BIOLOGICAL PROPERTIES OF WATER IT HAS ALL INFORMATION REGARDING BIOLOGICAL PROPERTIES OF WATER

BIOLOGICAL PROPERTIES OF WATER

1. BIOLOGICAL PROPERTIES OF WATER [TYPES] Microbial Contamination: Water can harbor various microorganisms, including bacteria, viruses, and parasites, which can pose health risks if consumed. Sanitation systems aim to prevent microbial contamination of water sources, often through processes like filtration, chlorination, or UV disinfection. Biofilm Formation: Biofilms, which are communities of microorganisms that adhere to surfaces, can develop within water distribution systems. These biofilms can affect water quality and contribute to the spread of pathogens. Proper sanitation practices and regular maintenance of water infrastructure are essential for preventing biofilm formation. Nutrient Availability: Water serves as a medium for transporting nutrients essential for microbial growth. In sanitation systems, managing nutrient levels is important for controlling the proliferation of microorganisms and preventing issues like algal blooms in water bodies. pH and Chemical Composition: The pH and chemical composition of water can influence microbial growth and the effectiveness of sanitation treatments. Monitoring and controlling these factors are essential for maintaining water quality standards and ensuring the safety of water supplies.

2. Microbial Contamination ALGAE: Plant like organism which live and grow in water Over growth is called algae bloom which causes turbidity and may produce harmful toxins Algae is one of the largest consumption of carbon dioxide hence positive side is production of oxygen

3. BACTERIA: These are microorganism. CLASSIFICATION Bacteria from soil – surface water run off mixes into water bodies Natural waste bacteria Bacteria from sewage/ animal by product Coliform group of bacteria E-coli is the common type that originates from animal intestine DISEASES Typhoid Cholera

4. VIRUSES These are infectious agents that needs a host to multiply Example – Rotavirus , adenovirus, hepatitis virus WORMS Also helminths – parasitic organism Transmitter through fecally contaminated food / water Example – roundworms [ Nematodes ], Flatworms , Rotifiers
