High molecular weight Polyacrylamide PAM for sewage clarifying agent
Polyacrylamide, alias PAM, is a glassy solid. It is easy to absorb water, and the rate of water absorption differs depending on the nature of the derivative ion. Polyacrylamide dissolves in water and also dissolves in organic solvents such as acetic acid, ethylene glycol, glycerin, and amines. Long-term thermal decomposition, decomposition temperature above 120 °C. Carbonized to a black powder at 210°C under anaerobic conditions. According to need, polyacrylamide can be processed into four types of products by non-ionic processing into anion, cation and mixed Anionic and cation.
1. Industrial wastewater treatment
Especially for suspended particles, sewage treatment with relatively coarse, high concentration, positively charged particles, neutral or alkaline pH of water, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. .
2. Drinking water treatment
Many water plants come from rivers. The sediment and mineral content is high, and the turbidity is relatively high. Although the sedimentation and filtration are still unable to meet the requirements, it is necessary to add a flocculant. In the past, water plants used inorganic flocculants, but the amount of dosing was large, resulting in poor sludge volume increase. Anionic polyacrylamide is used as a flocculant, and the dosage is 1/50 of inorganic flocculation, but the effect is several times or even several times that of inorganic flocculant. For rivers with serious organic pollution and cationic polyacrylamide, the use of better effect.
3. Paper Additives
The papermaking industry can be used as a clarification and retention aid for caustic soda, a filter aid, and a wet and dry strength enhancer for paper.
4. Sugar industry
Used as a juice clarifier.
5. Aquaculture
Used as an additive and binding agent in aquafeeds.

Polyacrylamide itself is not toxic. Only when the amount of inhalation is greater than five thousandths is harmful because the absorption of nutrients by the gastrointestinal mucosa is blocked. Residual acrylamide monomers in polyacrylamide are toxic and food applications must be strictly controlled. Storage, transportation should pay attention to moisture.
