Industries such as power, textile, steel, metal treatment, refineries, petrochemicals, etc. generate waste-waters which are low in organic contamination and can be subjected to membrane‐based treatment for providing very good quality of recovered water. Same is the case with domestic sewage which can be recycled conveniently.
RK Water supplies Recycling System, which incorporate extensive pre‐treatment to remove turbidity, organics and foulants so as to protect the membranes from fouling and get maximum service life. Using advanced membrane‐based pre‐treatment systems for removal of hardness, alkalinity and silica, RK Water can offer highest recoveries through multiple stages of reverse osmosis.
For many types of reuse applications, wastewater must pass through numerous treatment process steps before it can be used. Steps might include screening, primary settling, biological treatment, secondary clarification, tertiary treatment, and disinfection. A combination of these technologies can meet strict treatment standards and make sure that the processed water is free from bacteria and viruses. Some of the typical treatment technologies include ozonation, aerobic treatment, reverse osmosis, and advanced oxidation. Wastewater is generally treated to only secondary level treatment when used for irrigation.
