Today, February 26, 2026 (the 10th day of the 1st lunar month in the Year of the Horse), we have officially concluded our Spring Festival holiday and fully resumed work! In this vibrant and energetic early spring season, the Henan SECCO Environmental Protection team is ready and eager to embark on a new year's journey with full enthusiasm and professional service.

As the bell of the Chinese New Year is about to ring in 2026, I would like to extend, on behalf of all the staff at Henan SECCOEnvironmental Protection Technology Co., Ltd., our sincerest festive greetings and best wishes for the Lunar New Year!

Fish cannery wastewater is a typical high-concentration, high-turbidity, and poorly biodegradable organic effluent from food processing. Traditional physical sedimentation methods are inefficient, while direct biological treatment is overloaded. As a high-performance polymeric flocculant, polyacrylamide plays the central role of a "scavenger" and "accelerator" in this process.

The Complete Guide to Polyacrylamide Selection for Piling Slurry Treatment Struggling with efficient piling slurry treatment? The right polyacrylamide (PAM) flocculant can transform your process—enhancing dewatering efficiency, cutting disposal costs, and ensuring environmental compliance. This guide provides a professional framework for selection, helping you make informed decisions for your construction or drilling projects. Why PAM Selection is Critical Piling slurry from bored piles and foundation drilling varies widely based on geology—clay, silt, sand, or mixed soils—each demanding a tailored chemical approach. The correct flocculant delivers: Rapid solid-liquid separation Clear water recovery for reuse Dense, stable sludge cakes for easy disposal Lower overall treatment costs Key Selection Factors 1. Ionic Type: The Primary Decision Cationic PAM (CPAM): Often the most effective. Neutralizes negatively charged clay and organic particles via electrostatic attraction, destabilizing colloids. Anionic PAM (APAM): Suitable for sand-dominated slurries or when used after inorganic coagulants (e.g., aluminum salts). Functions mainly through polymer bridging. Non-ionic PAM (NPAM): Useful in highly acidic or alkaline conditions due to pH tolerance. Recommendation: Start testing with medium-to-high cationicity PAM (40–60%), especially for clay-rich, viscous slurries. 2. Molecular Weight: Influencing Floc Size & Settling Speed High (>15 million): Forms large, strong flocs that settle quickly—ideal for rapid dewatering....

Poly Aluminium Chloride (PAC) is an inorganic polymeric coagulant produced through the controlled reaction of aluminium compounds with hydrochloric acid. Known for its high cationic charge and polymeric structure, PAC is exceptionally effective in destabilizing and aggregating suspended particles in water.

Polyacrylamide (PAM) is a high-molecular-weight synthetic polymer widely used as a flocculant in water and wastewater treatment. Its primary role is to significantly accelerate the separation of solids from liquids, enhancing process efficiency across various applications.

Have you ever wondered how murky river water transforms into the clear liquid that flows from your tap? Or how wastewater treatment plants remove invisible contaminants before releasing water back into the environment? The answer lies in two fundamental processes: coagulationand flocculation.

As the seasons turn and a new chapter begins, on the occasion of the approaching New Year's Day of 2026, all staff of Henan SECCO Environmental Protection Technology Co., Ltd.extend our most sincere gratitude and warmest wishes to our valued clients and partners for your enduring trust and support.

As the year draws to a close and the world embraces the warmth, gratitude, and hope of the holiday season, I would like to extend the sincerest festive greetings from all of us at SECCOEnvironmental Technology Co., Ltd. in Henan, China. May this Christmas and the coming New Year bring you and your loved ones peace, joy, and abundant moments of togetherness.

Polyacrylamide (PAM) and Polyaluminum Chloride (PAC) are two crucial chemicals widely used in steel plant wastewater treatment. They work synergistically through different mechanisms to achieve efficient wastewater purification. As a leading manufacturer of water treatment chemicals, Henan Secco Environmental Technology Co., Ltd. (Secco) specializes in producing high-quality PAM and PAC, providing effective solutions for industrial wastewater challenges.
