Applications of Chitosan in Wastewater Treatment By Petronela Nechita In the last time, the use of natural additives that are biocompatible, are biodegradable, have low toxicity and are from renewable resources attracted attention of many researchers due to their high ability to retain different pollutants from wastewaters.
The application of chitosan nanocomposites in wastewater treatments, including removal of heavy metals, dyes, organic, and emerging contaminants were reviewed. The antimicrobial activity of chitosan nanocomposites was also included.

Tidal Clear™ is our high molecular weight chitosan acetate, and is available in ready-to-use liquid solutions that are optimal for stormwater and wastewater. Incorporating chitosan into your water treatment system reduces operating costs, increases throughput, and enables sludge upcycling.
Biochar-Assisted Wastewater Treatment and Waste
Biochar is the solid byproduct of pyrolysis, and its cascading use can offset the cost of the production and its use in application such as soil remediation. A wide variety of research on biochar has highlighted its ability to absorb nutrients, metal and complex compounds, filter suspended solids, enhance microorganisms’ growth, retain water and nutrients as well as increasing the carbon

Application of chitosan, a natural aminopolysaccharide
Application of chitinous products in wastewater treatment has received considerable attention in recent years in the literature. In particular, the development of chitosan-based materials as useful adsorbent polymeric matrices is an expanding field in the area of adsorption science.
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 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).
In this review, after a brief description of the use of chitosan in wastewater treatment and the basic principles of chitosan-based hydrogels and biosorption, we focus on some of the work
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 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.
- 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.
- What is ionic polyacrylamide (PAM)?
- Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.
- Can polyacrylamide contribute to residual polymer formation?
- Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
