An apparatus, system, and method relating to a modular water treatment apparatus that utilizes sidestream injection coupled to static mixing are described. The apparatus, system, and method utilizes ozone, with or without hydrogen peroxide, for effective disinfection and/or decontamination of contaminants present in waste water. The disinfected, decontaminated water is suitable for reuse.

Apparatus, systems, and methods for water treatment

Apparatus and methods for water treatment are described, particularly for the simultaneous removal of nitrate, perchlorate, and other organic contaminates from contaminated water using a membrane biofilm reactor (MBfR).

Method for removing contaminants from water using a membrane biofilm reactor

Method for removing contaminants from ground water

Membrane biofilm reactor method for reducing the concentration of oxidized contaminants in ground water

A system and method for the in-situ removal or remediation of contaminants in a soil formation containing a subsurface groundwater aquifer, the method comprising the steps of: injecting a first oxidant into the aquifer at an injection point to create a volume of influence of the first oxidant in the aquifer thereby treating the contaminants contained within the volume of influence; and injecting a compressed gas into the aquifer to increase the size of the volume of influence of the first oxidant. The injection of the compressed gas into the aquifer can also force the groundwater in the aquifer away from the injection point into a surrounding area to transport the first oxidant into the surrounding area thereby extracting contaminants from soil adjacent to the surrounding area.

System and method for remediating contaminated soil and groundwater in situ

Oxidizable contaminants in water are destroyed rapidly and efficiently by exposing the water to oxidizing conditions under pressure. Specifically, a single dose of hydrogen peroxide may be injected into the water, followed by the repeated injection and mixing of low doses of ozone. In each such high intensity mixing/reaction stage, ozone is injected at a pressure, velocity, and direction approximately matching that of the contaminated water flow. High intensity mixing under pressure facilitates rapid and complete oxidation of the contaminants with minimal stripping of volatile contaminants and waste of undissolved ozone. Residual ozone levels after high intensity mixing may be carefully monitored and minimized by adjusting the injection of hydrogen peroxide and ozone in order to suppress the formation of bromate. Additional contaminants may be removed by passing the treated water through activated carbon beds.

Process and apparatus for water decontamination

Oxidizable contaminants in water are destroyed quickly and efficiently by exposing a contaminated water flow to oxidizing conditions under pressure. Specifically, ozone generated from oxygen and hydrogen peroxide are injected into the water flow in at least one, and preferably more than one, high intensity mixing/reaction stage. The ozone and hydrogen peroxide are injected at velocities and directions approximately matching those of the contaminated water flow. High intensity mixing under pressure facilitates rapid and complete oxidation of the contaminants with minimal stripping of volatile contaminants and waste of undissolved ozone. Residual ozone levels after high intensity mixing are carefully monitored and minimized by adjusting the injection of hydrogen peroxide and ozone in order to suppress the formation of bromate.
