Biosolids Heaters/Dryers/Thickeners

Hurst Boiler Euro Series

The Euro Series from Hurst Boiler has a full wet-back radiant heat transfer area that promotes internal water circulation and rapid heat absorption. Separate rear tube sheets allow each pass of tubes to expand and contract at their own rate without tube-to-sheet stress. Tubes are mechanically rolled, flared and beaded, making any tube service a simple matter. The only refractory in this design is a rear plug, which allows easy access to the furnace for inspection. It is available in eight models from 100 to 2,000 bhp. It is designed for optimum fuel efficiency and has proven in certified tests to meet, and often exceed, the efficiencies of four-pass boilers. There are no refractory baffles to replace or maintain. 229-346-3545;

Hydro-Thermal Non-Obstructing Heater

Hydro-Thermal’s Non-Obstructing Heater is suitable for heating and maintaining the digester’s sludge temperature for breakdown. It utilizes a small footprint, with direct installation into the existing system piping. Precise temperature control will increase biological activity, maintain a tight temperature band, and eliminate hot or cold spots in the digester, even during winter months. It is produced using wear and corrosion-resistant metallurgies to withstand grit and highly abrasive materials. The straight-through design helps minimize downtime caused by wipes or rags collecting and plugging the heater. If material gathers and plugs other heating devices (like a heat exchanger), then these units must be opened up and manually cleaned to remove the solids plugging the system. They have no hot surfaces where burn-on can begin to occur, like in a tube/shell or tube/tube heat exchanger. 800-952-0121;

Composting Equipment

Roto-Mix 1220-20 

The Roto-Mix 1220-20 horizontal rotary compost mixer has a mixing capacity of 1,220 cubic feet and can hold a maximum load of up to 36,000 pounds. It is designed to thoroughly mix materials to ensure rapid decomposition to produce quality compost. This rotary compost mixer, equipped with a GeneRation II Staggered Rotor Mixer, will uniformly blend materials in a tumbling action that does not pack material and helps introduce air into the mix. The rotor lifts the material past the wedging point of the lower side auger, resulting in an aerated mixture while lowering power requirements. Total movement of material in the mixing chamber eliminates dead spots that are common in conventional auger mixers. Optional conveyors allow for the discharge and distribution of mixed nutrients with microorganisms into static compost piles or windrows. It is available in truck or stationary units. This size of mixer works well with large volume composting operations. 620-225-1142;

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, which is 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;

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 primary 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;

Park Process Sludge King II

JWC Environmental Monster Metal 

Wastewater is tough on grinders. Gritty material wears the cutters and acidic conditions corrode them. Previously, operators needed to choose hard steel alloy cutters and sacrifice corrosion resistance; or choose softer corrosion-resistant stainless steel cutters and sacrifice abrasion resistance. Monster Metal from JWC Environmental is a hard, corrosion-resistant alloy. It is made with a balance of carbon for strength and chromium for corrosion resistance to increase the usable life of grinder cutters. 800-331-2277;

Vaughan self-priming Chopper Pump

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 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 also 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 auto-cut control design, auto-reverse, self-sharpening blades and easy inline maintenance. 330-296-3820;

Grit Handling/Removal/Hauling

Smith & Loveless PISTA Stainless Steel Grit Chamber

The PISTA Stainless Steel Grit Chamber from Smith & Loveless is designed to offer reliable and long-lasting grit removal performance that is easy to install and can be inserted into existing tankage without the need for new concrete work, including for retrofitting aerated grit chambers. It is constructed of high-quality 316 stainless steel that is corrosion-resistant and designed to provide 50 years of paint, rust and maintenance-free service. The prefabricated system is significantly easier and more cost-effective to install for most sites than typical concrete chambers. Contracting costs are reduced or eliminated altogether, while system downtime and bypass pumping or dewatering needs are reduced. Because it is built exactly to specification, each system is guaranteed to perform exactly as designed and contractor issues are eliminated.

Screening Systems

Duperon FlexRake IQ 

The Duperon FlexRake IQ platform provides real-time smart screening for maximum resilience at the headworks. It tackles high peaking factors due to extreme weather and difficult debris like flushable wipes, first flushes and settled solids. This is accomplished by system improvements and a sequence of operations that automatically responds in real time to optimize the screen field. The reimagined design focuses on smart enhancements to the raking device to manage heavy solids loading events with four times increased debris removal capacity, improved grit and rock handling and greater solids capture. During peak flow conditions, it adjusts the bar screen opening itself to provide additional hydraulic capacity and safety factor, matching the best capture rate to the flow volume in real time. 800-383-8479;
