In a chemical factory large amounts of soiled brine have to be disposed. The brine can be sold as recyclable material after it has been freed from the soiling. The high chemical load of the medium, the high temperatures and especially the large amounts of sludge placed high demands on the design of the treatment system.
During the production of PVC, effluent accrues at different production stages, as for example vacuum filtration. The effluent is precipitated, particles are sedimented and the resulting sludge is drained using a chamber filter press.
