Decontamination of water using low-cost technology for municipal wastewater treatment for safe irrigation reuse is provided. More specifically, wastewater is decontaminated by coagulation/flocculation followed by biological filtration while incorporating, in several stages, wastes from other industries such as ceramic kiln dust and biochar. Ceramic kiln dust and alum are used in a coagulation/flocculation process which is then followed by biofiltration using a biochar material.
