Certain Properties of Laboratory Greywater and Shipboard Non-Oily Wastewater and Permeates.
Abstract
Waste water samples were collected from experimental greywater treatment filters. Greywater source was from the U.S. Naval Academy, Annapolis, MD; from DD977, USS Hayler, or from CG51, USS Thomas S. Gates, stationed at Norfolk, VA. The waste was analyzed for general and specific properties and constituents. The total dissolved solids ranged from 546 mg/l to 8140 mg/l, and the chemical oxygen demand from 122 mg/l to 1160 mg/l. The concentrations of protein, carbohydrate, surfactant, as well as organic and inorganic ions were highly variable, and showed no correlation between themselves or with the bulk characteristics. The molecular weight range of material passing through the filtration system was determined, revealing that the majority of material is very small, with greater than 50% passing an ultrafilter of 3000 molecular weight cutoff. The efficiency of the filtration process was examined, showing that about 60% of COD was removed, as well as essentially all of total suspended solids.
