Atlas Copco
Screw Blowers
Atlas Copco’s new line of ZS screw blowers average 30 percent more energy-efficient operation than conventional lobe blower technology. Industries that will benefit are municipal and industrial wastewater treatment plants, where air blowers typically represent up to 70 percent of the total electricity costs. The efficiency of this blower is attributed to the screw technology. Other features that generate increased efficiency and reliability are the integrated gearbox, the oil system and the design that integrates all individual components into a plug-and-run solution.
Elastec
Drum Skimmer
Elastec drum skimmers are designed to handle multiple types of petroleum spills, from jet fuel to crude oil. The skimmers recover oil by rotating a drum through the oil-water interface. Oil sticks to the drum surface and is recovered inside the floating head. The drum skimmers respond to vegetable oil and bio-fuel spills as well, and are effective in recovering pollutants in marine environments and industrial pits.
Abanaki Corp.
EconoMini Oil Skimmer
Abanaki Corp. has added the EconoMini™ oil skimmer to its line of oil removal equipment. The device is ultra-compact at approximately 4" x 3" x 4" and weighs in at 6 pounds. This is the perfect skimmer to use in tight spaces, such as on parts-washer tanks and coolant sumps. It can even be used to skim oil through the 2" opening of a 55-gallon drum. EconoMini requires no assembly and little mounting space. Belts are available in either polyurethane or stainless steel and lengths of 8-, 12-, 18-, and 24-inches.
Assured Automation
Butterfly Valve
Assured Automation's line of resilient seated butterfly valves offer high-flow coefficients, ISO top mounting, a one-piece body with a self-centering disc, and a large selection of direct-mount actuators and gear operators. The valves are available in sizes 2 through 12 inches with a pressure rating up to 225 psi, and the 14- to 24-inch valves have a pressure rating up to 160 psi.
WILO EMU
Packaged Lift Stations
EMUPORT Packaged Lift Stations from WILO EMU are available with an integral solids separation system. The robust system prevents lift station blockages, including systems with a high percentage of solid content. This includes sewage containing material that will not dissolve. The dry-pit design allows pumps to be maintained without contact with the sewage, and it can be installed above or below ground. Sewage flows into a collection chamber where the solid content is held.
Koch Membrane Systems Inc.
Aeration System
Koch Membrane Systems' Puron® submerged membrane modules are designed for membrane bioreactor treatment of municipal and industrial wastewater. The aeration system ensures optimal solids management, a high-flow rate, and reliable operation. The air nozzle discharges air from the center of each fiber bundle at the base. The combination of rising air bubbles, resulting hydraulic cross flow, and the seaweed-like movement of the membrane filters comprise an energy-efficient process that ensures even sludge, hair, and other fibrous components are dislodged and moved out of the system.
