System and method of water treatment

Abstract

The present invention generally offers a system and a method that allows a vessel to treat water while providing corrosion inhibition. An oxygen stripping gas source produces oxygen stripping gas that may be pumped directly to, preferably but optionally, a venturi injector, or may first be pumped into an empty tank and then delivered to the injector means. Water being pumped through the injector via a transfer piping means comes into contact with the oxygen stripping gas, and dissolved oxygen in the water transfers to micro-fine stripping gas bubbles generated by the injector. The water and the micro-fine bubbles are pumped from the injector and into the tank, where the micro-fine bubbles float to the surface, and the oxygen is released into the tank's headspace. The deoxygenated water may be re-circulated through the system for additional deoxygenation or released from the tank into the surrounding waterways.

Description

technical field [0001] Water treatment systems and methods using a venturi injector to help remove dissolved oxygen from water, thereby reducing the amount of unwanted aquatic organisms present in the water while inhibiting erosion . The water treatment system and method are useful with ships by allowing them to treat ballast water being transported from one port area to another, thereby inhibiting erosion while limiting harmful environmental impacts Use has a special purpose. The water treatment system and method may have other uses, such as in oil production. [0002] For example, water is placed in ballast tank tanks to maintain stability and adjust buoyancy before the ship leaves port empty or partially loaded. In virtually every case, this ballast water will contain living organisms, the level of which is affected by the level of dissolved oxygen in the water. When a ship reaches its destination and is ready to load cargo, the ship discharges this ballast water, thus ...
