It is important to understand the design features and fluid properties before employing a particular skimmer type. Some factors to consider are: Oil removal flow rate: Alternative Skimmer designs have different oil removal flow rates. Volume removal rates for Oleophilic skimmer types (drum, brush, disc, belt) are comparatively low.
The valve is often described as a needle valve, although this is a misnomer. A true needle valve uses a tapered needle in a tapered seat, so as to provide fine control over flow rate. The float valve uses a pointed needle against a square-edged seat, to give a positive shut-off. As the float relies on gravity, the chamber must be mounted ...
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
A later innovation, the floatless fill valve, designed for low-profile, low-flow toilet tanks, uses a pressure-sensing diaphragm mechanism instead of a float to control the inlet valve. [4] Delay valves, which delay the filling until the level has dropped to a low level, avert short-cycling of the water supply.

An automatic control valve consists of three main parts in which each part exist in several types and designs: Valve actuator – which moves the valve's modulating element, such as ball or butterfly. Valve positioner – which ensures the valve has reached the desired degree of opening. This overcomes the problems of friction and wear.
