Detailed product description of Polyacrylamide (PAM) in sewage treatment

Polyacrylamide (PAM for short) is a linear water-soluble polymer. With its excellent flocculation, adsorption, and bridging properties, it has become one of the most widely used high-efficiency organic flocculants in the field of sewage treatment. Through adsorption bridging and electric neutralization, it enables suspended particles and colloids in water to quickly coagulate into large flocs, accelerating solid-liquid separation. At the same time, it can realize functions such as sludge dewatering and water purification. It is widely used in municipal sewage, industrial wastewater treatment, sludge disposal and other scenarios, adapting to various water quality and process requirements. With low dosage, high efficiency and no secondary pollution, it is an indispensable core agent in the sewage treatment process.

I. Product Usage Characteristics

PAM can be divided into three types according to ion type: cationic (CPAM), anionic (APAM), and non-ionic (NPAM). Different types of products are specifically adapted to different stages of sewage treatment, with their usage characteristics each having different emphases. Details are as follows:

(1) Cationic Polyacrylamide (CPAM)

Core applications: Mainly used for sludge dewatering (the field with the largest consumption in sewage treatment) and flocculation treatment of high-organic matter wastewater. The molecular chain has positively charged groups, which can electrostatically attract negatively charged sludge colloids and organic pollutants, destroy the stability of colloids, and achieve coagulation dewatering and flocculation separation.

Application characteristics:

Special for sludge dewatering: Suitable for organic sludge generated in industries such as municipal sewage, printing and dyeing, papermaking, food, and chemical engineering. It can condition the sludge structure, promote the separation of water from the sludge, and facilitate equipment like plate and frame filter presses, belt filter presses, and centrifuges to press the sludge into cakes. It can reduce the moisture content of the sludge to below 80%, significantly reduce the sludge volume, and facilitate subsequent transportation and disposal. The higher the organic matter content in the sludge, the higher the cationic degree of the product to be selected (cationic degree is usually 20%-60%).
Treatment of high-organic wastewater: For printing and dyeing wastewater, food processing wastewater, breeding and slaughtering wastewater, papermaking wastewater, etc., it can flocculate organic colloids in the wastewater such as dye molecules, proteins, fiber debris, and feces. It also has a certain decolorization effect. When used in conjunction with inorganic flocculants, it can improve the treatment efficiency.

Biochemical system maintenance: In abnormal situations such as activated sludge bulking and sludge loss in the secondary sedimentation tank, adding a small amount can improve the sludge settlement performance, prevent sludge loss, and ensure the stable operation of the biochemical system.
Adaptation to pH range: It works best in acidic to neutral environments (pH 1-7). An overly alkaline environment will weaken the effect of positive charges and affect the treatment result.
(2) Anionic Polyacrylamide (APAM)

Core Applications: Mainly used in flocculation and sedimentation of industrial wastewater, as well as in the primary and secondary sedimentation processes of municipal sewage. The molecular chain contains negatively charged groups (such as carboxylate and sulfonate groups), which can interact with positively charged suspended particles in water. Through bridging and adsorption, large flocs are formed, accelerating the sedimentation and separation process.

Application Characteristics:

Treatment of high-turbidity inorganic wastewater: It is preferentially suitable for mineral processing wastewater, coal washing wastewater, sand and gravel processing wastewater, steel plant wastewater, etc. It can effectively adsorb suspended inorganic particles such as sediment, slag, and coal powder, accelerate sedimentation and stratification, and the reuse rate of clear water can reach more than 80%. At the same time, it can recover useful mineral resources in wastewater (such as coal powder and mineral powder).
Municipal sewage flocculation: In the primary sedimentation tank and secondary sedimentation tank links of municipal sewage, when used together with inorganic flocculants such as polyaluminum chloride (PAC), it can quickly remove suspended impurities and colloidal pollutants in the sewage, reduce the turbidity and COD of the sewage, and ensure that the effluent quality meets the standards (such as the Class 1A standard in the "Discharge Standard of Pollutants for Urban Sewage Treatment Plants").
Industrial wastewater auxiliary treatment: In the wastewater treatment of printing and dyeing, papermaking, chemical and other industries, it can assist in removing suspended solids and some pollutants from wastewater. When used in conjunction with cationic PAM, it can improve the treatment effect of complex wastewater.

Suitable pH range: Neutral to alkaline (pH 7-14) is more applicable. Acidic environments will affect its flocculation performance, so the pH value of water quality needs to be adjusted in advance.
(III) Non-ionic Polyacrylamide (NPAM)

Core Applications: Mainly used in acid-base wastewater treatment, tap water/drinking water purification, and flocculation of complex water quality. The molecular chain is overall electrically neutral, with strong acid and alkali resistance and no charge interference. It has a wide range of applications but a relatively slow flocculation speed, and is often used in combination with other flocculants.

Application Characteristics:

Acid-base wastewater treatment: Suitable for strong acid and strong alkali wastewater generated in industries such as chemical industry and electroplating. It has good stability in the pH range of 1-14, can effectively flocculate suspended impurities in wastewater, and avoid the impact of acid-base environment on flocculation effect.
Drinking water purification: For impurities such as algae, humus, and sediment in surface water sources like rivers and lakes, when used in combination with inorganic flocculants, it can enhance the flocculation effect, reduce the dosage of inorganic flocculants, lower the residual aluminum ions in the effluent, and ensure the safety of drinking water (must comply with the PAM standards for drinking water).

Complex water quality treatment: In the treatment of high-salt and high-hardness wastewater, it has strong tolerance, can effectively remove suspended solids in water, and solves the problem that other types of PAM are prone to failure in high-electrolyte environments.

Adaptable pH range: The effect is best when close to neutral (pH 6-8). It can still maintain a certain flocculation performance in acidic or alkaline environments, with strong adaptability.
(4) Common Characteristics

Efficiency and Energy Saving: Small dosage (usually 0.1-10mg/L), fast flocculation speed, which can significantly shorten the sedimentation time, reduce sewage treatment costs, and improve treatment efficiency. Compared with traditional flocculants, it can reduce the dosage by more than 30%.

Good Water Solubility: Easily soluble in cold water (cationic type has the fastest dissolution rate; non-ionic type requires heating and auxiliary stirring). After dissolution, it forms a uniform and viscous solution without obvious precipitation, which is convenient for dosing and use. High temperature (not exceeding 50-60℃) and high shear should be avoided during dissolution to prevent molecular chain breakage and degradation.

No Secondary Pollution: It is non-toxic itself, with no harmful residues after degradation. The treated wastewater and sludge can be disposed of normally (sludge must meet relevant environmental protection standards), and will not cause secondary pollution to water bodies and soil, meeting the requirements of green environmental protection. The content of residual monomers (acrylamide) is strictly controlled within a safe range.

Strong Adaptability: According to different sewage water qualities (turbidity, pH value, pollutant type) and treatment processes (sedimentation, air flotation, dehydration), products with different ion types, molecular weights, and degrees of ionization can be selected to flexibly adapt to various sewage treatment scenarios, improve the treatment compliance rate, and maintain performance in electrolyte solutions of a certain concentration.

ECHEMI Editorial Reference

Polyacrylamide is relatively stable to heat with its solid only being softened at 220~230 °C and its solution subjecting to significant degradation only at above 110 °C. Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water. It can be cross-linked by the
