DEFINITIONS
Description:
This glossary is provided to help our visitors with some of the unique industry terminology that is often encountered in the industrial and municipal water and wastewater industries
In many ways, the Water and Wastewater industries have their own language. As industries evolve and communities grow, water quality has become a central concern. Understanding the technologies involved in maintaining water quality requires a basic understanding of the water industry's terminology. We are pleased to offer this guide of industry terms, and we hope you find it helpful in understanding the technology offered by Liquid Analytical Resource.
Glossary of Industry Terms
BOD:
Biological Oxygen Demand (BOD) is the measure of the amount of dissolved oxygen consumed by microbes to metabolize organic matter in water. BOD is used as an indirect measure of biologically degradable material present in wastewater
COD:
Chemical Oxygen Demand (COD): A measure of the oxygen required to oxidize all compounds, both organic and inorganic, in water. COD is typically measured in mg/L, which indicates oxygen consumed per liter of solution.
TNb:
Total nitrogen is the sum of all forms of nitrogen in a liquid solution. Examples include, nitrate, nitrite, ammonia-N, and organic forms of nitrogen.
TOC:
Total Organic Carbon (TOC) is a sum measure of the concentration of all organic carbon atoms covalently bonded in the organic molecules of a given sample of water.
Toxicity:
Toxicity measurement quantifies the respiration inhibition of aerobic microbes used to metabolize waste. The measurement establishes a correlation between reduced dissolved oxygen consumption and the presence of toxic substances. This measurement is especially important to protect nitrification / denitrification processes in biological waste treatment.
TSS:
Total Suspended Solids (TSS) is the measure of combined settleable and non-settleable solids in wastewater. TSS is a measure of the concentration of solids in suspension, which correlate to the amount of treatment required.
