FOR IMMEDIATE RELEASE
NEWLY PATENTED TOILET "SEPARATION" TECHNOLOGY REDUCES WATER CONSUMPTION
BY 40 TO 95% AND ENVIRONMENTAL POLLUTION BY 100%
Introduction
Nationally and internationally, pressure is increasing to introduce
nutrient reducing, water conserving and recycling measures for
sustainable residential and small community water/wastewater treatment
systems.
Newspaper, magazine and television reports of inadequate water quality
and quantity are being reported daily. Since 9/11 community water
supplies and reserves have become potential targets for bio-terrorism.
Systems utilizing rainwater catchment, cisterns for storage, blackwater
separation, greywater treatment, filtration and disinfection
technologies for partial or total reuse represent a logical and
economical option for reducing and eliminating these pressures.
Methods
One-pint-of-water-per-flush gravity or vacuum porcelain toilet fixtures
are plumbed to the Bio-Matter Resequencing Converter (BMRC). The
toilets utilize a hand or foot pedal operating flushing mechanism that
rotates a ball/trap device, which also controls and adjusts the water
level in the toilet bowl to prevent staining or streaking.
Utilizing the vacuum flushing toilet model allows flexibility in
locating the BMRC instead of having to design the house or facility
around the system. For existing homes that do not have basements or for
homeowners who do not want or do not have a location where an above
ground building can be located, an underground concrete vault is
recommended. The structure can be insulated and heated for cold
climate installations and maintenance personnel can easily service the
Systems without having to enter the home.
Utilizing Mother Nature's principles of aerobic decomposition
(composting), the automated BMRC biologically converts 90 to 95 percent
of all toilet and kitchen garbage disposal organic wastes into odorless
carbon dioxide and water vapor. The BMRC can handle up to 12 adults
full-time and can accommodate larger numbers for brief periods of time.
Greywater is plumbed to a series of separate polyethylene settling and
treatment tanks. This System consists of a Surge Tank for flow control,
an Aeration Tank to produce aerobic conditions and a Clarification Tank
to return the settled solids back to the Surge Tank. An extremely
energy-efficient (67 watt) air compressor provides an abundant amount
of air to continuously provide oxygen and circulate the greywater. By
separating the toilet flow from the greywater, the estimate for water
consumption and greywater treatment is reduced from 75 of co-mingled
wastewater to 40 gallons of "Separated" greywater per person per day.
The estimated treatment capacity of each greywater treatment system is
400 gallons per day. Additional systems can be installed in parallel
for greater flows.
The Greywater Treatment System (GTS) process aerates and biologically
treats the organics in the greywater. The Filtration and Disinfection
System (FDS) mechanically treats and produces an effluent that can be
safely discharged to reduced in size subsurface absorption beds or it
can be reused for landscaping or irrigation purposes.
If the greywater is to be totally recycled, it flows into a storage
tank that is aerated with ozone to kill bacteria. High and low level
float switches control the operation of the Household Water Filtration
and Recycling System (HFRS) to make potable water utilizing a high-
pressure pump, which directs the ozonated water through filters,
ultraviolet light, ultra and carbon filtration, another ultraviolet
light and reverse osmosis.
The processed water is then stored in the potable water storage tank,
which supplies water to the entire household utilizing another pump,
ultraviolet light and a .2-micron filter. Because water used for
toilet flushing is evaporated in the BMRC and not connected in any way
to the greywater treatment system, makeup water is re-supplied from a
rainwater cistern, well or city water supply. An installed
monitoring/control panel is programmed to activate pumps and valves for
maintenance. The panel reports to the central monitoring facility if
any alarms are activated or any of the components are in need of
service or replacement.
Treated Greywater Effluent and HFRS Results
Testing by Olmsted County, Rochester MN of the treated greywater
effluent documented that separation and greywater treatment reduced
water consumption by 40%, achieved greater than a 94% reduction for TSS
and BOD5, greater than 83% reduction in total organics, over 90%
reduction of total-N and a 1000 fold reduction in Fecal Coliform.

Conclusions
Psychologically, people may not think that they would like to reuse
their
own greywater for bathing and especially for drinking. Considering
that
all
water has been wastewater at some point in time, Separation Technology
combined with the described tested water treatment technologies
provides
for
the total treatment of the greywater and produces safe water quality
for
recycle in landscaping/irrigation or "Bottled" water quality for total
household reuse. Pricing ranges from $8,000 to separate the toilet
wastes
and reduce water consumption by 40% to $25,000 for the complete
technology,
which will treat, filter, disinfect the greywater and reduce water
consumption by 60 to 95%. Considering the complete technology
eliminates
the need to drill an expensive well, which may have no or low flow or
bad
water quality, design and construct large soil treatment areas for
septic
systems or expensive collection, distribution and treatment facilities
for
piped water and sewer systems, this technology is less expensive, safer
and
healthier for the homeowner and the environment.
