Laboratory Results of Laundry Wastewater Treatment.
Abstract
This report relates the results of the chemical treatment of laundry wastewater in the lab, using different chemical coagulation and flocculation compounds i.e., iron, aluminum and lime used separately and together. The flocculation procedure using iron was discussed in detail. Also lime or lime and aluminum processes were tested. Finally the report suggests that the best way for chemical treatment is by using just only one chemical coagulation compound (Aluminum Sulfate) with polyelectrolytes as a flocculation aid (WT-2700) to lower the cost and simplify the design of the treatment plant. The optimum dosage of aluminum sulfate was estimated, and the best condition of the reaction especially for pH and temperature of the solution were fixed. Also includes the filtration process, the ideal sand filter and the designing of the media bed, the using of polymers as filtration aids. The type of filter structures were discussed. The gravity and pressure filters were concerned. The results of this effort indicate that the recycling of laundry wastewater at Army installations is not cost effective at the present time. (Author)
