Membrane filter press are commonly used in coal washery operations for dewatering coal tailings and producing a dry cake that can be easily transported and disposed of. Coal tailings are the by-products of coal washing processes, which typically involve the separation of coal particles from the water and other minerals.
Membrane filter press consist of a series of chambers that are separated by filter membranes. When the slurry of coal tailings is pumped into the chambers, the water is forced through the filter cloth under high pressure, leaving behind a cake, after that the cake be compressed by membrane plate, to squeeze out more water from it. The membrane technology used in the filter press allows for higher filtration efficiency, which results in a drier cake with a lower moisture content.
In addition to dewatering coal tailings, Membrane filter press can also be used for other applications in coal washery operations, such as separating coal fines from water and producing a clean water stream that can be reused in the coal washing process. Membrane filter press can also be used for treating other types of industrial wastewater and sludge.
Overall, Membrane filter press are a reliable and cost-effective solution for dewatering coal tailings in coal washery operations, helping to reduce waste and improve the efficiency of coal washing processes.
The moisture content of coal tailing cake that is produced from a membrane filter press can vary depending on several factors such as the properties of the coal tailings, the operating parameters of the filter press, and the characteristics of the membrane used in the filter press.
However, in general, Membrane filter press are known to produce drier cake with lower moisture content compared to other types of filter presses. The moisture content of the coal tailing cake produced by a membrane filter press can range from 15% to 25% or even lower, depending on the above-mentioned factors.
It is worth noting that achieving a lower moisture content may require additional processing steps, such as pre-conditioning the feed slurry or using multiple stages of filtration. Therefore, the exact moisture content of the coal tailing cake produced by a membrane filter press would depend on the specific operating conditions and the desired end-product specifications.
