Sanitary System: Electro Scan
In many countries boat with permanent installed toilets, are
required to have onboard a Marine Sanitation Devise (MSD) that
either stores human waste until it can be transferred ashore, or
reduce the coliform count to such low levels that discharged
sewage poses no public health hazards even in populated harbor.
More than 3
miles from the coast is legal to discharge raw (untreated) waste
overboard, either directly from toilet or by emptying the
three-mile limit, it is illegal to dump raw sewage. In these
areas, boaters my discharge waste only if it has been treated by
an onboard treatment device (Type I or II MSD). Otherwise, it
must be contained on board in a Type III MSD, and transferred
ashore at a pump-out station (which in many cases, sadly, means
it will get a modest amount of treatment before finding its way
back into the water).
Marine Sanitation Device Type I (MSD I) :
Convert waste water less than 1000
per 100 milliliters and no visible
Sanitation Device Type II (MSD II): Coliform bacteria count of
less than 200 for 100 milliliters and suspended solids not great
than 150 milligrams per liter. Treatment system that use heat or
chemicals to break down waste and reduce the bacteria count to
specific level. The resulting sanitized is legal to dump
overboard and most areas include in the 3 mile coast limit, but
not in non discharge zones.
have installed Electro Scan onboard WAYRA.
I lectro scan™ is a U. S. Coast Guard Certified Type I Marine
Sanitation Device for use on inspected and
uninspected vessels 65 feet (19.7 Meters) and under. It must be
operated within areas that are not declared a Federal No
Discharge Zone (NDZ) by the U.S. Environmental Protection Agency
(EPA). This is applicable for all U.S. territorial waters inside
the three mile limit. electro scan is designed for recreational
use and accommodates most marine toilets
it can be used with one
or, in some cases, two toilets. The electro scan installed on
Wayra is 12 V DC.
Each time the toilet is flushed an equal amount of previously
treated waste is discharged. The electro scan does not
pump waste out. The flushing action of the toilet moves the
waste through the electro scan.
The first chamber macerates to reduce particle size. The
second chamber mixes to ensure uniform treatment of
contents. When the tank is full with salt water the electrode
plates, when electricity is applied, generate bactericide in
When first activated both motors come on and run for the
entire cycle. The user then has 35 seconds to flush toilet.
After 35 seconds the electrode is energized to begin the
treatment process which lasts for approximately 2 minutes.
