Different Forms of Waste Containment

By Lianne Derocco


An efficient way of maintaining animal waste management system is essential, since a large amount of manure, or animal wastes is being produced in a livestock business. The proper storage and treatment of these animal wastes must be implemented, in order to eliminate, or at least prevent and reduce the negative effects it may bring to the surrounding environment and to human beings in that affected environment.

A lagoon system, or a manure lagoon, is one example of a waste management system. It is a man-made earthen pit where the wastes, coming from animal pens are being piped into. Once transported in to the lagoon, in a period of 20 to 50 days, a two layer is formed: the sludge or the solid layer, and the liquid layer. The sludge layer is a more solid layer formed by the settling of sediments from the manure to the bottom, while the liquid level is composed of grease, scum and other particulates. Oxygen is sealed out by the top layer which allows an anaerobic condition for the bacteria to treat the waste. The liquid layer can be used to fertilize soil and the sludge layer must be drained periodically for maintenance.

Though a lagoon system is a widely used waste management system, adverse effects are still evident, especially when no proper maintenance is observed. The process of decomposition by anaerobic bacteria produces toxic gases such as ammonia and hydrogen sulfide, which are seriously harmful to human and animal health. Ammonia can be lethal at an elevated concentration, causing irritation to the eyes and lungs. Hydrogen sulfide, on the other hand can cause more complications, from irritation of the respiratory tract to sudden loss of consciousness, or at worst cases, coma or even death. E.coli, a bacteria causing mild to severe diseases on the digestive tract, is also of alarming count in a lagoon system.

Another system for livestock waste management is the Deep Pit system. The system is simply a cylindrical hole in deep soil, several feet in depth and diameter. The inner wall could either be masonry or a wall of stone. Either is acceptable as long as it is strong enough to shore up the soil. It must be carefully observed that cesspools must not be used in porous soil or where groundwater may come within five feet from the bottom. They should also be downhill and at least 500 feet away from wells or springs used for drinking water. With deep pit system, liquid from raw wastewater leak through the soil while solids decayed and collected as composted matter in the base of the pit.

A septic tank is mandated to eliminate the use of cesspools or deep pit systems. Cesspools have higher risks of contaminating nearby source of drinking water even though it has been built on a reasonable distance. Insects can enter into the pit and can be a vector for bacteria to spread severe diseases that could extremely threaten human health.

Proper maintenance must be carefully observed to prevent or at least reduce the harmful effects of both the lagoon and deep pit systems. For a more efficient and natural management of wastes, equipment made of natural and biodegradable plastic, Agra Sphere, has been created. This works together with Activator Plus, a natural microbial formula, to reduce sludge on lagoon and pits. Begin by treating the lagoon or pit with Activator Plus, a microbial formulation that improve the breakdown of suspended organic solids on sludge. Activator Plus prevents the toxic gases to be excessively emitted. After the treatment with Activator Plus, Agra Sphere is then tossed on the lagoon to allow sludge to be liquefied; this causes the right nitrogen to be absorbed by bacteria cells. These bacteria decompose on the soil and feed the soil well by slowly releasing the right kind of nitrogen. It is the fast released nitrogen that causes burning to the crops on the soil. Agra Sphere aids in reaching the aim of efficiently maintaining different waste management system.
