Solid Liquid Separation

Small particles such as powders sediment very slowly even if they are metals of large specific weight, while such particles float up slowly if they are lighter than water in specific weight: so, they stay suspended in water unless they are left in a stationary condition for a long period of time. But when these matters are generated in large amounts within a factory, it is difficult to leave them in a stationary condition for a long time due to the limit of time and space. Thus, in the past, filters, large amounts of floccing agents, or pressurized floatation collection systems were needed, incurring high initial costs and running costs.
