Signals tracked for Tetrasolv Filtration
The public signal classes we would read for Tetrasolv Filtration, ordered by how close each sits to a GAC vessel, rental, media, or field-service decision. A record moves to the Accounts tab only when it has a dated site-level change, a live project stage, and a reachable decision route.
How we rank a signal
PFAS detection is not a buyer window by itself. A useful record must identify the water stream, the treatment duty, the current project stage, and the person or process that controls the next decision.
We rank the commercial opening, not the size of the headline. An open GAC bid beats a large funding announcement when the funding record does not name the technology, deadline, or supplier route.
Closest to the decision
Open now to ninety daysA supplier can act against a dated process or specification window.
Open GAC equipment or operation procurement
An official bid names the treatment duty, proposal date, operating scope, and submission route.
From this screenDelaware DHSS Division of Public Health: proposals due September 15, 2026 for mobile PFAS treatment operation, maintenance, and media work.
Pre-bid vessel and media specification
A treatment project is still moving from preliminary design to the document that will control acceptable vessels, media, and equipment.
From this screenSouth Granville Water & Sewer Authority: 90% design due in September 2026 for pressure vessels and GAC or ion-exchange contactors.
Lead-vessel breakthrough or media changeout
Operating data shows that media is nearing replacement, creating a service, reactivation, or replacement-media decision.
Forced project clocks
A legal, design, or emergency deadlineThe event forces work to move, but the supplier route still needs to be tested.
Approved cleanup design moving to construction
A regulator has approved the remedy, and the owner can move into contractor, fabrication, equipment, and service planning.
From this screenBASF North Works: EPA approved the final groundwater remedy in June 2026, with construction authorized for early 2027.
Emergency temporary-water order
A regulator requires interim treatment before a permanent remedy is ready. Fit depends on flow, system scale, and whether a consultant already controls access.
Treatment technology selected before final design
A public project record chooses GAC or another train while vessel sizing, media, and equipment packaging are still being developed.
Watch until the route opens
Monitor for the next dated changeThese are real projects, but they are not yet strong enough for a confident supplier approach.
Funded PFAS treatment without a final technology
Funding proves ability to spend, but it does not prove which treatment train, equipment package, or supplier will be used.
GAC versus ion-exchange pilot
A pilot can shape media selection and full-scale design. It becomes stronger when the owner publishes the next design or procurement date.
Ion-exchange-only program
Keep it under review, but do not present it as direct fit until Tetrasolv confirms a commercially proven ion-exchange lane.
Confirming only
Never lead with these aloneDetection, regulation, company size, or general funding
These facts explain why a market exists. They do not show that a specific site is choosing equipment or changing media now.
What each account arrives with
- The site, water stream, treatment flow, and media train where the public record provides them
- The exact project stage and dated clock that create the window
- The utility owner, engineer, regulator, or procurement contact who controls the next step
- A checked work contact, a practical opening, and the sentence we must not overclaim
Accounts whose window has not opened are timed and held. They return only when a dated project change makes the route useful.
Signal classes describe categories of public record. Per-account claims and their source links live on the Accounts tab. These records do not prove purchase intent, budget, or supplier openness.
