Production of Alum from Aluminium Drink Cans Waste for Water Treatment

The graphite furnaces atomic absorption spectrophotometry (GFAAS) technique has been previously used to quantify the aluminium (Al) content in soft drinks made from aluminium cans over the course of a 12-month storage period. The current research aimed to determine the efficacy of alum obtained from waste soft drink cans compared to the alum obtained from local markets in treating water from Shatt al-Arab, Basrah, Khorramshahr, and Abadan, Iraq. The Shatt al-Arab Treatment Plant in Basra governorate is the subject of the investigation. A raw water sample was taken from the water treatment facility at the Basra governorate (Shatt al-Arab water), and household aluminium waste soft drink cans were obtained from scavengers in the Basra neighbourhood. The extraction of alum from domestic aluminium wastes was done in a lab experiment. Required statistical analysis was done, and a comparison was made. The study showed the volume of water was equal (350 mL) in both samples before coagulation but was slightly high in the standard article (320 mL) after coagulation. The water turbidity is the same in both groups before coagulation and greatest in standard after (82 NTU) coagulation. The solids are highly dissolved in the standard group (258 ppm) after coagulation than prepared (170 ppm). The prepared material shows high conductivity (20) than the standard (15.59). The prepared material is highly acidic (1.2 pH), with high calcium (160 mg/L), sulphate (2720 mg/L), potassium (525.6 mg/L), sodium (132.66 mg/L), and low chloride (2130 mg/L), and magnesium (92.34 mg/L) compared to standard material from the market. The study concludes that there are no relevant differences in using the alum that is available in markets for the same purpose and that is prepared.
