Rice University Fights Clogs And Saves $20K Every Six Months

With Xylem's Flygt Concertor solution, Rice University now avoids clogs and callouts caused by grease and debris, as well as costly recurring equipment replacement. 

A Small Town With Big Challenges

Aqua America water treatment plant in Tiffin, Ohio, was built in the 1920s and is situated on the Sandusky River. The plant processes 3.4 million gallons per day and was facing challenges of producing high-quality drinking water. A full measure of seasonal variety, combined with the runoff from a thriving agricultural environment, caused the small-town water facility to constantly encounter adverse conditions. In an effort to remain compliant, Aqua America enhanced coagulation, but this increased sedimentation rates and exacerbated sludge blanket depths.

Emergency Aeration LED To Oxidation Ditch Retrofit Increasing Plant Capacity

The Schwartz Wastewater Treatment Plant at Myrtle Beach, South Carolina, treated approximately 4 million gallons of wastewater per day.

Reclaimed Water: A Smart Infrastructure Move For Green Residential Developments

Reclaimed water systems, powered by MBR technology, offer developers a sustainable, cost-saving solution that meets rising water demands, eases permitting, and aligns projects with future environmental expectations.

Denitrification Filters Meet Strict, Varying Nitrogen Limits

The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood advanced wastewater treatment (AWT) plant located in Englewood. The 7886 m3/hr (50-mgd) Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75 square mile service area. Plant effluent is discharged to the Denver metro area’s major watershed, the South Platte River.

Planning For The Unknown: How To Prepare For A Catastrophic Failure Of Your Sewer System

Contingency planning for sewer system failures is often overlooked. Learn why a successful contingency plan can reduce costs, save reputations, and protect public health.

Engaging Stakeholders With Visualization And Analytics

The National Pollutant Discharge Elimination System (NPDES) permit program, created in 1972 by the Clean Water Act (CWA), helps address water pollution by regulating point sources that discharge pollutants into the waters of the United States.

WinCan Introduces Enterprise-Tier Solution

Innovative work order management and mapping capabilities give municipalities insights on sewer work and crew progress. 

NE Alabama Water District Case Study Northeast Alabama Water District (NEAW) services 15,200 connections within 2,052 square miles, resulting in a very large distribution area.

Aquapoint's AquaCell And Hallett® H-30's Perfect Partners On Zooland Project

Zooland is a resort/campground site in the Asheboro, NC, area. They have a relatively high-strength waste stream and are permitted for a surface discharge, therefore they must achieve very high effluent standards. One way or another, there was an obvious need for wastewater treatment. Cost was an issue, because private clients (especially) don’t want to spend money on wastewater.

UV Technology Offers Solution For Emerging Water Crisis

Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

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

Determination Of Hexanal In Foods Utilizing Dynamic Headspace

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.

Biosolids Odor And Corrosion Control

For more than 20 years, USP Technologies’ comprehensive biosolids odor and corrosion control solutions have been extremely effective at reducing sulfides and other odor causing compounds in municipal and industrial wastewater treatment systems.

Sewage Pump Station Level Application

The most common level application in the water and waste water industry is the infamous wet well. With its line-of-sight measurement technology, rugged sensor, narrow laser beam and virtually nonexistent maintenance requirements or on-site calibration, ABB’s LLT100 laser level transmitter answers most concerns related to wet well level measurements and makes it easy to calculate what could amount to a substantial return on investment.

Recording & Control: Online Data Recording And Control In Anaerobic Digestion Processes

Solids present in wastewater need to be safely and comprehensively treated and removed. This means not only removing toxic compounds, including both organic and inorganic materials such as heavy metals, but also eliminating any harmful bacteria present in the solids.

Dissolved Oxygen Measurement In Wastewater Treatment

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

Optimizing Air Flows To Aeration Basins

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.
