pH Control System uses CO2 and gas injectors.

February 18, 2015

Suitable for treating very high flows in pipelines, large tanks, or treatment ponds, Model 5000B features external manifolds with Dif-Jet™ gas injectors that inject CO2 directly into circulating wastewater to lower pH. Non-fouling gas injectors do not produce back pressure over time and will last indefinitely. Powered by submersible pump, Model 5000B is controlled by PLC that is programmed to feed CO2 at certain trip point and automatically cut off CO2 feed once target pH is achieved. Read More

Portable pH Control System can eliminate hazardous acids.

September 20, 2011

Able to treat up to 2,700 gph of process water, Model 5000SP uses safe CO2 gas to lower pH and can be equipped with peristaltic chemical feed pump to inject alkaline solutions to raise pH. Design uses owner-furnished tanks, basins, lagoons, or sumps and does not require mixer in treatment tank. Depending on water quality required prior to discharge, onboard cartridge filter may be used with or without 3 micron filter cartridge. This 39 x 24 x 39 in. system suits mobile/fixed operations.

Portable pH Control System targets concrete processing industry.

February 28, 2011

Poli-Cut pH control system lowers pH of process water produced in concrete polishing, grinding, and cutting operations so that water can be safely discharged without polluting environment. Self-contained, automated machine utilizes CO2 gas that is diffused and injected into wastewater to lower pH to 7.0. Mounted on 5 in. polyurethane swivel casters, product has 200 gal tank with 2 in. bottom drain; 2-speed pump, and is able to treat 1,500-3,000 gph. Read More
