What is characterization of wastewater?
A characterization of the wastewater, which provides a wide variety of information regarding the type and concentration of the contaminants present, must be carried out to determine the type of contamination concerned. …
What are the characteristics of domestic waste water?
Physically, domestic wastewater is usually characterised by a grey colour, musty odour and has a solids content of about 0.1%. The solid material is a mixture of faeces, food particles, toilet paper, grease, oil, soap, salts, metals, detergents, sand and grit.
What are the chemical characteristics of wastewater?
Chemical Characteristics • Wastewater contains chemicals such as nitrogen, phosphorus and levels of dissolved oxygen as well as others that may affect its composition and pH rating. Highly acidic or alkaline wastewater is probably trade waste and will require pre-treatment before discharge to the sewer.
How do you measure wastewater characteristics?
Biological characteristics are determined with bioassays and aquatic toxicology tests. Both the biochemical oxygen demand (BOD) and chemical oxygen demand (COD) tests are a measure of the relative oxygen-depletion effect of a waste contaminant. Both have been widely adopted as a measure of pollution effect.
What are the 9 wastewater characteristics?
Basic Characteristics of Wastewater
- Physical Characteristics. · Turbidity. · Color. · Odor.
- Chemical Characteristics due to Chemical Impurities. · Chemical Oxygen Demand (COD) · Total Organic Carbon (TOC)
- Biological Characteristics due to Contaminants. · Biochemical Oxygen Demand (BOD) · Oxygen required for nitrification.
What are the physical characteristics of water?
Physical characteristics of water quality
- Color – pure water is colorless; colored water can indicate pollution.
- Turbidity – pure water is clear and does not absorb light.
- Taste and odor – pure water is always tasteless and odorless.
What are the unique characteristics of water?
Unique properties of water
- Water is polar.
- Water is an excellent solvent.
- Water has high heat capacity.
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Water is less dense as a solid than as a liquid.
What characteristics of water make it so important to life?
Water is essential for all living things. Water’s unique density, high specific heat, cohesion, adhesion, and solvent abilities allow it to support life.
What are two characteristics of water that make it so important in living organisms?
Its four key properties – thermal properties, ability to act as a universal solvent, cohesion and adhesion – help support the life processes and habitats of virtually all organisms. Water is a polar molecule, meaning its charge is unevenly distributed with a delta negative oxygen and 2 delta positive hydrogens.
