High performance, cost-effective and ecofriendly flocculant

Natural polymer Flocculant Alginate Carboxymethyl cellulose Wastewater treatment 1. Introduction Flocculant can agglomerate and enlarge the suspended particles and colloids in wastewater, thus accelerating the aggregation and precipitation of pollutants to achieve the purpose of solid-liquid separation [1].

A cost-effective anionic flocculant prepared by grafting

Moreover, the estimated treatment cost of CAL is 68.3% lower than that of commercial anionic PAM. The prepared anionic CAL flocculant has the characteristics of environmental safety, excellent flocculation performance and cost-effectiveness, which shows great potential in the field of dye wastewater treatment, and also provides a feasible way

flocculation of both anionic and cationic dyes in aqueous

Flocculation of both anionic and cationic dyes in aqueous

The tailored amphoteric grafting flocculants CMC-g-PAM were prepared successfully, and proved to be efficient in eliminating both anionic and cationic dyes from water under the corresponding optimal conditions. To obtain the better removal efficiency, the PAM grafting ratio of the copolymers should be controlled in a suitable range.

Evaluation of Anionic and Cationic Pulp-Based Flocculants

The developed water soluble, anionic and cationic bio-PELs were characterized and tested as flocculation agents for a textile industry effluent treatment. Initially, jar-tests were used to tune the most effective flocculation procedure (pH, flocculant dosage, etc.).

Water Soluble Polymer Flocculants: Synthesis

There is no universally accepted formal definition for flocculation, but it is generally accepted that flocculation is the aggregation of solids achieved with the help of high molecular weight polymers through the formation of bridges between particles.

Lignocellulose¨Cacrylamide¨Ccarboxymethyl cellulose copolymer

Dye wastewater causes great harm to the natural environment and health. To prepare a high-efficient and cost-effective flocculant to deal with the cationic dye wastewater is still an enormous challenge. In this paper, an anionic copolymer of lignocellulose, acrylamide and carboxymethyl cellulose (LAC) was designed and synthesized by microwave-assisted copolymerization technique. The synthetic

Dyeing auxiliaries play an important role in the determination of the final dyeing quality. The formation of additional complexes with dyes and auxiliary agents enhances the exhaustion of dyes on textile substrates. For aqueous-based dyeing, dye auxiliaries such as chelating agents, dispersing agents, leveling agents, electrolyte, pH control agents, and surfactants form complexes with the dye
