Modular, Skid Mounted Chemical Dosing System

Modular, Skid Mounted Chemical Dosing System

Problem: A treatment plant required modular, skid mounted chemical dosing systems to accurately and reliably inject coagulant, flocculant, and peroxide into the process. The client needed a solution that combined high dosing accuracy with built in safety, while minimizing operational risk, startup time, and field installation complexity.

Because multiple chemicals were being injected at different points in the process, the system also had to protect against pulsation, pipe blockages, and overpressure events while ensuring repeatable, consistent dosing performance.

Chemical Feed Injection Pulsation

Chemical Feed Injection Pulsation

Problem: Japan Machinery Company, a manufacturer of water treatment equipment, uses air operated chemical feed pumps to inject various chemicals and additives at very high pressures. The reciprocating action of the pumps produced excessive pulsation and vibration in the discharge pipes of the system, which caused broken pipes, failed gaskets, damaged valves, and pulled pipe supports from their foundations.

Low-Viscosity Injection Pulsation

Low-Viscosity Injection Pulsation

Problem: A leading paper manufacturer located in Japan uses air operated double diaphragm (AODD) pumps to inject process chemicals into a mixing tank. The low viscosity of the liquid, less than 10 centipoises, makes the chemical in this particular application very susceptible to the reciprocating action of the pumps. This makes it extremely difficult to maintain any type of accuracy when introducing the chemical into the batch. As a result, the quality and consistency of the final product suffers.
