Industrial waste water is waste water generated during industrial production. Industrial wastewater is diverse, different in nature and emissions, depending on factors such as industry type, production technology, equipment life, management level …. The sampling of waste water and waste water analysis with specific indicators of waste water source to assess the current state of wastewater indicates that the pollution coefficient will help us find the cause soon and take measures proper handling.

1. COMMON INDUSTRIAL WASTE WATER TYPES
– Pharmaceutical production wastewater / Drug treatment of pharmaceutical products
– Beer production wastewater / Beer factory wastewater treatment system
– Sugar production wastewater / Sugarcane wastewater treatment system
– Rubber production wastewater / Waste water treatment system for rubber latex
– Plating industry wastewater / Plating wastewater treatment system
– Wastewater in Textile and Dyeing / Textile and wastewater treatment systems
