JDV Equipment Level LODOR
The Level LODOR from JDV Equipment provides water quality professionals a means to dispose of processed waste, control odors and limit waste exposure to operators. It uses auto-leveling technology to level the waste material. This increases the fill percentage of a dumpster without operator intervention, slide gates or extensive control strategies, while limiting exposure to potentially hazardous material and working conditions. Made for indoor or outdoor use, it can save valuable indoor square footage or eliminate the need for additional building space by installing the system outdoors. The covers are custom made to cover standard 20-, 30- and 40-yard dumpsters, with an overall footprint barely larger than a standard dumpster. The shaftless option uses replaceable ultra-high molecular weight liners that will reduce screw wear. The shafted option can be used for increased efficiency and has easily accessible grease points. 973-366-6556; www.jdvequipment.com
Paxxo Longopac Fill
The Longopac Fill continuous bag system from Paxxo can connect to the discharge point of machines used to move, dewater or compact screenings, grit and biosolids. Material is then deposited in a 90-meter-long continuous bag for odor containment and spillage control. The cassette bag can be sealed with ease, and the material and odors are trapped inside, cutting down development of bacteria and fungus spores. 770-502-0055; www.paxxo.se/us
SEEPEX Laser Feed Control
The SEEPEX Laser Feed Control system revolutionizes the automated management of media levels in open hopper progressive cavity pumps. It shines when handling challenging media with high solids content such as dewatered wastewater sludge. Harnessing the power of noncontact laser proximity sensors, the level control system precisely detects the presence or absence of media entering the hopper, as well as its volume. This data is seamlessly processed by the SEEPEX TOUCH controller, which intelligently adjusts the pump’s operating conditions for optimal performance. Configured with carefully selected parameters, the system is responsive. When the lasers identify any fluctuations outside these preset conditions, it smoothly adjusts the pump speed or activates the start/stop mechanism, ensuring consistent and reliable operation. 937-864-7150; www.seepex.com
Biosolids Heater/Dryer/Thickener
ELODE USA Electro Osmosis Dehydrator
The Electro Osmosis Dehydrator from ELODE USA reduces disposal costs by drying sludge cake to half its weight or less. Its compact design integrates seamlessly with existing dewatering equipment. Rather than using heat, chemicals or mechanical forces, it uses only electricity, driving a rapid 1-minute electroosmosis process to separate water from solids. As a nonthermal dryer, it uses far less energy than thermal ones, bypassing the inefficiency of evaporating water to steam. It also requires less peripheral equipment, making it a practical alternative to conventional thermal dryers by minimizing costs, space requirements and maintenance downtime. 201-568-7778; www.elodeusa.com
