ETPs are commonly used in: 🥛 Dairy & milk processing 🧵 Textile industries 💊 Pharmaceutical industries 🍴 Food processing 🧪 Chemical industries 🏭 Engineering/manufacturing units 🧴 Distilleries and other process industries Example: A 100 KLD ETP is designed to treat approximately 100,000 litres of industrial effluent per day.
