A new sewer-cleaning system, designed to eliminate downtime during grit and sand removal operations, has been introduced by Garner Environmental Services. The patented new Sewer Hog™ is a multi-purpose sewer cleaning truck that is both closed-loop and non-odor emitting. Rather than shutting down to empty water from the debris tank, the system gives continuous cleaning by separating solids and liquids on the spot, and decanting the separated water back to the containment area. The cleaner can operate in surcharged conditions - no bypass pumping is required. The system can handle both liquid and air, and has the ability to perform positive pumping. It is ideal for operation with wet and/or dry applications in sewer lines, digesters, grit chambers, ponds, lagoons, API separators and lift stations.

Dalec Electronics’ O-6 combines a polarographic dissolved oxygen sensor with an integral RTD for dissolved oxygen and temperature measurement in the laboratory, plant or field. The unit contains a small cathode which consumes minimal oxygen, thus reducing the need for sample stirring and providing a more stable response. A standby switch stabilizes the probe prior to use while economizing the battery power normally required for the display. DO measurement range is 0-19.99 ppm; temperature range is to 199.9 degrees C.

Bilco’s J-AL Door, ideal for most corrosive environments, is a durable solution for wastewater treatment facilities. Available in single- or double-leaf design, the aluminum door is well-suited to provide access to areas located underground or beneath/between floors. The door can be operated by a single person, and functions dependably in harsh environments. Special anti-corrosion hardware includes forged aluminum hinges, a 5086 aluminum cover plate, electrostatically coated compression springs and advanced composite spring housing assemblies. Bilco’s exclusive 70 durometer EPDM debris gasket limits dirt and debris from entering the channel frame. This feature, in conjunction with the standard 1 1/2" drain coupling fully welded under the frame, facilitates drainage.

AnoxKaldnes has announced the creation of a new treatment process for wastewater nitrification in lagoons using the AnoxKaldnes Moving Bed® biofilm reactor (MBBR). The LagoonGuard™ provides a cost-effective way to upgrade a lagoon treatment system. The system features thousands of polyethylene carrier elements that provide a home for bacteria culture. The elements are kept in constant motion throughout the entire volume of the wastewater by a specially designed aeration system and sieves, resulting in uniform treatment. The company recently installed the system for a utility facing ammonia limits and cold weather nitrification issues. The two-stage system removes any BOD in the wastewater and nitrifies all of the ammonia.
