Abstract

In the plant a liquid flow is established with constant speed, between inlet and discharge zones whilst a counter pressure is formed in the upstream part of the liquid flow path, whilst liquid shortage is replenished from a controlled liquid source so that a pre-feed zone is formed between a rotating spindle and the first inlet zone. Liquid and gas are simultaneously fed to the pre-feed zone, the supplied liquid is distributed in the gas which is to be dissolved and this distributed liquid is forced to the inelt zone. The plant treatment tank has lateral, opposed positioned, inlet and outlet liquid pipes and above the tank two suspended motor driven rotors, each with a domed gas supply chamber to which 85% pure oxygen is supplied.
