The specification and selection of a Decanting Arm and its operating protocols is essential to its optimum performance.
The Flow Control Group are one of Europe’s leading manufacturers of specialist flow control equipment.

Decanting Arms are used to provide a method of controlling the rate of discharge of waste liquors of all kinds, prior to their entry into Drains and/or Treatment Plants,
Decanting Arms are incorporated into Balancing Tanks or Settling Tanks. To operate the arm is arranged such that the head remains constant over the full depth of drawdown ensuring a substantially constant rate of discharge between top and bottom liquid levels.
