Aggressive water chemistry destroys ordinary filtration from the inside out. Chemical resistant water filtration is a materials problem first — pick the right housing alloy and cartridge media, and everything else follows.
Housing Materials, in Order of Escalation
- 304/304L stainless — the standard for general industrial water service
- Electropolished 316/316L stainless — chlorides, brackish water, seawater and most process chemistry
- Fusion-bonded epoxy-coated steel — a cost-effective barrier option in Harmsco’s COAT housing line
Cartridge Media That Shrug Off Chemistry
Harmsco’s all-polypropylene and polyester cartridge families handle acids, bases and oxidizers across a wide pH range, while high-temperature media extend service to 250°F where hot chemistry compounds the attack. Every media family in the Harmsco cartridge catalog publishes its compatibility, so selection is engineering, not guesswork.
Where It Matters
Plating and surface finishing, chemical dosing loops, CIP return water, oilfield produced water, mining leachate and any process where pH strays from neutral — these are the services where a standard housing quietly corrodes and a chemical resistant water filtration package keeps working.
Send us your chemistry — concentrations, temperature and pH. Harmsco’s engineers will match housing alloy and cartridge media to the stream, backed by 65+ years of American manufacturing.
