FACTS ABOUT ON BOARD TREATMENT USING
TYPE I LECTRA/SAN.ECT AND LECTRA/SAN.MCT
The Lectra/San MC treats waste in two distinct ways by:
1. Reducing solid waste by high speed maceration to indiscernible particles.
2. Oxidation of waste matter that destroys odors, bacteria and viruses by
hypochlorous acid. The ability of the Lectra/San MC's control board to sense
proper conditions ensures the same level of treatment each time.
SCIENTIFICALLY PROVEN EFFECTIVENESS
In 1997, a series of studies were undertaken by the Department of Veterinary
and Pathology, University of Sydney, Australia. The test determined the
effectiveness of the Lectra/San EC's (to be replaced by the LST/MC) ability
to destroy the hepatitis A Virus (HAV). Results of the lab test resulted in
the following comments by the Virologist; this system is effective and will
remove 78-98% of viruses from fecal material, as HAV is one of the most
difficult viruses to destroy by chemical sterilization, a higher rate of
removal for other enteric viruses can be expected when using this device.
The system will provide an effective viral barrier protecting any direct
users of recreational water as well as shellfish farmers and shellfish
consumers. After discharge of Lectra/San EC treated water into the water
body, the resultant high dilution factor will further minimize the effect of
viruses on the environment and human health. Overall, it is clear that the
risk of viral disease being transmitted to the community from Lectra/San EC
treated water is extremely low.
B.O.D. MYTH EXPOSED
Some correspondence has been circulated regarding the efficiency of Type I
and II MSD's and claim that Type I MSD's represent 20 year old technology.
The Type I MSD that our company manufactures was conceivably 20 years ahead
of its time when it was certified by the United States Coast Guard. It meets
or exceeds the EPA's coliform effluent criteria for land based systems and
reduces BOD by as much as 75%. The following illustrate's what B.O.D.
(Biological oxygen demand) represents in the context of the marine
environment.
B.O.D.5 results from a boats holding tank contents is approximately 4000 -
5000 mg/l.
B.O.D.5 results from untreated waste is approximately 1000 - 4000 mg/l.
B.O.D.5 results from 12 oak leaves/250 ml water is 2241 mg/l.
B.O.D.5 results from Lectra/San treated waste is approximately 300 - 1200
mg/l.
B.O.D.5 results from municipal treatment is approximately (no nat. stds.)
50 - 700 mg/l.
The above figures indicate that the Lectra/San EC has a B.O.D. impact of no
more than four oak leaves
landing in the water with equally harmless effect. The use of devices that
are this effective should be
encouraged rather than not. Another factor relative to B.O.D. is volume.
There would never be enough
boaters safely discharging treated effluent in our coastal and navigable
waters to cause oxygen depletion or
algae blooms. It has never been established that treated particulate from
boats has ever caused oxygen
depletion especially in an entire states coastal waters.
Because we have owners of our USCG approved Type I MDS's in every coastal
state and many that
travel from state to state, we are obligated to defend these boater's
rights. As previously described, our
treatment process is environmentally safe and responsible and we have never
seen any logical reason or
explanation contained in any coastal states "No Discharge Area" application
to prohibit its use. States such
as New Jersey and Rhode Island apparently feel that a 100% holding mandate
is the most reliable, safe and
responsible method of addressing marine sanitation concerns. Nothing,
however, could be further from the
truth.
