5 The Artemis Water Strategy– Proprietary 19-Jun-14
Onsite water reclaim would save 90% of its potable water and 85% of its emissions, while saving
capacity for the city’s water infrastructure.

Pax Water
Biomimetic impeller which mixes water or sewage to minimize use of
disinfectants and ensure water quality.
Over 900 installations in the US, with initial expansion globally

Miox– Onsite disinfectant generator
Miox: On-site chemical generators for water disinfection that combine salt, water
and power to generate cost-effective disinfectant chemistries on site
Produces disinfectants in response to contaminant levels in the amount they need,
when they need it, replacing chemical disinfectants, like chlorine,
12 The Artemis Water Strategy– Proprietary 19-Jun-14
Today: Chlorine is a primary disinfectant at large-scale water treatment plants, with over 2000 facilities
using sufficient amounts to require risk management plans. A major spill would cause mass casualties.
In-Pipe Technology
Bioaugmentation: Uses the sewage disposal pipe network to process
sewage by controlled doses of cultured microorganisms
Reduces influent load on the centralized waste water plant, and volume
of sludge waste
introduces a blend of specialized, facultative, spore forming in order to
establish more sustainable microbiology in the sewer network to
improve raw wastewater quality, control Fats, Oil, and Grease (FOG)

Desalitech
Based on reverse osmosis, the gold standard conventional water filtration,
Produces 70 percent less waste water, while using 30 percent less energy

More than Energy, More than Costs: One
Casualty Per 24 convoys
For sites with no local water source, Natick Force Sustainment Systems estimates a worst case requirement
for fuel and water that include 20 times as many water trucks as fuel trucks (Monroe 2010)

Bottled water is the “default” for drinking
C-130 aircrafts deliver 7,700 half-liter bottles on every trip, a thousand gallons, or one
purification unit that generates 1,000 g/d18 Artemis Water Strategy Proprietary 19-
