When the quartz sand filter in the water treatment equipment is backwashed, if the air auxiliary backwashed is added, what does the air equipment include? How to design and select? 1. Compact structure: the equipment integrates coagulation reaction, filtration and continuous cleaning.The process flow of water treatment is simplified, the floor area is small, the structure is simple, and the single and installation operation is flexible and convenient.Reduce the energy consumption and labor management costs of the original water treatment process,Reduced the difficulty of operation.2. the effect of coagulation reaction is obvious: the application of coagulation reaction mechanism and sedimentation mechanism,Effectively remove suspended solids and colloidal substances in the water,It is conducive to further reducing the turbidity of the effluent in the sand filter area.3. continuous self-cleaning and filtering: automatic circulation of filter media,Continuous cleaning,Backwashing without downtime.4. reduce
What is the use of air purifiers? The main role of the air purifier is,Filter harmful gases such as particulate matter, sterilization and formaldehyde removal.This is the principle of purification,Different Purification Principles have different purification effects. according to the working principle of air purifierThere are three main types: passive, active and active.According to the air purifier for the removal of particulate matter in the air,There are mainly mechanical filter type, electrostatic stationary filter type, high-voltage electrostatic dust collection, negative ion and plasma method.Mechanical filtration generally captures particles in the following four ways: direct interception,Inertia collision,Brown diffusion mechanism,Screening effect,It has a good effect on the collection of fine particles but has a large wind resistance,In order to achieve high purification efficiency,The resistance of the filter screen is large,Moreover, the filter screen needs to be dense to reduce its life,Regular re
