Onsite water reclaim would save 90% of its potable water and 85% of its emissions, while saving

capacity for the city’s water infrastructure.

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
