A PROCESS AND APPARATUS FOR TREATMENT OF WASTE WATER, EFFLUENT AND BIOMASS

摘要

A waste water treatment system (10) applies an agent or agents (17) directly to the contents of a biological waste water treatment tank or vessel (11) which includes biomass (12) and waste water (13) therein. Application of the agent or agents (17) can be by any means appropriate for the agent concerned including recirculation and/or mixing with a carrier such air or oxygen or oxygen enriched air. The process and apparatus is applicable to a wide range of biological waste water treatment processes from the municipal to the industrial and including the textile and/or paper industries. The agent or agents (17) may also convert difficult to degrade organic matter into more easily biodegradable organic matter and/or oxidises colour and odour producing agents.
