Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

We’re past the midpoint of the Texas legislative session and the bill filing deadline is behind us. Because the legislature only meets for five months every other year, there’s a lot to accomplish in a short span.

Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

Until recently, it was difficult to find an optimal meter for the harsh conditions that can occur during water transfer in oil and gas applications. The good news is that an effective, accurate, and rugged meter is emerging as an alternative.

Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of chemical processes. The central refining process is atmospheric distillation whereby the crude oil is fractured into different components based on their differing boiling points. Each of these fractions will be sent along to separate process to be turned into the different oil products. Therefore, remediation of refinery wastewater from these different processes can be quite complex.

Parkson recently had a very successful pilot test at the facility of a bio-feedstock supplier of waste products turned into fuel. The Rotoshear® unit, equipped with a .060” wedgewire screen, successfully removes solids directly from Industrial Waste Hauling trucks to recover grease. Screening this material before it enters the receiving station allows the facility to focus on proper treatment of the industrial wastewater rather than the expensive downtime to drain and clean their receiving pond.

Wastewater utilities have a new opportunity to turn their sludge (biosolids) into something special.

American Laboratories, Inc. is a leading manufacturer of enzyme products for many food, dietary supplements, nutritional and industrial applications. The company has grown steadily, currently operating three facilities in Omaha, Nebraska. To keep pace with this expansion, the company realized, some years ago, that a more efficient way to process the enzyme material was necessary. After examining their options, they made a decision to purchase a Franklin Miller DELUMPER® Crusher 1077 S4.

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.

Keeping pace with changing industrial wastewater treatment demands can raise multiple issues of oxygen demand, capital cost, and operating expense, often without the flexibility of taking basins out of service to upgrade to new levels of performance. Fortunately, there are alternatives for delivering more oxygen to treat more water.

Deep in the Israeli desert is an academic institute that is building peace in the region by putting nature at its center. The Arava Institute, in partnership with Ben Gurion University, brings students from Israel, Palestine, Jordan, and around the world to find common ground around environmental problems and build trust — and peace — from there.

The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.

The Egyptian Ethylene and Derivatives Company (ETHYDCO) is a joint venture company established with the purpose to produce Ethylene, Butadiene and their derivatives (Polyethylene, Poly Butadiene).

What would happen if there was an emergency in the U.S. that caused radioactive material to contaminate drinking water supplies? What steps could your utilities and government take?

The Toxic Substances Control Act (TSCA) requires reporting, record-keeping, testing requirements and restrictions for chemicals of concern, including PFAS. To help meet these requirements, U.S. EPA researchers have developed a chemical category-based approach to help prioritize PFAS for further data collection efforts.

The arrow is pointing up for the water and wastewater industry, thanks to funding and technology advances, but certain work remains to ensure the promise is fulfilled.

Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

Wastewater utilities have a new opportunity to turn their sludge (biosolids) into something special.

This is the second post in a two-post series on the 2017 Tax Cuts and Jobs Act (“TCJA”), with which developers and water companies see the return of a tax policy with negative consequences for development.

Electromagnetic meters have increasingly become the instrument of choice for municipal utility and industrial water measurement applications where highly accurate flow measurement is critical. Also known as mag meters, these devices contain no moving parts, so they are both reliable and virtually maintenance-free. However, if a mag meter’s liner is torn or delaminates, it can lead to serious problems and major expenses.
