The use of poly-aluminum chloride and alum for the treatment of partially stabilized leachate: A comparative study

Coagulation-flocculation as a relatively simple physical-chemical technique was applied in this work. Polymeric forms of metal coagulants which are increasingly applied in water treatment are not well documented in leachate treatment. This study examined poly-aluminum chloride (PAC) and aluminum sul...

Polymeric forms of metal coagulants which are increasingly applied in water treatment are not well documented in leachate treatment. This study examined poly-aluminum chloride (PAC) and aluminum sulfate (alum) in treating a partially stabilized leachate, and compared attained results in respect to the removal of chemical oxygen demand (COD), turbidity, color and total suspended solid (TSS). Series of coagulation-flocculation tests were carried out to optimize the coagulant dose, pH, and operating conditions (speed and time for rapid and slow mixing).

A concurrent optimization of speed and time of mixing resulted in a considerable enhancement in COD removal: 84.50% and 56.76% for alum and PAC, respectively. Using PAC, almost complete removals for physical parameters of leachate (turbidity: 99.18%, color: 97.26%, and TSS: 99.22%) were achieved; whereas alum showed inferior removal (turbidity 94.82%, color 92.23%, and TSS 95.92%). However, results revealed PAC is not as efficient as alum for COD elimination, where the alum dose (9.4 g/L) was about fivefold that of PAC (1.9 g/L). (C) 2010 Elsevier B.V. All rights reserved.
