This powerpoint presentation begins by presenting information on the Falcon Waterfree Urinal System, including:
a waterfree urinal saves about 40,000 gallons of
water per year on average;
cartridge must be replaced every 3 to 4 months;
each cartridge costs $40 (includes sealant);
no water can be used to clean urinal;
causes odor when not maintained properly; and,
mineral deposits may form in pipes behind
urinals. The alternative Eco Cartridge is presented and includes:
manufactured by Ecotech Water, LLC;
cartridge fits in Falcon urinals;
simple design, no replacement cartridges or
sealant is needed;
each cartridge cost about $160; and,
not affected by water or cleaners. Objectives include:
collect and analyze deposits in pipes
behind urinals;
compare extent of deposition for urinals
with different cartridges; and,
perform chemical equilibrium modeling
calculations to assess potential for
precipitation to occur as a result of urea
hydrolysis. Experimental plan includes the following:
remove urinals from walls in high and low use
facilities that have used Falcon and Eco
cartridges;
take photographs to document the extent of
deposition in pipes;
collect precipitate from pipe;
analyze precipitate using X-Ray diffraction
(XRD) and scanning electron microscopy (SEM);
predict pH increase due to hydrolysis of urea
using theoretical chemical equilibrium modeling; and,
predict potential for precipitation of different
types of solid phases. Includes tables, figures.
