What LibertyCES's vendor documentation shows
AXEON's XP-Series page carries a useful chemical-to-problem reference table that belongs on an open page: iron removal via hydrogen peroxide or chlorine (eliminates staining/metallic taste); hydrogen sulfide control via chlorine or potassium permanganate (removes rotten-egg odor); pH adjustment via soda ash or caustic soda (prevents corrosion, improves treatment efficiency); disinfection via chlorine or UV; scale prevention via polyphosphates; manganese removal via potassium permanganate (prevents black staining). Antiscalant injection is named separately. The vendor also describes a complete well-water treatment train worth publishing as a reference sequence: pressure tank integration, then retention tank for contact time, then post-carbon de-chlorination, then backwashing filters. Dosatron adds the electricity-free proportional alternative across three orders of magnitude of flow.

Real Specifications
| Dosatron D132 flow/injection range | 35.2–132 GPM; injection ratios from 1:30,000 to 1:100 depending on model (D132MZ30000/5000/1) | dosatron.md |
| Dosatron D400 flow/injection range | 110–400 GPM; injection range 0.003%–0.5% (1:30,000 to 1:200) | dosatron.md |
| Dosatron lineup flow-capacity spread | D07 (0.02 GPM min) to D400 (400 GPM max) — three orders of magnitude across the lineup | dosatron.md |
| AXEON XP-Series output/turndown | 4–30 GPD output, 20:1 turndown ratio, peristaltic metering pump | axeon-water-filtration-ion-exchange-disinfection-injection.md |
| Dosatron Venturi proportioner | Self-cleaning polypropylene, built-in check valve preventing back-fill into the concentrate tank | dosatron.md |
Dosatron's Venturi proportioner includes a built-in check valve specifically to stop line water from back-filling into the chemical concentrate tank — a real backflow failure mode in electricity-free proportional injection that a cheaper venturi without that check valve won't catch.
The Dosatron line runs entirely off line pressure with no electrical failure point, but flow capacity spans three orders of magnitude between the D07 and D400 — on a mis-specified job the risk isn't the technology, it's undersizing or oversizing the proportioner for the flow it actually has to see.

Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
FAQ
Is Water-Powered / Proportional Chemical Injection System compatible with Water/Aqueous?
AXEON's XP-Series page carries a useful chemical-to-problem reference table that belongs on an open page: iron removal via hydrogen peroxide or chlorine (eliminates staining/metallic taste); hydrogen sulfide control via chlorine or potassium permanganate (removes rotten-egg odor); pH adjustment via soda ash or caustic soda (prevents corrosion, improves treatment efficiency); disinfection via chlorine or UV; scale prevention via polyphosphates; manganese removal via potassium permanganate (prevents black staining). Antiscalant injection is named separately. The vendor also describes a complete well-water treatment train worth publishing as a reference sequence: pressure tank integration, then retention tank for contact time, then post-carbon de-chlorination, then backwashing filters. Dosatron adds the electricity-free proportional alternative across three orders of magnitude of flow. This is strong evidence.
