Three important purchase indicators of polyaluminium chloride
With the development of industry, the environment on which people live is getting worse and worse, and environmental protection has become a cause that everyone of us should participate in.Polyaluminum chloride manufacturersThe products produced can be used to treat sewage, river water, reservoir water, groundwater, urban sewage, industrial water purification, various industrial wastewater, industrial wastewater and waste residue in the recovery of useful substances, polyaluminium chloride is also used in sugar refining, pharmaceutical refining, cement quick setting, cosmetics raw materials and other industries. So with the wide application of polyaluminum chloride, how should many customers choose the quality of polyaluminum chloride products?
The selection criteria of polyaluminium chloride mainly depends on the three important indicators of alumina content, base degree and PH value.
The alumina content isPolyaluminum chloride manufacturersThe measure of the effect of the product, it has a certain relationship with the relative density of the solution, generally speaking, the greater the relative density, the higher the alumina content. According to the content of aluminum oxide, it can be generally divided into several specifications of 30%, 28%, 26% and 24%. Perhaps most people think that the higher the content, the better the effect. However, if the water quality of some sewage is too acidic, and high content of polyaluminum chloride is used again, the phenomenon that suspended solids will not precipitate after putting in will occur.
The basicity of polyaluminum chloride is also sometimes referred to as the degree of alkalinity. GeneralPolyaluminum chloride manufacturersThe basicity is controlled between 40% and 95%, this standard can be adjusted and can be customized according to the needs of users. General common products such as industrial grade polyaluminum chloride, basicity of about 85%, and in drinking water grade polyaluminum chloride, basicity of about 45%. In the production of polyaluminum chloride, the lower the basicity, the production of raw materials will increase, so the higher the basicity, the lower the cost. But not the higher the basicity, the better the product effect, it depends on the specific use of the environment.
Before using polyaluminium chloride, it is necessary to understand the PH value range of polyaluminium chloride, and then measure the PH value of water, and the appropriate PH range can achieve excellent use effect. When the PH value of polyaluminum chloride is not reached, in order to make the flocculation of raw water better,Polyaluminum chloride manufacturersIt is usually necessary to adjust the pH value of the raw water. Only by adjusting the pH value of the water to the pH value range of the polyaluminum chloride can a significant flocculation effect be achieved.
