    Abstract: 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.

    Abstract translation: 通过将受污染的水流暴露在压力下的氧化条件下,水中的可氧化污染物被迅速有效地破坏。 具体地说,从氧气和过氧化氢产生的臭氧在至少一个,优选多于一个的高强度混合/反应阶段中被注入到水流中。 臭氧和过氧化氢以与受污染水流相近的速度和方向喷射。 压力下的高强度混合有助于快速和完全地氧化污染物,同时最小程度地剥离挥发性污染物并浪费未溶解的臭氧。 通过调节过氧化氢和臭氧的注入,以便抑制溴酸盐的形成,仔细监测和最小化高强度混合后的残留臭氧水平。

    Abstract: 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.
