Introducing environmental technologies that reverse water pollution.

Due to the outbreak of Avian Influenza(AI) in Korea, the Korean government is concerned about water contamination around AI carcass burial sites, makes an all-out effort to control water quality

Concerns are rising about water contamination caused by leachate from carcass burials in the midst of the worst AI outbreak in Korea. Leachate emerges when the buried carcasses are decomposed and the contaminated water gets permeated and drained into the soil and emerges to the surface of the earth. The Ministry of Environment of Korea is making an all-out effort to prevent the permeation of leachates from the buried carcass and to manage the quality of ground water near the burial sites and the water in spring water sources.

Water contamination is harmful to the human body and the ecosystem

At the end of 1950s in the Czech Republic, the “blue baby” syndrome occurred wherein the body color of the children who drank nitrate-contaminated water turned blue. And 8% of the babies with the syndrome died. Moreover, in 1986, a fire that broke out in a chemical warehouse in Switzerland led to water contamination of the Rhine River, causing a massive aquatic kill.

Development of a technology to apply the process of advanced treatment and reuse of waste water from steel manufacturing process

Environmental R&D technology to purify waste water (1)

Technical Overview

  • Technology for reuse and advanced treatment of industrial waste water (waste water from steel manufacturing process) that applies rapid pretreatment technology (Hydro J.B. process applied), customized MF/UF membrane separation technology for industrial waste water, continuous flow membrane separation technology (tankless system) and cost-effective brine treatment technology (BBF).

Strengths compared to the existing technologies

  • This technology can be used for various industrial uses: for example, it can be used not only for reusing waste water, but also for reusing sewage, rainwater and turbid water; for pretreating rainwater; for advanced technology for treated water from waste water treatment facilities; and for technology to purify eutectic solution.

Environmental R&D technology to purify waste water (3)

Technical Overview

  • By applying biological filtration and ozone advanced oxidation process, this technology can remove the nutrients (nitrogen and phosphorus) and traces of nondegradable contaminants in the effluent from wastewater and sewage treatment facilities

Strengths compared to the existing technologies

  • Remove 90% of soluble contaminants and can treat nitrogen and total phosphorus under 3mg/L and 0.05mg/L, respectively
  • Minimizing the land use by using compact facilities and the ability to manage low-temperature and the loading of solid materials
