This document summarizes a study on using different fibrous packing materials for sewage treatment. Three reactors were used: one filled with a blend of coffee husk and wooden chips, and two filled with coconut coir at different packing densities. The reactors were tested over 5 weeks under batch operation. The coffee husk/wood chip reactor achieved over 70% removal of COD, ammonia, phosphates and solids. The lower density coconut coir reactor performed best, with over 75% removal of all parameters tested. The study showed that locally available agricultural waste materials can effectively treat sewage as packed bed filters, providing an affordable alternative to conventional treatment methods.
