Portable monitoring

ATI's new portable Series PQ45 answers the need for a field-deployable monitor capable of measuring and recording water quality data in a variety of operating environments. It is ideal for short-term recording of specific parameters such as Free Chlorine in potable water. The systems are available for monitoring various components in water. The available measurements are dissolved oxygen, free & combined residual chlorine, dissolved ozone, residual chlorine dioxide, conductivity and pH or ORP. Each PQ45 system is supplied ready to use for the parameter specified. If systems are to be used for free or combined chlorine, dissolved ozone, or chlorine dioxide, a second measurement of pH can be added to the system.

UV disinfection

The Barrier® Sunlight V series of UV disinfection systems from Siemens Water Technologies are compact, vertically oriented modules that offer unlimited application flexibility with reduced operation and maintenance costs. The staggered lamp array offers built-in redundancy, ensuring maximum transmittance of UV radiation to the wastewater to help achieve disinfection requirements. The design also simplifies routine maintenance. Electronic ballasts and automatic flow-pacing optimize energy consumption and extend lamp life which reduce operating costs.

Chlorine monitoring

The Rosemount Analytical Model TCL from Emerson Process Management is a reagent-based system for measuring true total chlorine in water. Ideal applications are the analysis of drinking water and reclaimed wastewater. The reagent, potassium iodide dissolved in white vinegar, is inexpensive and needs replacing only every other month. Sample flow requirement is less than six gallons per day, a real advantage in places where drainage is limited or water is scarce and can't be wasted.

Chlorine monitoring

The Hach CL17 uses DPD colorimetry, the only on-line, continuous measuring technology that is approved by the EPA for reporting chlorine. The device provides unattended operation for up to 30 days and has maintenance that is predictable and requires no special tools. It leverages the company's proprietary DPD formulation that minimizes interferences due to water hardness or minerals and delivers results independent of sample pH, temperature, chlorine concentration, pressure and flow.

Chlorine analyzer

Hanna Instruments has introduced the PCA 320 in-line chlorine analyzer, the only DPD based chlorine system that includes pH and temp. That means a significant cost savings because there is no longer a need for a separate pH controller. The analyzer comes with two 4-20 mA outputs, so both critical parameters can hook directly to SCADA systems.

Bleach test kit

Sodium hypochlorite is not chemically stable and decomposes while in transit and storage. It degrades even faster when exposed to heat and light. Utilities that buy bleach in bulk can use Taylor Technologies' Chlorine Bleach Drop Test (K-1579) at the time of delivery to verify the available chlorine content meets the labeled concentration.

Hypochlorite injection system

Fluid Metering has introduced its new Chloritrol™ valveless metering system for injection of sodium and calcium hypochlorite for purification of municipal drinking water. The system has a valveless duplex pump design. The first pump head is high pressure and injects the sodium hypochlorite directly into the water main. The second pump head functions to remove out-gas bubbles from the inlet side of the high-pressure pump head. The system is smaller and uses less energy than conventional injection pumps.
