Abstract: An apparatus and method for using a dry cleaning machine to clean laundry that reduces environmental impacts by the substitution of ozone for the hazardous solvents traditionally used in the dry cleaning washing process. The apparatus and method for dry cleaning includes the steps of filtering the water whereby any debris present in the water is removed, measuring the dissolved ozone concentration of the water, recirculating the water between the tank and the water purifier until a desired ozone concentration is realized ensuring that the desired dissolved ozone concentration of the water is attained prior to the start of the cleaning process and continuously recirculating the water through the dry cleaning washing machine, the water purifier, and the tank during the cleaning process.

Abstract: A treatment apparatus and method that greatly increases the efficiency and flexibility in using ozone in the laundry process by permitting an operator to set the level of dissolved ozone concentration delivered to the washing machines, depending upon the amount and type of soil on the laundry. Furthermore, the present invention ensures that there is enough dissolved ozone available in the wash water to meet the demand of the washing apparatus. Lastly, the present invention monitors and maintains the desired amount of dissolved ozone to be delivered to the washers.

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.

Abstract: An efficient, economical, portable, movable, 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 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.
