ADVANTAGES OF PLATE SETTLERS 1. The settling distance is reduced by 98%, 3.5” compared to 15’ in a conventional basin 2. Plate settlers provide a “perfect environment” low velocities and minimized hydraulic effects 3. Effects from wind, turbidity spikes and temperatures are minimized 4. Plate settlers “overlap” therefore basin footprints are 20% as large as a conventional basin 5. Effluent turbidities are
Plate settlers are set on 55 0 angle Falling particles see the “Projected Area” of each plate settler The loading rate is the rate of flow over the projected areas i.e. .3 gpm/ft 2 The Projected Areas overlap The settling surface is much larger without plate settlers
