Turning Cloudy to Clear!

The filtering of turbidity from fluids is an important processing step in a number of industrial production sequences. Usually a combination of candle and disc filters are used together with filter additives such as silica gel and diatomaceous earth which - together with the turbidity - form a dry sludge on the actual filter. The basis of this horizontal filtration technology are disc-shaped, single-sided filtering elements within a pressure vessel. The circular metallic filter cloth is mounted onto a base plate and fixed at the edge, e.g. with a clamping ring. As the filter cloth is fitted loosely, it naturally tends to corrugate - to a greater or lesser degree - so that cracks or craters develop in the dry sludge. This reduces the effectiveness of the filtration as it allows turbidity to pass through.
A solution to this problem are PACO filter plates that have particularly dimensionally stable filter cloths and a very high-quality finish. The cloths are fixed by a pre-tensioning system and tightened to a tension that is specifically calculated for the individual plate design. As a further service, PACO can prepare all common makes of horizontal filter and, when required, also provide the complete finishing.
