Biological treatment of wastewater: Special use of bacteria
Turning coke plant wastewater into drinking water
Cleanliness requirements for industrial wastewater are increasing. In many countries, authorities are steadily raising standards for wastewater quality. China is taking this a step further: It wants to banish all wastewater from its industries. For example, coke plants in China are only licensed if the operator guarantees that all wastewater will be recycled. To date, however, even the most thorough cleaning processes have been unable to purify coke plant wastewater to the required extent.
