Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber

The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.

DIMMINUTOR® Protects Pottstown Equipment From Abrasion, Clogging

The Pottstown, Pennsylvania Wastewater Treatment Plant handles the wastewater generated by 15,000 area homes, commercial businesses, and industrial sites located in the borough of Pottstown and three nearby townships. The facility is rated for 15.6 mgd and treats an average flow of 7 million gallons of sewage a day.

How To Utilize pH Neutralization Systems And Adhere To Discharge Regulations

For any drinking water or wastewater treatment operation, pH neutralization is never far from top-of-mind. The regulatory standards for pH to which effluent must adhere, also known as “pH neutralization,” are central to ensuring that treatment is performed accurately and that the water or wastewater leaving a plant is safe.

Resolving Odor Complaints With Targeted Solutions Restore Community Confidence

The South Dearborn Regional Sewer District in Lawrenceburg, Indiana, provides regional wastewater treatment services for three cities and an international distillery. The 6 mgd treatment plant is located in an area of high population growth and is surrounded by many retail operations and other commercial developments. In addition, a heavily traveled state highway runs by the treatment plant.

An 8-Point Checklist Of Pressure Gauge Application Best Practices

As electronic measurement, microprocessor or computerized control, and wireless networking have worked their way deeper into industrial processes, new opportunities for accuracy, convenience, and cost-saving efficiency have multiplied. Electronic accuracy and communication have delivered performance advantages down to even the simplest functions — including pressure readings.

Wastewater Treatment Plant Reduces Energy Consumption, Noise With Turbo Blower Technology

Built in 1974, the Blue River Wastewater Treatment Plant in Silverthorne, Colorado, provides wastewater services to the communities of Silverthorne, Dillon, Dillon Valley, Buffalo Mountain, and Mesa Cortina. Faced with rising energy costs and aging equipment, the Silverthorne-Dillon Joint Sewer Authority (JSA) identified a need to replace the plant’s original multistage centrifugal blowers with new technology that would reduce energy consumption and provide steady and reliable operation.

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.

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.

Repair Or Rethink

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

Ion Exchange Resins Reduce Pollution From Refineries

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.

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.

Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise

Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

Simplify And Optimize Your Process With Level And Pump Control

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.

Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

Pile Cloth Media Filtration Effectively Removes COD And TSS From Oil Refinery Wastewater

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.
