Mass finishing process water lifting station.

This machine formed part of the critical sub-contract metal laundry facility at Walther Trowal UK’s Surface Technology Centre. Riley Surface World staff have seen this machine working in a well maintained and serviced environment, prior to professional de-commissioning and operated by trained and knowledgeable operatives. In addition the manufacturer, Walther Trowal, is available to support this after sale, see below.

The lifting station can be utalised in one of two ways, either as a transfer station for transporting locally the effluent from the finishing machine to a remote water treatments system, or as a recirculation tank to hold a buffer of treatments and compound  process water which can be returned under spray to the process bowl.

Water recycling:

The recycling of the process water from the finishing process does not only reduce the consumption of water (up to 98%), but it also reduces the usage of compound (up to 90%). In addition, it reduces the cost of waste disposal.

Lifting tank:

The lifting station is a low height robust storage tank made from polyethylene with an angled bottom. The tank is designed to offer gravity feed with pumped return.

Equipment included:

Diaphragm pump, compressed air diaphragm pump which is a self priming high lift mechanical pump for the transfer of the contained solution/sludge.

Coarse pre-filter, mesh basket inlet for the removal of large solids that may become present in the returning effluent stream.

Level pump control, through twin floatswitches which will stop and start the diaphragm pump and the process requires

Motorised paddle, a .37kW geared paddle motor to maintain any solids, fines or chemistry in suspension within the solution whilst within the tank.
