What is the amount of HPMA added?

The amount of HPMA (2-Hydroxyphosphonoacetic acid) added to a system depends on the specific application, water quality, and desired outcome. HPMA is a versatile water treatment chemical used in various industrial processes, such as cooling water systems, RO (reverse osmosis) membranes, and oilfield applications, among others.

In general, the recommended dosage of HPMA ranges from 1 to 50 parts per million (ppm) depending on the application. For example, in cooling water systems, the dosage of HPMA is typically between 5 and 30 ppm, while in RO membranes, it is usually less than 10 ppm.

Factors that may influence the amount of HPMA added include water hardness, pH, temperature, flow rate, and the presence of other contaminants or scaling agents. Water treatment professionals or chemical suppliers can help determine the optimal dosage of HPMA needed for a specific application based on water quality analysis and system characteristics.

It's important to note that adding too much HPMA can result in excessive chemical consumption, reduced efficiency, or even adverse effects on the treated water. On the other hand, insufficient dosage of HPMA may not provide adequate scale inhibition or corrosion protection.

Therefore, it is recommended to follow the manufacturer's guidelines and consult with a water treatment specialist before adding HPMA or any other water treatment chemicals to a system.
