Organic/Inorganic Wastewater

A wide variety of items supporting people's lives are produced at factories. Water is used in the production process and used water is discharged from the plant. Wastewater from factories has a significant impact on the water environment, including rivers, lakes, and seawater, so it is necessary to appropriately treat and manage the wastewater. In addition, there are organic and inorganic wastewater, each of which has different treatment methods. HORIBA contributes to wastewater treatment through its lineup of meters and sensors that can handle a wide range of wastewater.
