Borger – Rotary Lobe Pumps & Grinders

Borger Rotary Lobe Pumps are positive displacement  pump transferring sludge to and from thickeners, belt presses, centrifuges, rotary presses,  digesters , air entrained fluids, DAF, and industrial slurries. They handle thick solids greater than 2% up to 2000 gpm and pressures up t0 150 PSI. Rotary lobe pumps can run dry and are capable of self-priming. The rotation of the pair of lobes increases suction chamber pressure and creates a vacuum on the priming side of the pump drawing liquid into the pump chamber.

Belt Dryer -Andritz

Andritz - Belt Drying System - provides highly desired Class A Biosolids in a highly marketable sludge pellet / granule. The process granulates the dewatered sludge in a mixer with product that has already been dried. The moist granulate produced here is distributed evenly over the belt in the dryer by a specially designed feed module. The even layer of material on the belt creates optimum conditions for even distribution of the drying air.  This, in turn, is necessary for even heating and drying of the sewage sludge. The layer of material on the belt forms a filter medium for the air flowing onto the granulate layer from above and thus prevents entrainment of dust. The low temperature of the drying gases (< 150°C) and the low dust content in the system facilitate safe operation. The dried material is not exposed to mechanical stress during drying and is pre-cooled before the dryer discharge. The technology - simple, convincing, and successful.

Centrifuge – Andritz

Andritz Centrifuge

Andritz - Centrifuge is manufactured to handle the most difficult to dewater sludges with automated controls and torque control to allow operation with minimum amount of operator attention and maintenance. Field replaceable tungsten carbide feed and discharge ports, field replaceable wear tiles with 20,000 hour wear guarantee and 316L stainless steel bowl  provide a rugged and dependable machine. Andritz commitment to stock spare parts allows the owner to exchange the scroll without having to remove the bowl since both are independently balanced freeing up owners requirements for spare parts. Successful installations include Olathe-KS, Newton-KS, Wichita-KS and Lincoln-NE.

Belt Filter Press – Quantum Low Profile BFP – Andritz

Andritz - Belt Filter Press - SMX & Quantum Low-Profile belt press that significantly simplifies operation, maintenance and lowers cost of ownership. Engineered with the operator in mind, our low-profile design provides modular flexibility, quality design, and low maintenance, without compromising performance, to create the most advanced belt filter press on the market today. The low-profile design eliminates the need for costly platforms. Access for maintenance has been improved with an overall height of only 60” where the gravity zone is at a convenient height. Wide gravity zone and optimized camber wedge to allow perfect distribution of the sludge and ensure gradually increasing pressure, minimizing the possibility of extrusion.

Rotary Drum Thickener – Kusters

Kusters - Rotary Drum Thickener - to reduce sludge hauling costs, increase digester capacity, and to reduce size of other dewatering equipment. Thicken sludge from (0.5% -1.5%)  to outlet concentration of  (5% to 7%) with flowrates of 25 to 400 gpm. Choose Kusters to save significant reduction in polymer consumption compared to competitors in side by side tests. Flocculation tank with maxized detention time

Plate & Frame Press – Andritz

ANDRITZ filter press sidebar SP is the next generation of pneumatic filter presses from ANDRITZ SEPARATION and is fully modularized. As there are only a small number of hydraulic power pack sizes available, spare parts management is easier and service technicians require less training. THE ANDRITZ filter press SP series offers the right size for each throughput requirement.. Solids are separated reliably from liquids in the ANDRITZ quality you are accustomed to without using electricity. No compromise on process reliability, safety, or easy operation.

Features include a re-designed power pack that ensures stronger, faster, and quieter operation, a special pin design for better distribution of forces, and a manual pneumatic plate shifting system that provides additional operating convenience.

Dry Polymer Preparation System -Polyblend & DynaJet- UGSI

UGSI PolyBlend® DP Series Dry Polymer Feed System offers a unique two-stage method of initial high-shear mixing followed by low-shear mixing. The mechanical activation of the dry polymer ensures polymer optimization and lowers operating costs. An innovative stainless steel "hollow wing" mixing impeller in the mix/hold tank reduces polymer consumption by providing proper energy at low speed through impeller size and recirculation to prevent agglomerations while minimizing polymer fracture. With minimal maintenance and a small footprint, the PolyBlend® DP is fully automatic and easy-to-operate.

PolyBlend & Dynablend Liquid Polymer Wetting & Activation System – UGSI

UGSI Chemical Feed Polymer Feed Systems offers the most comprehensive line of both hydraulic and mechanical polymer activation methods with the Polyblend® mechanical polymer feeders and with the Dynablend and Dynajet hydraulic polymer feeders. Both technologies have been used in the field for the past several decades. The Polyblend® technology was introduced in 1972 and the Dynablend and Dynajet technologies were introduced to the market in 1985. The combination means UGSI Chemical Feed now boasts over 10,000 installations and three decades of field experience.

Dewatering Containers; Roll-off, Self-dumping (Sludge, Grit, Oil/Water), Polymer, Sand Separator – Park Process

Park Process - manufacturers dewatering containers, with a porous bottom to dewater sludge, grit or other fluid. The dewatered portion is collected to a drain. The false bottom can be permanent with stainless steel wedge bottom of various openings or with a disposable needle punched polypropylene geotextile filter. The most common type of dewatering container is based on a roll-off box design, although any type of container that is water tight can be made into a dewatering box. This includes containers that are commonly referred to as self-dumping hoppers and front loaders. Park Process manufacturers industrial filtration, Oil-Water Separators, batch and inline polymer make-up systems, eductors,  mud cleaners, and oil field mud hoppers.
