Study Notes

Water Resource Depletion and Wastewater Treatment

Global water resources are diminishing rapidly, threatening depletion.
Discharge of untreated wastewater contaminates remaining water sources.
Efficient water use and wastewater treatment are crucial for human survival.
Treated wastewater can be reused in various applications after meeting specific standards.
Water resources are decreasing rapidly globally, contributing to a potential depletion crisis.
Untreated wastewater discharge pollutes existing water sources.
Efficient water use and wastewater treatment are essential to conserve water resources and prevent pollution.
Treated wastewater can be reused after meeting quality standards.

Types of Domestic Wastewater

Domestic wastewater originates from household activities (kitchen, showers, toilets, laundry).
Domestic wastewater is categorized by composition:
- Black water: Mixture of human feces and urine.
- Yellow water: Human urine and flush water.
- Brown water: Mixture of human feces, flush water, and potentially paper.
- Grey water: Water used in kitchens, bathrooms (excluding toilets) for tasks like washing, showering, sinks, baths, and laundry.
- Other: Spillages and cleaning activities.
