Can natural polymer flocculant be used as a terpolymer in water treatment?

Natural polymer flocculant possesses an exciting prospect in water treatment due to its non-toxicity, wide source, low cost and biodegradability. In this work, we have successfully synthesized the anionic terpolymer of carboxymethyl cellulose-itaconic acid‑sodium alginate (CIS) by microwave-assisted copolymerization.

What are the advantages of anionic CIS flocculant?

In general, the anionic CIS flocculant shows excellent cost effectiveness, where the predicted operation cost of as-prepared CIS is about 60 % of conventional polyacrylamide flocculant. It also has the advantages of excellent ecofriendliness and rich raw material source, indicative its potential applications of wastewater treatment. 1. Introduction

Are natural polymers good candidates for high-efficient flocculants?

However, conventional binary systems normally have the shortcomings of large dosage, limited pH window, and complex synthesis process , , . The previous reports suggested that the natural polymers of CMC and SA were good candidates for the preparation of high-efficient flocculants.

Is organic flocculant biodegradable?

Organic flocculant, mainly polyacrylamide (PAM) in the commercial market, is difficult to be biodegraded and may cause secondly pollution due to its toxic monomer . Therefore, there is a growing interest in high-performance, low cost and ecofriendly flocculant , .

Can carboxymethyl cellulose grafted polyamidine replace polyacrylamide flocculant?

In addition, Yue et al. prepared a carboxymethyl cellulose grafted polyamidine (CMC-g-PAMD), which can be used as a new flocculant to replace the traditional polyacrylamide flocculant and has great application potential in the treatment of coal mine wastewater .

Does cnpam flocculant have a good universality for high turbid water?

The fractal dimension analysis indicated floc size increased with the enhancement of the CNC content in the CNPAM flocculant. It was testified that the flocculant had good universality for high turbid water in different concentrations and with the presence of various inorganic salts.
