Ultra Deep thickener is a rake-less thickener that provides mixing, flocculation and internal dilution followed by clarification and positive sludge collection and removal in a single tank. The principles of flocculation have been further adapted to a new design that will thicken slurries at an even higher rate than a typical high-rate thickener.

High Rate Thickeners. Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to …

Dec 14, 2015· High rate thickeners; HOW THICKENERS WORK. Feed enters the velocity break box where excess energy is removed from the slurry prior to entering the Thickener feed pipe. Flocculant is added into the feed pipe and mixes with the solids, forming larger agglomerations, that will rapidly settle to the bottom of the Thickener.

High Rate Thickeners Paste & High Compaction ... Paste Thickening is an environmentally friendly method used to compact and store tailings at ultra-high densities. To gain the maximum efficiency DELKOR has developed a system to reduce the yield stress generated by these paste

AltaFlo ultra high-rate thickeners perform well as tailings thickeners, in CCD circuits, as concentrate thickeners, and in leaching circuits. The low CAPEX economics of an AltaFlo also make it a perfect solution for dewatering non-profit streams. The heart of …

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.

Belt Filter Press. The PHOENIX Belt Filter Press dewaters slurries of pre-thickened solids from a pumpable liquid phase to a solid, conveyable, and stackable cake. Over 30 years ago, PHOENIX belt presses were applied for dewatering thickened tailings resulting from mineral washing processes. Today, belt filter press dewatering remains a ...

PHOENIX has long been a market leader in separation, classification, thickening, and dewatering equipment for the aggregate industry. One recent innovation is the AltaFlo Ultra High Rate Thickener, featuring: No moving parts. Minimal space requirements. High underflow solids (as high as 50-60% in mining applications).

A high density thickener produces thickened tailings. The difference between a high rate and a high density thickener is the underflow will not segregate—that water remains bound into the mixture. A deep cone, or deep bed, thickener produces paste. Both high density and deep cone thickeners depend on retention time rather than area.

The innovative dewatering cones system provides rapid removal of water from the settling and compaction zone of the thickener. The AltaFlo operates with typically the same flocculant consumption as compared to a high-rate thickener processing the same material. EvenFlo™ Feedwell. Optional Feedwell to Maximize Performance.

This high performance clarifier incorporates the design of internal solid recirculation thereby motion and makinq Handles high inlet suspended solids load upto 3000 ppm while giving consistent treated water quality of less than 20 ppm. Wide flow rate and size range— flow rates as high it more economical than conventional clarifiers.

Jan 01, 2016· The ultra-high-rate thickener is sized mainly on hydraulic loading and would therefore have a smaller diameter (and hence, smaller footprint) than the equivalent high-rate thickener. The size limit of this type of thickener (12-m diameter) may therefore require multiple thickeners to …

The washing intensity and cycles are individually adjustable. The washed screenings are further conveyed in the rising pipe to the press zone where they are pressed and dewatered by the compacting screw to aDS content of 35 – 45 %. The wash water from screenings compaction which is rich in carbon is discharged back into the waste water stream.

This zone is compaction zone. Sludge blanket is defined as the top of the feed zone. The height of this blanket is the main operational control that the treatment plant operator has over the thickener. By increasing the underflow rate, the operator can lower the blanket, and hence the solids residence time

– High-capacity plate settlers ranging from 5 MGD to 150 MGD Biosolids Management ThickTech™ Rotary Drum Thickener The ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate- all achieved with very low polymer use.

The underflow flow rate is also monitored to keep the mass-balance of the thickener. Rake torque Sensor : The Rake arm of the thickener is suspended from above the feedwell of the thickener. Temporary plant shut-downs or power failure will allow free solids to settle and undergo compaction when the thickener is started again.
