Hydrocyclone separators, sometimes called enhanced gravity separators, use centrifugal force to remove oil droplets from oily water. As shown in Figure 7-16, static hydrocyclone separator…

Federal regulations and most authorities having jurisdiction require that “free oil” be removed from deck drainage prior to disposal. It is extremely difficult to predict…
In every system substances that show up as “oil” in the laboratory test procedure will be dissolved in the water. This is especially true where…
The first step in choosing a water treating system is to characterize the influent water streams. It is necessary to know both the oil concentration…
A drain system that is connected directly to pressure vessels is called a “pressure” or “closed” drain system. A drain system that collects liquids that…
The skim pile is a type of disposal pile. As shown in Figure 7-18, flow through the multiple series of baffle plates creates zones of…
Disposal piles are large diameter (24- to 48-inch) open-ended pipes attached to the platform and extending below the surface of the water. Their main uses…
It can be shown mathematically that an efficient design must have a high gas induction rate, a small diameter induced gas bubble, and relatively large…
In dispersed gas units gas bubbles are dispersed in the total stream either by the use of an inductor device or by a vortex set…
Dissolved gas designs take a portion of the treated water effluent and saturate the water with natural gas in a contactor. The higher the pressure…
