Selecting the most appropriate coagulant is a critical decision for any water treatment facility. While Aluminum Sulfate (Alum) has been a long-standing staple, advancements in chemical technology have introduced more efficient alternatives like Aluminum Chlorohydrate (ACH). This article provides a comparative analysis to help procurement managers and R&D scientists make an informed choice. As a leading supplier, we offer insights into the performance benefits of ACH.

Aluminum Sulfate, commonly known as alum, is a traditional inorganic coagulant widely used for decades. It functions by neutralizing the negative charges on suspended particles, causing them to destabilize and aggregate into larger flocs. However, alum has certain limitations that ACH effectively addresses. For instance, alum can lead to significant pH depression, often requiring substantial alkali additions to maintain optimal treatment conditions. This increases operational costs and complexity.

Aluminum Chlorohydrate (ACH), on the other hand, is a pre-polymerized aluminum salt with a higher basicity and charge density. This structural advantage allows ACH to perform more efficiently at lower dosages compared to alum. Studies and practical applications consistently show that ACH requires approximately one-third of the dosage needed for liquid alum to achieve similar or superior results in turbidity removal and flocculation.

The impact on sludge generation is another key differentiator. Alum usage typically results in higher volumes of chemical sludge, which incurs significant costs for dewatering and disposal. ACH, due to its higher efficiency and cleaner reaction, generates considerably less sludge. This not only reduces disposal expenses but also minimizes the environmental footprint of the treatment process. If you are looking to buy ACH and reduce your sludge management costs, consider our offerings.

Furthermore, ACH's high basicity means it has a much milder effect on water alkalinity and pH compared to alum. This often eliminates the need for secondary alkali addition, leading to a more stable process and reduced chemical consumption. This factor alone can lead to substantial cost savings for treatment plants. For procurement managers seeking to buy high-performance coagulants, ACH presents a compelling case for upgrading.

While the initial purchase price of ACH might sometimes appear higher per unit volume than alum, the overall cost-effectiveness becomes evident when considering the lower dosage rates, reduced chemical additive requirements, and minimized sludge disposal fees.
