Henan Wanzhong Water Treatment Co., Ltd., a leading manufacturer and exporter of high-performance water treatment chemicals, successfully participated in the 23rd China Animal Husbandry Expo (CAHE), held from May 18 to May 20, 2026. As a premier event for the global livestock industry, the expo provided an ideal platform for the company to showcase its flagship products—Polyacrylamide (PAM) and Polyaluminum Chloride (PAC)—and their critical applications in livestock wastewater treatment.
With the rapid expansion of intensive animal farming, effective management of manure and process water has become a global priority. Henan Wanzhong’s exhibit focused on how its chemical solutions meet these challenges head-on, offering both environmental compliance and operational efficiency.
At the heart of the company’s display were their roles as essential coagulants and flocculants in treating high-strength livestock effluent.
1. Polyaluminum Chloride (PAC) as a Superior Coagulant
Livestock wastewater—from swine, poultry, and cattle operations—contains high concentrations of suspended solids, colloids, and organic matter. Henan Wanzhong’s high-basicity PAC serves as an advanced coagulant, rapidly neutralizing the negative charges of fine particles. This initiates the formation of micro-flocs, effectively reducing turbidity, Chemical Oxygen Demand (COD), and Total Phosphorus (TP) in primary treatment stages.
2. Polyacrylamide (PAM) for Flocculation & Sludge Dewatering
The star of the booth was the company’s range of Polyacrylamide (PAM) , particularly anionic and nonionic grades optimized for animal waste. As a high-molecular-weight flocculant, PAM bridges the micro-flocs created by PAC into large, dense aggregates that settle rapidly. This process is crucial for solid-liquid separation in lagoon systems and mechanical separators.
Beyond clarification, PAM plays an indispensable role in sludge dewatering. Livestock farms produce voluminous, watery sludge that is costly to store and transport. By applying the correct PAM formulation, Henan Wanzhong’s technology significantly increases the efficiency of belt presses, centrifuges, and screw presses. The result is a drier, cake-like sludge that is easier to handle, reduces disposal costs, and can even be repurposed as organic fertilizer.
“We were thrilled with the engagement at CAHE 2026,” said a company spokesperson. “Many large-scale farm operators and system integrators approached us seeking cost-effective yet reliable solutions for their challenging wastewater. By combining our Polyaluminum Chloride as a primary coagulant and Polyacrylamide for enhanced flocculation and sludge dewatering, we provide a complete chemical package that lowers overall treatment costs while meeting strict discharge or reuse standards.”
As an established exporter, Henan Wanzhong emphasized its rigorous quality control, consistent product performance, and customized technical support for international clients. The company’s chemicals are widely used not only in animal husbandry but also in municipal, mining, and industrial wastewater treatment worldwide.
The 23rd CAHE provided Henan Wanzhong with valuable opportunities to strengthen existing partnerships and forge new ones. With global demand for sustainable livestock farming on the rise, the company reaffirmed its commitment to advancing water treatment chemistry that enables cleaner production, resource recovery, and environmental stewardship.
