Chitosan for wastewater treatment - Desbrières - 2025
Chitosan (an amino‐polysaccharide obtained from deacetylation of chitin, the major constituent of crustaceous shells and insect cuticles) presents a cationic character in acidic media allowing its dissolution, its shaping and possible ion‐exchange interactions with anionic compounds (a property applied in adsorption and coagulation–flocculation processes).
The chitosan is a good flocculant for tap water treatment because of its properties such as faster deposition rate and higher removal efficiency for COD (organic matter), SS (suspended solids), and metal ions. However, its high price limits the use in tap water treatment. In this paper, in order to reduce costs, chitosan (CTS), polyaluminum chloride (CF-PAC), and modified rectorite (Al(OH)<sub
Chitosan-Derived Iron Oxide Systems for Magnetically
Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/maghemite and/or metallic Fe), have been investigated to be used in magnetically guided water remediation processes from polycyclic aromatic hydrocarbons (PAHs). Chitosan-derived magnet-sensitive materials were first obtained by a one-step coprecipitation method, and then two carbon-derived
Key application markets covered under this study includes, water treatment, biomedicine pharmaceutics, industrial, food beverages, cosmetics, and agrochemical etc. Chitosan is used as a flocculating and chelating agent for removing various traces of metals from industrial wastewater.
Chitosan: From Organic Pollutants to High-Value Polymeric
Abstract. Chitosan is obtained from chitin by partial or total deacetylation. Considering that those polysaccharides could be readily derivatized by using not only the reactivity of primary or secondary hydroxyl groups but also the reactivity of primary amino groups, chitosans are attractive raw materials for different applications, from pharmaceutical products to water treatment.

- What are polymer flocculants & coagulants used for?
- Polymer flocculants and coagulants are widely used in industry to aid in solid liquid separations. otherwise safe. PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. The process is known as polymer bridging. Also popular for erosion prevention in irrigation furrows and on construction sites.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Does Pam degradation affect flocculant performance?
- PAM-based flocculant degradation has been mainly studied for PAMs in aqueous solutions. The degradation of PAMs results in a reduction of the molecular weight of the polymer and can adversely affect the performance of such aqueous solutions in their commercial application as flocculants.
- Are Pam flocculants toxic?
- The potential environmental hazard does not concern the PAM itself, which is generally considered as not toxic (Andersen 2005), but the products of PAM degradation and the residual AMD contained in the flocculants due to incomplete polymerization process (Labahn et al. 2010; Young et al. 2007; Caulfield et al. 2002).
