Modern wastewater treatment processes are not designed to operate with inorganic solids in the waste stream. While grinders are typically a cost-effective method for protecting the pumps at pump stations, there are other critical junctures within a treatment plant where operators have an opportunity to protect valuable assets with screening technology.

Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

When the discussion turns to requirements for “explosion-proof” pumps, many people rely on word of mouth, past practices or even old wives tales it seems. By Kevin Clemons

Read how Aerzen’s next-generation hybrid screw blower redefines what it means to merge performance with sustainability in wastewater aeration systems.

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.

Because recent advances in plastic materials and processing have led to a new generation of plastic piping systems to handle challenging water and chemical environments, it is important to understand why some older piping choices might no longer be the best bet. Here are some key reasons to consider new plastic-piping choices for municipal and industrial water/wastewater applications in a whole new light.

The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.

In this white paper, learn how real-time monitoring of ammonia (NH₃) and nitrogen (N) in wastewater treatment plants (WWTPs) can be a game-changer for optimizing treatment performance and energy efficiency.

With Xylem's Flygt Concertor solution, Rice University now avoids clogs and callouts caused by grease and debris, as well as costly recurring equipment replacement. 

Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases of the SBR process include a cycle of fill (with or without aeration), react, settle, decant, and idle. Today, successful flow control strategies have made SBRs state-of-the-art technology. SBRs are commonly used today and are especially beneficial for many industrial applications.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

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.

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.

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.

For more than 20 years, USP Technologies’ comprehensive biosolids odor and corrosion control solutions have been extremely effective at reducing sulfides and other odor causing compounds in municipal and industrial wastewater treatment systems.

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.
