  • Patent number: 10967335
    Abstract: A water container with an ozone diffuser is an apparatus that is used to diffuse ozone gas into water that is either flowing through the apparatus or is retained by the apparatus. The apparatus includes an aeration chamber, an ozone generator coupler, a distribution hub, a plurality of porous tubes, and a degassing unit. The ozone generator coupler allows the apparatus to connect with a pressurized supply of ozone gas. The aeration chamber is used to retain the water that is currently being aerated by the ozone gas. The distribution hub receives the ozone gas from the ozone generator coupler and distributes the ozone gas amongst the porous tubes. The ozone gas is then evenly inserted from the porous tubes into the water retained by the aeration chamber. The degassing unit is used to neutralize the excess ozone before exhausting the excess ozone into the apparatus's surroundings.

  • Publication number: 20110139691
    Abstract: A pressurized wastewater effluent chlorination system including a treatment tank defining a contact chamber and an aeration chamber. The treatment tank receives wastewater effluent. The system includes a pressure vessel within a liquid chlorine storage container positioned in or near the treatment tank. Preferably, the pressure vessel is a floating vessel having a check valve at its bottom, enabling the vessel to fill with a predetermined amount or measured charge of chlorine depending on the position of a float on the vessel. In response to a timer control or float switch, a valve operates to communicate air pressure from a compressor to the vessel to displace the measured charge of liquid chlorine into the wastewater effluent in the contact chamber. Effluent flow and air discharge into the contact chamber enhances mixing of the chlorine and the effluent.

  • Publication number: 20100258485
    Abstract: A solution containing a target compound is passed through a trap column (14) to capture the target compound in the column (14). Thereafter, wash water is introduced in the trap column (14). Then, the setting of a six-port valve (7) is changed and an on/off valve (6) is opened to introduce nitrogen gas through a supply-side passage (8) in the trap column (14). In this stage, the nitrogen gas is warmed by means of a heat-exchange block (10), and the trap column (14) is warmed via a column rack (15). Any water remaining in the trap column (14) is initially thrust upwards by the nitrogen gas, to be extruded from an exit edge (14b) and discharged through a discharge-side passage (20). Furthermore, any water adhering to adsorbent or the inner wall surface of the trap column (14) is quickly vaporized and carried away by the nitrogen gas.
