    Station for complex water treatment SKO-10K. One of the first steps in most conventional water purification processes is the addition of chemicals to assist in the removal of particles suspended in water. Particles can be inorganic such as clay and silt or organic such as algae, bacteria, viruses, protozoa and natural organic matter.

    The water is distilled multiple times to ensure that it does not leave deposits on the machinery or cause corrosion. RO is used to clean effluent and brackish groundwater. The effluent in larger volumes (more than 500 m 3 /day) is treated in a water treatment plant first, and then the effluent runs through RO. This hybrid process reduces ...

    Biota are an essential component of most sewage treatment processes and many water purification systems. Most of the organisms involved are derived from the waste, wastewater or water stream itself or from the atmosphere or soil water. However some processes, especially those involved in removing very low concentrations of contaminants, may use ...
