In the sectors of industrial wastewater treatment, municipal drinking water purification, and specialized separation, polyacrylamide (PAM) serves as an irreplaceable core flocculant. For industry entrants, the selection of high-quality suppliers and mastery of core technical specifications are key determinants of project success.

I. Core Functions of Polyacrylamide in the Water Purification Sector
1. Efficient Flocculation: 90% Reduction in Suspended Solids
Via its long-chain molecular structure, polyacrylamide adsorbs colloidal particles in water to form large-volume flocs. Taking a municipal water treatment plant as a case study, after adopting the cationic PAM provided by Taobo Water Purification, effluent turbidity decreased from 15 NTU to below 2 NTU, while chemical dosage was reduced by 30%.
2. Superior Adaptability to Complex Water Quality
For specialized application scenarios such as high-chroma dyeing wastewater and oily mechanical processing wastewater, our company's composite PAM products can simultaneously remove COD, heavy metals and emulsified oil, with treatment efficiency 2-3 times higher than that of conventional products.
3. Cost Optimization Performance
Through molecular weight customization technology, HiFar Chem helped a chemical industrial park reduce the treatment cost per ton of wastewater from 8.2 RMB to 5.6 RMB, cutting annual chemical expenditure by more than 2 million RMB.

II. Industry Benchmark: Technological Breakthroughs of HiFar Chem
1. Precise Molecular Weight Control Technology
The R&D laboratory of HiFar Chem adopts a low-temperature polymerization process, which enables the production of customized PAM products with molecular weights ranging from 5 million to 25 million. In a landfill leachate treatment project, its 18 million molecular weight anionic PAM restored membrane flux to 92%, far outperforming the industry average.
2. Integration of an Intelligent Dosing System
The companion-developed PAM automatic dissolution device addresses the concentration fluctuation issue associated with conventional manual dosing via dual-parameter feedback control based on pH value and flow rate. Field applications demonstrate that this system improves drug utilization efficiency by 15% to 20%.

III. Selection Pitfall Avoidance Guide: Three Core Indicators
Ion type matching: Cationic (positively charged), anionic (negatively charged), or non-ionic PAM should be selected based on the zeta potential of the target water. Incorrect ion type selection will result in ineffective flocculation.
Molecular weight compatibility: Low-molecular-weight PAM (below 5 million Da) is suitable for applications requiring rapid sedimentation, while high-molecular-weight PAM (above 15 million Da) is applicable to high-viscosity wastewater treatment.
Solubility verification: High-quality polyacrylamide products can be completely dissolved within 30 minutes; undissolved residual particulates may induce pipeline blockage. HiFar Chem offers free sample testing services for customers.

Summary: Industry Transformation Driven by Technological Innovation
With increasingly stringent environmental protection regulations, the application of polyacrylamide is evolving from simple flocculation treatment toward functionalization and intelligence. HiFar Chem maintains continuous technological innovation: it not only retains a leading position in conventional water purification, but also achieves technological breakthroughs in emerging application scenarios including new energy battery wastewater treatment and semiconductor ultrapure water production. For new entrants to the industry, selecting a supplier with customized R&D capabilities and full-process technical support is the key to realizing efficient project implementation.
