressed fruit juice contains pectin, pulp debris, starch, protein, suspended solids, microbial metabolism and other substances that cause the juice to be cloudy.
Ultrafiltration was used to clarify the juice, and small molecules such as sugars, organic acids and water could pass through the membrane. Most of the macromolecular materials were intercepted to obtain clear and sterile juice. Ultrafiltration process does not require a filter aid; Short process, low labor cost; It is a more economical method of juice clarification.
CIP cleaning system can ensure a certain cleaning effect, improve the safety of products; Save operation time, improve efficiency; Save labor and ensure operation safety; Save water, steam and other energy sources, reduce the amount of detergent; Production equipment can realize large-scale, high level of automation; Prolong the service life of production equipment. The chemical energy of CIP cleaning is mainly produced by adding chemical reagents, which is the main factor determining the cleaning effect.
