A regenerable microporous adsorbent based on microcrystalline cellulose for organic pollutants adsorption

Introduction Fixed-bed column adsorption is an essential process in modern water treatment systems, widely implemented due to its continuous operation, ease of design, and applicability in large-scale systems. In this method, a contaminant-laden liquid passes through a column packed with adsorbent material, facilitating efficient contaminant removal before discharge or reuse. While effective for many pollutants, […]

Cellulose CELLETS as new type of adsorbent for the removal of dyes from aqueous media

Abstract CELLETS, a new type of adsorbent, have emerged as a promising solution in water treatment. They are particularly effective in fixed-bed column systems for removing persistent organic pollutants, such as synthetic dyes. This summary reflects research published by Suteu et al. [1]. Fixed-bed adsorption is a well-established filtration method. It allows continuous treatment of […]

Renewable Resource Biosorbents: Granulated Cellulose CELLETS 200 for Organic Pollutants Adsorption in Fixed-Bed Column Systems

Introduction Fixed-bed column techniques are widely applied in water and wastewater treatment to achieve continuous adsorption of pollutants. In these systems, aqueous effluent flows through a packed bed of adsorbent material, offering operational simplicity, easy scale-up, and consistent performance—critical features in industrial and pharmaceutical settings. However, removing dyes from pharmaceutical effluents presents unique challenges: dyes […]

Fixed-bed-column studies for methylene blue removal by CELLETS

This study investigated fixed-bed columns for methylene blue removal. It evaluated CELLETS®, a granulated spherical cellulose material, as an adsorbent in the system [1]. CELLETS® 200 has useful properties, including perfect sphericity, narrow particle size distribution, low friability, and chemical inertness. Experiments used a dye solution (9–10 mg/L, pH 4.7) with different flow rates. We […]

Ultrasound Imaging of Artificial Tongues – an approach with Cellets

The article titled “Ultrasound Imaging of Artificial Tongues During Compression and Shearing of Food Gels on a Biomimetic Testing Bench” by Glumac et al. [1] introduces a novel method to study tongue–food interactions using ultrasound (US) imaging. The study primarily aims to improve understanding of mechanical processes during oral food processing. In particular, it focuses on […]
