Treatment & Clarification Equipment

We manufacture both varieties: Peripheral and Centrally Driven Clarifiers. Our Yashwant Clarifiers are made from Single Internal Spur Gear with Cyclo Gearbox Drive to reduce power and maintenance requirements. Yashwant Clarifiers are easy to install and provide years of hassle-free and un-interrupted service to our clients. Our design is robust and indigenous, with easily replaceable spares and top-notch after sales and maintenance services.

Our clarifiers have been installed in Industrial and Municipal Sewage Treatment Plants throughout India and up to Tank Diameters as large as 40 Meters. Our Centrally Driven Clarifier has at its heart a 1200mm Diameter Spur Gear which provides prolonged service without breakdown and interruptions.

The clarifier tanks can be classified in two groups:
Mechanized and Un-mechanized.

In an un-mechanized clarifier, the bottom of the tank is shaped like a funnel, with a steep slope. The sludge slowly settles towards bottom, and slides down the slope to collect at the lowest point of the funnel-shaped bottom.

In a mechanical clarifier, the bottom of the tank has only a gentle slope toward the center. The sludge settles uniformly across the floor of the tank. A set of slowly rotating rubber blades sweep the sludge into a hopper at the center of the tank.

Early torque ratings were based on the Lewis Beam formula, a criteria that considered tooth strength only. In the 1970's, specifications began to appear requiring that spur gear ratings be based upon AGMA standards, at that time AGMA 210 and 220 for spur gearing, and AGMA 440 for worm gearing. AGMA 210 brought durability into the rating equation. Since that time, AGMA 210 and 220 were combined into new standard AGMA 218, and later into ANSI/AGMA 2001. AGMA 440 evolved into ANSI/AGMA 6034.

Throughout the evolution of Clarifiers throughout India, our gear drives have consistently evolved incorporating the best design practices and indigenous designs and concepts. Only suppliers such as us who have kept current with, and reacted to, the changing standards can truly state that their gear drives are "Designed in full conformance with required standards."

Bridges & Structural Their Designing

• Erection of Bridges have immense important in the working of a clarifier.
• We understand the vitality of designing and manufacturing bridge to mount our clarifier assembly. The bridge though as light as possible must also be as strong as possible.
• Hence we pay special attention to designing and manufacturing.
• We have special consultants with expertise from Clarifier Manufacturing and Erection Field to design and analyze the Structural Design Aspects of the Bridges.
• Our Bridges are manufactured with highest safety standards and safety factors for withstanding high load & stress application at site.
• The bridges are designed so as to facilitate easy on site assembly and also provide for highest strength and structural stability.
• We have expertise in manufacturing full and half bridge structures which are easy to assemble, highly cost effective yet comprehensive in strength.

Sewage sludge is highly reactive. Long-term storage may lead to septic conditions resulting in bad odors which bother not only residents.

The aeration of sludge limits the formation of odors caused by anaerobic bacteria. The sludge is kept fresh. Additional treatment of the off-gas is not required. The aerator provides for effective aeration and thorough mixing of the sludge and simultaneously controls the foam layer. Thus capital costs are reduced.

In case redundancy is needed several smaller units can be used. Basically the aerator consists of drive, foam cone and impeller. The rotating impeller sucks sludge from below and air or foam from above through the foam cone and swirls the mixture of both radially to the sides.

The unique design of the Aerator makes it very sturdy and low-maintenance. There are no bearings or seals in the immerged part and all submerged parts are made of stainless steel or plastics.

Aerator with Foam Control can either be mounted with a mounting bracket or on float assemblies.
