NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present a case study demonstrating the tangible impact of Polyaluminium Chloride (PAC) on industrial operations, specifically within the challenging environment of a paper mill's effluent treatment. Paper production generates complex wastewater streams that require robust chemical solutions for effective purification. This study highlights how PAC provided a superior alternative to previous treatment methods.

A mid-sized paper manufacturing facility was experiencing difficulties in meeting stringent discharge limits for its wastewater. The existing treatment system, which relied on a combination of traditional coagulants and pH adjusters, struggled with inconsistent performance, high sludge volumes, and incomplete removal of suspended solids and dissolved organic matter. This led to increased operational costs, regulatory compliance issues, and environmental concerns.

The facility decided to trial Polyaluminium Chloride (PAC) as a replacement coagulant. Extensive jar testing was conducted to determine the optimal PAC grade and dosage for their specific effluent characteristics. The wastewater sample was analyzed for turbidity, pH, color, suspended solids, and Chemical Oxygen Demand (COD). Based on these analyses, a medium-basicity PAC product was selected.

Following the successful jar tests, PAC was integrated into the plant's effluent treatment system. The results were remarkable. Within weeks, the plant observed a significant improvement in effluent quality. Turbidity levels dropped dramatically, and the water became visibly clearer. The removal of suspended solids and COD exceeded the performance of the previous coagulant, allowing the plant to consistently meet and even surpass discharge regulations. This demonstrates the efficacy of PAC as a powerful industrial water treatment chemical.

One of the most immediate benefits noted was the reduction in sludge. The volume of sludge generated was approximately 25% less when using PAC compared to the previous treatment. This reduction translated into lower sludge dewatering and disposal costs, directly impacting the plant's operational budget. The denser, more compact nature of the flocs formed by PAC contributed to this significant reduction.

Furthermore, the PAC treatment required fewer adjustments to pH, simplifying the overall treatment process and reducing the consumption of additional chemicals. This streamlined approach not only saved costs but also reduced the overall chemical load in the treated water, aligning with more sustainable practices. The consistent performance of PAC, even with fluctuations in incoming wastewater quality, provided greater operational stability.

NINGBO INNO PHARMCHEM CO.,LTD. supported the paper mill throughout the transition, providing technical expertise and ensuring a seamless integration of PAC into their existing infrastructure. The success of this implementation underscores the value of Polyaluminium Chloride in addressing complex industrial wastewater challenges. For industries looking to optimize their water treatment processes, understanding the specific uses of polyaluminium chloride in water treatment can lead to substantial improvements.

This case study exemplifies how investing in advanced chemical solutions like PAC can yield significant operational and environmental advantages. For any organization seeking to improve its effluent treatment, NINGBO INNO PHARMCHEM CO.,LTD. offers expert advice on selecting the appropriate PAC grade and determining the correct polyaluminium chloride dosage for sewage and industrial applications. When evaluating the polyaluminium chloride price, it is crucial to consider the holistic benefits, including reduced sludge, lower chemical usage, and improved compliance.
