Duo-Pro is Asahi's own recommended system for DLE brine/acid handling per the ASAHI FOR DLE source; named chemistries are sodium hypochlorite, chlorine dioxide and acids (lithium-rich brine eluents). The 30-day EPA containment figure is the quotable design basis on a DLE permitting conversation.

Real Specifications
| Duo-Pro size/pressure range | 1x3 through 16x20, 150 psi + drainage ratings | asahi-america.md |
| Outer pipe containment standard | Designed to meet the EPA standard of at least 30 days of containment | asahi-america.md |
| Leak detection cable install threshold | PAL-AT cable-based leak detection installable on 2x6 and larger | asahi-america.md |
| Recommended DLE valve/actuator pairing | Type-14 Diaphragm Valve + Series 19 MAV MultiPack electric actuator, 75% duty cycle, NEMA 4X enclosure | asahi-america.md |
| Duo-Pro materials | PP, PVDF, or ECTFE | asahi-america.md |
Type-14's top-entry design isolates the bonnet from the fluid, so only the body and diaphragm (available in PVDF/PTFE/EPDM) ever touch the brine — the failure mode it's built to avoid is abrasive-slurry or corrosive-brine intrusion into the actuator side of the valve.
A DLE brine line runs acid and abrasive slurry continuously for the life of the plant — Duo-Pro's 30-day EPA containment design basis on the outer pipe is a real, vendor-published number worth quoting in a permitting conversation, not a rounded-up estimate.
