Reassessing The Value Of Water Reuse In Process Efficiency

In many industrial applications, water is not part of the final product but an important process facilitator — for cooling, cleaning, etc. Like energy, it can quickly become a major expense and, therefore, an important target for cost control. As potable water supplies tighten or become increasingly expensive, reuse is becoming a more attractive alternative. Here is some of the information needed to evaluate the opportunities it offers.

Ultrasonic And Radar Level Technologies: Bringing Clarity To The Water And Wastewater Market

If your head spins after reading how amazing one level measurement technology is in comparison to another, understanding the key attributes of these technologies and their applicability to specific processes may help to clear the waters.

DO Or Die — Dealing With Aeration Basin Oxygen Deficiencies

Managing the treatment of wastewater — especially industry-generated wastewater that can elevate dissolved oxygen (DO) demands far beyond those of municipal/residential applications — is hard enough. Trying to do so during upset conditions is enough to put any water treatment professional on edge. Here are several preventive and remedial options to keep in mind before or after DO readings go haywire.

The 3 Main Reasons To Use Carbon Dioxide For pH Control

Finding ways to improve everyday processes in more efficient and productive ways is an important goal for most companies. Many water and wastewater treatment facilities use sulfuric acid when pH reduction is needed, but face safety and process risks as a result. As an alternative to sulfuric acid, carbon dioxide (CO₂) offers several benefits. 

Accurate Sludge Conditioning For Good Dewatering Results

Where should I put the sludge? There is a consensus among wastewater plant operators and other industry groups that the subject of sludge will take on more importance in the future. The reasons for this are the increasingly strict controls on discharge methods and the obvious cost burden of every cubic meter of sludge.

No More Odors Here In Bakersfield California: Replacing Calcium Nitrate With SulFeLox®

Faced with increasing costs for controlling hydrogen sulfide in its wastewater collection system, the City of Bakersfield, California commissioned an evaluation of its program in 2019.

Pump Maintenance Know-How

In this article, see if you can identify your own trouble spots and uncover potential solutions to get you back on the road to good pump health – boosting profits along the way. 

Using Bubbles To Reduce Toil And Trouble

Two innovative products leverage natural fluid dynamics, biology, and aeration principles to reduce labor and energy consumption in wastewater applications — the Lagoon Master Aerator and the Wet Well Wizard.

Maintaining Greater Value In Bar Screen Performance

Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early on in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.

Pure Oxygen Injection Into A Pipeline

The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples Total bound nitrogen (TN_b) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TN_b measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

Bridge Crossings And The Proper Use Of EX-TEND®, FLEX-TEND®, And Force Balanced FLEX-TEND Products

Of particular interest when it comes to bridges is the locating of pressurized water lines on and under bridge structures. Pressurized pipelines can present a number of unique challenges to the design engineer and utility owner.

What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

What Is Genclean Advanced Oxidation Disinfection Solution And What Is It Used For?

A non-toxic, advanced oxidation (AOP) formula of minerals chelated with oxygen and stabilized in an aqueous water solution. It is a viable option in industries and applications requiring a solution to challenging situations where high level effective sanitization and oxidation is required. Read more to learn how the Genclean advanced oxidation treatment solutions can be used in different applications.

AquaSBR Systems Above 10 MGD

This application note will explore installations of AquaSBR Systems worldwide in a variety of municipal and industrial applications. 

Dissolved Oxygen Measurement

One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Improving Compliance Through Real-Time Phosphorus Control

Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

Textile Manufacturing

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

MEGA-STOP Bell Protection System Aids In Pipe Joint Assembly

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.
