What is COD in water?
Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. Oxygen equivalent of substances (usually organic) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and contaminated water. In the study of river pollution and industrial wastewater properties and the operation and ...

Increased Demand for PureAire’s Oxygen Monitor for Nitrogen and Helium Storage
When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace. With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to workers. ...

Microbial fuel cell-based biosensors for environmental monitoring: a review
The microbial fuel cell (MFC) is an innovative technology that was initially designed to harness energy from organic waste using microorganisms. It is striking how many promising applications beyond energy production have been explored in recent decades. In particular, MFC-based biosensors are considered to be the next generation biosensing technology for environmental monitoring. This review ...

Removal of Yellow ME 7 GL from industrial effluent using electrochemical and adsorption techniques
Attempts have been made to remove toxic dye Yellow ME7GL using electrochemical and adsorption techniques. Both techniques are capable of reducing toxicity and producing clean water for reuse. The electrochemical removal is carried out at platinum electrode and cyclic voltammograms of the dye solutions have been recorded at different pH, concentrations, scan rates, etc. The adsorption of the dye ...

Use of multivariate calibration models based on UV-Vis spectra for seawater quality monitoring in Tianjin Bohai Bay, China
A series of ultraviolet-visible (UV-Vis) spectra from seawater samples collected from sites along the coastline of Tianjin Bohai Bay in China were subjected to multivariate partial least squares (PLS) regression analysis. Calibration models were developed for monitoring chemical oxygen demand (COD) and concentrations of total organic carbon (TOC). Three different PLS models were developed using ...

Sludge accumulation in shallow maturation ponds treating UASB reactor effluent: results after 11 years of operation
Polishing ponds are natural systems used for the post-treatment of upflow anaerobic sludge blanket (UASB) effluents. They are designed as maturation ponds and their main goal is the removal of pathogens and nitrogen and an additional removal of residual organic matter from the UASB reactor. This study aimed to evaluate organic matter and suspended solids removal as well as sludge accumulation ...

What is a Water Safety Plan?
Water is an essential basis in many industrial processes and a Water Safety Plan can prevent and manage threats to the water supply for those processes from the catchment to the process itself. Industries that use large quantities of water include brewery and carbonated beverage water; dairy industries; textile manufacturing; pulp and paper mills; oil and gas; the pharmaceutical industry and ...
