Common Water & Wastewater Treatment Chemicals in Polypropylene

Each chemical page shows the rating for polypropylene tanks, fittings and EPDM, Viton and Buna-N gaskets.

What to consider

Getting the Right Tank the First Time

Send the chemical, concentration, temperature and size. We’ll match the resin, specific gravity rating and fittings.

  • Double wall where it counts: a tank inside a tank gives secondary containment for sodium hydroxide, acids and ferric chloride without a separate dike.
  • Cold-weather caustic: 50% sodium hydroxide starts to crystallize as it cools, so insulated tanks with heat tracing are common for outdoor caustic storage.
  • Fittings rated for the chemical: polypropylene fittings with EPDM, Viton or Buna-N gaskets chosen from each chemical’s compatibility page.
  • Ready for your piping: fill, vent, overflow, outlet and level connections installed at our Willis, Texas plant.
