Abstract:
A method for contacting a liquid and a gas and illuminating and circulating the resultant fluid mixture, comprising the steps of:injection of small bubbles of gas at low pressure into a liquid filled chamber,the chamber being inclined at an angle and having an abrupt change in dimension at the upper end thereby creating a gas trap inducing agglomeration of small bubbles andthe upper and lower ends of the chamber being connected separately by smooth curvilinear tubing to a reservoir of liquid thereby achieving a circuit and allowing large bubbles to emit from the gas trap into the reservoir via the upper riser tubing, the said large bubbles assisting the small bubbles in circulating the contents of the system andthe chamber and any part of the system being illuminated wholly partly or not at all on a full or part time basis, and all in combination assisting removal of at least one target component.
