When should we use Water purification chemicals (PAM+PAC) in water treatment?

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.

PAFC—-polyaluminium ferric chloride

Today let’s talk about the new wastewater treatment chemical: PAFC. It’s full name is polyaluminium ferric chloride, an inorganic polymer coagulant, used in water treatment and purification.

Composition and Structure
PAFC is a composite of aluminum and iron salts, combining the advantages of both, improving coagulation performance through synergistic synergy. Its molecular formula is [Al₂(OH)ₙCl₆-ₙLₘ], where m represents the degree of polymerization and n represents the neutrality of the product.

Key Features
Highly Efficient Coagulation: It exhibits a high degree of electrical neutralization and bridging effects on colloids and particulates in water, effectively removing micro-toxic substances and heavy metal ions.

Wide Application: It is particularly suitable for treating high-turbidity water and low-temperature, low-turbidity water, without the need for additional alkaline additives or coagulants.

Safety: As an inorganic polymer, it is non-toxic and non-polluting, meeting environmental requirements. ‌

Application Scenarios
Mainly used for drinking water purification, industrial wastewater (such as printing and dyeing wastewater and oily wastewater), municipal sewage, and special water treatment (such as removing pollutants such as cadmium and fluoride). ‌

Cationic polyacrylamide for industrial wastewater treatment

Here we’d like to share a video of acidic wastewater treatment in industrial field. We have anionic polyacrylamide, cationic polymer and non-ionic polymer for different water treatment. For more details, hope you can contact me by email rita@xinqipolymer.com or Whatsapp +86-17737518864.

Today we’ll dispose an industrial wastewater. First let’s check the PH value, now we see it’s around PH3-4, acid. So now we add sodium hydroxide to neutralize. And then we add PAC to coagulate the particles. Finally CPAM is added. And the flocs will seperate in the water and we can get the cleaner water for next step.

Wastewater treatment doesn’t only need anionic polyacrylamide. For different application, we have different polymers for your application. We can send samples for your testing or the waste water can be sent to China to be tested in our lab, if you’re not too far from China.
Welcome to contact Rita for more details.

Technical Comparison of Polyacrylamide Sample Performance​

Thanks for our client’s trust, they send their present polyacrylamide sample to us for a comparison test. We would like to provide a clear, technical explanation of the observable differences between the two products, which we believe highlights the superior quality and reliability of our offering.

​​Key Observations from the Dissolution Test:​​

  1. 1.​​Viscosity:​​
    • •​​Our Product:​​ Exhibits a characteristically ​​high viscosity​​. This is a direct indicator of a high effective polymer chain elongation in solution. High molecular weight is crucial for optimal performance in applications such as flocculation, sedimentation, and dewatering, as it creates a stronger network to capture and pull down solids.
    • •​​Client’s Sample:​​ Shows ​​significantly lower viscosity​​. This suggests a lower molecular weight, which can result in reduced efficiency and higher dosage requirements to achieve the same effect, ultimately affecting your operational costs.
  2. 2.​​Solubility & Residue:​​
    • •​​Our Product:​​ Dissolves completely, leaving ​​no visible residue​​ in the beaker. This demonstrates a high purity level and excellent solubility. Complete dissolution ensures that 100% of the product is active and contributing to the process, preventing clogging of filters and injection systems.
    • •​​Client’s Sample:​​ Leaves a ​​significant amount of insoluble residue​​ at the bottom of the beaker. This residue typically consists of cross-linked polymer (gel balls), impurities, or filler materials. These inactive components represent wasted product, can cause blockages in equipment, and reduce the overall efficiency of your process.

​​What This Means for Your Operations:​​

The differences observed are not minor; they are fundamental to the product’s quality and manufacturing process.

  • •​​Our high viscosity and complete solubility​​ are the result of advanced polymerization technology and a strict quality control process that ensures a consistent, high-purity product with a well-defined molecular structure.
  • •The ​​low viscosity and high residue​​ in the other sample often indicate one or more of the following: the use of lower-grade raw materials, less controlled manufacturing conditions, or the intentional addition of inert fillers (e.g., salts) to increase product weight. This is a common cost-cutting measure that directly compromises performance.

​​Conclusion:​​

Our product is engineered for maximum efficiency and reliability, ensuring you get full value from every kilogram purchased. The complete dissolution means no product waste and a lower risk of operational issues, while the high viscosity guarantees effective performance at optimal dosage rates.

We are confident that a full-scale trial will demonstrate not only the superior performance of our polyacrylamide but also the potential for process improvement and cost savings for your company.

We are ready to discuss these findings further and arrange the next steps at your convenience.

Plywood factories often use polyacrylamide (PAM) to treat wastewater, primarily for flocculation. ‌

Specific Functions
PAM reduces the surface potential of suspended solids by compressing the double layer, promoting particle aggregation to form flocs, and accelerating sedimentation and separation of pollutants. The acyl groups on its molecular chain can form bridges with suspended particles, significantly enhancing flocculation. ‌

Application Scenarios
Plywood production wastewater often contains organic contaminants such as lignin and adhesive residues, as well as suspended solids. PAM can effectively remove these impurities and improve water quality. ‌

Precautions
Select the type of PAM (e.g., anionic, cationic, or nonionic) based on the wastewater composition. Avoid adding dry powder directly; it is recommended to first dissolve it in a 0.1%-0.3% aqueous solution. ‌

* Temperature and pH may affect performance* therefore, it is recommended to determine the optimal dosage through experimentation. ‌

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~

Still looking for low cost but efficient waste water treatment methods?

Please contact Rita for more details. Many specs for option. Free sample for testing. Welcome to visit our factory in Gongyi, Zhengzhou city, Henan Province, China.

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.
