Abstract:

Recreational vehicle (RV) owners commonly use chemical toilet additives containing formaldehyde to minimize odors from their wastewater holding tanks. The purpose of this study is to determine the character and treatability of this wastewater using conventional septic tank-drainfield systems at highway rest areas. RV wastewater is a high-strength waste. Mean concentrations from 72 samples are 5-day biochemical oxygen demand (BOD5) 3110 mg per liter, chemical oxygen demand (COD) 8230 mg per liter, total suspended solids (TSS) 3120 mg per liter, and volatile suspended solids (VSS) 2640 mg per liter, with a formaldehyde concentration of 170 mg per liter. The average volume per vehicle is 62 liters. Because RV wastewater is highly concentrated, sludge and scum accumulation and pumpout interval should be considered in addition to hydraulic residence time when sizing septic tanks for RV waste. A model for sludge and scum accumulation is developed based on the concept that some organic material in sludge and scum is readily degradable and compactible, some is degradable and compactible with extended residence time, and some material is inert and not compactible.
