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;

SEEPEX Smart Air Injection

Smart Air Injection, or SAI, is a SEEPEX customized system solution for pumping over long distances. The system uses compressed air and polymer injections to convey biosolids, or other media with a dry matter content of 20% to 40%, over distances of up to 1,000 meters. This combination ensures a low-pressure level in the delivery line, as well as low friction, which translates into a long life cycle and low operating costs. The system is easy to integrate into existing automation and control systems; reduces the pressure rating of the pipework and valves; and is an enclosed pipework system, eliminating unpleasant odors or rainfall dilution. Open-hopper SAI systems with Smart Conveying Technology reduce maintenance time by up to 85% with the maintain-in-place design, requiring no disassembly of discharge pipework. 937-864-7150;

Biosolids Heaters/Dryers/Thickeners

BDP Industries rotary drum thickener

Force Flow Tote Bin Scale

The Tote Bin Scale from Force Flow allows plant operators to accurately monitor the amount of polymer being fed from IBC-type totes for dewatering. Simply place the tote on the platform and monitoring begins, as there is nothing to install inside the tote. Monitoring systems prevent costly overfeed conditions and enable the documentation of the actual amount fed, which keeps the plant in compliance with federal and state reporting requirements. Users can remotely monitor from SCADA or PLC. The unit is available with the SOLO G2 digital display or with the advanced Wizard 4000 chemical inventory management system. 800-893-6723;

Lutz-JESCO America LJ-PolyBlend Polymer System

The LJ-PolyBlend Polymer System from Lutz-JESCO America is a dependable, motorized mixing machine with a corrosion-resistant housing, large turbine and multizone mixing chamber that provides uniform dispersion energy at the moment of initial polymer wetting. The prime mixing zone fully activates the polymer, while the second mixing zone promotes gentle polymer activation via a small turbine, lessening molecule fracturing. Its stainless steel injection valve prevents agglomerations and reduces the need for extended mixing time. The system includes a clear mixing chamber that provides visual monitoring of mixing polymer feed. Its compact design — only 1 to 1.5 square feet — means it’s light and allows for easy installation and transportation. It has automatic pump speed adjustment via 4-20mA input, water flow sensor and priming port. 800-554-2762;

In The Round Dewatering horizontal drum

The horizontal biosolids dewatering system from In The Round Dewatering has a stainless steel drum with perforated plastic tile lining. The drum is mounted on a roll-off frame for easy transport and unloading. Water trays allow containment of discharge water. An 18,000- to 25,000-gallon batch is mixed with polymer before being filtered in the rotating drum, driven by a 1/2 hp variable-speed electric motor with a heavy-duty chain and sprocket. The turning eliminates crusting and wet pockets to produce uniform, consistent results. The dewatered material dumps easily, and the drum is self-cleaning. 317-563-2072;

Park Process Sludge King II

The Sludge King II roll-off dewatering container from Park Process uses filters that turn 90 degrees at the bottom of the container, leaving standing water in the cake. This also increases the usable area of the filters by 33% over older containers with only one center filter wall. The increased filter surface area and the narrowed sludge compartments formed by the additional filter panel translate into drier cake formed in less time. 855-511-7275;


Vaughan self-priming chopper pump

Self-priming chopper pumps from Vaughan are designed to be easily accessed outside of the wet well while pumping waste solids at heavy consistencies, without plugging or dewatering of the solids. They eliminate the loss in production and mess, along with making it easy to service the pump to get it back in operation. 888-249-2467;

Vogelsang RotaCut

The RotaCut inline macerator from Vogelsang is designed to remove heavy solids from the waste steam while using a spinning blade assembly to reduce debris such as rags, wipes, hair, string, plastics, wood and bone into an acceptable size for the downstream equipment to pass. Instead of shredding hard objects such as metal or stone, the units catch heavy debris in a collection pot for removal from the line. Not only will these units protect pumps and dewatering equipment, they are ideal for biosolids conditioning based on the blades’ ability to create a homogenized slurry. It comes in numerous models designed for a range of flow rates and pressures. They offer an ACC (Auto Cut Control) design, autoreverse, self-sharpening blades and easy inline maintenance. 330-296-3820;

Grit Handling/Removal/Hauling

Envirodyne Systems OctoCell

The OctoCell grit removal system from Envirodyne Systems uses stacked trays to achieve a small footprint. Unique to their design is the inlet trough and tentacle arrangement above the trays, which means the flow path to each tray is the same size/length to better equalize pressure drops, meaning reduced headloss and greater grit removal efficiency. It allows for visual detection of any plugging and serves as a means of controlling flow to each individual tray. It has the ability to engage/disengage trays automatically based on flow variations. A “lollipop” configuration is also available for enhanced control of velocities and reduced organics accumulation. 717-763-0500;

Fluidyne Hydro-Grit

The Fluidyne Hydro-Grit high-efficiency vortex grit-removal system is capable of removing 95% of all grit 75 micron and larger at all flow up to peak design flow. The grit separator can be supplied freestanding in stainless steel or fiberglass tankage, eliminating the need for concrete influent and effluent channels. Alternately, in cold weather climates or areas with limitations with existing hydraulic profiles, the unit can be submerged inside a concrete structure provided by others. It requires a minimal footprint and is designed to limit headloss. No internal moving parts eliminates maintenance inside the tank or structure. Large baffling and weirs abolish the need for a continuous source of flushing water for proper performance and to prevent plugging. It can be used at industrial and municipal wastewater treatment plants to remove fine grit and sand with pre-engineered models ranging from 0.5 up to 50 mgd. 319-266-9967;

Manufactured with high-quality stainless wedge wire, using wastewater screens reduces environmental pollution levels and lowers operational costs over the years. They are fabricated with strong and durable resistance welding, and are available in a wide range of profile wire to suit most systems. They are robust for vertical wall applications and are self-cleaning when designed to the flow rate. Screens are available in a flat, curved or cylindrical form, and are manufactured to meet specifications. 905-677-4171;

JWC Environmental Chain & Rake Monster

The Chain & Rake Monster from JWC Environmental is a continuously raked bar screen for headworks, pump stations and storm overflows. It quickly removes heavy slugs of material to protect downstream processes, making it suitable for when large concentrations of debris are expected. Replaceable teeth are bolted to the rake support, which is bolted to the chain on each side of the bar screen. The rakes pass through a bottom guide track, which avoids the necessity of sprockets and bearings in the sewage flow, increasing unit longevity. Debris is removed by a pivoted wiper with a UHMW blade. Bar spacing is available starting at 1/4-inch. It is designed to fit channel widths from 2 to 10 feet and depths up to 25 feet, with a 5-foot maximum discharge height. 888-418-8316;

Lakeside Raptor FalconRake bar screen
