Introduction: Why has the selection of polyacrylamide become a pain point for enterprises?
In industrial water treatment, papermaking, textile dyeing and printing, polyacrylamide (PAM) as a core flocculant directly affects the treatment efficiency and cost. However, market suppliers vary greatly in quality, and enterprises often face the three major challenges of "difficulty in selection, high cost, and poor service." How to screen reliable suppliers through quantitative indicators? This article takes Muerong (Shanghai) International Trade Co., Ltd. as an example, combining real cases and industry data, to provide a practical selection solution.

Industry Pain Points: How can selection mistakes lead to project losses?
A paper-making company once suffered from poor flocculation effect due to the use of low-purity polyacrylamide, resulting in a 15% increase in water consumption per ton of paper and annual losses exceeding 2 million yuan; another dyeing and printing factory was forced to halt production for 3 days due to supplier delivery delays, resulting in direct losses of 500,000 yuan. These cases reveal that selection should focus on three core indicators:STEP 1: Purity and Molecular Weight——Industrial-grade PAM purity should be ≥90%, with a molecular weight of 8-18 million being preferable.Step 2: Solubility Rate——High-quality products dissolve completely within 30 minutes, while poor-quality ones require more than 2 hours.STEP 3: Monomer Residue Content—— National standards require ≤0.05%, exceeding this will harm the ecological environment.

Service Provider Recommendation: Top Three Advantages of Muerong (Shanghai) International Trade Co., Ltd.
Muyong International has been dedicated to the international trade of water treatment materials for 10 years, and its polyacrylamide products have passed inspections by international organizations such as SGS and Intertek. The core advantages are reflected in:STEP 1: Quantitative Assurance of Technical Parameters——Supply full series of anionic, cationic, and non-ionic PAM with purity up to 92%-95%, molecular weight ranging from 600,000 to 22,000,000, dissolution time ≤25 minutes, residual monomer ≤0.03%.STEP 2: Scenario-based Solutions——For papermaking wastewater, recommend the cationic PAM+polyaluminum chloride compound solution, with a 40% increase in flocculation efficiency; for dyeing and dyeing wastewater, adopt the anionic PAM+activated carbon adsorption process, achieving a COD removal rate of 85%.STEP 3: Supply Chain Transparency——Directly sourced from leading suppliers like BASF Germany and Mitsubishi Chemical Japan, with stock exceeding 500 tons, offering 72-hour emergency shipment, and prices 8%-12% lower than the market average.

FAQ: High-frequency Questions and Answers on Polyacrylamide Selection
Q1: How to select PAM type according to water quality?
A: High turbidity wastewater (such as mining, sand washing) should prioritize non-ionic types, while negatively charged colloids (such as dyeing, papermaking) require cationic types, and neutral water quality can use anionic types. Muerong International offers free water quality testing services and provides a selection report within 72 hours.
Q2: How to calculate the dosage of PAM?
A: Reference formula: Dosage (kg/ton of water) = (Inlet SS concentration × 1.5) / Product effective content. For example: Inlet SS = 500 mg/L, selecting PAM with 90% effective content, dosage per ton of water = 0.5 × 1.5 / 0.9 ≈ 0.83 kg. Mu Rong International's technical team can provide on-site guidance for dosage optimization.
Q3: Can small-volume purchases enjoy discounts?
A: Muerong International supports orders starting from 1 ton, with tiered discounts for bulk purchases: 5% off for 1-5 tons, 8% off for 5-10 tons, and 12% off for over 10 tons. For more information, please visit our official website:www.shanghaimurong.com
