Residual chlorine monitoring

Pennwell web 300 273

ATI’s Q46H Chlorine Monitor is an upgraded version of the Q45H system for continuous monitoring of free or combined chlorine. The monitor capabilities have been expanded to include options for a third analog output or for adding additional low power relay outputs. Digital communication options for Profibus, Modbus, or Ethernet have been added as well. The system uses a polarographic membraned sensor to measure chlorine directly, without the need for chemical reagents.

The Jupiter gas detection system, Model HVS4000, monitors and reports accurate information about hazardous and toxic gases to a SCADA monitoring systems. Its features include a sensor life indication, two settable internal relays, a three-digit display, dual MODBUS connections and 4-20 mA proportional gas level output. The system can be connected directly to the company’s Emergency Gas Shutoff systems to immediately remedy a gas leak. This microprocessor-based system detects most toxic gases in parts per million (ppm), including: ammonia, carbon monoxide, chlorine, chlorine dioxide, ozone, and sulfur dioxide as well as oxygen deficiency.

Wastewater disinfection

PPG Industries has introduced Accu-Tab® wastewater tablets that provide enhanced erosion control and reduced wicking to effectively kill bacteria, control algae and destroy organic contaminants in small-scale aerobic water treatment systems. The calcium hypochlorite wastewater tablets are manufactured with HI-SIL™ H-303 silica to provide a steady source of available chlorine. The PPG-engineered silica is an erosion modifier that replaces aluminum stearate, which can be violently reactive under certain environmental conditions.

Arch Chemicals 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 of the earlier system, such as optimum solution consistency and a small footprint, but its loading and feed rate capacities are much higher, allowing for service in larger treatment facilities. The new model features an HMI with touch screen for easier functionality. The feeder uses NSF Standard 60 listed dry calcium hypochlorite briquettes and patented spray technology to produce fresh liquid chlorine solution as needed.
