When selecting coagulants for water and wastewater treatment, making an informed decision between different chemical options is crucial for both performance and budgetary reasons. Aluminium Chlorohydrate (ACH) and Alum (Aluminum Sulfate) are two widely used inorganic coagulants, but they offer distinct advantages. For procurement managers and plant operators, understanding these differences is key to optimizing treatment processes and controlling costs. NINGBO INNO PHARMCHEM CO.,LTD., as a premier manufacturer and supplier, offers insights into why ACH is increasingly preferred.

One of the primary differentiators lies in their chemical structure and performance characteristics. Alum is a traditional coagulant, effective but often requires higher dosages and is more sensitive to pH variations. Aluminium Chlorohydrate, on the other hand, is a highly polymerized inorganic salt with a significantly higher basicity and alumina content. This advanced structure allows ACH to achieve better flocculation and particle removal at lower doses compared to alum. For buyers looking to purchase chemicals, lower dosage requirements directly translate to reduced consumption and savings.

The impact on sludge production is another critical consideration. Alum treatment can generate a large volume of gelatinous sludge, which is often difficult to dewater and expensive to dispose of. ACH, due to its more efficient coagulation mechanism, typically produces less sludge, and the sludge generated is often denser and dewaters more readily. This reduction in sludge volume can lead to substantial savings in sludge handling and disposal costs, a significant factor for any plant manager focused on operational efficiency.

pH stability is also a key area where ACH excels. Alum tends to lower the pH of treated water, often necessitating the addition of alkali to maintain optimal pH levels, adding another chemical cost and process step. ACH's high basicity means it has a much lower impact on pH, often reducing or eliminating the need for alkali addition. This simplifies the treatment process and further contributes to cost savings for those looking to buy treatment chemicals.

In terms of application versatility, ACH often demonstrates superior performance in cold water conditions and across a broader pH range than alum. This makes it a more reliable choice for facilities experiencing variable water temperatures or raw water pH. For industries such as papermaking or cosmetics, where specific performance attributes are critical, ACH's nuanced capabilities can offer distinct advantages over traditional alum.

When considering a switch or an upgrade, purchasing managers should consult with reputable suppliers. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Aluminium Chlorohydrate, offering a cost-effective and performance-enhanced alternative to alum. We encourage you to request a quote and discuss your specific needs to understand how ACH can optimize your water treatment processes and reduce your overall chemical expenditure. Choosing the right coagulant is a strategic decision, and ACH often represents the superior choice for modern facilities.
