Measurement Of VigorOx® WWT II Peracetic Acid In Wastewater
2/2/2016
Accurate measurement of peracetic acid (PAA) in wastewater is critical for the proper dosing of PAA to meet target microbial reduction targets and to ascertain the concentration of PAA in the plant effluent to meet local regulatory water quality standards. This edition of Wastewater Disinfection Forum discusses the current state of the art in the measurement of PAA in municipal wastewater.

Water Quality Testing: Solutions From Catchment To Waste
3/22/2018
Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused. Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle is crucial. Whether in lakes, pipes, or bottles, we can accompany you with our range of instruments, test kits and applications for your water and wastewater needs.

The Difficulty With Accurate Testing For BOD In Industrial Stormwater Runoff
3/18/2020
Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an adverse pollutant in natural waterways where healthy ecosystems are protected. Several states have identified BOD as a pollutant-of-concern related to runoff of stormwater from areas that are associated with industrial activities, and, as a result, have specified water quality limits or objectives for BOD in stormwater discharges from industrial facilities.

The Key To Accurate Waste Gas Flow Measurement
4/20/2020
Wastewater treatment facilities have a tremendous opportunity to utilize the biogas they generate to lower energy costs and minimize odors. However, the practice isn’t as widespread as it could be, as the precision gas flow and methane content readings required to optimize the process often clash with the misconception that biogas is messy and difficult to measure reliably. With the proper equipment, it is possible to accurately measure biogas to cut emissions and reduce or eliminate the energy bill.
