In recent years, environmental issues have been widely focused on.
Most notably, problems related to water environment is an important issue.
Water is used when various products are manufactured on earth. However, when waste water of the above is drained into rivers, seas, or lakes etc., it is at risk for environmental degradation unless it is treated appropriately.
Nomura Micro Science designs and constructs waste water treatment plants that do not negatively affect the environment by making the water clean and environmentally friendly before draining.
At the same time, to meet various customer demands regarding waste water, we continuously strive to propose environmentally friendly technologies accumulated over many years.
Waste water can be classified into organic waste water (waste water contains mainly organic matter) and inorganic waste water (waste water contains mainly inorganic matter). The treating methods of these two waters are different. Organic waste water is treated by decomposing the constituent of BOD (biochemical oxygen demand) using mainly biological treatments.
On the other hand, inorganic waste water is treated by decomposing the constituent of COD (chemical oxygen demand) after separating heavy metals and fluorine (F) by using mainly chemical treatments (treatments using chemicals).
To meet effluent standards, secondary and tertiary treatments are performed.
