PondLift StinkSTOPper – Pond Agitation

Company Description:

An Aerobic pond encourages aerobic bacterial growth, and decomposes manure aerobically, quickly and without odor. StinkSTOPpers make the pond/pit be a hostile environment for anaerobic bacteria, and without that type of bacteria, are odor free.

Implementing WISE technology quells the stench of manure and waste storage ponds. PondLift, describes the action of our devices: StinkSTOPpers create a strong upward current which lifts the water and lifts solids from the bottom, spreading them across the top of the pond. This is the basis of WISE technology. The outward spreading across the surface enhances oxygen exchange into the effluent, providing exceptional rates of oxygenation to support aerobic reactivity.

Solids brought to the surface often continue to float, becoming mini-biological reactors at the surface, quickly decomposing while providing a platform for additional aerobic bacteria activity and growth/expansion.

Technology Description:

StinkSTOPpers can be controlled by Variable Frequency Drives (VFDs) which allow them operate at different speeds. They can also operate at full speed for those who don’t want VFD’s at their site.

In normal operation, StinkSTOPpers operate at 1/2 speed… using around 500 watts of energy. A higher speed will create a faster current, moving much more water upward and outward at the surface. StinkSTOPpers are designed to be able to “dive” down to the bottom of the pond at higher speed, if such operation is desired by the owner. (This is valuable during initial installation, when there is a backlog of manure to be decomposed.)

Higher speeds use almost all of the 1.5hp’s wattage requirements, but are amazing to watch: The diving speed turns the propeller fast enough to provide enough upward thrust of water to pull the entire device, buoy and all, to the bottom of the pond to dislodge even the most encrusted solid matter from the bottom.

Yet, the continuous and relentless upward water flow at 1/2 speed is adequate for servicing a pond that is “caught up” with its treatment.

Each StinkSTOPper can effectively decompose the wastes of 100 animals weighing around 1,000 lbs each (or 1,000 animals weighing 100 lbs each).

Power is supplied to the StinkSTOPper by power cord, rated for underwater use. The power cord is tethered to one of the positioning cables, and tied to shore. Two positioning cables are needed for each StinkSTOPper, with them forming a straight line across the pond, with the StinkSTOPper held in position between the 2 shore anchors.

Power is supplied to the site, with 220v single phase being the minimum requirement, allowing for 3 phase power to be used as well. If 220v single phase is supplied, Variable Frequency Drives are a necessary part of the installation, which convert the power to 3 phase, which in turn allows the StinkSTOPper to be operated in reverse for a short time in case something does wrap on the propeller. This option is anticipated to be needed only rarely, but is put in place to eliminate the need to pull a unit to shore to clean off the propeller. If 3 phase power is supplied to the site, VFD’s are not required, but solid state controls can be installed instead.

PondLift implements patented design for StinkSTOPpers, and performs radically different and high performance aeration and circulation. PondLift revolutionizes performance and renews the ability to aerate agricultural waste ponds, not only within the heartland of America, but around our nation, Canada and the world.

Technology Strengths, Weaknesses and Critical Indicators

Aeration:

  • Primarily applicable for flush system followed by primary solids separation and within a region that has concerns regarding local odor emissions from long-term storage lagoons.
  • Capital costs for the mechanical surface aerators and their platforms/electrical connections are moderate.
  • Operating costs, even with limited aeration can be high due to high utility costs for continuous operation of energy intensive aerators.
  • Well-researched, understood and engineered system with multiple vendor platforms available across industries, including manure treatment.
  • Several types of aerators are available in the market that are suited for dairy operations.
  • Specification requirements of aeration equipment and its installation depend on farm size, manure characteristics, and odor mitigation goals of that dairy farm.
