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 polyacrylamide & poly Aluminium chloride be used in wastewater treatment?

Field applications indicate that polyacrylamide (PAM) and poly aluminium chloride (PAC) are capable of dealing with diverse types of wastewater [4, , , , ]. The flocs formed by applying PAC are small, loose, and unstable. Yet flocs generated by cationic PAM are tight and more stable .

How to make poly aluminum chloride?

2.1. Preparation of poly aluminum chloride from kaolin 10 g of dried kaolin added to 35 ml of HCl (36%), sp.gr. (1.15), reflex for 3 hrs., at 150 °C, then, filtrate of the hot solution through filter paper (Whatman 40), the filtrate has animation as PAC ™.

Why is kaolin used in poly aluminum chloride production?

For numerous reasons, including affordability, accessibility, sustainability and eco-friendly, the production of poly aluminum chloride utilizing kaolin and other natural materials is regarded as an innovative technology , , , , .

What is the chemical formula for poly aluminum chloride?

As a polynuclear former, poly aluminum chloride (PAC) is a complex inorganic compound made of aluminum and progressive chlorination of the hydroxyl ion. Al x (OH) y Cl 3x-y or Al (OH) a Cl b (SO4) c is the chemical formula for PAC, where (a+b+2c) =3 and a >1.05.

Is aluminum chloride neutralized?

Commonly, aluminum chloride has been neutralized to produce PACls. PACls typically include high levels of polynuclear aluminum hydrolysis products, such as Al 13 , , . As a polynuclear former, poly aluminum chloride (PAC) is a complex inorganic compound made of aluminum and progressive chlorination of the hydroxyl ion.
