Water treatment in Tenselo
A short introduction to what Tenselo covers in this category.
DuPont FilmTec BW30-400
8″ spiral-wound brackish · Codeline 80S vessels
These figures come from the Tenselo engine. Every result Tenselo produces shows the inputs it used and the method behind it, so the work can be checked rather than taken on trust.
Why it matters on the job
Membrane array done right
Element count, vessels and flux matched to the feed water and recovery — named to real product.
Quality you can guarantee
Rejection, CT disinfection and LSI scaling all checked against the target.
Dosing that lands
Coagulant, antiscalant and disinfectant rates sized to flow and chemistry.
