Trickling filters have proven to efficiently remove pollutants from wastewater since their inception, earning recognition as a technology that will continue to serve the industry well into the future.

Handwheel or automated process valve? The worldwide trend is clearly moving towards automation, because it reduces energy and water consumption, especially rinsing water, and increases plant availability. Pneumatic automation of a fixed-bed filter is a good example of this.

Today’s wastewater stream is dramatically different than its content just a decade ago. Yet, many municipal wastewater treatment plants are functioning under older designs and are not optimized for the new reality. There are solutions to attack the problem without the significant expense of a major system or plant overhaul.

ABB’s AquaMaster flowmeters have been integral to the overall water management solution. Over 400 AquaMaster flowmeters actively serve the Bangkok Metropolitan area helping optimize the management of the water distribution network. 

Discover how AVEVA helped operate and maintain nearly 765 miles of sewer lines, and deliver more than 40 million gallons of wastewater per day to Los Angeles County sanitation district facilities. 

Flow, pressure, and temperature are the most important units of measurement when monitoring or controlling fluids in pipes. They are early indicators for problems that can have major implications for the overall business.

Would your wastewater treatment plant be able to function during a sustained loss of its aeration capabilities caused by a flood or natural disaster? What if a fire destroyed the blower house? Being prepared with a contingency plan for temporary low-pressure air will help operators prevent panic, avoid costly decisions, and minimize impact when a crisis occurs.

Duperon’s new high-capacity washer compactor was designed to tackle the most difficult challenges while reducing overall operating costs.

Learn about the early history, development, and modern-day applications of jet aerators, highlighting their significance in wastewater treatment

The surrounding areas of Rock Creek Public Sewer District of Jefferson County, Missouri experienced substantial development in recent years overloading existing privately owned wastewater plant capacities.

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.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

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.

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

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.

Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.

A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
