Potable water treatment e.g. employing limestone to reduce acidity, recycles water to fluidize bed in first vessel, maximizing transfer coefficients whilst minimizing size and cost of plant

摘要

A side stream (Q2) is branched off from the part-treated water and recycled to the stream to be treated (Q1) yielding total flow (Qges). An Independent claim is included for the corresponding plant, comprising appropriate vessels, treatment beds, valving, pipework and pumps.
