The Description of Solid-Liquid Separator Filter Drum Screen
Solid-Liquid Separator Filter Drum Screen, also known as Rotary Drums, separate manure into two components – a thicker portion of concentrated manure solids and a less concentrated liquid portion.
Rotary Drums will remove up to 35% of the total solids, Dairy producers can use Rotary Drums to separate solids from the manure stream, thus improving water quality for use in sand separation, flush flume supply and land applications.
Global dairy and swine production growth has increased significantly over the past decades, resulting in higher manure generation in certain areas and environmental concerns.Therefore, manure management is an essential focus for farmers and environmental regulators.
Animal’s Manure contains many important nutrients that are vital to the growth of crops. When this material is applied to fields in an inappropriate manner or in quantities too large for the soil to handle, this leads to pollution in the form of leaching and runoff, which causes contamination of ground and surface waters. An average cow produces one hundred pounds of manure per day (1 8 tons per year). Composted manure could provide farmers with a more environmentally friendly alternative to traditional manure management practices.
Why Solid-Liquid Separator Filter Drum Screen is needed?
1.With the strengthening of the awareness of environmental protection and energy conservation, most of the farms have built biogas tanks and biochemical tanks to deal with feces and urine.
However, if the fecal materials are not separated by solid-liquid, the effect of biogas culture is not ideal.
Due to the long-term use of biogas digester, a large amount of residue is left after fermentation, which causes the biogas digester to be blocked and the capacity to be reduced, so that the digester can not be used, and the cleaning tank is not only labor-consuming but also extremely unsafe, at the same time, the expense is increased.
2.Direct sale of fresh farm manure is difficult to transport.
3.Manure from farms pollutes the air.
4.The dried manure dewatering by the manure separator can be directly used as the raw materials of fruit trees, forest fertilization, and organic fertilizer to monetize the waste.
The utilization of livestock manure solids separator with filter drum screen can reduce the construction investment of biogas digester, for example:
If a matched solid-liquid separator is used to treat the livestock and poultry excrement in the breeding or slaughterhouse discharging 200 tons of sewage every day, the construction investment of a 400 cubic meters anaerobic tank can be reduced because the concentration of wastewater mixed into the tank is too high.
Anaerobic time also needs to be extended accordingly, so according to 200 tons of sewage per day, if there is no solid-liquid separator for animal manure treatment, then 2000-2500 cubic meters of the anaerobic tank will be built. If the solid-liquid separator is used, the construction of 500-800 cubic meters can be reduced.
How to deal with the dry manure/dung after the separation of manure and sewage?
The water content of livestock and poultry manure treated by the manure separator is low, the moisture content is only about 50%, the appearance is fluffy, no stickiness, the odor is reduced, the hand can’t squeeze out water, and the hand can’t give up.
The treated dry dung can be used as bedding or directly bagged or sold, the moisture content of dry manure after treatment is the best condition for fermentation of dry manure organic fertilizer, which can be directly stirred by fermentation bacteria to produce organic fertilizer.
