Plant Operations And Maintenance Staff Benefits From New Headworks

The high cost of maintenance and unsatisfactory performance of the aging equipment in the Bonnybrook headworks made it clear that significant changes were in order. The older poorly performing headworks allowed screenings to pass to the downstream process units causing operational and maintenance problems. By installing the Huber RakeMax® and matching WAP washpress, Calgary’s process performance immediately improved.

Navigating The Partial-Pipe Flow Challenge

One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.

Desalination Technology Transforms 650 m3/day of Abused Industrial Wastewater

From Blowers To Controls: The Path To Smarter Aeration

Aerzen’s latest hybrid blowers and intelligent control systems deliver unmatched energy efficiency, adaptive performance, and lower operational costs—helping wastewater plants modernize aeration for a smarter, more sustainable future.

MBBR System Implements Nitrogen Reduction Plant Improvements

Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

6 Wastewater Treatment Problems Jet Aeration Can Solve

This article delves into the six most prevalent wastewater treatment issues in industrial treatment plants and explores how jet aeration and jet mixing technology can effectively mitigate them.

Winter Maintenance For Trickling Filters

As winter approaches and cold weather sets in, both the air and wastewater temperatures of your trickling filter can drop to the single digit area, so we want to bundle it up to prevent it from catching a “cold.” It is critical to preserve heat within the filter so the bugs are happy, healthy, and keep working hard to clean up the wastewater that humans produce. Here are a few measures you can take to keep the bugs happy and your trickling filter efficient:

Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization

Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

Building Resilient Water Treatment: How Ozone Systems Help Utilities Prepare for Extreme Weather

Ozone systems build resilience into water treatment. They ensure utilities remain chemically self-sufficient, allow fast recovery from power outages, and handle rapid water quality shifts.

TASKMASTER® TITAN® To The Rescue In Picturesque, Cobleskill, New York

The wastewater treatment plant in picturesque Cobleskill, New York, was unable to process the wastewater generated by the town’s 4,678 year- round residents. The buildup of plastics, rags, trash wrappings and other debris was regularly clogging the system, necessitating frequent cleanings.

Best Practices In Moist And Wet Gas Flow

The Wet Gas MASSter sensor is for use in applications that have a high level of moisture or condensation present in the gas flow stream that cannot otherwise be removed.

'TOTEX' Is Key When Purchasing Instrumentation

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.

Municipal Real-Time Water Quality Monitoring

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

Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

Orion DUAL STAR™ Quick Start Note - Nitrate In Water & Wastewater The Thermo Scientific Orion DUAL STAR meter shows the results of both input channels simultaneously.

TOC Monitoring In Process Return Condensate

Industrial power plants or co-generation power plants utilize steam for industrial purposes other than power production.

Chlorine Measurement In Wastewater And Regulated Discharge Requirements

Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients.

Pile Cloth Media Filtration Removes 97% Of Microplastics From Wastewater

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.

Advances In Paper-Based Devices For Water Quality Analysis

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
