What do you need to pay attention to when maintaining multi - media filter?
Multi-media filter is a kind of equipment that can filter the water quality, often as a lot of water treatment equipment pretreatment exists, can initially treat the water quality, so that the water quality can meet the needs of the use of equipment behind. After a long time of use, the multi-media filter needs to be maintained to make the operation of the equipment more stable, and the maintenance is also a lot of matters that need to be paid attention to, here is a simple understanding of it!
Before understanding the main points of maintenance, we should first understand why to maintain the multi-media filter, multi-media filter is a kind of use of the characteristics of various filter materials to filter macromolecular organic matter, residual chlorine, iron oxide and other substances in the water, multi-media filter will use activated carbon filter material, it is different from other filter material, It through adsorption to remove impurities, but this adsorption is irreversible, activated carbon has the corresponding adsorption capacity, once adsorption saturation, also lost the function of adsorption, can not use backwash method to flush away pollutants. There is activated carbon adsorption of organic matter, will also provide rich nutrition for bacteria, resulting in a large number of bacterial reproduction, the content of microorganisms will rise after treatment.
Therefore, when we are maintaining the multi-media filter, we should carry out regular backwashing before the activated carbon adsorption saturation, to flush out a large number of bacteria and suspended solids on the surface of activated carbon. If the adsorption of activated carbon is saturated, it needs to be replaced, otherwise it can cause damage to the equipment behind.
Through the above introduction we have an understanding of the precautions of the multi-media filter, but also know how important the maintenance work is. So in the use of multi-media filter can not ignore the maintenance work, to carry out regular maintenance, so as to extend the service life of the equipment.
