4. WASTEWATER ENGINEERING

5. Wastewater Engineering is that branch of environmental engineering in which the basic principles of science and engineering are applied to solving the issues associated with the treatment and reuse of wastewater @taknikinc

6. To protect health and the environment Consituents of concern in wastewater, Impacts of these consituents when waste water is pispersed into the environment, The transformation and long-term fate of thses constituents in treatment processes, Treatment methods that can be used to remove or modify the constituents found in wastewater, Methods for benefical use or disposal of solids generated by the treatment sytems. @taknikinc

7. WASTE WATER DEFINITION

8. Waste water Defined as a Combination of the liquid or water- carried wastes removed from residences, institutions, commercial and industrial establishments together suchas ground water, surface water, and stormwater as may present. @taknikinc

9. IMPACT OF REGULATIONS ON WASTE WATER

10. Regulations on wastewater drive industry compliance, leading to improved treatment practices, reduced pollution, and enhanced environmental protection, but can also increase operational costs for businesses. @taknikinc

11. HEALTH AND ENVIRONMENTAL CONCERNS IN WASTEWATER MANAGEMENT

12. Wastewater management is crucial to prevent health issues like waterborne diseases and chemical exposure. Environmental concerns include pollution of water bodies, soil contamination, and harm to aquatic ecosystems, all of which can disrupt biodiversity and ecosystem balance. @taknikinc

13. WHAT IS INDUSTRIAL WASTE WATER

14. Industrial wastewater is water contaminated by industrial activities, containing pollutants like chemicals, heavy metals, and organic matter, which require treatment before being discharged into the environment. @taknikinc

15. SOURCES

16. Agriultural waste Iron and stell industry Chemical Industry Textile Industry Pharmaceutical Industry Food Industry Pigment Industry etc...... @taknikinc

17. VARIOUS TYPES OF POLLUTANTS

18. Nutrients: Nitrogen compounds (e.g., ammonia, nitrates) Phosphorus compounds (e.g., phosphates) Organic Compounds: Oils and greases Phenols and formaldehyde @taknikinc

19. Heavy Metals: Lead (Pb) Mercury (Hg) Chemical Oxygen Demand (COD): Measures organic pollutants that consume oxygen during decomposition @taknikinc

20. Biological Oxygen Demand (BOD): Indicates the amount of organic matter that microorganisms can break down in water. Pathogens Bacteria (e.g., E. coli) Parasites @taknikinc

21. CHARACTERISTICS

22. Physical Characteristics: Color: Indicates the presence of dissolved substances or particulate matter. Odor: Often caused by organic decomposition, industrial chemicals, or sulfides. Temperature: Affects the biological activity and solubility of gases in wastewater. Turbidity: Measures the cloudiness or haziness due to suspended solids. @taknikinc

23. Chemical Characteristics: pH: Indicates the acidity or alkalinity of wastewater; critical for chemical reactions and biological processes. Chemical Oxygen Demand (COD): Measures the total amount of oxygen required to oxidize organic and inorganic substances. Biochemical Oxygen Demand (BOD): Represents the amount of oxygen consumed by microorganisms to decompose organic matter over a specific period. @taknikinc

24. Biological Characteristics: Microorganisms: Presence of bacteria, viruses, protozoa, and algae. Pathogens: Disease-causing organisms like E. coli, Salmonella, and viruses. Biodegradability: The extent to which organic matter in wastewater can be decomposed by biological processes. Coliform Count: Indicator of fecal contamination and potential presence of pathogens. @taknikinc

25. DISPOSAL OF INDUSTRIES

26. There are three Alternatives for the dosposal of Industrial Waste Surface Water Discharge: Treated wastewater is released into rivers, lakes, or oceans, following strict regulations to minimize environmental impact and protect aquatic life. Land Application: Treated wastewater is applied to land for agricultural irrigation or soil infiltration, recycling water and nutrients while recharging groundwater. Reuse and Recycling: Wastewater is treated and reused for industrial processes, non-potable applications, or recycled through natural systems like constructed wetlands, reducing freshwater demand. @taknikinc

27. PROCESS

28. Process of waste water treatment Preliminary Treatment Primary Treatment Secondary Treatment Tertiary Treatment @taknikinc

29. Preliminary Treatment Preliminary treatment involves screening and grit removal to eliminate large debris, sand, and gravel from wastewater, protecting downstream equipment and preparing the water for further treatment stages. @taknikinc

30. Secondary Treatment Secondary treatment uses biological processes to further remove dissolved and suspended organic matter from wastewater. It involves aeration tanks with microorganisms that degrade pollutants and secondary clarifiers that settle out the resulting biomass. @taknikinc

31. Tertiary Treatment Tertiary treatment is the final stage of wastewater treatment, involving advanced processes to further purify the water. It includes filtration to remove remaining solids, and disinfection using methods like chlorine, UV light, or ozone to eliminate pathogens and ensure the water meets safety standards for discharge or reuse. @taknikinc
