UV disinfection
Trojan's new technology - TrojanUV Solo Lamp™ - has been incorporated into the new TrojanUVTorrent™ and offers the advantages of both existing medium pressure and low pressure, high output lamp technologies. At 1000W, the lamp is the most powerful in the industry. The power consumption of this new lamp technology is approximately one-third that of medium-pressure lamp systems.

Hypochlorite injectionFluid Metering has introduced the new Chloritrol™ valveless metering system for injection of sodium and calcium hypochlorite. 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.

FlowmetersThe Accusonic Model 7720 Transit-Time flowmeter is designed to address the difficult installation requirements common to large ultraviolet (UV) disinfection systems. The maximum 10 path capability allows the meter to measure with accuracy and repeatability, even in the presence of distorted flow profiles common to large UV system installations. Additionally, the pipe section length required to install a 7720 system is significantly less than other flow measurement technologies for large pipe installations. Measurable pipe/channel sizes range from 8" to 500 feet.

Reagentless chlorine analyzersHach now offers two new reagentless chlorine analyzers, the CLF10 sc and CLT10 sc, for measurement of Free and Total Chlorine, respectively. The chlorine analyzers can be used for process control where real-time, continuous results are beneficial. Because they are reagentless, they are ideal for applications where waste stream management or routine reagent replacement is a challenge. The analyzers include self diagnostics which provide alarms for pH, chlorine and flow deviations, helping users determine whether the process has changed or the instrument needs servicing.
