Cross Manufacturing has introduced a new filter specifically designed for the extremely corrosive environment of sea water and estuary water systems. The durable, reliable automatic filtration equipment can be installed in modules to meet even the largest flow. According to Cross, large scale installations such as desalination plants, coastal power stations and cooling tower circuits could all see huge savings in relatively short timescales.
The patented stainless steel ‘zero gravity’ filter coil is already used widely in many areas of industry including water and wastewater treatment and heating and air conditioning plant rooms. A set of filter coils is fitted into a pod and each pod can be backwashed individually and automatically at a selectable differential pressure value.
The filtration process is not interrupted and the requirement for any redundant filtration capacity is eliminated. Cross says that a filter coil made from alloy 625 combined with a large polypropylene housing, polyethylene pipework and bronze backwashing valves is the way forward for large scale sea water and estuary filtration systems.
