Thickener Optimization Package Advanced Thickening Technology

WesTech’s Thickener Optimization Package - TOP™ A Better Process Solution WesTech Engineering has taken the next step in advancing thickener technology with our Thickener Optimization Package (TOP). The TOP thickener design approach adds innovative features to the thickener to provide a b ­ etter process solution. • Even feed distribution • Optimal feed slurry dilution • Minimized flocculent consumption • Enhanced thickening • Improved dewatering and underflow control Short-Circuiting and High Floc Consumption EvenFlo™ Feedwell An uneven current in the settling zone of the thickener can...

Ineffective Dilution AirLift™ Dilution Thickeners often require dilution of the feed to improve settling rates and floc consumption. Dilution systems designed to educt clear water from a single location can cause uneven flow patterns in the quiescent settling zone of the thickener. WesTech’s AirLift dilution system uses an airlift pump to draw clarified water evenly from the thickener surface into the feedwell. Dilution systems driven by density differential can be less effective when the density outside the feedwell increases. Neither system allows for operator adjustments of dilution flow...

TOP™ Ten Design Features 1 EvenFlo™ Feedwell The feedwell is a core component for every thickener. Energy dissipation and even feed distribution from the EvenFlo feedwell help to minimize short-circuiting in the sedimentation zone. AirLift™ Feedwell Dilution This option allows thickener operators to target a specific dilution flow rate with controlled precision without upsetting quiescent settling conditions. Optimized feedwell dilution can minimize chemical consumption while maximizing the solids settling rate. Patent Pending Patent Pending Flow distribution patterns can be analyzed using...

Inclined Dewatering Pickets As settling solids begin to...

WesTech Thickeners Each WesTech thickener type can include any combination of the TOP™ Ten thickener features. HiFlo™ High Rate Thickener WesTech has a worldwide installation base with application experience across the spectrum for minerals and industrial high rate thickening applications. WesTech’s HiFlo Thickener equipped with the TOP Ten features is an industr y-leading, applicationspecific solution that will provide: • Lower flocculent consumption • Consistent underflow density • Stable operation AltaFlo™ Ultra High Rate Thickener The AltaFlo is a rakeless thickener that uses rapid...

HiDensity™ Paste Thickener WesTech’s HiDensity thickener produces non-settling thickened tailings with lower viscosities and underflow concentrations than what is produced in the Deep Bed paste thickener. The HiDensity thickener offers the advantages of paste and thickened tailings for large tonnages. Reduced viscosity associated with the underflow concentration of the HiDensity thickener results in lower pumping costs – an important factor for deposition areas far from the plant. Deep Bed™ Paste Thickener The WesTech Deep Bed Paste thickener produces nonsettling and non-segregating...
