Development of a Field Laundry Wastewater Recycling System

Abstract : A field laundry wastewater recycling system (FLWRS) using powdered activated carbon, a cationic and an anionic polyelectrolyte, and diatomaceous earth filter was evaluated to determine the effectiveness of the process to produce recycled water for reuse in military field laundry operations. Analysis of the results of six batch runs with various treatment cycles indicated that the FLWRS batch treatment process can be operated effectively to treat laundry wastewater for recycle use in laundry units in the field. A task and skill analysis was performed to develop a training program for military laundry operators. A training course of 40 hours duration would be sufficient to enable a laundry specialist to become proficient in operating a FLWRS. No health hazard was anticipated to result from the use of detergents, bleaches, soaps, and water treatment chemicals during operation of the FLWRS. Keywords: Water reclamation; Field condition.
