The latest scientific research results of central air conditioning cooling water treatment-the State Administration of Taxation took the lead in trying It is conducive to improving the practical efficiency of central air conditioning,Extend the service life of the central air conditioner.In the operation of the open cooling tower,The circulating cooling water in the system has a lot of contact with the air,Let the CO2 in the water escape into the air,The carbonated equilibrium state in the water is destroyed;On the other hand, dissolved oxygen in cooling water causes unstable water quality,To cause scale and corrosion in the system;At the same time, organic matter and microorganisms in air dust will also be brought into the water,Continuous breeding and accumulation,Form bio-clay.Scale, corrosion and bio-clay produced by the above action,The three are connected and influenced by each other.Salt scale is combined with dirt to form the particles,Scaling and clay can accelerate corrosion an

Other types of filters For filter performance test bench,This kind of test bed must strictly purify the system before the test,Therefore, the test system and the pollution injection system serving the test system need to be equipped with filters,In this, the filter and the filter being tested are two different things,Its accuracy requirements,The dirt capacity requirement is higher than the filter precision tested,To distinguish the two types of filters in the same test system,This filter is called a test bed filter,The filter being tested is called the filter being tested.The most commonly used method of mechanical filtration sewage treatment,Depending on the filter media,Mechanical filtration equipment is divided into two categories: Particle Media filtration and fiber filtration,Particle Media filtering mainly uses granular filter materials such as sand and gravel as filter media,Through the adsorption effect of particle filter material and the interception effect of pores between sand particles on solid s
