Pre-treatment for Reverse Osmosis

Why use Pre-treatment Equipment?

RO is designed to filter out dissolved solids not suspended solids. Colloidal materials, bacteria and suspended solids will block the feed channels of an RO membrane and cause fouling. Pre-treating with equipment and chemicals will increase the life of membranes. In the long run, pretreatment will save money and ensure RO reliability.

What Is Your Water Temperature?

Higher Temperature is designed for lower pressure and a smaller pump because warm water has lower viscosity. Lower temperature is designed for higher pressure is good for a larger pump since cold water has a higher viscosity.

Does your water temperature vary 10 celsius or more?

Make sure to adjust pressure to maintain consistent permeate Flow. Variable Frequency Drive (VFD) is highly recommended.

Do you have multiple wells? Does your water quality change?

Need water analysis of all sources whenever possible. When seasonal changes occur we need wet/dry season samples.
