Managing biosolids in wastewater treatment applications requires specialized equipment to handle materials that are often viscous, abrasive and odorous. This includes positive displacement pumps, designed to efficiently convey biosolids while resisting wear and tear. Automation and control systems play a key role in optimizing the process, using sensors to monitor material levels and adjust pump speeds for consistent performance. To address challenges like odor, spillage and operator exposure, various containment and disposal solutions are employed, such as continuous bagging systems and auto-leveling dumpsters. Check out some product options below.
Boerger BLUEline
Boerger BLUEline rotary lobe pumps are self-priming, valveless positive displacement pumps used for conveying viscous and abrasive materials. They are resistant to wear and provide pulsation-free operation. Operation is fully reversible with dry-run capability and flow rates up to 7,000 gpm. They are constructed with maintenance-in-place design, allowing for all wetted parts to be easily replaced through the front cover without removing pipe or drive systems. The pump conveys biosolids (primary, waste activated sludge, return activated sludge, digested, thickened, etc.), grease, sewage, scum, lime slurry, alum sludge, permeate and polymers. 612-435-7300; www.boerger.com
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
