March/April 2021: From the Editor

April 21, 2021

Welcome to our March/April edition, which focuses on the oil and gas industry. At a time when the market faces many uncertainties, this month's features offer insights that can save operators time and money.

Our cover story, on page 10, comes from Eleftheria Mavredaki, Sam Toscano and Graeme Orr from SUEZ Oil and Gas, and it covers how to prevent halite formation in produced water. They write that, “Dealing with halite mitigation in gas fields, either onshore or offshore, requires a more sustainable treatment strategy. This is what upgraded halite inhibitors can offer nowadays. These highly biodegradable chemistries can eliminate scale risk and reduce operational costs associated with water washes.”

On page 12, Dr. Ming Yang, a principal consultant at TÜV SÜD’s National Engineering Laboratory, discusses best practices for oil-in-water measurement.

“Oil-in-water (OiW) measurement is a specialized subject, relevant to water and wastewater treatment,” Yang writes. “However, unlike many other parameters, OiW is a method-defined parameter. Without a method specified, figures of OiW concentration can be misleading to say the least.”

On page 16, veteran contributor Amin Almasi covers fundamental sludge processing components. He writes, “Poorly designed sludge treatment and management systems can lead to undesirable consequences, such as plant shutdowns, financial loss, penalties and operational problems. Familiarity with the basic sludge management and treatment components outlined here will help operators ensure these systems are not overlooked.”

This issue’s case study comes from Michael Bourke, director of sales and marketing at Wigen Water Technologies. Bourke details how Wigen installed a reverse osmosis and ultrafiltration system under the tight space requirements of Con Edison facility in New York City.

“Con Edison operations and the East River station have been very happy with the system performance and quality of water delivered to their mixed bed demineralization system, which is consistently well below the target conductivity of less than 50 µS/cm,” Bourke writes.

On page 20, we have collected an assortment of new products for your consideration, as well as two product spotlights focusing on pipes and fittings and valves and actuators, both on page 19.

I’m also happy to welcome several new members to our Water Technology magazine editorial advisory board: Dr. Ming Yang, Brad Buecker, Nidal Samad, Matthew Wirth, and Trever Ball. I want to thank all the new board members for their commitment and hard work.

We also extend our gratitude to this issue’s contributors and to you, our readers. We hope you enjoy this edition of Water Technology. WT
