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

Biosolids Heaters/Dryers/Thickeners

HYDRO-THERMAL NON-OBSTRUCTING HEATER

Hydro-Thermal’s Non-Obstructing Heater is suitable for heating and maintaining the digester’s precise temperature (+/- 1 degree F) for improving methane production and sludge stabilization. It also eliminates hot or cold spots in the digester, even during the winter months. It utilizes a small footprint, with direct installation into the existing piping. It is produced using wear and corrosion-resistant metallurgies to withstand grit and highly abrasive materials. Its straight-through design can ensure that rags or wipes do not get caught and plug the heater. With its unrestricted flow there are minimal pressure drops, allowing for a wide range of heating capacity. The heaters have no hot surfaces where burn-on can begin to occur. 800-952-0121; www.hydro-thermal.com

VEOLIA WATER TECHNOLOGIES BIOCON ERS

Rising concern of PFAS contamination of water and soil has sparked interest in this emerging contaminant as it pertains to wastewater sewage sludge. BioCon ERS from Veolia Water Technologies offers a safe and sustainable drying and combustion system for treating PFAS-laden municipal sludge. It combines the efficiencies of a convective air medium-temperature belt dryer with a biomass furnace, which uses the dryer output (dry product) as a biofuel. The heat available in the exhaust is captured and used as process heat in the belt dryer. This integrated dryer and energy-recovery system is sustained by heat generated by the combustion of biosolids to drive the drying process, and in turn the dried material fuels the combustion system, making it a fully energy sufficient and sustainable operation. It combusts sludge between 1,400 and 1,800 degrees F, which is higher than the minimum temperature required for PFAS destruction. 919-677-8310; www.veoliawatertech.com

Centrifuges/Separators

PIERALISI CENTRIFUGAL DECANTER

Pieralisi offers a variety of high-efficiency solutions for sludge thickening and dewatering with significant environmental and economic advantages. The separation of liquid-solids occurs through the centrifugal force generated inside the decanter, resulting from the high rotation speed. The decanter is equipped with a main motor connected to the horizontal axis of the bowl. The product is fed into the machine through a feeding tube. After the separation, the clarified liquid is discharged from one side of the bowl through devices sized according to the specific application, and the dehydrated cake, accumulated on the bowl walls, is transported by a scroll and discharged on the opposite side of the clarified liquid outlet. The decanters are suitable to treat sludge from environmental, chemical, oleo-chemical, mineral- fuel and lube oils, animal-based products, food and beverage processes and can be configured to meet the application requirements. 513-275-4720; www.pieralisi.com

PARK PROCESS SLUDGE KING II

The Sludge King II roll-off dewatering container from Park Process incorporates an engineered design that eliminates trapped water in the bottom of the filter cake. The second center wall filter increases filter area by 33% producing drier cakes in less time. The plastic floor panels that cover the floor space between wall filters and center wall filters serve three purposes. They hold down the bottom of the filter elements, help eliminate standing water and facilitate dumping of filter cake. The inlet manifold is split into three inlets, each with a ball valve, allowing incoming flow to be distributed evenly into the three compartments formed by the two center-wall filters. 855-511-7275; www.parkprocess.com 

Grinders/Shredders

HYDRA-TECH PUMPS S4SHR AND S4SHR-LP

S4SHR and S4SHR-LP 4-inch hydraulic submersible shredder pumps from Hydra-Tech Pumps are designed to continuously rip and shear solids with a 360-degree shredding action. The pump’s carbide-tipped impeller and hardened macerator suction plate work together to produce a violent shredding action that keeps the discharge open. This 4-inch pump is suitable for municipal, industrial, agricultural and institutional waste applications. The S4SHR-LP is narrower in size at 21.5 inches, which allows it to fit through most manholes. Depending on the application, there is a version for portable or fixed installations. A guide rail assembly is available for stationary applications. Combined with HT16 to HT25 power units, the S4SHR is capable of flows up to 810 gpm. The safe and variable-speed hydraulic drive can be used where electric power is hazardous or impractical. 570-645-3779; www.hydra-tech.com

VAUGHAN SELF-PRIMING CHOPPER PUMP

Screening Systems 

EVOQUA WATER TECHNOLOGIES FORTY-X DISC FILTER ARMOR SERIES

The Forty-X Disc Filter Armor Series from Evoqua Water Technologies is a high-rate filtration device that utilizes an integrated pre-screen and stainless steel panels that are designed to accommodate high solids loading capacities and greater hydraulic throughput. The woven optimum primary mesh filter panel utilizes 316L stainless steel threads to create a weave that improves solids collection and rejection, which makes this disc filter suitable for storm flow applications. The panel configuration includes a molded structural frame and pressured assisted seal, allowing the panels to sustain and operate at a higher headloss and provide higher throughput when compared to other disc filter synthetic media. The series combines the technology of outside-in and inside-out filtration into a single PLC controlled unit with influent water flowing through the prescreen (outside-in) into the disc filter panels (inside-out). This combination of two filtration technologies provides an effective option for challenging applications. 844-409-9492; www.evoqua.com

FEDERAL SCREEN PRODUCTS MBBR SCREENS

Federal Screen Products custom fabricates MBBR Screens that maximize flow rates while containing biofilm carriers, helping save on maintenance costs. They are fabricated with wedge wire by resistance welding V-shaped wire on shaped support rods. These thousands of fused points create a honeycomb-like structure that provides a strong and accurate continuous slot. This results in a product that provides accurate flow, distribution and effective media and debris filtration and retention. Wastewater screens are available in a wide range of profile wires to suit most systems, and can be designed in flat, curved or cylindrical form to meet customers’ drawings and specifications. Robust for vertical wall applications, screens are also self-cleaning when designed to the flow rate and are passivated in-house, which allows for a quality of finish, extending product life. 905-677-4171; www.federalscreen.com 

JWC ENVIRONMENTAL XE SCREENINGS WASHER MONSTER

The JWC Environmental XE Screenings Washer Monster is a fully automated grinding, washing and compacting system. It can handle the first flush loading associated with storm flows. It is finely tuned to optimize the cleanliness and dryness of screenings based on the feed rate; reducing the volume of screenings that must be hauled away. It preconditions screenings with a Muffin Monster two-shafted grinder that breaks open rags, plastics and trash to promote washing and removal of soft organics. Liquefied organics return to the plant flow and allow it to achieve cleaner screenings. It has numerous control parameters for programmable wash cycles and a triple-zone spray wash for ultimate cleaning. Its dual-helix auger includes a brush attachment that keeps the screen clean and eliminates material catch points. 800-331-2277; www.jwce.com
