The Minimalist Guide to Water Quality Analysis For Biological Nutrient Removal
Nitrogen and phosphorus are two wastewater constituents that, together, pose one of the most high-profile threats for consumers and the environment. An abundance of these elements is what ultimately leads to the formation of toxic algae in surface waters, an environmental issue that regularly gains mainstream headlines and, in some cases, poses an acute health risk to consumers.

A Small Town With Big Challenges
Aqua America water treatment plant in Tiffin, Ohio, was built in the 1920s and is situated on the Sandusky River. The plant processes 3.4 million gallons per day and was facing challenges of producing high-quality drinking water. A full measure of seasonal variety, combined with the runoff from a thriving agricultural environment, caused the small-town water facility to constantly encounter adverse conditions. In an effort to remain compliant, Aqua America enhanced coagulation, but this increased sedimentation rates and exacerbated sludge blanket depths.

Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415 Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.

Mapping And Identifying The Source Of Water Quality Issues
A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

2 Applications That Triggered The Rise Of Coriolis Flow Measurement
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process
Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

Filter Installations Remove Solids From FGD Scrubber Effluent
Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water
As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

Advances In Paper-Based Devices For Water Quality Analysis
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
LATEST INSIGHTS ON WASTEWATER
-
Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
-
Emerging state water reuse regulations are driving adoption of ozone and advanced oxidation, requiring flexible, high-performance systems to meet pathogen, trace organic, and DBP control objectives.
