The terms that appear in our proposals and in most water tenders — explained for the person who has to take the decision, not the person who has to build it.
A formal, documented run that a system must pass before handover. It is the moment the supplier's claims become the buyer's evidence — ask for one in any water contract, not only ours.
A treatment stage where contaminants stick to the surface of a medium such as activated carbon or a molecular sieve. It removes organic compounds, chloramines and taste-and-odour contaminants before water reaches the RO membrane.
Producing drinking water by condensing moisture directly out of ambient air, rather than drawing it from a lake, river, aquifer or municipal main. Aarvish units operate in humidity as low as 20% and at temperatures approaching −40 °C.
Water saltier than fresh but less salty than seawater — common in some groundwater. It requires reverse osmosis to be made potable; conventional filtration will not do it.
What a system costs to buy versus what it costs to run. For remote water, OPEX is usually the number that decides the case — removing trucking and fuel changes the cost of water, not just its availability.
Holding equipment at its design-minimum temperature for a sustained period to prove it still starts and runs. Aarvish units undergo a 72-hour soak at −40 °C before shipping approval is granted.
The raw water produced when an AWG cools air below its dew point. It is not yet drinkable — it goes on through filtration and reverse osmosis first.
The proportion of time a system actually runs versus sits idle. It drives real output and wear far more than a peak-output figure on a datasheet does.
A structural simulation that predicts how an enclosure behaves under load — transport shock, wind, snow, thermal stress — before anything is built.
Wastewater from sinks, showers and washing, as distinct from sewage. Aarvish reclamation modules recover greywater and process water back to potable quality.
Wind and solar generation combined with battery storage, so a system runs continuously without fuel. It removes diesel deliveries, generator emissions and on-site fuel storage from the equation.
A boil-water or do-not-consume notice in place for more than a year. Canada has lifted 132 nationally since 2015; the ones that remain are largely in communities where conventional infrastructure cannot reach.
Operating with no connection to the electrical grid. For most of the communities Aarvish serves this is the normal condition, not an edge case.
The two streams leaving an RO membrane. Permeate is the purified water you keep; concentrate carries the rejected contaminants. In an Aarvish system the concentrate is routed to reclamation rather than discharged.
Water that is safe to drink. The word matters in procurement: water can be clear, filtered and still not potable.
Forcing water through a semi-permeable membrane so that dissolved contaminants are left behind. Aarvish membranes filter to 0.0001 µm and reject 99.9% of dissolved solids, heavy metals, nitrates, pharmaceuticals and biological agents.
Measurements sent automatically from the system to somewhere else. Aarvish units report water quality, system health and energy production over a satellite link, so monitoring does not depend on local connectivity.
The combined weight of everything dissolved in water — salts, minerals, metals — usually in milligrams per litre. A headline number for water quality, and one of the values Aarvish telemetry reports continuously.
The share of a period during which a system is available and producing. Aarvish designs to a 96% annual uptime target, with remote monitoring in place to defend it.
An operating target in which nothing is released to ground or surface water. Aarvish reclamation recovers 85% of process wastewater for re-treatment, which is what makes this achievable in environmentally sensitive regions.
No term matches that. Try a shorter word.
If a term in a proposal — ours or anyone's — is doing work you cannot check, ask. We would rather explain it than have it agreed to.
