KIREETY DINAKAR Hi-tech Institute of Advanced pharmaceutical Sciences NATCO HOUSE, Road No:2, Banjara Hills, Hyderabad—500 033. 01Slide 2: 02Waste water?: Used water……….. Includes……… Food scraps, oil and soaps, human wastes, Industrial wastes. Waste water? 03Slide 4: Where does the water from the washer go? When you flush the toilet where does the water go? WWTP 04Introduction:: Introduction: Production of drugs is associated with generation of pollutants some of which are toxic and persist in environment Emits: odors including solvent vapors Releases: large volumes of wastewater and solid wastes which are hazardous Volume and characteristics of wastes depends on raw materials and equipment used and manufacturing processes employed. 05Stages of Treatment:: Stages of Treatment: Primary Treatment Secondary Treatment Tertiary Treatment 06Primary Treatment : O rganic materials, metals (such as zinc, silver, cadmium, thallium, etc.) acids, alkalis, non-metallic elements (such as arsenic or selenium) are generally resistant to biological processes unless very dilute and can usually be neutralized Primary Treatment 07Secondary Treatment : Secondary Treatment Activated sludge process An activated sludge process includes: An aeration tank & A settling tank 08 A generalized, schematic diagram of an activated sludge process. : A generalized, schematic diagram of an activated sludge process . 09Tertiary Treatment : Tertiary Treatment (Disinfection) Purpose: Destruction of harmful micro organisms i.e., disease causing germs 10Reverse Osmosis : Reverse Osmosis Schematics of a reverse osmosis system (desalination) using a pressure exchanger. 1 : Raw water inflow, 2 : Fresh water flow (40%), 3 : Concentrate flow (60%), 4 : Raw water flow (60%), 5 : Concentrate (drain), A : High pressure pump flow (40%), B : Circulation pump, C : Osmosis unit with membrane, D : Pressure exchanger 1 1Slide 12: 12Secondary Treatment : Secondary Treatment FROM SEWAGE TO CLEAN WATER EVERYWHERE 13Slide 14: Regards: KIREETY DINAKAR.
