Chlorine analyzers

Chemtrac has introduced the new HydroACT 300 Residual Chlorine Analyzer for the measurement of free chlorine, total chlorine, chlorine dioxide, or pH. It is appropriate for compliance reporting following USEPA Method 334.0. Using a membrane-covered three-electrode amperometric sensor, the probe design incorporates a long-lasting electrolyte solution which significantly reduces pH dependency. Because the analyzer has no moving parts and does not require any reagents or buffers, cost of ownership is low and maintenance is simple. The device is available with up to three chlorine sensor inputs or one chlorine sensor input and one pH sensor input, reducing the overall cost per sample point.

Valve exercising

The Pacific Tek Model PT13 Long Reach Valve maintenance trailers combine everything needed for a valve exercising and maintenance program on a 10 ft. trailer that can be towed by any vehicle in the fleet. The valve operator reaches out from the trailer up to 13 ft. to operate underground valves. It is capable of up to 800 ft. lbs. of torque. The operator communicates directly with a computerized GIS mapping system with GPS to capture and store all of the data about the valve while it is being operated. This information can be downloaded at the end of the day.

Clarification, thickening

The Contrafast® system from Siemens is a high rate clarification and thickening process. Major processes consist of a solids contact reaction chamber, clarifier with tube settler, and gravity thickening in a single process tank. The combination of high shear mixing with thickening allows for higher settling rates and increased sludge densification. The design allows up to an 80% reduction of footprint compared to conventional clarification systems.

Wastewater treatment

The Webitat™ system from Entex Technologies is designed to reduce both the amount of land and the tankage needed for a new wastewater treatment system. The modular units contain fixed film BioWeb™ media and have integral aeration for mixing control and oxygen transfer. The media contain hundreds of thousands of small polyester filament loops in a ropelike hexagonal matrix on a stainless steel frame. The surface of the loops becomes the site where bacteria grow and multiply as they consume the organics in the wastewater for their food supply. By submerging the modules into the biological reactors of wastewater treatment systems, the existing tankage can carry increased biomass and thus treat more wastewater and meet more stringent effluent limits. The integral aeration allows for biomass thickness control, nuisance organism control, and assures high volume transport of wastewater through the module.
