I. Introduction The textile printing and dyeing industry is a vital sector of China’s economy, yet it is also a major consumer of water and a significant source of pollution. Statistics show that traditional dyeing processes consume approximately 200 liters of water per kilogram of fabric produced. The wastewater generated contains large quantities of dyes, auxiliaries, heavy metals, and organic solvents, making treatment difficult and costly. Against the backdrop of increasingly stringent environmental regulations and intensifying market competition, achieving a balance between efficient production and environmental protection has become a critical challenge for textile dyeing enterprises. Polyacrylamide (PAM), as a water-soluble high-molecular polymer, has seen its applications in the textile printing and dyeing industry expand from traditional wastewater treatment to sizing, printing, dyeing, and finishing processes, thanks to its excellent flocculation, thickening, and adhesion properties. Henan Secco Environmental Technology Co., Ltd., a professional supplier of wastewater treatment chemicals specializing in polyacrylamide, polyaluminum chloride, and polyferric sulfate, is committed to providing efficient and environmentally friendly chemical solutions for the dyeing industry. II. Applications of Polyacrylamide in Pre-treatment and Dyeing Processes 1. As a Leveling Agent to Improve Dyeing Uniformity During immersion and pad dyeing processes, dye migration on fabrics is often uneven, particularly during...

Against the background of tightening global environmental policies and the paper industry’s transformation towards a green, low‑carbon future, how to efficiently utilise resources, reduce production costs and ensure compliant wastewater discharge has become a core challenge for many paper enterprises. Among various solutions, polyacrylamide (PAM) – with its excellent flocculation, sedimentation, thickening and strengthening properties – has evolved from a simple “auxiliary additive” into an indispensable processing aid and a key element for process control in modern papermaking. As a high‑tech enterprise based in Gongyi City (a renowned national industrial cluster for water treatment chemicals), Henan Secco Environmental Protection Technology Co., Ltd. specialises in the R&D, production and sale of water treatment chemicals. We operate a modern production line with an annual capacity of 50,000 tonnes of polyacrylamide, offering cationic, anionic and non‑ionic polymer flocculants. For the paper industry, our products can be customised according to different pulp characteristics, machine speeds and environmental requirements, providing paper mills with precise, high‑efficiency papermaking aid solutions. 1. Retention & Drainage Aid: Improving Paper Machine Efficiency and Saving Raw Materials During the wet‑end of papermaking, fine fibres and expensive fillers (e.g. calcium carbonate, titanium dioxide) are easily lost with the white water. As a highly efficient retention and drainage...

There is no one‑size‑fits‑all answer in wastewater treatment, but there is a more efficient path to results. Stop taking detours through guesswork. Start finding the truth through testing. Contact Henan Secco Environmental Technology Co., Ltd. today to get your customized flocculation solution.

In wastewater treatment, flocculation and sedimentation are among the most common and critical steps. However, many users initially tend to use only one type of flocculant — most often polyacrylamide (PAM). But does using PAM alone truly achieve ideal purification results?

In wastewater treatment and sludge dewatering processes, Polyacrylamide (PAM) plays a critical role as a flocculant. Its dissolution efficiency, flocculation performance, and compatibility with dewatering equipment directly determine treatment effectiveness and effluent quality.

Polyacrylamide (PAM) has long been known as a "versatile industry aid," playing an indispensable role in water treatment, oil extraction, papermaking, and many other fields. As one of the core products of Henan secco Environmental Protection Technology Co., Ltd., polyacrylamide has demonstrated strong technical strength and market value in conventional wastewater treatment thanks to its excellent flocculation, adhesion, thickening, and drag reduction properties.

When PAM powder contacts water, its surface quickly swells and forms a gel layer, blocking further water penetration and resulting in semi‑transparent, gel‑like particles ("fish eyes"). These not only waste chemicals but also clog dosing pumps and pipelines, affecting system stability.

From April 13 to 15, 2026, the 27th Shanghai International Environmental Protection Expo (IE expo Shanghai 2026) was grandly held at the Shanghai New International Expo Centre. As one of the most influential professional environmental protection events in Asia, this year’s expo, themed “Connecting Global Opportunities, Exploring Emerging Drivers,” took place at a pivotal moment — the first year of the “15th Five-Year Plan” period.

From April 9 to April 10, 2026, Henan SECCO Environmental Protection Technology Co., Ltd. — a company specializing in wastewater flocculation and sedimentation chemicals such as polyacrylamide, polyaluminum chloride, and polyferric sulfate — organized a two-day outdoor training event at the scenic Songhuang Sports Town in Dengfeng

When dealing with wastewater, polyacrylamide (PAM) and polyaluminium chloride (PAC) are commonly used as coagulants and flocculants to remove suspended solids, color and other pollutants from the wastewater. The following are the basic operation steps for using these two chemicals.
