Water, waste water
Cake produced by filtration requires disposal. Total solid content (TS) therefore needs to be high in order to keep disposal costs low. Membrane filter presses deliver the most efficient method of mechanical dewatering and drying and is therefore the predominant technology used in water and waste water treatment. Klinkau's extensive range of membrane plates offer the ideal solutions for the most diverse of needs. Existing chamber filter presses can be retrofitted with Klinkau membrane filter plates. The variable design of the plates makes them also suitable for use on any standard make of membrane filter press in new facilities.
Applications: water, waste water
Ground water treatment and soil remediation
Ground water treatment and soil remediation have greatly gained in importance over recent years due to ongoing environmental laws and new methods of soil analysis.
New requirements in environmental management necessitate the treatment of ground water in landfills. Recent years have shown that soil often becomes contaminated due to environmental disasters. For example, Klinkau's empty chamber replaceable membrane filter plates were used for soil decontamination following an oil-tanker catastrophe in France.
Drinking water treatment
Special filter elements are crucial in the treatment of drinking water. Fast cycles and high flow rates are involved and filter plates with large filtration surface areas are used.
Filtration can become complex depending on the source of the untreated water. Conditioning takes place using polymers, alum or aluminium sulphates. However, official regulations may prevent treatment using conditioners. This then results in extremely thin filter cakes with a risk of differential pressures emerging from uneven cake formation within the individual chambers.
Klinkau empty chamber filter plates are ideally equipped to cope with such difficult circumstances. Klinkau's overhanging membrane plates ranging in sizes from 1200mm to 2000mm x 2000mm have proven their operational ability here.
Filter presses are often equipped with mechanical systems for automated cake release. Filtrate drainage is therefore usually positioned externally and underneath.
