Clarifier Mechanism

NeoTech Water Solutions supplying highest quality and most reliable clarifier mechanisms for basic bridge or pier supported mechanisms to those with the most complex and demanding special requirements. Our drive units are high performance and delivers high torque.

Standard Designs exist for basic mechanisms for a wide range of tank sizes. These standard mechanisms are effective, low cost and meet all design codes with minimal engineering costs. Bridge supported mechanisms are supported from a structural bridge that spans the tank diameter and are generally used for the lower end of the range of clarifier diameters.

Full Bridge with Side Feed:

• Bridge & Rake Arms spanning the tank diameter
• Dual Stack drive arrangement with torque overload
• Feed from side connecting to central draft tube
• Available for sizes upto 18M and above

Suction Clarifier What is it:

• A clarifier mechanism employing a unitube header (a specially designed rectangular shaped arm provided with orifices) in place of conventional rake arms, which sucks the settled sludge hydraulically for further withdrawal.
