There are many components in pure water equipment that need to be cleaned and replaced regularly to ensure the quality of the effluent. The most important one is activated carbon. How often does this need to be replaced?

The normal service life of activated carbon for pure water equipment is 8-24 months. Our company uses high-quality coconut shell activated carbon for all activated carbon products, and the efficacy and territorial sovereignty are determined by excluding biological macromolecular organic compounds, iron oxides, and permanganate indices. Organic compounds, permanganate index, and iron oxides can easily poison ion exchange epoxy resin, while permanganate index and positive ion surfactants not only poison epoxy resin, but also continue to damage membrane structure engineering, rendering RO reverse osmosis membranes ineffective.

The calculation of the replacement cycle of activated carbon in a pure water system is best based on the judgment of the adsorption capacity of activated carbon. The method is to sample the water before the activated carbon, sample the water after the activated carbon, and test it with a residual chlorine detector or color card comparison table. If the adsorption capacity is low, it should be replaced.

The replacement time of activated carbon must be distinguished based on the quality and water quality indicators of activated carbon. All normal sewage treatment uses activated carbon for replacement once a year. In fact, there is no requirement for the actual replacement time of activated carbon. Generally, after the activated carbon loses its adsorption saturation state, it can be discarded and replaced with a new one. Simple contrast detection: Put activated carbon into the water and observe that there are many bubbles in the water. If there are fewer bubbles (compared to new activated carbon), it indicates that the contrast is full and must be replaced or rebuilt.

How often should the activated carbon on the pure water equipment be replaced? It is best to calculate the replacement cycle time of activated carbon for mineral water based on its adsorption capacity. The method is to take samples from the water before activated carbon and from the water after activated carbon. Use residual chlorine detector or color card comparison table to check if the absorption amount is low and should be replaced.

Everything is normal, and it should be replaced every 12 months. It also depends on the condition of the source water body. If the water body is poor, the time will be shorter and shorter. There are also cases where the suction work ability is low and needs to be replaced, requiring professional technical testing. Generally, unless the working pressure of the source water is very high, it is necessary to start the original centrifugal water pump for cleaning, and the working pressure of drinking water cannot be cleaned.
