The descaling and anti-scaling of paper mills is divided into two parts: the ordinary process cooling water cycle, which is cooled by liquids with fewer impurities such as oil, and the other part, which is the reuse of water containing a large amount of pulp and so on. The former is simpler to handle, while the latter is more difficult to handle. As the principle of Hydropath electronic descaler is physical flocculation, it has flocculation effect on tiny particles such as pulp, so the effectiveness of descaling and anti-scaling is not only for calcium carbonate and so on. Hydropath electronic descaler can cope with many complex environments, which is incomparable to other products。
