Coagulants and flocculants for algae removal Adding aluminum sulfate as a coagulant can remove turbidity and algae at the same time. When the number of algae in the effluent is less than 1000/mL, the amount of coagulant required is much greater than the amount required when the turbidity is less than 3 NTU. The reason …
This week, our technicians went to the coal washing plant to conduct on-site polyacrylamide selection experiments on coal mine wastewater. We’re one of the top suppliers of water treatment chemicals in China. Our factory was founded in 1999, the company has successively built three major production bases covering an area of 58,000 square meters, …

Polyacrylamide (PAM) dosing conditions Dissolution conditions: ○ Water quality: The water used to dissolve PAM should be clean, neutral, and free of salt impurities. Avoid using water containing iron ions or other impurities that may react with PAM. ○ Temperature: It is usually recommended to dissolve PAM between 5℃ and 60℃. Too low a temperature …
5 major misunderstandings in the selection of polyacrylamide (PAM) 1: The larger the molecular weight, the better the effect Many users mistakenly believe that the higher the molecular weight of PAM, the better the flocculation efficiency and treatment effect. However, in fact, the best flocculation effect under different water quality conditions may correspond to a …

How to accurately select the type of PAM flocculant in sewage treatment? Suspended solids (SS) and turbidity: For sewage containing a large number of fine, difficult-to-sediment suspended particles, high molecular weight, high hydrolysis degree anionic PAM should be selected, because it has good bridging adsorption and net capture effects, and can effectively condense and precipitate …

There are two main types of flocculants used in the treatment of coal mine wastewater: inorganic flocculants and organic flocculants. In coal mine coal washing and wastewater treatment, polyacrylamide (PAM) is one of the most common types of organic flocculants. The following is a specific classification and its application in coal mine wastewater treatment: 1. …

Everyone knows that sewage treatment is inseparable from the flocculant polyacrylamide, or PAM. Polyacrylamide is widely used in water treatment, the textile industry, oil mining, printing and dyeing industry, paper industry, mineral processing, coal washing, breeding, building materials and other industries. It is known as an all-round product and is known as “auxiliary for all …

Common use of cations Generally, cationic polyacrylamide is used as a dewatering conditioner for sludge in water plants. However, water plants only use a little desludge agent in the pre-stage, and generally do not use it in the later stage, because there is not so much sludge in water plants. It is generally used in …
