Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

Refinery Treats Groundwater Contamination While Saving Precious Facility Space

A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant.

Fuel And Fuel Additives

Importance Of Filtration in Water Treatment For Process Water & Wastewater Reuse

Filtration is very important for many commercial/industrial process water & wastewater reuse applications. In reality, pumping wastewater from somewhere like a refinery, food/beverage, textile or oil produced water application requires pre-filtration due to high amount of suspended solids in these typical applications. In fact, there are typically several filtration and treatment steps in these applications to ensure that the treated water meets the required discharge or reuse standard. In addition, filtration in water treatment ensures reduced operating cost on downstream polishing water treatment systems.

Pumps Improve Wastewater Treatment In A Sugar And Bioethanol Plant

In the sugar and bioethanol industries, robustness and reliability of the equipment are of paramount importance. The XFP pumps were taken into operation in 2013 and have been running continuously since then, without any interruption or specific maintenance.

A Lid For Every Pot: Retrofitting To Meet New Aeration Challenges

Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO₂ and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.

Sustainable Clarification In Food And Beverage Operations

Companies within the food & beverage industry generate significant quantities of wastewater each day. For example, a 16 oz. can of beer is about 90-95% water; however, to make that can, beer producers utilize approximately 7 times this quantity. About 2/3 to 3/4 of the water is typically discharged as wastewater to a municipal sewer system.

Beware Of Problematic Wastewater Aeration Additives

Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.

Lessons From Nestle's Zero Water Facility

Under pressure to avoid using Southern California’s endangered groundwater supply, Nestlé has announced plans to convert a Modesto milk factory into a “zero water” facility capable of extracting water from the materials it manufactures and reusing it for industrial processes.

How The Middle East Is Transforming Its Power And Water Industry

Global demand for power and water is accelerating — and the Middle East is no exception. A burgeoning population combined with multiple industrial diversification programs is fueling a boom in power and water projects. During the first three quarters of 2017, about US$30 billion of major power contracts and US$20 billion of water projects were awarded across the region. In 2018, the figure is looking more like $60 billion with the two sectors combined.

Keeping A Lid On It: Identifying And Intercepting Potential Cooling Water System Upsets

A wide range of industrial operations rely on cooling systems to function. And, in turn, these systems require cooling water to function. So, it stands to reason that a wide range of water treatment issues need to be considered and addressed so that cooling water system upsets are avoided and everything continues to run as it should. Oftentimes, an efficient industrial operation depends on efficient monitoring and treatment of cooling water.

Water And Power Generation Remain A Balancing Act Amid Tightening Regulations

A recent survey digs into the treatment aspects of water in the power industry, revealing how electric utilities are responding to concerns over regulations and volumes of use.

Power To The Women: For Women's History Month, NREL Celebrates The Powerful Women Of Water Power

This article is the first of two in a Women’s History Month series that showcases a handful of the National Renewable Energy Laboratory’s (NREL's) outstanding women researchers in water power.

The Energy Reality Behind Cape Town's Water Crisis — And Why The U.S. Should Care

In Cape Town, South Africa, the countdown is on for Day Zero when water taps in the city of 4 million people are expected to run dry.
