Proper Care And Calibration Of pH Sensors

Here are some guidelines for everyday care, regular maintenance, and periodic calibration or replacement to assure optimum performance of pH instrumentation.

Thermal Flow Meter Improves Digester Gas System Fueling Boilers For Plant Steam And Hot Water

Accurate, repeatable air/gas flow measurement under harsh outdoor conditions is essential to successful wastewater treatment operations when used in aeration or digester biogas applications. The challenge is that a relatively small number of flow meter technologies are capable of reliable measurement.

MBR Modules Help Achieve Sustainable Management Of Wastewater On Vancouver Island

The Cowichan Valley Regional District (CVRD) in Vancouver Island, Canada teamed with Toray to successfully install several membrane bio-reactor (MBR) systems updated with new technology to expand capacity.

Pasteurized Equivalent Water Treatment At Tnuva Ba'Emek, Israel

In the heart of Israel’s Jezreel Valley, Ba’emek Advanced Technologies—part of the Tnuva Group—faced a critical challenge: how to sustainably reuse water extracted from whey during dairy processing without compromising safety or quality.

ECI Solves MRO's Chromium Contamination Problem With 900 Series Monitor/Controllers

Cr(VI) is a regulated contaminant in drinking water because it can cause gastrointestinal, liver, and developmental toxicity in humans when ingested. A facility was unable to discharge to their POTW because the CR(VI) concentration in their wastewater stream was over the regulated discharge limit. 

The Value Of Wastewater Data

What follows is a breakdown of some of the key applications of real-time data access in the wastewater sector.

Improved Mixing And Fine Bubble Aeration Help To Reduce Water Exchange, Shorten Production Cycle And Increase Overall Growth Rates

Finca Empacadora de Tilapia Milagro is one of the fastest growing and successful tilapia projects in Central America since its operation started in 2015.

New Bar Screen Design Targets Heavy Vegetation In Waterways

There are a lot of trashrack designs that have capabilities to address vegetation, but until recently there has never been a solution designed exclusively for such challenges.

How To Cannibalize Your Own Technology

Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.

Eclipse Gear Pumps For Chemical Dosing: Santa Clara Regional Wastewater Facility

Read about the Santa Clara Regional Wastewater Facility, which is home to several Eclipse Pumps providing chemical dosing to municipal wastewater.

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.

WWTP Utilizes Online Instrumentation And SCADA To Keep Operating Costs Low And Effluent Quality High

Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

Panametrics Achieves Challenging Wastewater Flow Measurement On A Lined Ductile Iron Pipe

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

Wet Weather Treatment Using AquaStorm® Cloth Media Filtration

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.

Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water

As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

FLEX-TEND® Flexible Expansion Joints, Features And Specifications

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

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.

Aerated Biological Nitrogen Removal

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company
