| DESCRIPTION: Engineering assessment of
a water reuse and water treatment system serving 2 residential
(urban) homes. The two residences are off-grid, in that they
are not connected to either a municipal water supply or wastewater
collection system, and all wastewater is collected and treated
for a variety of uses including toilet flushing, laundry, bathing
& showers, and irrigation. The water reuse treatment process
includes primary solids removal, biological treatment (recirculating
filter), solids filtration (roughing, fine & activated carbon),
and ozonation, followed by storage. The rainwater treatment system
includes a cistern, followed by a slow sand filter, activated
carbon filter, ozone disinfection, and storage. Work carried
out included performing a technical review of the treatment processes,
designing and overseeing a monitoring program to verify the system
performance and reliability, and making recommendations to improve
the system performance and address problems with bacterial regrowth
in the system. |
