VOC Control: Solvent Recovery Versus Oxidation
Regenerative thermal oxidizers (RTOs) are commonly used for abatement of volatile organic compounds (VOCs), but in some cases, solvent-recovery systems can realize significant economic and environmental benefits In the field of industrial air-pollution control, the regenerative thermal oxidizer (RTO) is…
Drum Screen Evolution: Eliminating Trunnion Wheels Reduces Downtime and Cost
Through a trunnion-free drum-screen technology, fine screening applications with high solids loading can achieve their goals while controlling costs and reducing risk For fine screening and small-particle removal in applications like wastewater treatment, few technologies offer as much value as…
Falling Films in Vessel CIP Applications
Applying an understanding of flow regimes and turbulence to clean-in-place (CIP) processes can optimize CIP cleaning efficiency, reducing water, solvent, energy and chemical use, while maintaining cGMP cleaning performance For vessels and bioreactors in bioprocessing applications, designing clean-in-place (CIP) cycles…
Microwave irradiation and ion exchange lower cost of battery upcycling
Approaches for recycling cathode active materials from used lithium-ion batteries generally face a tradeoff wherein recovering materials with the widest range of possibilities for re-use, such as pyrometallurgical methods, generally require high energy and long process times, while direct-recycling approaches…
