WebbTheory of Water Filtration. Thomas R. Camp , F.ASCE. PDF. Tools. Share. Abstract. The Kozeny equation of laminar flow through granular materials is extended to the transition region by means of a chart of the friction factor versus the Reynolds number. A chart of the backwashing number versus the Reynolds number is developed for estimating wash ...

WebbUses for bed filters Drinking (potable) water, pretreatment for high purity water, e.g. electronics industry, effluent treatment, beer and wine clarification, sea water filtration before injecting into oil reservoirs. Fig. 4.1 In a filter increasing resistance causes liquid flow to decrease with time – at constant pressure drop WebbThe principle that most home water filters rely on to do their job is called adsorption. Not to be confused with absorption, this process refers to the way that molecules dissolved in a solution can adhere to a solid surface, creating a film on that surface while the rest of the liquid passes by.
