Understanding common problems and learning how to prevent and address them can save you both time and money in the long run. Here is a brief guide to proper maintenance of your drain cleaning equipment.

Ozonation and biologically active filtration (O3-BAF) is being increasingly used to address the issue of organic micropollutants (OMPs) in wastewater treatment and potable reuse.

Advanced diagnostic tools are crucial for managing aging wastewater pump infrastructure. Trending diagnostics, ODS modeling, EMA, and MAV enable proactive, data-driven pump health assessments, helping to reduce costs, minimize downtime, and prevent catastrophic failures.

This article will explain why rain-dependent inflow and infiltration (RDI&I) measurement often fails and how to produce the level of data quality that can detect, understand, and manage it.

The AquaNereda® Aerobic Granular Sludge System (AGS) is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. This advanced nutrient removal process can reduce footprint up to 75% and energy up to 50% when compared to conventional activated sludge systems.

Driven by tight budgets and competing needs for limited CAPEX funds, wastewater treatment plants are increasingly looking to reduce their operating expenses. Many are now referring to themselves as water resource recovery facilities (WRRFs), reflecting a heightened focus on recovering nutrients, methane, and a host of other properties from their waste flows. The largest boon to date has come from thermal energy, but producing biogas comes with its own set of challenges, including accurate gas flow measurement.

Trying to balance urban population growth against water scarcity, energy consumption, and greenhouse gases (GHGs) can feel like being stuck between a rock and a hard place. Fortunately, a recent report quantifying that delicate balance offers new perspective on solutions for water professionals.

Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.

What should you consider when planning to replace the flights in your rectangular clarifier? Flights are also known as scrapers, c-channels, flight boards, drag flights, and sludge pushers. Regardless of what you call them, they serve the same purpose. Flights convey settled solids to a hopper or collection pit and push surface debris into a scum removal device in a straight-line clarifier system. Although flights may all seem the same at first glance, there are some key characteristics to think about when evaluating which type you may need for your chain and scraper system.

Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored.

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

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.

Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value.

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.

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.

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.

Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gain an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas. This includes supply planning, maintenance, resource deployment, leakage detection and the overall environment.
