On any wastewater treatment plant with static recirculation flow control.
The F&A 2353 valve can be applied to any wastewater treatment plant with static recirculation flow control.
The manual adjustment of a “telescopic head” requires many adjustments, especially when the flow rate of the clarifier is variable.
Other parameters require adjustment of the head such as a change in the viscosity of the sludge or a variation in the concentration in the aerated tank.
In addition to preventing clarifier clogging and eliminating recirculation monitoring, it provides a more stable sludge concentration to the thickener system and saves flocculant.
