The fundamental problem of water supply pipe chemicals is the sterilization of bacteria and viruses through the introduction of chlorine disinfectants, but it is impossible to control the acidification and corrosion of rust and water.Corrosion control is possible to some extent with the introduction of an alkali agent, but it is impossible to control scale and alkalinity and water hardness.

France, the United States, Germany, Europe, and Japan have conducted research and efforts to exclude chemicals (chlorine, alkalis, and acidic agents) from tap water, but their technical results show that chemicals (chlorine, alkalines, acidic) are heavily weighted.As a method of dilution, we have maintained the water supply network so far.

WCS Co., Ltd. is a product that can solve the fundamental problem of water supply (NCW) .It is a technical product (currently up to 10% ± 4) with the same pH and 30% or more of corrosion control performance before and after the tap water passes through the NCW product., Germany, Europe, etc. Water pipe network management The world's first company that has the technology of maintaining clean water piping to catch green water, scale, and bacteria without using drugs that have not been solved (drug exclusion) for 100 years.It is a Korean company that has the technology of maintaining tap water in the clear water supply network.
