Polyacrylamide Water Treatment

I. Introduction to Polyacrylamide Water Treatment Products

POLYACRYLAMIDE WATER TREATMENT

 

The polyacrylamide water treatment products manufactured by Henan Saifu are high-efficiency flocculants produced using newly upgraded automated production lines and advanced processes. Capable of achieving highly efficient solid-liquid separation with extremely low dosage rates, these products significantly reduce overall water treatment costs and address critical industry pain points associated with traditional inorganic flocculants-namely, their high dosage requirements and poor treatment efficacy. Classified into three major series based on their ionic characteristics, these products cover the full spectrum of water treatment requirements; their specific parameters and characteristics are detailed below:

(1). Core Product Features

• High-Efficiency Flocculation: The polar groups present on the molecular chains rapidly adsorb suspended particles in the water. Through a combination of charge neutralization and bridging effects, they form dense, large flocs, thereby accelerating the settling rate and enhancing treatment efficiency. The resulting supernatant exhibits high clarity, and Suspended Solids (SS) levels can be reduced to below 5 mg/L.
• Broad Applicability: The product features a wide effective pH range and is compatible with various water qualities-including neutral, acidic, and alkaline conditions. Whether treating high-turbidity inorganic wastewater or wastewater with high organic content, optimal treatment results can be achieved through precise product selection.
• Energy-Efficient and Eco-Friendly: The required dosage is merely 1/50th of that of traditional inorganic flocculants, effectively reducing chemical consumption and sludge generation while lowering subsequent sludge disposal costs. Furthermore, the product causes no secondary pollution, complies with environmental discharge standards, and contains residual monomers at levels of ≤0.05%, making it suitable for use in drinking water pretreatment applications.
• Ease of Use: The product is available in the form of white granules or powder and dissolves rapidly (within ≤60 minutes). It maintains excellent stability once dissolved and can be effectively dissolved in clear water at ambient temperatures. A simple stirring speed of 60–100 rpm is sufficient, eliminating the need for complex operational procedures. For best results and to prevent degradation leading to reduced efficacy, it is recommended that the dissolved solution be utilized within 24 hours.

Note: Products featuring customized molecular weights and degrees of ionicity can be tailored to specific client requirements-including water quality, treatment processes, and compliance standards-to achieve an optimal balance between performance and cost.

II. Application Fields of Polyacrylamide Water Treatment Products

Leveraging the versatile characteristics of its products, Henan Saifu Company's polyacrylamide is widely utilized across diverse sectors-including municipal services, industry, and environmental protection. Focusing on three core requirements-"water purification, sludge reduction, and compliant discharge"-the company delivers precisely tailored solutions. Specific applications are outlined below:

(1) Municipal Wastewater Treatment
Addressing suspended solids, colloids, organic matter, and residual sludge present in municipal domestic wastewater, we provide a comprehensive, process-adapted treatment solution:

• Flocculation and Sedimentation Stage: Anionic polyacrylamide is dosed in conjunction with inorganic flocculants-such as Polyaluminum Chloride (PAC)-to rapidly remove suspended solids and turbidity from the water, reduce Chemical Oxygen Demand (COD) levels, and facilitate the efficient operation of primary and secondary sedimentation tanks.
• Sludge Dewatering Stage: Cationic polyacrylamide is dosed to destabilize sludge colloids through charge neutralization, causing sludge particles to agglomerate. Following dewatering via plate-and-frame filter presses or belt filter presses, the sludge moisture content is reduced to below 80%. This significantly lowers sludge transportation and disposal costs, thereby enabling compliance with wastewater discharge standards and achieving effective sludge volume reduction.

(2) Industrial Wastewater Treatment

Addressing the significant variations in wastewater quality across different industries, we provide precise product selection and customization to resolve a wide range of industrial wastewater treatment challenges:

• High-Turbidity Inorganic Wastewater: Wastewater generated by industries such as coal washing, mineral processing, and aggregate production is rich in inorganic suspended solids-including silt and slag. By utilizing anionic polyacrylamide, we accelerate particle sedimentation to facilitate water recycling; reuse rates can exceed 80%, thereby minimizing water resource waste. For instance, in the treatment of wastewater from phosphate mines in Guizhou, the removal rate for suspended solids exceeds 90%.
• High-Organic-Content Wastewater: Wastewater from industries such as textile dyeing and printing, food processing, and papermaking contains organic pollutants such as dyes, proteins, and fiber fragments. The application of cationic or non-ionic polyacrylamide enables effective flocculation, decolorization, and pollutant removal. This approach boosts decolorization efficiency in dyeing and printing wastewater by 60% and improves de-inking efficiency in papermaking wastewater by 30%.
• Complex Wastewater: Wastewater generated by industries such as chemical manufacturing and petroleum refining often consists of complex mixtures containing oil, acids, and alkalis. By employing non-ionic polyacrylamide-which exhibits strong acid-alkali resistance and maintains excellent stability across a pH range of 1 to 14-we can efficiently remove emulsified oils and mixed pollutants, thereby ensuring that wastewater meets regulatory discharge standards.

(3) Drinking Water and Water Supply Pretreatment

To address impurities such as algae, humic substances, and sediment found in surface water sources-including rivers and lakes-the addition of non-ionic or low-anionic polyacrylamide, used in combination with inorganic flocculants, can significantly enhance flocculation efficiency. This approach reduces the required dosage of inorganic flocculants, minimizes residual aluminum ions in the treated water, and thereby safeguards the safety of drinking water supplies. Furthermore, this method is applicable to the pretreatment of industrial circulating water and boiler feedwater, effectively removing suspended solids and colloidal particles from raw water. This prevents scaling and clogging in heat exchangers and boiler pipelines, improves water quality compliance rates, and ensures the stable and reliable operation of industrial production processes.

(4) Other Environmental Protection Fields
In addition to the core scenarios outlined above, the product can also be applied in areas such as sludge resource utilization, landfill leachate treatment, and mine wastewater remediation. By facilitating efficient flocculation and dewatering, it enables the harmless disposal of pollutants and the recycling of resources, thereby assisting enterprises in achieving green production and fulfilling their environmental responsibilities.
