We’re a polyacrylamide factory in central China, for 26 years, we focus on producing the anionic and cationic polyacrylamide and non-ionic types, mainly used for wastewater treatment and sludge dewatering. Premium performance at competitive price.
Polyacrylamide is highly recommended in wastewater treatment due to its unique properties and effectiveness in various applications. Here’s why it stands out:
1. Superior Flocculation Performance
Polyacrylamide is widely used as a flocculant in wastewater treatment. It works by causing smaller particles to coalesce into larger flocs, which can then be easily separated from water through sedimentation or filtration5. This process is crucial for removing suspended solids, organic matter, and even some heavy metals from wastewater.
2. Biocompatibility and Safety
Unlike some chemical flocculants, polyacrylamide is non-toxic and non-biodegradable, making it safe for use in water treatment systems1. Its inert nature ensures minimal environmental impact, and it does not produce harmful byproducts during the treatment process.
3. Versatility and Efficiency
Polyacrylamide is effective across a wide range of wastewater types, including industrial effluents and municipal sewage. It can be tailored to specific needs by adjusting its molecular weight and charge, enhancing its ability to target different pollutants5. This adaptability makes it a preferred choice for both large-scale and specialized treatment applications.
4. Longevity and Cost-Effectiveness
Polyacrylamide-based treatments are known for their durability, often requiring less frequent reapplication compared to other flocculants1. This reduces operational costs and maintenance efforts, making it a cost-effective solution for long-term wastewater management.
5. Environmental and Regulatory Compliance
With increasing regulatory scrutiny on water quality, polyacrylamide’s safety profile and efficiency help facilities meet stringent environmental standards3. Its use aligns with sustainable practices by enabling the recovery and reuse of treated water.
In summary, polyacrylamide’s combination of effectiveness, safety, and adaptability makes it a highly recommended choice for modern wastewater treatment systems.

Today’s comparison test of paper mill wastewater: The client’s sample also flocculate, but very small floc and creaming fast showing its unstable character. For our 20% ionic floculant, the floc is big and stable, good for sludge dewatering. Welcome to inquire more details. Or contact Rita at: wa.me/8617737518864
Dear friends, this is Rita from a 26-year experienced Polymer factory in China, selling PAM +PAC chemicals for wastewater treatment.
Today I’d like to share some about PAC.
PAC products are widely used coagulant, but color, valid content may be varied at different price.
For the same industrial Grade, if the weight varies, then:
light cargo, valid content a bit lower, can only load 20-21 tons;
heavy cargo, valid content higher, can load 25-26 tons;
valid content differ will lead to more dosage of chemical; If you can accept this cost, then it’s ok to buy lower price products.
But for international business, the freight is expensive esp. for PAC chemical. In my view, it’s better to use high content chemical with more container loadability. Freight per ton V.S. chemical price margin per ton
Hope you can contact Rita on Whatsapp: wa.me/8617737518864 for more details.
Influent and effluent treatment uses a variety of chemicals, including coagulants and flocculants like ferric chloride and aluminum sulfate to clump particles, disinfectants such as chlorine and ozone to kill microbes, and pH adjusters like lime and sulfuric acid to control acidity or alkalinity. Other chemicals like polymers and hydrogen peroxide are also used to aid in separation and break down contaminants.
Coagulants and flocculants
Coagulants: These chemicals, like aluminum sulfate, ferric chloride, and polyaluminum chloride, neutralize the negative charge of suspended particles, causing them to clump together.
Flocculants: Often polymers (like polyacrylamide), these are added to the water to bind the smaller clumps into larger, heavier particles called “flocs,” which can then be more easily removed by settling or filtration.
We’ve been producing the cationic polyacrylamide for sludge dewatering, anionic polyacrylamide for waste water treatment for 26 years. Well ready for your call~
Application Scenarios PAM is primarily used as a flocculant in the pretreatment stage of desalination, removing suspended solids, colloids, and organic contaminants from raw water to improve water quality and reduce the burden on subsequent treatment processes (such as reverse osmosis membranes).
Product Types Based on their ionic properties, PAMs are categorized into three types: anionic, cationic, and nonionic. Nonionic PAM (NPAM) has proven effective in desalination due to its wide applicability and pH sensitivity. For example, a desalination plant in Zhoushan successfully extended its membrane fouling cycle by three times by using nonionic PAM.
Precautions Dosage Control: Excessive use may make floc separation difficult or affect subsequent process performance. Experimental optimization of the dosage is necessary.
PH Adjustment: The pH value must be adjusted based on the PAM type. For example, aluminum salt flocculants work best at low pH.
Compatibility: Interactions with other water treatment chemicals (such as scale inhibitors) must be considered.
You may have already felt the increasing price of PAC(polyaluminum chloride) products. While the PAM (polyacrylamide) price is likely to increase as well… Cold winter is coming~
Our price is still steady, hoping to get more clients. Please kindly contact Rita for price details. Whatsapp: https://wa.me/+8617737518864
Since the third quarter of 2025, the water treatment chemical industry has been experiencing unprecedented price volatility. Polyaluminium chloride (PAC), a core product, led the price surge. In September, Gongyi City Water Purification Materials Company raised the unit price to 25 yuan per bag, reaching the industry’s peak for the year.
Following closely, polyacrylamide (PAM) manufacturers announced a 200 yuan per ton price increase in late September, resulting in a combined effect of rising prices for both raw materials.
This price fluctuation has transcended typical seasonal fluctuations. Rising costs for raw materials like bauxite, production capacity reductions due to tightening environmental protection policies, and surging demand for industrial wastewater treatment have combined to create a triple pressure for continued price increases.
More seriously, the price increase is being transmitted down the supply chain, causing operating costs for water treatment companies to rise sharply. Some small manufacturers have suspended production and are waiting to see what happens. The industry as a whole has entered a severe winter period of high costs and high barriers to entry.
The core drivers of this round of water treatment chemical price fluctuations are multifaceted. From the supply side, the persistently high prices of basic raw materials like bauxite directly drive up PAC production costs.
PAM, on the other hand, is subject to fluctuations in international oil prices, further exacerbating cost pressures.
Environmental protection policies have become another key variable. Following the implementation of the newly revised Water Pollution Prevention and Control Law, small and medium-sized enterprises have been forced to invest heavily in technological upgrades to meet emission standards. Some outdated production capacity has been withdrawn from the market, leading to a contraction in overall supply in the industry.
On the demand side, there has been a rigid growth trend. With stricter industrial wastewater discharge standards and expanded municipal wastewater treatment capacity, demand for PAC in the papermaking, printing and dyeing industries has increased by nearly 15% year-on-year. Meanwhile, the use of PAM, a deep treatment agent, in wastewater treatment in chemical parks has surged. This supply-demand disparity has been amplified by rising logistics costs. High fuel prices have increased transportation costs to 12% of total costs, forming the final link in the price transmission chain. Notably, the price increases of related products such as monoammonium phosphate reflect the fact that cost transmission across the entire chemical industry chain has entered a resonant phase.
Sorry we can’t provide specific price range of PAC chemicals, please kindly note that PAC also comes in different grades and product types, and its price also varies depending on the specific product and supplier, but it is generally affected by product grade and usage. (Like the color, valid content, etc)
Factors Affecting Price
Product Type and Grade: Both PAM and PAC are categorized into different types (e.g., anionic/cationic) and grades, which directly impact their prices.
Supplier and Purchase Quantity: Different suppliers may have different pricing strategies. Larger quantities (e.g., greater than 100,000 kg) often offer lower prices. Product Quality and Application: PAM products used in specific applications, such as oil drilling, may also have different pricing.
Water purification chemicals are primarily used in the tertiary treatment phase.
Wastewater treatment is typically divided into three stages:
Primary treatment: Physical methods (such as screens, grit chambers, and primary sedimentation tanks) are used to remove suspended and floating solids, achieving a BOD removal rate of approximately 30%.
Secondary treatment: Biological treatment (such as the activated sludge process) is used to remove colloids and dissolved organic matter, achieving a BOD removal rate exceeding 90%.
Tertiary treatment: Chemical or physical methods (such as coagulation, filtration, and reverse osmosis) are used to further remove pollutants such as recalcitrant organic matter, nitrogen, and phosphorus. Water purification chemicals (such as coagulants and disinfectants) are typically used in the tertiary treatment phase to further purify water quality.
Produtos químicos para purificação de água são utilizados principalmente na fase de tratamento terciário.
O tratamento de águas residuais é normalmente dividido em três etapas:
Tratamento primário: Métodos físicos (como peneiras, câmaras de areia e tanques de sedimentação primária) são utilizados para remover sólidos em suspensão e flutuantes, atingindo uma taxa de remoção de DBO de aproximadamente 30%.
Tratamento secundário: O tratamento biológico (como o processo de lodo ativado) é utilizado para remover colóides e matéria orgânica dissolvida, atingindo uma taxa de remoção de DBO superior a 90%.
Tratamento terciário: Métodos químicos ou físicos (como coagulação, filtração e osmose reversa) são utilizados para remover poluentes como matéria orgânica recalcitrante, nitrogênio e fósforo. Produtos químicos para purificação de água (como coagulantes e desinfetantes) são normalmente utilizados na fase de tratamento terciário para purificar ainda mais a qualidade da água.
Les produits chimiques de purification de l’eau sont principalement utilisés lors de la phase de traitement tertiaire.
Le traitement des eaux usées se divise généralement en trois étapes :
Traitement primaire : Des méthodes physiques (telles que les dégrilleurs, les dessableurs et les décanteurs primaires) sont utilisées pour éliminer les matières en suspension et flottantes, atteignant un taux d’élimination de la DBO d’environ 30 %.
Traitement secondaire : Un traitement biologique (comme le procédé des boues activées) est utilisé pour éliminer les colloïdes et la matière organique dissoute, atteignant un taux d’élimination de la DBO supérieur à 90 %.
Traitement tertiaire : Des méthodes chimiques ou physiques (telles que la coagulation, la filtration et l’osmose inverse) sont utilisées pour éliminer davantage les polluants tels que la matière organique récalcitrante, l’azote et le phosphore. Des produits chimiques de purification de l’eau (tels que les coagulants et les désinfectants) sont généralement utilisés lors de la phase de traitement tertiaire pour améliorer la qualité de l’eau.
