The Build America, Buy America (BABA) Act was part of the Infrastructure Investment and Jobs Act (IIJA), which authorized historic federal infrastructure spending that dedicated over $50 billion to water projects. Although BABA went into effect on May 14, 2022, only now are the first BABA projects in production as adjustment period waivers have mostly run their course. Some confusion over compliance remains, and [...]
It has become a standard industrial practice in medium and large-scale water treatment systems to operate multiple skids of reverse osmosis (RO) membranes . However, a persistent challenge confronts system operators: the potential for fouling or scaling issues. Interrupting the entire operation to address RO membrane performance issues becomes more than an inconvenience; it’s a substantial setback. In [...]
Membrane treatment for total dissolved solids (TDS), like reverse osmosis (RO) and nanofiltration (NF), incidentally lowers hardness and alkalinity in the process. Without further treatment, membrane permeate can be extremely corrosive to downstream environments. Remineralization, the addition of hardness and alkalinity back into the water, prior to distribution can be a successful means of reducing this corrosion [...]

Published September 2021, revised July 2024 Dirty and fouled cooling tower water often plagues maintenance teams that manage industrial cooling tower operation. A dirty cooling tower can have a detrimental effect on the overall health of the plant’s water infrastructure, leading to lower efficiencies and increased costs. Cooling water full of fine sand, grit, and biological matter can contribute to damage [...]
Due to their widespread presence in the environment and potential health risks, per- and polyfluoroalkyl substances (PFAS) have emerged as a significant topic of concern in recent years. As regulatory agencies work to tighten controls, the introduction of a new federal maximum contaminant level (MCL) for PFAS in drinking water underscores the urgency for effective water treatment solutions. We will explore the [...]
Make your startup easier with a proper layup. Protecting your system during the winter season with the right layup program will significantly reduce the amount of chip scale that will loosen up in the spring, prevent corrosion and iron-throw, and greatly extend the life of your equipment. 精东影业 offers four products that can be used for cooling layup: Protect 649, CTL-440, Cetamine [...]
Ever wondered what washing machines, healthcare equipment, smartphones, computers, and cars have in common? They all rely on the use of semiconductors, the powerful brains behind a variety of modern technology applications. However, a lot goes into making such semiconductors – from raw materials to ultrapure water – thus requiring continued investment in global semiconductor markets. Silicon [...]
As featured in Pumps & Systems Emerging contaminants, such as PFAS, are driving new treatment systems where they were previously not necessary. While it is tempting to address the need with a single treatment process, the composition of water is more than its concentration of regulated contaminants. The treatment approach should look beyond any single contaminant and consider the entire water quality to [...]
Nearly 50 years ago, the first identified cases of Legionnaires’ disease were confirmed during a convention of the American Legion in Philadelphia, Pennsylvani a. Since 1976, the study of how Legionella bacteria live, interact, and multiply in building water distribution systems continues to provide valuable information. Despite an increase in the understanding of the bacteria, the Centers for Disease [...]

Article reposted with permission by the New England Water Works Association. Abstract The Infrastructure Investment and Jobs Act (IIJA) of November 6th, 2021, includes a Build America, Buy America (BABA) clause that requires the procurement of domestic products for all federally funded infrastructure projects. This extends beyond iron and steel products to manufactured products and construction [...]
As the world’s population and living standards steadily grow, so does the need for robust and effective water- and wastewater treatment systems to support human, agricultural, and industrial water uses . Membrane separation and filtration technology is state-of-the-art and is steadily replacing traditional granular filtration in many applications. Micro-filtration (MF) is a process in the [...]
With more and more steam boilers being asked to provide intermittent service, there is renewed focus on the proper treatment of boiler systems while they are offline. In the Power industry it is not uncommon for a combined cycle plant to operate less than 30% of the time, meaning the vast majority of the time the boiler is idle. The rise of renewable power assets that have intermittent and [...]
