Biologically Active Filter Technology Applications For Wastewater Treatment Upgrade

Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading to tertiary treatment and the removal of BOD, TSS and Total Nitrogen.

Creating Stability For The Energy Revolution Takes Ability

ABB provides an extensive selection of proven measurement and analytical products and solutions for power generation industry applications.

MABR: Familiar WWTP Principles, Better Results

Wastewater treatment plant (WWTP) designers and decision-makers tasked with finding more cost-effective performance for challenging applications want new options. Here is how flat-sheet membrane aerated biofilm reactor (MABR) technology tweaks the chemical and biological functions of conventional activated sludge (CAS) processes to reduce energy consumption and operating expenses (OPEX) in demanding applications.

ABB Pumps Up Water Sustainability With Smart Technologies

Few resources are as vital to our health and well-being as clean water and sanitation. What we easily take for granted would not be possible without myriad sophisticated technologies – to be found from water extraction and purification plants, through pumping and delivery, to the efficient removal of wastewater and its processing.

Self-Tuning System Provides Big Leap In DO Control

The City of Cumberland (MD) wastewater treatment plant could see wild swings in its dissolved oxygen (DO) levels until it replaced its air control system with Aerzen AERprocess, an intelligent airflow control system. Now, the city enjoys vastly improved DO control in individual zones and across the entire process, as well as significant savings on its energy bills.

Screenfield Retrofit Saves Greenwood Lakes WRF Time And Money

Greenwood Lakes Water Reclamation Facility, located in Seminole County, Florida- just north of Orlando, treats approximately 694 million gallons of wastewater each year.

Improving Water System Performance: A Continuous TOC Measurement Technology To Enhance Real-Time Process Control This article discusses real-time Total Organic Carbon (TOC) tracking in the water purification process and the importance of rapid, continuous, and reliable TOC monitoring for real-time critical water release. Submitted by Mettler-Toledo Thornton

Basics Of Mixing By Submersible Mixers

Understanding the basics of mixing not only helps wastewater treatment plants (WWTPs) to meet treatment goals but can also reduce operating costs.

Three-Dimensional ROI: Getting More Than Just Dollars From Your Smart Water Network

When it comes to digital transformation via ‘smart city’ technologies for leak detection or sewer overflow prevention, utility needs inevitably overlap with the economic and infrastructure interests of other city operations. Evaluating operating efficiencies in the context of three-dimensional (3D) ROI can uncover practical ways to drive greater dividends for all concerned — utilities, society, and the environment around them.

A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater

This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

An Ideal Aeration System For Aquaculture Corporations

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Removal Of PFCs With Activated Carbon

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

A Non-Intrusive Solution For Measuring Wastewater Flow In A WWTP's Iron Pipes

A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

Panametrics' Technology Proves Key In Supporting Serbia's Flood Prevention Strategy

A water management company in Serbia used Panametrics' ultrasonic flow meter technology for stormwater management, ensuring reliable measurement and accuracy in challenging conditions. The technology allowed for live monitoring of water transfer and reduced the risk of flooding.

Protecting Pumps From Dead Head Conditions

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

Reduce SBR Maintenance Costs With Jet Aeration

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

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.

Filter Installations Remove Solids From FGD Scrubber Effluent

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.

Comparison Of Ultra Low Range Total Chlorine Residual Limits Of Detection And Quantitation Across The Water Industry

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.
