Turbidity has no direct correlation to required micron rating for pre-filters.
- i.e. your typical cotton wound or poly spun pre-filter will catch sediment and other solids, will also partially help with other particulate matter, but depending on the current FWA you will apply the correct pre-treatment (i.e. flocculent or chlorine injection) and upstream vessel filtration (3-5 vessel in service with 1 in staged B/W).
Depending on your application your design requirements will change.
Small on demand WTP often wrongly depend on staged filter cartridges before RO (i.e. 50mic followed by 10mic or 5mic).
A better setup will cost more, but saves money, increases output and reliability...
===> For Potable WTP Pre-injection, Contact Tank to Feed Tank, MMF, CMF, Interim Injection if required, Contact Tank (RO Feed Tank), SMBS if required, Anti-Scalant, DGD, Polisher Cartridges, RO, Calcite Filter and post chlorination... proven best and most adaptable to design changes.

Thanks for the insights.
