Water Treatment - Municipal

Until recently, gas chlorination has been considered the most effective method of municipal water treatment. However, many water treatment facilities cannot afford the initial capital investment, nor the ongoing operational expenses required to meet safety regulations.

Facilities that have made the transition to using sodium hypochlorite have had a number of challenges. Electric injectors, which are designed to feed a measured amount of aqueous chlorine over time, are not directly proportional to water flow. This can create problems when water flows vary or even stop, risking massive over- or under-injection of chlorine. Adjustment to the feed rate is typically accomplished using preset output levels, which makes precise adjustment difficult when you are trying to achieve a very low residual PPM level. Additionally, these injectors are not designed to effectively feed aqueous chorine in lower water flow situations typical in smaller water treatment systems.

I was a little concerned when I first saw the "Blue Chemical Injector Ball" and wondered just how well it would perform and last. We'll I'm here to tell you, it's the best chlorine injector we have ever used. We use the CP33 injector at our 200,000 gpd water plant at Lake Fairways. We have found this CP33 is easier to use, operator friendly, repair friendly and cost friendly.

Since we purchased the first one we have purchased 2 more. One is used to pump thick polymer to sludge thickening drum at North Ft. Myers Utility Sewer Treatment Plant. We have had no problems and the employees are very impressed with it's simple dosage regulator and reliability. The second injector is stored as a backup, but after two and half years we have had no need to place it in action.

Chemilizer injectors utilize a water-driven motor with an efficient, reliable diaphragm design. Because the motor is powered by the water flow, the injector easily adjusts to changes in the water flow. The sodium hypochlorite is injected into the water flow by a highly accurate positive-displacement pump.

The chemical feed is simply adjusted via the easy-to-read injection control panel on the front of the injector. The injection control panel is a flow-control calibrated to the feed-volume of the pump; adjustment to the injection control panel changes the volume of water flow through the motor providing flexible, dynamic control of the chemical feed, and resultant chlorine residual.

Use Chemilizer injectors to inject coagulants/flocculants and pH control agents

Waste Water Treatment

The treatment of wastewater is receiving increased scrutiny due to ongoing environmental concerns, and the need for alternatives in face of escalating demand on water resources.  Many municipalities have instituted or are developing plans for reuse of “gray water” for irrigation and other applications, resulting in pressure on water utilities to produce a saleable reclaimed water product.

Use Chemilizer injectors for a variety of wastewater treatment processes:

• Inject sodium hypochlorite for disinfection during final treatment
• Inject coagulants/flocculants for removal of phosphorus
• Inject potassium permanganate solution for odor control of primary sludges
• Inject polymers for thickening of sludges
• Inject sulfite or bisulfite solutions for chlorine neutralization before discharge

Water Line Treatment

Many municipalities are looking at their ageing infrastructures and considering alternatives to replacement - from biofilm and scale removal to complete rehabilitation of water mains. Many standard treatments, i.e. flushing or “pigging”, only provide a temporary solution.
