HiFlo™ High Rate Thickeners / Clarifiers
PHOENIX HiFlo™ High Rate Thickeners clarify wash plant effluent water while thickening the slurry to 40-45% solids, greatly reducing the underflow slurry rate to the slurry pond. PHOENIX Thickeners use sedimentation technology to maximize the water recovery rate, providing clarified overflow water that can be recycled and reused in the process. HiFlo™ High Rate Thickeners / Clarifiers provide rapid liquid-solid separation of high flow rates with optimum flocculation and adapts to process fluctuations.
HiFlo™ Thickeners are available in several standard sizes & custom configurations including bolt-together tank, flat bottom, elevated tank, rake lift, and embeeded stave.
For complete elimination of the slurry pond, a PHOENIX Belt Filter Press or Filter Press may be added downstream of the HiFlo™ Thickener to dewater the thickened slurry.

Features & Benefits
- Thickener design clarifies water while thickening slurry from wash plants
- High underflow solids for reduced or eliminated slurry pond storage area
- Overflow launder channels clarified water back for reuse in the process
- Slurry deareation tank provides laminar flow of multiple product streams
- Self-diluting feedwell enhances liquid-solid separation and provides a consistent feed density
- Robust rakes aid in compaction while moving solids to the discharge cone
- Fully electric, low horsepower drive eliminates risk of hydraulic oil contamination, and ensures efficiency and reliable operation
- Bolt-together tank design provides easier/quicker plant erection
- Underflow flush lines help minimize line plugging
Slurry Feed
Dirty feed enters de-aeration tank.
Polymer
Polymer added to the feed through submerged pipe.
Center Well
Treated feed enters center well.
Flocculation
Flocculated solids settle to the bottom very rapidly, while rakes aid in compaction.
Clarified Water
Clarified water overflows into a collection weir.
Solids Discharge
Concentrated solids are raked to the center and flow to a pump.
