What's The Difference Between Wastewater PAC & Drinking Water PAC?
PAC polyaluminium chloride can be used for industrial wastewater treatment or drinking water treatment. So many people have doubts, can industrial water treatment be used to treat drinking water? Is it really safe?
1. Polyaluminum chloride for industrial wastewater treatment: The appearance is dark brown or dark yellow, and the content is between 25% and 28%. The production method used is drum type. The polyaluminum chloride produced by this process is a polymer flocculant and a new water treatment agent developed on the basis of traditional aluminum salts and iron salts. Low production costs and low net worth. The water purification effect is very good. It is widely used in the treatment of various industrial water and urban sewage.
2. Polyaluminum chloride for drinking water treatment: The appearance is yellow or gold, and the content is generally 30%. The reason for using high-content polyaluminum chloride agent to treat drinking water is because of the low content and the traditional polyaluminum chloride processing raw material iron, etc. Heavy metals are harmful to the human body. The production type of this reagent is mainly plate and frame pressure filtration type or spray drying type. Its manufacturing cost is slightly higher than industrial polyaluminum chloride. It is a new type of efficient and stable water purification agent that is widely used in various water treatment plants and drinking water circulation treatment.
