Fergus Power Pump

Fergus Power Pump logo

Fergus Power Pump, Inc. based out of Fergus Falls, MN has strived for 30 years to be a leader in Biomass Management and Services by providing services and management for municipal, industrial, and agricultural entities for removal, transportation, and land application of Biosolids. In 2007, Fergus Power Pump, Inc. formed a company Fergus Power Products, Inc for sales and leasing of dewatering equipment and dredging throughout the United States. Many municipalities and leading industries are now changing focus and managing their Biosolids by dewatering. Dewatering reduces the weight and volume of solid wastes. The rental and leasing of Dewatering Equipment has become a more common solution for municipalities and industries.

Fenton Dryers

Fenix logo

The Fenton sludge drying system is an automatic batch system. The batch process allows total control of the process to insure the production of a Class A, exceptional quality product. The drying chamber uses a hollow disk propriety-blending rotor to blend the biosolids as they dry to eliminate the need for back mixing and insure optimum drying efficiency. The patented internally heated hollow disk arrangement allows the necessary heat transfer surface area to accomplish controlled dehydration of a wide variety of organic materials. Heated thermal fluid is circulated through the hollow disk as well as the chamber shell to give maximum surface area for drying. Emissions from indirectly heated sludge dehydrators have small amounts of contaminants contained in the exhaust vapors. A high efficiency Venturi scrubber/condenser system condenses the steam to water and scrubs the exhaust stream of air borne particulates. The condensed water is returned to the wastewater treatment system.

AIT Evaporators

AIT Services, Inc. of Brownwood, TX features innovative approach, and long successful history producing some of the most cost efficient and user friendly equipment for the processing of industrial sludge waste, has now been incorporated in the waste water evaporators it produces. The professionals at AIT have researched the market, listened to their customers, and talked to owners/operators of other equipment. These communications, observations and research convinced the AIT staff that others had only partially addressed the problems associated with waste water vaporization. AIT’s patented “V Series” Evaporators have been the longtime front-runner in Evaporation Systems and Sludge Dehydration Equipment. AIT’s products have been put to the test in over one thousand industrial locations under the harshest environmental conditions since 1985.

VORT-X Ring Mixers

VORT-X Ring Mixers logo

The new VORT-X Ring Mixer (VRM) is totally unique and robustly designed to meet the most demanding mixing applications by moving the mixing ring generator plate “up-down / up-down” which produce successive vortex rings that travel through the body of liquid creating an efficient naturally occurring homogeneous mixing process. Compared to traditionally complex more energy intensive rotary mixers that spin blades to stir the liquid, the VORT-X VRM technology provides equivalent mixing with up to 80% less power consumption while also significantly minimizing maintenance and downtime. The VORT-X’s economical and energy efficient design make them incomparably affordable to purchase and operate and are an ideal solution for replacing other more costly mixing methods and equipment.

VORT-X Ring Mixers are ideal for aerobic & anaerobic waste digester sludge and equalization tank mixing to provide homogenous feed slurries and improve the process performance of downstream liquid/solid separation, filtration and dewatering equipment such as:

These mixers are also excellent for de-stratifying liquid storage tanks at tank farms and/or prior to tank clean-outs for more efficient liquid processing and sludge dewatering.
