Can polyaluminum chloride coagulant be used to treat petroleum wastewater?

This work investigates the potential synthesis of cost-effective polyaluminum chloride (PACl) coagulant from waste household aluminum foil and utilization for treating petroleum wastewater (PWW), especially dissolved organic compounds (DOC, like octanol–water mixture) and nonsettleable suspended (NSS-kaolin) mineral particles.

Can flocculants be used in wastewater treatment?

The potential application of conventional flocculants, bio-flocculants and grafted flocculants in wastewater treatment has been verified and well investigated.

Why are polymeric flocculants used in industrial effluent treatment?

Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).

Which coagulation/flocculation process is used in industrial wastewater treatment?

Various research suggested the coagulation/flocculation (C/F) process as the most experienced treatment technology widely used for industrial wastewater treatment (Ghafari et al., 2009; Sajjad Haydar and Anwar Aziz, 2009; Kumar Verma et al., 2012).

What is a polymeric flocculant?

In most cases, they are derived from oil-based and non-renewable raw materials (Suopajärvi et al., 2013). Commonly used polymeric flocculants include polyacrylamide, polyacrylic acid, poly (diallyl dimethyl ammonium chloride) (DADMAC), polyamine and others (Singh et al., 2000).

Should cationic organic flocculants be more effective?

In principle, cationic organic flocculants should be more effective in dealing with negatively charged contaminants or particle suspensions, such as clay and dye.
