Haiyou, if too much sodium hypochlorite is recovered, why is it prone to contain phosphine? ? 2. We use waste sodium hypochlorite (that is, the waste sodium hypochlorite remaining after phosphine removal), water, and fresh sodium hypochlorite for its preparation. The effective chlorine level is between 0.085% and 0.12%. But I understand that the reasons for the inefficacy of sodium hypochlorite include decomposition at high temperatures and decomposition when the pH is too low; I still don’t understand what causes the low volume of water used in the process ? ? It’s the water that needs to be added when configuring sub-nano, right? ?
A smaller amount of water used has an impact on the absorption efficiency of hypochlorite. Does this mean that, at the same concentration of hypochlorite, a smaller amount of water leads to insufficient circulation volume and poor spraying effects, thereby causing the hypochlorite to become ineffective more quickly?
I’ve never understood what is meant by the circulation volume – does it refer to the amount of water circulated by the pump in the purification tower, or rather the amount of water added during preparation? Personally, I think no water is added when the purification tower is in operation; instead, waste water, that is, water that has been recycled, is used together with fresh water to create water that meets the required standards.
Sodium hypochlorite can be prepared in two ways: one is by adding water to the ready-made sodium hypochlorite, and the other is using an alkaline solution plus chlorine gas along with preparation water. You are referring to the former, while I am talking about the latter
