Study Notes
Impurities in Water
- Water can contain physical, chemical, and biological impurities.
- Physical impurities include sediments which can affect taste, odor, and clarity.
- Chemical impurities include metals and nutrients can impact health and lead to waterborne diseases.
- Biological impurities include microorganisms which can cause waterborne illnesses.
Waterborne Diseases
- Contaminated water can transmit diseases such as cholera, typhoid, and dysentery.
Collection of Water Samples
- Water samples are collected to assess water quality.
- Techniques and protocols are crucial for collecting representative samples.
Water Analysis
- Physical analysis assesses water's clarity, color, odor, and turbidity.
- Chemical analysis measures pH, dissolved oxygen, heavy metals, and nutrients.
- Bacteriological analysis tests for pathogens and indicator organisms like E. coli.
Water Quality Standards
- Indian Standards (I.S.) and World Health Organization (WHO) guidelines set permissible limits for various water quality parameters.
Flow Diagrams and Layouts of Water Treatment Works
- Water treatment works utilize a series of processes to purify water from its source to distribution.
Intakes
- Intakes are structures used to draw water from its source.
- Types of intakes: surface, subsurface, and direct intakes.
- Intake location is carefully chosen to minimize contamination.
- Design criteria ensure effective intake operation.
