The selection of a primary coagulant is a critical decision in water treatment, directly impacting treatment efficiency, operational costs, and the quality of the final treated water. Among the widely used options are Aluminum Chlorohydrate (ACH) and Polyaluminum Chloride (PAC). While both are effective inorganic polymer coagulants, understanding their distinct characteristics is vital for making an informed choice. As a dedicated supplier of high-performance chemicals, we aim to shed light on why ACH often emerges as the superior solution, particularly for demanding applications.

The fundamental difference between ACH and PAC lies in their chemical structure, specifically their aluminum concentration and basicity. Aluminum Chlorohydrate generally possesses a higher aluminum concentration (Al2O3) and a significantly higher basicity compared to most PAC products. Basicity, in essence, refers to the degree of neutralization of the hydrochloric acid within the molecule. A higher basicity in ACH means it has a greater positive charge density. This enhanced cationic charge is the key to its superior performance.

How does this translate to practical advantages? Firstly, the higher charge density of ACH allows it to neutralize negative charges on suspended particles and impurities more effectively, even at lower dosages. This reduction in required dosage directly impacts cost savings, as less chemical is consumed per unit of water treated. It also means reduced transportation and storage volumes, further optimizing operational expenses. For procurement managers looking to buy Aluminum Chlorohydrate, these dosage efficiencies are a major selling point when comparing with PAC suppliers.

Secondly, ACH's higher basicity leads to a minimal impact on the water's pH. Traditional coagulants, including many PAC formulations, can significantly lower pH, necessitating the addition of alkaline chemicals to adjust it. This adds complexity and cost to the treatment process. ACH, conversely, often requires little to no pH adjustment, simplifying operations and reducing chemical reliance. This makes ACH particularly attractive for facilities dealing with low-alkalinity source waters.

Furthermore, ACH tends to form denser, more compact flocs than PAC. These robust flocs are easier to settle and dewater, resulting in a lower sludge volume. Reduced sludge means lower disposal costs and a more streamlined waste management process. This is a critical consideration for water treatment plants aiming to improve their environmental footprint and manage operational expenses efficiently. When seeking a reliable Aluminum Chlorohydrate manufacturer in China, these factors of sludge reduction and ease of handling are paramount.

While PAC remains a viable coagulant for many applications, ACH's advanced properties—higher efficiency at lower doses, wider pH operating range, minimal pH impact, and reduced sludge production—often give it an edge, especially in challenging water conditions or when aiming for the highest quality effluent. Whether you are sourcing for drinking water treatment, industrial wastewater, or specialized applications, understanding these distinctions will guide you towards the most effective and economical choice.
