What makes LBM different?
LBM has unique experience in thickener operation, optimisation and fault finding, gained in operating and studying the behaviour of thickeners from different suppliers.
LBM has undertaken the hands-on operation of thickeners from the control room. We have investigated thickener behaviour including flow patterns, settling and density profiles through the mud bed.
These observations and investigations enabled LBM to formulate and test several hypotheses, which culminated in alternative feedwell and rake designs based on new understanding and knowledge.
LBM’s experience in thickener operation and behaviour resulted in our unique thickener control philosophy, which has been implemented and tested. The great benefit is control instrumentation that is proven to require minimal maintenance in the thickener environment.
LBM undertakes flocculant testing and specification with the best available technology. Testing equipment includes a flocculant pipe reactor that enables us not only to recommend the flocculant type but also the number and position of flocculant dosing points. LBM also tests the effect of variations in thickener feed rate. Such testing makes it possible to minimise flocculant consumption and optimise thickener performance.
LBM has the equipment and expertise to test and specify thickeners for a specific application.
Our expertise in thickening, including “paste thickening”, has been proven in many project consultations, thickener specifications and peer-reviewed publications.
LBM’s changes in feedwell design, rake designs, thickener control philosophy and flocculant testing methodology were reported at the Paste 2012 conference.
