Will the DIVVY purify salt water?
No, desalination typically uses large amounts of energy and specialized, expensive equipment, making it much more expensive than fresh water purification from conventional sources such as rivers or groundwater. The DIVVY purifies most contaminated fresh water sources.
Return to MenuHow much water can the DIVVY purify in one day?
The P.O.D. (Point of Distribution) can filter 4 to 5 gallons per minuter; 250 gallons per hour; approximately 2500 gallons per day with one tank; 6,000 gallons per day filtering continuously with three tanks.
Return to MenuDoes the DIVVY have a shelf life? What is the useful life of a filter?
A dry unused filter properly stored and protected from moisture and sunlight has a shelf-life of many years. Sealed in the filter housing, a dry unused filter should last indefinitely. When used continuously for water filtration, the life of the filter is 20,000 to 40,000 gallons depending on the turbidity of the water being filtered. After use at an event the filter should be discarded.
Return to MenuCan the DIVVY be stored in freezing conditions?
If the DIVVY system is stored dry, freezing conditions will not damage the system.
Return to MenuHow much does the DIVVY system weigh?
The complete DIVVY 250 three case system weighs:
211 lbs. (80 kg.)
Fill Case weights 63 lbs. (25 kg.)
POD Case weighs 84 lbs. (34 kg.)
Tank Case weighs 64 lbs. (21 kg.)
Will the DIVVY system purify swimming pool water, so we can drink it in an emergency?
Yes, all that is required is the POD (filter housing/pump/distribution lines) to filter the chlorinated water for particulate and chlorine removal. Raising the chlorine level to 4 ppm in the pool prior to filtering the water would assure purification.
Return to MenuWhat power source is required to pump and filter the water?
Both the fill pump and the filter pump are human powered, requiring no fuel or electricity to operate.
Return to MenuAre the hand pumps hard to pump for extended periods?
On a level plane, the hand pumps are easy to operate. Alternating with a second person, continuous pumping is a reasonable expectation.
Return to MenuHow long does it take to fill the 250 gallon treatment tank with the fill pump?
Two people can fill a 250 gallon tank on a level surface in 20 to 30 minutes, without much trouble. Pumping is somewhat more difficult when pumping uphill.
Return to MenuWhat chemicals do you use to treat the water in the DIVVY 250 tank?
Calcium hyochlorite [Ca(OCl)2] in a granular form is mixed with water and poured into the tank as the tank is being filled. This produces a mixture of 4 to 6 parts per million of residual chlorine considered "super chlorination."
Return to MenuWhat is the pore sizing on pre-filter? How many replacement pre-filters do you provide with the system?
The pre-filter is a 50-100µm rated, non-woven bag filter. Each DIVVY unit comes with six pre-filters.
Return to MenuIs the calcium hypochlorite already measured and in the liner?
The calcium hypochlorite is already measure but not in the liner. It is packaged in pre-dosed containers, one dose/250 gallons.
Return to MenuHow do you ensure the water is thoroughly mixed with the chlorine in the tank?
The mixing instructions include a "pre-disslove" step to make sure that all of the solid calcium hypochlorite is in solution prior to adding it to the water in the liner. A mixing container is supplied. The solutions souls be added to the tank before the tank is half-full.
Return to MenuHow many gallons will the filter remain effective for?
Each filter will remove the chlorine from the treated water for up to 20,000 gallons.
Return to MenuHow many filter cartridges does the system come with?
One filter is included when you purchase the consumables kit.
Return to MenuCan you backwash the microfilter to get longer lifespan?
Since the filter is a carbon block filter it cannot be backwashed or regenerated.
Return to MenuAre the filters completely disposable?
The filters are disposable, however special disposal rules may apply if high concentration of radioactive materials are detected.
Return to MenuCan I just buy a new filter and reuse the canister to keep costs down or is the filter and canister a monolithic design?
The canister/housing is permanent, the filter is replaceable. We have designed a cassette system to make filter change-out and service easy and problem free.
Return to MenuHow can you tell when the filter is used up and will no longer purify water?
Using the chlorine test strips provided with the system, if very low levels of chlorine are detected (0.2 to 0.4 ppm), chlorine removal is still effective. When high pressure is required to pump water through the filter it is becoming obstructed and should be replaced. Contaminants will not pass through the filter unless it is damaged.
Return to MenuWhat are the various shipping space and weight requirements for the DIVVY?
Following are approximate shipping space requirements:
100 single tank systems with consumable kits will fit into a 40’ container
50 single tank systems with consumable kits will fit into a 20’ container
100 single tank systems in a 40’ container would weigh approx. 25,000 lbs.
50 single tank systems in a 20’ container would weigh approx. 12,500 lbs.
25 single tank systems with consumable kits would be 13 pallets
2 single tank systems with consumable kits would fit on each pallet
40” x 48” x 66” @ 500 lbs.
55 triple tank systems with consumable kits will fit into a 40’ container
27 triple tank systems with consumable kits will fit into a 20’ container
55 triple tank systems in a 40’ container would weigh approx. 19,000 lbs.
27 triple tank systems in a 20’ container would weigh approx. 9,500 lbs.
25 triple tank systems with consumable kits would be 25 pallets
