An SSP is a smaller version of a StinkSTOPper, with a smaller diameter buoy and without a flat stand. It’s propeller orientation is equal to the StinkSTOPper, to allow equal performance while installed in under-the-barn manure-holding-pits, doing the same WISE technology aeration within the pits. The different configuration allows the propeller blades to be lower in the fluid, and allow the equipment to operate when the effluent is at a very shallow depth, allowing pits to be in aerobic condition when they are almost empty.
For reference of “how it works”, please refer to the StinkSTOPper page.
Yet, a significant difference is that pits do not have the same open access to the atmosphere and its wind/sun/oxygen supply that StinkSTOPpers have access to… so how can an SSP work?
First, we must recognize that pit barn designers and builders install good ventilation systems, and there is always air flow from the animal living space above the floor, towards the manure pit below. Odor (air) is not supposed to flow from the pit upward into the barn. To assure this happens in all situations, each pit has a fan pulling air out of it, creating a negative pressure. So…. at all times, air flow out of the pit is required. Downward airflow keeps the pigs from dying from bad gasses. The airflow coming from the basement pit is why pitted barns also stink… even though they don’t have open ponds.
In addition, when agitation occurs, often twice per year, so as to mix up the settled solids with the liquids on top…. additional ventilation is required to assure the nasty gasses don’t go up into the barn. Such gasses, even a few inches above the floor would be deadly, since this is where the hog’s noses are when they eat, play, and sleep. The gasses reaching above the floor are especially dangerous when the hogs are small and first placed and living there. These gasses are potentially deadly, so additional Ventilation is absolutely required during Agitation. This additional ventilation equipment is always present, but not always turned on, unless agitation is in operation.
Simply put… when SSPs are installed into the pits, the additional ventilation fans might also be turned on, and can supply the required atmospheric air to oxygenate the everchanging effluent surface within the pit. With the additional airflow, the same activity provided by the StinkSTOPper on a pond occurs in a pit, by the similar but unique design of the SSP.
SSP’s turn a manure storage pit into an aerobic treatment pit, having no odor, and no noxious gases being created within it. Neighbors have no issue with the larger ventilation fan pulling air across the pit’s surface because the pit has NO odors. Herd health and worker health improves due to the elimination of ammonia gases and other nasty gases that are inherent with poorly ventilated pits.
Due to the startup limitations of PondLift LLC, focus is first for the more easily understood StinkSTOPper installations. SSP’s installations are happening now, installed at select barns for determining design requirements, performance calibration, and performance testing.
As with the StinkSTOPper, photos of the SSP do not show the patented details specific to its exceptional performance. Alternatively, in ponds that are shallow, a StinkSTOPper having a smaller or no buoy can be installed so it rests on the pond bottom, so nothing is seen other than lots of moving water. The video below shows a StinkSTOPper without a buoy. (Yet, you can see the tremendous activity offered in this manure pond.)
