Algae show promise for removing nutrients like phosphorus and nitrogen from wastewater due to their natural absorption abilities. However, the widespread use of algae-based wastewater treatment is limited by challenges related to system footprint, mass transfer and maintaining optimal conditions…
Absorption and stripping are important mass-transfer operations within the chemical process industries (CPI). This one-page reference provides some basic information on the principles and applications of stripping and absorption in industrial chemistry settings. General operation In absorption, a solute from…
Type CG330 and CG340 gas regulators (photo) are specifically engineered to address the growing demand for low-emission solutions in industrial applications involving compressed gases, such as inert gases, natural gas and other sensitive media. CG330/CG340 regulators are designed to deliver…
The NH6000sc online ammonia analyzer (photo) is designed for installation in wastewater applications in outdoor locations. By designing the unit to have reagents conveniently located right inside the door, the bottles can be easily accessed and replaced. With reagents lasting…
Biological air-cleaning systems are an effective alternative to filtration and activated carbon in many industrial applications, especially those with ultrafine particles or highly toxic contaminants Companies must maintain high air-quality standards, both indoors and outdoors, to ensure continued quality control…
A new thermolysis technology developed by Composite Recycling (Ecublens, Switzerland; www.composite-recycling.ch) breaks down fiber-reinforced polymers (FRPs) into their fundamental constituents, enabling reuse as valuable feedstock for the creation of new composite materials. “Past efforts to recycle composites have allowed waste…
Many separation processes depend on chemical or thermal principles, such as solvent extraction or distillation, but in some cases, mechanical methods can provide effective separations with lower cost and energy requirements. Eirex (Vaughan, Ont., Canada; www.eirex.ca) has developed a proprietary…
At Aquatech Amsterdam 2025, this company is launching the new Mytex H5L ultrafiltration (UF) membrane (photo), which includes no per- and polyfluoroalkyl substances (PFAS). The water treatment industry faces increasing pressure to develop alternatives to polyvinylidene fluoride (PVDF) membranes, which…
Olivine, a magnesium-iron silicate mineral, is common in the earth’s subsurface, and can sometimes contain other valuable elements, such as cobalt, manganese and nickel. Olivine has been explored as a possible sink for atmospheric carbon dioxide in carbon-capture methods that…
These powders are designed for thermal spray applications This company’s WallCarb™ HVOF (high-velocity oxygen fuel) tungsten carbide powders are designed for thermal spray applications (photo) and are engineered to provide dense, hard coatings with exceptional wear and corrosion resistance. These…
