Arch Chemicals, Inc. produces the new generation Constant Chlor® Plus calcium hypochlorite briquette feed systems that provide increased capacity and accuracy that exceeds its first generation system, plus new capabilities and features that further enhance operation, maintenance and safety.

The model MC-2S system retains all of the key features that made Constant Chlor® the system of choice for years, such as optimum solution consistency and a small footprint; but its loading and feed rate capacities are much higher, allowing for its effective service to larger treatment facilities. Maintaining constant residual levels is even easier with the second generation system. This model can provide up to 250 pounds per day AvCl, which means more than 10 pounds per hour of hypochlorite solution is available on demand, allowing for continuous dosing from the system's dosing tank. For applications requiring 0.5 to 3.0 lbs. AVCl per hour see the Constant Chlor® model MM-1S.

The feeder uses NSF Standard 60 listed Constant Chlor® Plus dry calcium hypochlorite briquettes and patented spray technology to produce fresh liquid chlorine solution as needed. The fresh made reservoir is filled with approximately 1.7% available chlorine solution and volume is maintained via an electronically controlled spray manifold. The hypochlorite solution is injected into the application with an appropriate, highly accurate positive displacement chemical metering pump specified for the application. Most metering pumps can be mounted directly to the pump mounting plate on the Constant Chlor® skid.

Other Features Include:

• Large hopper provides a dry chemical capacity of 220 lbs.
• Small, 14.5 sq. ft. footprint.
• Dual position controls allow for flexible installation configurations.
• Nested configuration makes it easy to disassemble for maintenance.
• Optional dilution feature allows for solution concentrations adjustments from 0.5 to 1.7 percent AvCl.
• SCADA ready low solution alarm and optional low briquette alarm.
• Convenient AvCl solution sample feature.
• Separate fill cycle switch allows maintenance without service interruption.
• Simple installation.

With Arch's new generation Constant Chlor® feed system, chlorination operations become even more effective and efficient. Most importantly, a steady, constant dose of hypochlorite disinfection solution is always there when you need it.
