<p>There is described a liquid treatment installation including a tank which defines a substantially vertical flow channel of circular cross section. Disposed coaxially in the flow channel there is a spiral separator plate pack (20) which comprises one or more conical helical plates which define at least one helical flow passage between axially facing surfaces of the plate or plates. The conical helical plate or plates of the separator plate pack (20) consist of a plurality of platelets (10), which have dimensions that allow them to pass through an opening (21) which runs axially through the centre of the spiral separator. The invention also relates to a method of constructing the above liquid treatment installation and to a method for assembling the spiral separator plate pack (20).</p> |
