In order to select the right type and size of the filter, it is often recommended to perform filtration tests for new applications. The main goal of these filtration tests is to determine the optimal filter media and filtration process conditions. Two filtration tests results Sulphurnet recently visited a plant in Chili where such a...Continue Reading

Process optimization with self-cleaning candle filters. A producer of herbicides was investigating a plant optimization in which filtration played an important role. The process included a continuous reactor and the products were filters on a belt filter to recover the product, which was a solid end product. The mother liquor was recirculated back into the...Continue Reading

Main filtration cake from ideal pre-coat Now that we understand the 3 main possible outcomes of the pre-coat layer, we must understand these are the worst and best possible scenarios, these possibilities are in a line from low flowrate to high flowrate. This means that you can find any deviation in along this line, knowing...Continue Reading

How the filtration flow rate affects the filter internals and what happens to the particles in the different scenarios? Believe it or not, the flow rate, especially in the pressure leaf filter, is a very critical point. Flow rate control must be continuously improved along the rest of the filtration system. The filter cake, the pump...Continue Reading
