Utilizing Calcite or Limestone Contactors for Remineralization Downstream from Membrane Treatment

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 [...]

The Importance of Keeping Your Cooling Towers Clean

As featured in Process Cooling.

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 [...]

Addressing PFAS Contamination in Drinking Water: Navigating the New Federal Drinking Water Rule

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 [...]

Cooling System Lay-Up

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. Kurita America offers four products that can be used for cooling layup: Protect 649, CTL-440, Cetamine [...]

Strengthening Kurita’s Water Treatment Business in the North American Semiconductor Market

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 [...]

Holistic Approaches for Your Contaminant of Concern Using Pre-Treatment

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 [...]

Reducing the Growth of Legionella Bacteria in Distributed Water Systems

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 [...]

Navigating Build America, Buy America (BABA) as Service Providers

As featured in the Journal of the New England Water Works Association.

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 [...]

The Sometimes Maddening Question of Boiler Lay-Up

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 [...]

Considerations for Refurbishing Your Media Filter

As featured in WaterWorld Magazine.

For media filters, the phrase “if it ain’t broke, don’t fix it” often prevents necessary, routine maintenance from occurring. Due to budget constraints and competing priorities, refurbishing your filter may be the last thing on your mind, especially when it is still removing contaminants below regulatory standards. However, waiting too long can result in lost efficiency or decreased [...]

Film-Forming Amine Resurgence Leads to Water Treatment Harmonization

As featured in Process Heating.

Depending on your boiler or heating system, a one percent reduction in fuel used to heat water could mean likely saving tens of thousands of dollars over a year of operation. As well as it would curtail hundreds of tons of CO 2 emissions from burning fossil fuels. Preserving longevity of critical industrial boiler equipment while striving to reduce total cost of ownership continues to be a major driving force of [...]

Risk Assessment Revisions for Distributed Building Water: A Recent Update to Your Water Management Plans

Updated Water Management Requirements According to estimates from the Centers for Disease Control (CDC), over seven million Americans get sick from diseases spread through water each year. The CDC indicates that out of these millions of people, 120,000 are hospitalized, and the associated treatment costs involved exceed three billion dollars. Utility water systems in hospitals have been under close study [...]
