Problem-first
By Challenge / Contaminant
Start from the contaminant: PFAS, heavy metals, COD/BOD, pathogens, scaling, and more.
Challenge pages group providers by the specific contaminant or problem they solve. Start here when the brief is 'remove X' rather than 'build Y'.

What you'll find here
Sometimes the problem comes first. Start from the contaminant, not the plant.
You don't always need 'a membrane plant'. You need arsenic below the limit, PFAS destroyed, or a cooling tower that stops scaling. These pages connect you with providers whose core expertise is a specific contaminant or failure mode: PFAS, heavy metals, COD/BOD, oil & grease, arsenic, trace pharmaceuticals, scale, corrosion, nitrate, ammonia, color, microplastics, silica, phosphate, biofouling, odor, and more.
