The facility, which handles .55 mgd of wastewater from domestic sources as well as from a Veterans home, was getting deluged with rags and other debris spilling over into various areas of the wastewater treatment process causing frequent maintenance headaches. The debris was constantly clogging up the pumps and had to be removed manually. Of particular concern was the solid waste from the Veterans home, which contained enormous quantities of cooking grease. Once the grease entered the waste stream, it congealed into large blocks that coated and clogged the lines, increasing down time and maintenance headaches.

Wastewater treatment facilities use multiple processes and a variety of equipment to produce water clean enough for reuse. Each process within the treatment train may serve a different function yet use the same or similar equipment. In such cases, standardizing equipment may be beneficial.

Scum is not a substance that anyone in a wastewater treatment plants wants to deal with. Scum, the greasy substance that floats to the surface of clarifiers, gets nastier as it accumulates. Some smaller wastewater treatment plants mix their scum back into other processing streams while other larger plants treat their scum separately. The City of Fort Worth takes a unique approach in managing its scum and now turns what was once a liability into an asset.

Valves are one of the most common assets in the process industry, spanning all verticals. Chemicals, refineries, and petrochemicals, however, will find improved valve health diagnostics useful for critical valves and controllers in their plants, while upstream and midstream oil and gas companies may be focused on much larger, critical valves like pipeline or subsea valves. Using Seeq, process manufacturers are able to implement a condition-based monitoring analysis to monitor valve health across an entire fleet. Engineers can utilize the historical data to accurately create a predictive maintenance forecast and preemptively detect valve failures before they occur.

Water quite literally flows through every facet of life, being the key element for everyone and everything on Earth. The world’s population is increasing at 1.1 percent (roughly 83 million) every year, an incredible and alarming rate straining the world’s fresh water supply. The increasing pressures between what humanity demands and what is currently available emphasizes the importance of conservation.

Canada’s Region of Peel is a permanent home to more than 1 million people and a temporary stopover for another 20 million air travelers who pass through Toronto Pearson Airport each year.

Are you not getting the aeration performance you expect? Perhaps you’re not even aware that your system is lagging. In this age of doing more with less — practically a mandate considering high water-quality demands coupled with tight municipal budgets — operational optimization is essential. Since mechanical aeration is a cornerstone of successful wastewater treatment, it’s a natural place to focus your optimization and troubleshooting efforts.

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.

The Cibolo Creek Municipal Authority (CCMA) provides regional wastewater services for the area northeast of San Antonio, Texas and serves the surrounding communities. After years of frustration in dealing with severe problems with plugging of the pump suction lines that led to frequent pump rebuilds, they turned to the 10K Muffin Monster. The 10K Muffin Monster now plays an integral role in this water reclamation plant’s system by grinding the primary sludge and debris that is pumped to the digesters.

The question often arises “Can you really eliminate thrust blocks using joint restraint?” This bulletin will provide you with the information needed for you to realize the answer to that question is “yes”. For many years, thrust blocks have been successfully used in distribution systems all over the world. Thrust blocks, however, are not without limitations.

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.

Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

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.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.

There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
