How many PAM chemicals types for wastewater treatment?

Polyacrylamide (PAM) is classified into four types based on its ionic properties:

Anionic: Suitable for neutral/alkaline environments, with significant effects on inorganic sludge (such as sand washing wastewater).

Cationic: Used for dewatering organic sludge (such as municipal sewage), neutralizing negatively charged particles with positive charges.

Nonionic: Low molecular weight, Suitable for neutral or acidic wastewater, using hydrogen bonding for adsorption and flocculation.

Amphoteric: Contains both positive and negative charged groups, suitable for complex water qualities (such as industrial wastewater).

For so many years selling, the APAM, CPAM and NPAM are widely used, welcome to contact Rita for more details. wa.me/8617737518864

For the PAC products, is it always better to have low basicity?

Today let’s talk about something about the basicity of Polyaluminum Chloride(PAC) products. We all know, for the PAC products, basicity is also an important element in determining the final price. Then is it always better to use the low basicity PAC?

Well, basicity should be determined based on the specific application scenario; there’s no absolute “high” or “low” for best. The following are key criteria for determining effectiveness:

Application Scenario Determines Advantages and Disadvantages
Wastewater Treatment:
Highly turbid wastewater (such as printing and dyeing, and chemical wastewater) is more suitable for products with higher basicity, as they offer a more effective flocculation effect.

Using high-basicity products for low-turbidity water (such as drinking water) may cause turbidity, so a low-basicity product should be selected.

Production Cost:
Higher basicity reduces raw material consumption and reduces production costs. However, drinking water-grade products have higher environmental requirements, which can increase raw material costs.

Industry Standard Reference: The basicity of industrial-grade polyaluminum chloride is typically around 85-90%, while that of drinking water-grade products is around 45-60%.

Selection Principles
Water quality determines salinity: For high turbidity water, choose a high-basicity PAC; for low turbidity or drinking water, choose a low-basicity PAC.

Economic Considerations: High-basicity PAC offers lower costs, but a balance must be struck between effectiveness and stability.

Experimental Verification: Before practical application, the optimal salinity should be determined through pilot tests to avoid theoretical deviations.

Effuent water treatment—PAC & PAM Applied

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~

Cationic polymer for pig farm sewage disposal

Today I shared a video of the cationic PAM working in the pig farm sewage on Youtube. Hope you can give me a like. Thank you.

Poultry farm sewage is smelly, but after flocculation, the final sludge can be buried underground and finally enrich the soil. What we do is a virtuous cycle process benefit the earth. Let’s talk more.

Wastewater Treatment–Cationic polyacrylamide

By Rita +86-17737518864
Wastewater treatment demands as much attention, and the need for integrated solutions, as other processes within your operation. There are not many other processes that have so much variability in the input, yet a consistent, high quality output is requested.

Wastewater Treatment Overview
We understand that effective primary waste water treatment is critical to your plant operations, whether you are discharging directly to a municipal wastewater treatment system or treating prior to your own wastewater treatment system. Optimizing the performance of treatment chemicals and equipment can dramatically minimize overall costs and maximize your return on investment, and that’s what we can offer for you.

Solids dewatering is the second-highest cost area in a wastewater treatment plant, second only to electrical utility costs. Effectively optimizing the performance of dewatering equipment and chemicals can dramatically minimize the total cost of operation and maximize your return on investment. Our cationic polyacrylamide products with perfect performance can greatly help you dispose the sludges efficiently.

Our wastewater chemical typically focus on the following and can help you with:

  • waste water treatment
  • sludge dewatering
  • tailing ore selection
  • drilling lubricant

PAM is the trend of water treatment

Impressed by the words of Mr. Lalith Liyanage, Ph.D P.EngNational Technical Director – Wastewater, WSP in Canada:”Understanding technology and having the tools to recover valuable resources from wastewater, will empower the operators not only to protect environment, reduce environmental footprint but also make wastewater treatment more affordable and in some cases profitable.”

Like the Director said, the technology is used to recover the most valuable resource—water in this planet, that’s the meaning of the development of technology, and also the meaning of our work.

Polyacrylamide is the trend of development. Its working with PAC or PSF products can provide outstanding result in the water treatment plant. More clearer water obtained, safer and more beautiful our world will be. Let’s work together~

Indowater 2025 Expo in Jakarta—Successful


We are thrilled to reflect on an incredibly successful participation at the recent Indowater Expo in Jakarta! Our team had a wonder experience there and took the chance to visit many valued customers from across the region.

At our booth, we displayed our best selling polymers, like the cationic polyacrylamide products of different ionic degrees with very competitive price, which we’re so proud to have the compliments from clients came to our booth, also the widely used anionic polyacrylamide models, working best with the PAC products (polyaluminum chloride). Though we only have limited models of on-ionic polyacryamides, they’re all selling pretty good. The enthusiasm and interest from attendees reaffirmed the growing demand for our products in the Indonesian market.

We extend our heartfelt gratitude to everyone who visited us, shared insights, and expressed interest in our offerings. Your engagement has inspired us to continue pushing the boundaries of excellence.

While the great opportunities brought by the exhibition, we hope to meet more friends in all the other exhibitions all around the world. We are excited to follow up on the connections we made and explore new avenues for growth together. Our aim is to serve you the best suitable polyacrylamide products for water treatment and sludge dewatering for your factories. Let’s meet and talk how to protect our world–the earth.

Please kindly stay focused on our updates of the coming journey, while as we continue to bring innovative solutions to Indonesia and beyond!

PAM and PAC is the best partner:

By scientifically using the combination of PAC and PAM, we can more effectively neutralize the charge first and then bridge and flocculate, the sedimentation rate is increased several times, the sludge is easier to dewater, and the cost is reduced by 30% – an efficient golden combination for industrial wastewater treatment.

PAC can only make particles clump together, i.e. microflocs, the precipitation effect is slow and the water is still turbid. While PAM, its adsorption bridging is the key, linear property is like a large net to capture precipitation into large and dense flocs and accelerate sedimentation.
