Affordable Dif-Jet Air System from Fortrans Eliminates Odor from Animal Waste Lagoons

Contributed by: PumpScout Staff

Fortrans Inc., a manufacturer of self-contained pH control and monitoring systems, offers the Dif-jet air system as an affordable way to eliminate odor from animal waste lagoons. Odor problems on swine production farms affect the quality of life in the surrounding areas, which has caused some states to impose moratoriums limiting the growth of farmers. The aerator will allow the farmers to continue business without causing unnecessary health hazards and pollution problems.

Aerating the lagoon is a great way to increase and maintain the amount of dissolved oxygen in the waste lagoon, but pump aerators that spray waste water into the air are not very efficient. An average waste lagoon, or series of lagoons, may require 5 to 10 spray aerators, which can require up to 300 HP to operate. Not only are these units expensive to run, they are also expensive to maintain, and this method has no way to circulate the aerated water for enhanced bacterial digestion.

Anaerobic lagoons have been suggested as a solution, but they are very expensive and they also require regular maintenance. In addition, up to 4,000 cubic feet of explosive gas must be stored on the farm, causing a number of safety issues.

Some plants use bottom mounted diffusers, which provide adequate oxygen for bacterial respiration and good digestion of organic waste. Unfortunately, the cost to install and maintain bottom mounted diffusers is too expensive for farmers. The diffusers would also foul quickly and become inefficient due to the amount of solid waste being treated.

The patented Dif-jet air injector from Fortrans Inc. offers cost-effective aeration in animal waste lagoons. The aerator doesn’t foul during operation in high-solids water, and the system is located outside the water itself, so maintenance is easy.

The aerator system can add up to 3 pounds of dissolved oxygen per hour and only requires a low pressure blower of 8 to 10 psi. The total HP required would range from 45 to 80, and a new system only costs between $100,000 to $250,000.
