This bulletin describes the restrained length calculations for dead ends, valves, reducers, and sleeves with a discussion of several situations where economics and other factors may favor an alternate restraint method. 

Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.

Santa Margarita Water District (SMWD) is the second largest water district in Orange County, California, providing water and wastewater services to more than 155,000 residents and commercial enterprises. When a new housing development was planned adjacent to SMWD’s 9.0 MGD Chiquita Water Reclamation Plant, the District initiated plans for enhanced odor control solutions. District staff identified the primary process area (grit removal and primary clarifiers) as a significant contributor to odor emissions.

This is the second in a series of articles and case studies examining the emergence of sustainably-driven innovation within the wastewater treatment functions of the food and beverage industry as sustainability and production issues intersect and influence how companies manage their wastewater.

Although the city of Bozeman, Montana’s stormwater system has been silently producing front-page news for decades, it has typically only flowed into the spotlight because of an incident or an emergency.

Learn about an efficient and economical turnkey wastewater treatment solution for municipal and industrial applications. 

The new machines will allow larger municipal wastewater plants to use air foil bearing blower technology despite the size limitations on single units.

In this follow-up webinar Technical Product Manager, Phil Taylor will demonstrate in more detail how to select and design a Hydro-Brake using our free online design tool. The Hydro-Brake is one device that should be in every stormwater engineer’s toolbox. Hydro invented the vortex valve back in the 1960’s and has led the world in its development and design ever since.

At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

A Chicago stormwater diversion tunnel designed to correct a chronic flooding problem that has plagued the city’s Albany Park neighborhood over the past decade has been recognized for its effectiveness and ingenuity.

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

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.

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.

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

Pulsafeeder has secured a significant order for its NextStep^® series of stepper motor-driven metering pumps, specifically for use in advanced Reverse Osmosis (RO) applications. This deployment underscores the growing demand for precision chemical dosing in high-performance water treatment systems. The order includes NextStep^® NS1 and NS9 models, each selected for their unique capabilities in high-pressure and low-pressure RO environments.

Automated scraper strainers pre-filter water and wastewater to protect fragile membrane systems from damage caused by large, suspended particles, reducing maintenance and replacement costs.
