How the FloutŪ Works
The FLOUT® Flout is a contraction of the name Floating Outlet®. Rissy Plastics has pioneered the technology
since 1992 and the original test installation in Andover, CT is still working perfectly. Thousands of Flout installations are at work in North America, Europe, South Africa, New Zealand,
and Pacific Islands.
HOW IT WORKS
A chamber of sufficient dimensions to contain the required dose has an upper inlet and a lower outlet, usually
at floor level. No plumbing extends below the floor. The outlet diameter is usually 3 inches but may be 4 inches, 2 inches,
or as small as 1 inch. A box shaped vessel floats on the surface of the liquid in the chamber. There is an opening in the
upper side of the vessel and a ballast weight is attached. A length of pipe extends far into the vessel, through the side,
and attaches to a special flexible connector the same diameter as the pipe. The other end of the connector is connected to
the outlet, usually via a tee fitting with a vent extending above the maximum liquid level.
1. The Flout® is free floating, hinging on the flexible connector as the chamber
fills. 2 When the Flout reaches maximum, liquid spills in, sinking it and opening the outlet to flow. 3. As the liquid
drains down to the top of the Flout, it empties and begins to float again, closing the outlet, and begins a new cycle.
The flexible connector acts as a hinge, allowing the vessel to float
ever higher as the chamber fills. When the vessel can float no higher, liquid spills into the vessel, forcing it to sink to
the floor, allowing the liquid to flow through the outlet. When the liquid level drops to the top of the vessel, flow stops
when the vessel drains and re-floats in the remaining liquid. A single outlet flout may serve more than one disposal area with the use of distribution boxes. A multiple outlet flout provides individual outlets for each section of the disposal area. Outlets may be combined for larger flows or incrementally
combined. For example, take a 5 outlet multiple Flout and combine two outlets then three outlets for a perfect 2/5, 3/5 split!
This system makes gravity dosing easy to implement with it's simple design, ease of installation, and trouble
free operation. Unlike a siphon, the Flout does not need a downward projecting trap. The trap makes for difficult installation
in the field or in the precast plant. And a Flout never needs and can never loose a prime. The best way to understand
how it works is to watch this video of the first Flout installed in 1992.
