Ocean Plasma as received from Dominion Diving in Halifax, NS is pure Ocean Water, harvested 35 miles out to sea, at a depth of 100 feet, during an incoming tide, in calm weather that has lasted at least three days. See the Ocean Plasma harvesting page for further harvesting details.
When received, the Ocean Water is pristine and pure. It arrives in totes of 1,000 Liters or more. Each batch of 1,000 liters must be filtered with a dual filtering system to remove all impurities. This filtering process is also combined with an ozone purification process that eliminates all bacteria and other pathological agents or organisms. This document documents the filtering and purifying process.
The filtering criteria are:
A nominal sedimentary filtration with two tandem pleated filters, one of 1.0 microns and the next at a nominal 0.4 microns. A single pass is sufficient.
Then, a second much more stringent filtration process takes the seawater solution through a 1 micron and a 0.2 micron filter. This is an absolute process (down to an absolute of 0.2 microns)meaning that no molecules larger than 0.2 (1/5) of a micron (µ or µm = micrometer) will remain in the filtered solution. An Ozone purification process, using medical oxygen, is added during all filtration processes. This process eliminates any possible pathogens. A micro-biological test is performed by an independent lab on the resulting each batch of cold-filtered and purified seawater solution to establish its purity.
The lab tests check for the total absence of ...
a.) Microbes
b.) Yeasts
c.) e-coli
d.) P. aeruginosa
e.) Staphylococci
f.) Salmonella
Only when the Lab tests prove absolute microbial purity can Ocean Plasma processing continue towards a final product.
Preparation:
| 1.) Using a fork lift, stack two full totes one on top of the other with the valves facing the work area, if possible.
2.) Prepare an empty tote near the stack of full totes so that the output of the filtering unit can flow from the full top tote into the empty one.
3.) Open the small or large top cover to allow air to enter the tote as the seawater is drawn from the full tote tote into an empty one. If you don't do this you will implode the plastic tote liner!
4.) Keep the tote valve closed but remove any locking straps (tie-wraps?)
5.) Attach the large stainless steel valve to the tote valve. Make sure that this valve is closed.
6.) Attach the large green hose connector to the large s.s. valve's connector. Secure properly.
|
| 7.) Attach the other end of the large tote output hose to the input side of the pump motor
8.) Open the yellow pump valve to establish water flow through the pump
9.) Push the grey venturi onto the filter output hose (click on image below) so that the short inner end points toward the filter unit and the longer inner side points into the empty tote
10.) Attach the venturi properly to the tote so that it cannot get lost into the tote by accident.
|
| 11.) Set up the Ozone generator as per this photo (click to enlarge).
a.) One end of the clear plastic hose should connect to the output of the medical oxygen bottle (must be full before you start) and the other connects to the oxygen side of the Ozone generator.
b.) The rubber hose connects to the grey venturi nipple and the other end is pushed onto the ozone output of the Ozone generator. Attach the rubber hose to the venturi with a small tie wrap.
12.) Recheck all connections before proceeding.
Make sure that the Ozone generator is plugged into an electrical outlet.

Water Flow (First Filtration)
12.) Slowly open the tote valve, and then open the large s.s. hose valve that connects to the tote valve. Water will start flowing to the pump. Make sure the yellow pump valve is open.
13.) Check for any leaks and correct them. Crack open both vent nuts at the top of each filter. Wait for water to come out of the top. Flip the pump switch a couple of times to force seawater into the system and see if water comes out from the vents. When it does come out of the first (primary) filter, close the vent finger tight. Check the second (secondary) filter vent and when water spurts out, close the vent finger tight. The water should now flow into the empty tote. Do not proceed until this is a fact. Dry any water puddles at the filter - keep things neat and clean!
14.) When water is flowing steadily from the full tote into the empty one, open the main valve of the oxygen cylinder using the supplied slotted key. Dial the oxygen bottle pressure regulator to obtain a flow rate of 1/2 liter per minute.
| 15.) Switch on the Ozone generator by pushing the small red button under the generator housing. Click the image to enlarge and see where the arrow points.
Note: The Ozone generator must never run without a running oxygen input otherwise it gets damaged.
16.) Carefully and prudently smell the running water flow - it should be strongly reeking of ozone.
17.) Hook up a shop vacuum cleaner to suck the ozone away from the work area if the situation calls for such measures.

| Water Flow (Second Filtration)
When the first tote is empty (don't run it completely dry - it will cause an airlock in the pump) - check the time it took to empty the tote. 20 minutes to one half hour is normal. A closed loop filtration can be employed as shown in the three photos here to complete the filtration / purification.
Each tote should run at 1/2 liters of oxygen flow per minute for a total of at least one full hour.
Run the filtration as shown here also for additional totes to be processed. When switching totes, turn off the generator and oxygen to conserve oxygen. Also, turn off the tote valve and following large s.s. hose valve and the pump switch. Be careful with the rubber hose that connects to the venturi - it comes off easily. Secure it with a tie-wrap if necessary.
