The microorganism supersession outcome can bring about grave deposit's adhering .Problem such as equipment corrosion, bacterium and microorganism breeding, dirt propagating and sludge it forms, many kinds of bacterium are fatal, which can follow in the air and bring about threat to person health.。The exposure of chilled water system in atmosphere can result in microorganism and dirt in tower pool very easily. With the concentration of foreign substance ion in water and the changes of temperature, it is quite easy to lead to system tube wall encrust and corrode, which would make running condition worse,and slow down system running efficiency, rise energy consumption, increases malfunction. The service lifetime is greatly shorten in this way.To improve water quality , is to avoid all the bad effect mentioned above, improve operating condition, and make equipments work in a good condition with long service lifetime.
KDF can remove oxide and heavy metal, reduce the amount of suspended solid and mineral scale, restraining the breeding of microorganism. KDF can improve efficiency of air-conditioning, protect equipment and prolong its life time, reduce the frequency of repairing, ensure that the system works regularly.

Another main factor for boiler corrodes is Fe3 +. Most of office buildings and guesthouses now use hermetic heating system, condensation water ruse accounts for about 80% of boiler feedwater. If the steam pipeline, condensation water pipeline ,heat-exchanging apparatus are in lack of necessary postpone abrasion measures, iron outside the pipeline would dissolve into condensation water soon, which would accelerate the speed of boiler corroding greatly because Fe3 + has strong oxidbillity.
KDF is high-purity copper and zinc pellets，With its unique electrochemistry adsorption principle, KDF can remove Fe3+,foreign substance, and purify water. In this way KDF can postpone boiler scale formation, longthen service lifetime of boiler, and save its fuel, making sure the boiler running safely and economically.

Swimming pool water disinfection takes the amount of residual chlorine in the water as a standard, all the countries in the world have to check if the quality of swimming pool water has reached the standard. In China the standard is 0.4-0.6mg / L for residual chlorine in the water.
KDF filtering material can remove residual chlorine in the water by 99% and heavy metal by 98%,through its unique electrochemistry oxidation-reduction reaction, KDF also reduce solid suspended substance, mineral scale, restrain microorganism breeding .
