Why Solid PolyAluminum Chloride Needs to Be Dissolved into Solution for Use
In water treatment, why is it necessary to dissolve solid polyaluminum chloride into solution for use? When solid polyaluminum chloride is directly added to wastewater, it typically requires 5-20 minutes to dissolve. If it is not fully dissolved before moving to the next treatment step, some of the polyaluminum chloride may not fully activate, leading to reduced effectiveness in water treatment.
Polyaluminum chloride, as an inorganic polymer coagulant, has strong flocculation ability to rapidly coagulate suspended solids and colloidal particles, helping improve water quality and reduce turbidity. It is widely applied in urban water supply, wastewater treatment plants, industrial wastewater treatment, swimming pool water treatment, papermaking industry, mining, and other fields. However, to ensure the full effectiveness of polyaluminum chloride, it is necessary to dissolve solid polyaluminum chloride into solution before use.
By dissolving solid polyaluminum chloride into solution, it ensures complete dissolution and uniform distribution in water, enhancing its treatment effectiveness and reducing waste. This not only improves the performance of polyaluminum chloride but also reduces costs, resulting in a more efficient water treatment process.
In conclusion, dissolving solid polyaluminum chloride into solution before use is an essential step in water treatment to ensure its full effectiveness, enhance water treatment outcomes, and reduce costs.
