Products on displayadvantages of KaiDeFei(KDF)



1 KaiDeFei(KDF) has longer service

lifetime,besides SiO2,KDF is the longest service lifetime filter media. there are two conditions that will shorten its service lifetime,both will take quite a long time.

1.1 When the amount of residual chlorine in water is lager than the dissolved amount of zinc, running water with 0.55ppm of residual chlorine will produce only 0.25ppm of zinc while passing KDF filter material.This means that 100ppm of residual chlorine can be removed without excess of zinc.

2.2 The other case is the hysical egradation of KDF.But corrosion,friction or consumption,for example,make little effection on the service life time of KDF.The service life time of KDF is above 10years at least.

2、The low cost of KaiDeFei(KDF)

KDF compares with activated charcoal Pellet

As a kind of long service lifetime and multifunctional filter material,KDF has obvious advantages campares with activated charcoal.

Fistly,KDF can remove most of the extraneous constituents,such as residual chlorine,heavy metal and sulphide.KDF reduces mineral substance,sterilizes bacteria,it has exellent filtering effect and fast flow speed.

Secondly,KDF has long service lifetime,with no need of regeneration and isn't easily out of action.Its service lifetime is between 10-20 years or so.life-time service reduces the cost of running charge,it can be appllied in acid medium.

KDF is very clean its fliteration accuracy can reach to 20-50μ,and can be used together with arenaceous quartz.

一、KaiDeFei(KDF) works in high-temperature environment

Traditional water treatment filtering media mainly depends on physical adsorption,but adsorption effect reduces when the temperature rises.Therefor traditional water treatment filtering media is limmted to operate in normal temperature environment,otherwise,temperature reduction or heating water would bring big extra cost and consume much more energy.

On the contrary,KDF has outstanding characteristic in high or low temperature environment,affected little by temperature.Through microelectronic chemical adsorptionm,KDF filters water directly in high temperature environment.That means the big problem that traditional water treatment filtering media can not work in high temperature environment is solved,which reduces cost and increaces benefit,extremly to hotels and Villa thermal spring.

water.KDF will have broad term market outlook.
