Manganese sand filter is the main hero of groundwater in addition to iron and manganese, because he used the effect is good, long life, so by the majority of consumers. But also because manganese sand filter life is very long, it is easy to lose vigilance and forget to detect water quality, so as to forget to replace the manganese sand filter. To be able to replace the filter in time, people want to know urgently manganese sand filter under what circumstances need to be replaced, take a look below. Manganese sand filter after a period of time, from the water will gradually filter out iron and manganese sand filter is attached to the surface, forming a layer of rust, however, we need to be aware that this is not manganese sand filter useless logo , no rust will appear after replacing the manganese sand filter, because the rust formed on the surface layer of active filter, which still has the effect of active membrane layer in addition to iron, so there is not rust manganese sand filter needs to be replaced signs . If rust occurs when the replacement of manganese sand filter, will result in waste manganese sand filter. So what is the manganese sand filter needs to be replaced a sign it? Often tested the water quality, water quality in the ferromanganese element when higher than normal when it is time to lose the effect of manganese sand filter, manganese sand filter also needs to be replaced time. Recently, consumers have to consult us "well water after yellow after manganese sand filter processing can not go yellow reason." Why is this? Here by the company's technical staff to answer your questions: First, look at us, manganese sand filter, manganese sand filter effect of removing iron and manganese, manganese dioxide component which is the main iron and manganese manganese sand filter manufacturers, we To say it clearly is one of manganese sand filter functionality is in addition to Manganese sand prices, followed by the removal of iron, so sometimes there will be water through the sand filter manganese processing after the case is still yellow. Water, yellow is a sign of excessive iron in water, the reasons for this situation are 3:00 First, quality manganese sand filter of non-compliance. Manganese sand filter on the market, especially SMEs producing manganese sand filter manganese sand filter production base, because they do not pursue the reasons for the brand, in order to save the cost of which contains a lot of impurities, resulting in the use of manganese sand filter is not enough ability to iron. Second: the water is too serious excessive iron and manganese sand, it has exceeded the capacity of manganese sand filter. In addition to iron and manganese sand filter capacity there is a limit, and manganese sand filter water treatment material is both ways - both to the removal of iron ions, but also to the removal of manganese ions, although from a functional point of relatively complete, but not as good as a single from the use of iron products in addition to good effect, so if iron ions in water than the standard, you would not be able to remove the water well exceeded the iron ions. Third: the surrounding groundwater system by the sewage plant.
