Resin life: 001X7 is a strong acidic cationic resin, the service life is generally about 5 years, the key is to look at the incoming water quality. The main factors affecting the life of the resin: chemical, biological, organic pollution, such as feed water containing oil, excessive metal oxides, etc. Note: In the pretreatment process to prevent residual coagulant into the resin. This kind of pollution will block the resin exchange channel, consume the resin exchangeable group, reduce the exchange capacity. Physical wear and tear: the resin in the regeneration, backwashing process of mutual friction, constant transformation of volume changes, and changes in water temperature will reduce its mechanical strength, resulting in breakage. Whether the resin reaches the service life, can be measured by the appearance of the color, breakage rate, exchange capacity, the cycle of water production, etc., the key point is whether its operating costs have been economic.
