Introducing Claros Water Intelligence System From Hach

Changing regulations, unpredictable influent levels, and instrument downtime are all problems plant operators encounter. Without a clear picture of their water or data, operators face uncertainty about efficiency and compliance. Imagine the time savings, cost reductions, and peace of mind that a complete “water intelligence system” could provide. Claros™, the Water Intelligence System from Hach®, focuses on instrument, data, and process management to help reduce uncertainty and increase operational confidence.

Best Practices For SCADA Application Development: Sizing Pages For Differing Screens
By Andrew Harvie, Trihedral Engineering

A commonly encountered challenge is to develop pages that can be used on many screens where those screens may vary greatly in size, aspect ratio, and resolution.

Achieving Ultrapure Water
By Sun Chemical Advanced Materials

It may sound intimidating, but water that has been treated to “ultrapure” condition is more than necessary in many applications. This highly cleansed product is a fundamental part of many industrial operations, from the medicine we need to get well to the power we rely on in our daily lives. But, as the name implies, it’s no small task to get average influent to the ultrapure level.

Sanitation District Improves Operations And Reduces Costs With Ovation
By Emerson Process Management, Power & Water Solutions

A five-year plan prepared by SRCSD identified the challenges associated with a rapidly expanding service area while meeting increased environmental regulations. Major changes to the wastewater treatment plant computer system were required to overcome these challenges.

Dissolved Air Flotation System Reduces Costs, Improves Process
By Leopold -- A Xylem Brand

When the water treatment plant in Johnstown, CO, began operating its circular clarifier systems at maximum capacity to meet summer peak demand rates, consultants recommended increasing plant capacity and using dissolved air flotation technology for their clarification process.

How To Clean And Handle pH Sensors
By Frederick J. Kohlmann, Endress+Hauser

For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged, or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

Plant Operations And Maintenance Staff Benefit 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.

Ultrasonic Level Sensors Measuring Performance

Radar level transmitter types 2290 and 2291 incorporate advanced radar sensing technology designed for high-accuracy tank level measurement in a wide range of chemical processing and water treatment applications. The addition of radar technology to the company’s existing ultrasonic and hydrostatic sensors now provides three different level measurement technologies to meet virtually any level requirement. Watch the video demonstration to learn more.

VigorOx WWT II Wastewater Disinfection Technology

Disinfecting wastewater with chemicals that produce harmful byproducts seems counterproductive. That’s why we’ve developed VigorOx WWT II wastewater disinfection technology, a peracetic-based, environmentally responsible, and economically minded alternative disinfectant to chlorine and UV disinfection.

Quantifying Water Quality Benefits Of Conservation Practices
 
By Mindy Selman, Senior Analyst, USDA Office of Environmental Markets in Conservation

Although we know that farm conservation practices, like cover crops, reduced tillage and nutrient management, as well as improve overall performance and environmental outcomes, it’s difficult to say exactly how these practices affect resources, such as water quality.
