Chlorination of potable water, wastewater effluent, and cooling water is widely used throughout the world to control biological activity in the water. Disinfection of potable water with chlorine ensures that tap water is safe to drink once it has passed through the distribution system. Wastewater disinfection helps to ensure that receiving streams are safe for recreational use, and cooling water chlorination reduces biofouling that can degrade heat transfer efficiency. In addition to these common uses, there are many other applications where chlorine addition helps to reduce biological contamination....

Gas Phase Sensing: Measurement is made without contact between sample and electrodes, eliminating the potential for sensor fouling. Standard Method: Total chlorine is measured using EPA recommended method of reaction of sample with buffer and potassium iodide, and measurement of iodine released in the reaction. Alphanumeric LCD: Provides residual chlorine display, alarm status indication, and all configuration information. Two Control Relays: Relays are programmable for setpoint, deadband, and time delay. Relays offer pulse frequency and pulse width modulation control modes in addition to simple...
