The Ovivo® spiral blade scraper clarifier is designed for municipal and industrial wastewater treatment applications. It features rapid sludge removal by the action of spiral raking blades. Maximizing sludge concentration, providing low effluent suspended solids and efficient scum removal, this clarifier model is well adapted for primary and secondary clarification process.

The Caisson Thickener was developed to take advantage of the dry well concept of withdrawing underflow into the center column. This concept required a center mechanism where it was possible to service or remove the underflow pumps. The large diameter center column or caisson is sized to house the underflow pumps.

the circular column is in vain. Ground improvement works with conventional auger type mechanical soil mixing is indispensable but contains intrinsic disadvantages as mentioned above. The ground conditions available for the conventional auger type machineries are therefore restricted from the view points of their mixing and cutting abilities.
The conventional thickener employed in the heretofore customary practice of ore dressing and allied arts comprises an upright cylindrical tank of relatively large diameter provided with means for feeding in pulp at the top and center, and with a peripheral launder for catching the decant, i. e., the overflow of liquid from which solids have settled in whole or in part.
Thickener Mechanism The mechanism consists of the bridge, drive and ancillaries, lifting device, feedwell, torque tube and rake arms with blades. Bridge Based on the application, thickener diameter and location, bridge designs are available in a truss type or castellated beam. The MIP designs consider not only the customer's process data,
The Thickener Mechanism suitable for tank upto 35 M diameter consisting of parallel beams/truss type bridge spanning the tank, center column support half bridge type. It can also be designed for Automatic rake lifting Mechanism.

Spiral Scraper Spiral scraper type clarifiers utilize longsweeping, curved scraper blades to move solids across a basin floor. They are similar to scrapertype clarifiers in that they drag settled solids to the collection area, however, they can more quickly remove these solids and thus maintain lower sludge blankets in some applications.

The thickener allows the solids to settle and produces a clarified water stream which can be recycled back to the plant Polymer is used in the thickener to facilitate large floc formation and increase effluent quality Thickener underflow has traditionally been sent to an impoundment or tailings pond.

The slurry is distributed into the to be made to the number of blades, the blade spacing, thickener uniformly across a radius via a manifold angle of attack and type/size of blades (see Fig. 2a). For comprising of four equi-spaced 19 mm nozzles.
Jul 25, 1972 · The bottom of the feed-well is perforated so that the feed-material is discharged directly into the center of the thickener around the column. The sediment deposited in the tank on the floor 14 is moved toward the center by four similar truss-type rake arms 28 carrying scrapers or rakes 30 of conventional form.

Recent improvements, however, in the design of solid bowl conveyor units and disc units may alter this situation. 4.2 The Gravity Thickejner A conventional gravity thickener is shown in Figure 4-4. The thickener normally consists of two truss-type steel scraper arms mounted on a hollow pipe shaft keyed to a motorized hoist mechanism.

This often is referred to as a "two-pour" foundation because the concrete for the footing and the concrete for the wall are poured at separate times. These vertical bars (also called "dowels") must extend a minimum of 14 inches into the stem wall and be hooked at the bottom into the footing as shown in
Conventional Clarifier for Smaller Primary Clarification
Conventional Clarifier The WesTech Conventional Segmented Blade Clarifier is a capable option for smaller primary clarification applications. Each Conventional Segmented Blade Clarifier can be upgraded with several WesTech COP™ Clarifer Design features.
When a section of trench reaches the desired depth, a cage of reinforcing steel is lowered into it. Concrete is then pumped into the trench, displacing the lighter slurry. The slurry is recovered and used again in other sections of the trench. 2 In some cases, bedrock lies close to the surface.

An operator lost control of his 633 scraper when the hydraulic steering line failed. The scraper ended up on the opposite side of the haul road. While waiting to be loaded a 930E dump truck rolled back 35m. At the time the operator was on the ground isolating the truck after it had lost propulsion.

There are three main types of thickeners/clarifiers bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet. Contact Supplier
Cone or trough scrapers are supplied to scrape the discharge cone or trough. Standard rotation is in a clockwise direction. The rakes are powered by a pipe shaft in Type B machines, or by a square cage in Type C mechanisms. Two short arms or two stub arms are
