Introduction to Wastewater Clarifier Design
The use of high-rate ballasted solids separation technology allows increasing design clarifier SOR to at least 160 m. 3 /m. 2.day (4,000 gal/ft. 2.day). Because the ballast enhances solids removal, its use in primary clarification reduces the solids

Beginners guide to thickeners
In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.

Industrial Sedimentation and Filtration Equipment
The AltaFlo™ is a rakeless thickener that uses rapid dewatering in the hindered settling zone to achieve a very high settling rate. The AltaFlo typically operates at twice the settling rate of a high-rate thickener. The geometry of the unit provides for a deep compaction bed, allowing the thickener to achieve relatively high underflow densities.

DEWATERING * CONVENTIONAL AND HIGH-RATE THICKENERS
High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

Ultra-high-rate thickeners are typically rake-less with few moving parts or wear items. "It has a higher flocculent consumption than high-rate or paste thickeners," Keirn said. "It offers a decreased underflow density do to the lack of rake and the high polymer dosing." Paste thickeners are so named due to their higher underflow density.

DEWATERING * CONVENTIONAL AND HIGH-RATE THICKENERS
The objective of a thickener is to separate low-density slurries into a relatively clear liquid and a high-density slurry, or sludge. All thickeners depend on gravity to allow for settling fine solids. A thickener consists of a circular tank with a gradually sloping cone-shaped bottom with a discharge in the center.

Thickening
Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below. High rate thickener feed wells are designed to disperse flocculants thoroughly into the feed end to admit the flocculated slurry into the settling zone of the thickener without destruction of the newly formed floccules.

Biosolids Technology Fact Sheet
thickener designs usually include circular tanks, 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter. The dimensions are based on prediction of settling due to gravity alone. To assist solids transport, gravity thickener bottoms are constructed with a floor slope between 1:6 and 1:3. Rectangular units have been used as gravity thickeners.

Difference Between Clarifier and Thickener
The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.
