Due to the dynamics of liquids and gases flowing through elbows, valves, pumps, and other pipeline structures, every flow-meter methodology has its own design limitations. Unlike Venturi meters, pitot tubes, orifice plates, and other devices, V-Cone meters provide highly accurate and reliable readings with minimal straight-pipe length restrictions and virtually no maintenance, in pipe sizes up to 120”.
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.
Wastewater can be both corrosive and abrasive. To ensure reliable and cost-effective pump operation, it is important to select a wastewater pump made from the most suitable material for your wastewater.
With the ongoing concern about water quality in Alaska, Philip Downing, the Remote Maintenance Worker for South East Alaska Regional Health Consortium, offered a new approach to a plant’s ability to continuously monitor and adjust treatment processes in response to changes in raw water quality.

On the small island of St. Thomas, the Mountain Top condominium complex had a big problem: its sequencing batch reactor (SBR) was failing. And a replacement treatment system was needed quickly, because residents relied on the recycled wastewater for use both in toilet flushing and landscape irrigation.
A U.S. light aircraft manufacturing company uses an alkaline cleaner followed by an alkaline de-smutter, rinse, acid de-smutter (possibly using potassium permanganate), rinse, alodine, and a final rinse. The three 1,700 gal rinses are dumped approximately once each week, or more often, based on the pH.
When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
UV treatment has only recently become widely adopted in the water and wastewater treatment industries but the benefits of sun exposure for water purification have been acknowledged for thousands of years.
A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.
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.
The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.
The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.
To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past.
The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. In many hydrocarbon recovery and water processes, degassing is necessary in order to minimize environmental impact, improve operating efficiency, avoid process issues and help protect system components.
The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.
A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Nutrients in the environment from excess nitrogen and phosphorous can result in negative impacts on water quality. EPA is improving nutrient management by incentivizing the development of low-cost technology solutions, such as nutrient sensors, in collaboration with USGS, USDA, NIST, NOAA, and the U.S. Integrated Ocean Observing System (IOOS).
Tertiary reverse osmosis (RO) wastewater recycling has become a suitable solution to augment water supplies to combat water scarcity across the world. RO desalination in tertiary wastewater processes has proven to provide a cost efficient way to reuse water for both municipalities and industrial organizations.
When designing anything, whether it be a machine, a program, or a process, there are always a few key factors to consider that can determine the validity of the design. Over the past decade, water and wastewater treatment methods have been focused on developing solutions for the water scarcity epidemic with additional emphasis on sustainability. Seawater reverse osmosis (SWRO) plant design requires careful analysis with several criteria to consider in the design of these systems.
To make informed decisions about how to limit exposure to cyanotoxins, utilities need information to select and implement a comprehensive and technically sound management approach. The Water Research Foundation (WRF) has been actively involved in developing effective innovative solutions to help utilities address this challenge and protect public health.
Your body is a machine. Like most machines, you have to properly maintain your body in order for it to function properly. Along with regular cleaning and checkups, you also have to be cognizant of what food you put into your body or else it won’t work at its maximum potential. An industrial reverse osmosis water treatment system actually works in quite a similar way.
Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.
The Integrated Fixed-Film Activated Sludge (IFAS) process is typically installed as a retrofit solution for conventional activated sludge systems that are at or beyond capacity.
