Study Notes
Wastewater Definition
- Wastewater is used water that contains contaminants, both dissolved and suspended, that are generated by households, industries, and institutions.
OSST and Alternative Waste Systems
- OSST (On-Site Sewage Treatment) and Alternative Waste Systems are designed to treat and manage wastewater, but OSST focuses on individual households, whereas Alternative Waste Systems serve larger communities.
Gray Water
- Gray water typically contains waste generated from sinks, showers, and washing machines.
- Gray water primarily consists of wastewater that is not contaminated with fecal matter.
Domestic Wastewater
- Domestic wastewater includes waste generated from households, including toilets, sinks, showers, and washing machines.
Components of Wastewater
- Wastewater consists of two main components: gray water and black water (which includes fecal matter).
Course Focus
- The primary focus of the course on OSST/Alternative Waste Systems is to design and implement sustainable and innovative waste management systems.
Sewage vs. Wastewater
- Sewage refers specifically to wastewater that contains human waste, whereas wastewater is a broader term that includes all types of used water.
Industrial Wastewater
- Industrial wastewater includes waste generated from industrial plants, which can contain hazardous chemicals and pollutants.
Innovative Thinking
- The goal of encouraging innovative thinking in designing alternative waste systems is to develop sustainable and environmentally friendly solutions for wastewater management.
