ARTICLES AND REVIEWS
Reservoir Overcomes Toxic Algae Issue
A Nebraska reservoir was experiencing toxic algae in its water. Constructed by the U.S. Army Corps of Engineers (COE) primarily as a flood control reservoir with recreation and irrigation as secondary uses, the reservoir has a surface area of 700+ acres with an average depth of almost 12 feet.
Targeted Algal Management Plan To Address Taste And Odor Problem
Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.
Microcystin Concentrations Following Treatments Of Harmful Algal Blooms
Microcystin producing cyanobacteria blooms were sampled and tested from an Illinois reservoir, an Ohio reservoir and a Michigan lake.
On-Site Chlorine Generation: The Answer For This Reuse System
By making hypochlorite solution only as needed, the compact Constant Chlor unit brings efficiency, consistency to water reuse system.
Meeting The Exacting Requirements Of Potable Water Chlorination
Constant Chlor® Plus calcium hypochlorite briquettes and new spray technology are prompting many utilities to re-evaluate their chlorination strategies. By Dave Stark
Customized Calcium Hypochlorite System Steps Up To The Challenge
Rainbow Water District has 2,400 service connections serving approximately 6,400 customers in the unincorporated portion of Springfield, OR. The district, approximately 100 miles south of Portland, is served by excellent quality groundwater from 10 wells at four well fields near the McKenzie River.
ABOUT ARCH CHEMICALS, INC.
Arch Chemicals, Inc., a Lonza company, 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 MC4-150 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 features an HMI with touch screen for easier functionality.
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 225 lbs.
- Unit is pre-plumed and skid mounted for simple installation
- All external parts make for easy PM.
- Comes with secondary containment skid
- Convenient AvCl solution sample feature.
- Automatic solution tank refill
- Separate fill cycle switch allows maintenance without service interruption.
With our 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.
