Point of use water treatment organizationsAbout point-of-use treatment systems
Two problems account for most of the work on Halo. Chloramine has to come out at the tap, especially for home dialysis, and hardness has to come out at a flow rate a faucet can deliver. Beside them sits a large cluster that treats no water at all and makes it from air. On Halo it spans six groups, including chloramine at the tap, softening at the faucet, and sorbent water harvesting.
Stage of development. Work on point-of-use treatment systems on Halo is split between university programs and companies. 33% of the solutions are in market. Arizona State University has the most, followed by Northwestern University. Co-development and sponsored research are the usual partnering routes, and about 58% of the solutions that state terms offer pilot engagements.
Three trends in point of use water treatment technologies on Halo
Chloramine, and specifically dialysis. Five entries remove chloramine at the point of use and three do it with light: excilamps and tunable LEDs taking 4.0 mg/L under 0.1, a household device pairing UV LEDs with ozone generated inside it, and a UV-LED module built to protect a home dialysis machine. Chloramine is harmless to drink and dangerous in a dialysate, and the clinical case is what pulls this cluster.
Sixteen ways to condense the same air. Seven use a sorbent or desiccant, nine condense or catch water passively, and the yields are quoted in the same units so they can be compared: 3 litres per square metre a day, 10 litres per square metre a day, 40 litres an hour, 5,000 litres a day. Two use no energy at all, one copying a desert plant's leaf and one retrofitting a fog mesh to a cooling tower.
The test has to work in a kitchen. Seven detection entries are built for a kitchen or a field, not a laboratory: nanobodies in a handheld kit, a nanomechanical cantilever carrying cell-free biology, viable microbes counted in five minutes with no amplification, reversible reagent-free chlorine optics. Every one of them removes a step that needs a technician.

Frequently asked questions
What are point of use water treatment technologies?
Point-of-use treatment systems covers treating water where it is drunk, not where it is supplied. It spans chloramine removal at a tap or a dialysis machine, softening built into a faucet filter, harvesting drinking water out of the air by sorbent or by condensation, compact disinfection modules, and the tests a person can run on the spot. Appliance makers, device manufacturers and off-grid operators are the buyers.
