A Filter Press can Deliver a 50% Improvement in Dry Solids Concentration

It is common knowledge that Hydroflux prefers to use the HUBER screw press for dewatering primary sludge generated from wastewater treatment plants across many industrial sectors, but although screw presses will provide a good result when dewatering certain metal sludges, the use of a filter press often wins hands down in these applications.

At a recent installation at a tannery, a filter press was used to dewater a chrome sludge generated by a Hydroflux HyDAF system – achieving a dry solids concentration in excess of 55%. When one compares this to any alternative dewatering methods – that may achieve only 35% dry solids – this represents a 50% improvement.

Such an improvement in turn provides a significant saving in disposal costs, particularly as metal sludge often needs to be disposed of at a secure landfill site at a high unit rate.

How does a filter press work?

It works by pumping the flocculated slurry into the centre of the press where it fills the void between filter plates that are fitted with a fine cloth. The pressure from the pump forces the liquid through the filter cloths, whilst solids are retained and squeezed by the pressure of the feed pump. The filtrate flows between ridges in the plates to the corners where it discharges.

The filter press is a simple process which, although it requires some operator intervention, is very easy to operate and maintain. Aside from replacing the cloths every few years, a filter press requires no other spare parts.

A filter press can also be used for dewatering primary or biological sludge from a wide range of applications including metal processing, ground water treatment, site remediation, general and heavy industries, pulp and paper, vegetable industries and in breweries and wineries.
