Abstract
An apparatus and method for the purification of contaminated water whereby the contamination level of the wastewater is automatically monitored and treatment self-adjusted and continued until the desired level of purification is reached. Specifically, if upon treatment a pre-set purification level is not obtained a water recycle control means completely precludes the uptake of additional contaminated water and recycles wastewater within the apparatus until the desired level of purification is obtained. The present invention more particularly pertains to an efficient, turn key, economical, movable, automatic and compact apparatus and method for treating a fluid with ozone comprising multiple pressurized contact columns which are arranged in a hybrid parallel and series column configuration, which utilizes a unique water recycle control system and piping arrangement to improve the efficiency of the mass transfer of ozone into the water and increase its solubility by increasing the contact time between the water phase and the gas phase. The apparatus and method of the present invention has the further advantage that it requires minimal installation and may be used to fulfill the clean…
