Grit removal Mechanism

Grit removal is the process used to remove sand, silt and grit from water.

Grit (and sand) removal is often found in the headworks of wastewater treatment plants (WWTP). Grit removal can also be used to remove sand from river water intakes prior to processing for potable water, use in industrial applications to remove fine abrasives, as well as being used to remove grit entrained in sludge.

Clarifiers and Clariflocculators

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening.

Clariflocculator is a combination of flocculation and clarification in a single tank. It has two concentric tanks where inner tank serves as a flocculation basin and the outer tank serves as a clarifier.

We manufacture Central Driven Clarifiers upto 45M dia(Shaft/Cage Driven.)

We manufacture Peripheral Driven Clarifiers upto 60M dia.

We manufacture Central Driven Clariflocculators upto upto 35M dia(Shaft/Cage Driven).

We manufacture Peripheral Driven Clariflocculators upto 65M dia.

Rectangular Clarifiers

The selection of type of primary clarifier depends on:

• Regulation and preference of regulatory authorities
• Size of installation
• Local site condition

The advantages and disadvantages of rectangular clarifiers over circular clarifiers are summarized below:

• Advantages:
• Occupy less space when multiple units used
• Provide longer travel distance for settling to occur
• Less short circuiting
• Disadvantage:
• Possible dead corners
• Sensitive to flow surges
• Restricted in width by collecting equipment

Higher maintenance costs of sprocket, chains & flights

Both rectangular and circular configurations have been commonly used in clarifier basins. The relative merits of the two have been discussed at length for decades. Historically, the selection of rectangular versus circular clarifiers has been based on past experience and the preference of the design engineer or design company. Initial wastewater treatment plant designs in the United States were reasonably balanced between rectangular and circular when collector or scraper systems were designed from steel. With the introduction of biological treatment, corrosion became more of a concern and circular clarifiers became more popular

Sludge Thickener

Sludge Thickening is a process in which the solids concentration is increased and the total sludge volume is correspondingly decreased, but the sludge still behaves like a liquid instead of a solid. Thickening commonly produces sludge solids concentrations in the 3% to 5% range, whereas the point at which sludge begins to have the properties of a solid is between 15% and 20% solids. Thickening also implies that the process is gravitational, using the difference between particle and fluid densities to achieve the compaction of solids.

Claritube Settlers

Tube settlers are gravity settlers wherein the settler is provided with tubes to increase the surface area of separation of solids from the liquid. The tubes are placed in an inclined fashion.

A tube settler is made up tubular channels that are placed adjacent to each other. These are placed at 60 degrees and combined to increase the effective settling area of particles. The settling area of the particles is made in such a way that it is less deep than that of the conventional clarifier.

Tube settlers are common in rectangular clarifiers, where they increase the settling surface area of particles. This works by means of increasing the vertical distance the particle will have to move before settling. By the use of parallel tubes, tube settlers make upward water movement to be uniform.

Sand Traps , Telescopic Valve

A sand trap provides for the quick removal of settleable (sand) particles from the water, in order to prevent damage to mechanical components in the water treatment plant. A sand trap is usually carried out as a concrete gutter, where the waste water flows through while sand particles settle.

Telescopic Valve is used to get sludge sampling
