PRE RO
Why considering VORTISAND® filters for RO pretreatment?
VORTISAND® will protect RO membranes efficiently
VORTISAND® requires less backwash water than any conventional filters
Considerable bag filters and maintenance savings
Small footprint units for space saving
Ultra fine particle removal down to 0.45 micron.
VORTISAND® filter is the best solution for an efficient Membrane protection.

RO membrane systems usually require a turbidity of <1 NTU and SDI < 5. This means that the objective of the prefiltration should be to reduce the TSS to a level that would be < 0.5 ppm or better. There are very few options to consider here for the prefiltration of the raw water.

VORTISAND® provides a filtration that is 10 to 20 times finer than the traditional sand filters. Its high performance results from a unique concept that combines centrifugal separation and sand filtration and this is what makes our filter the best available polishing solution to RO.

Pre ro filtration
VORTISAND® used as RO pretreatment for membrane protection.
Small footprint of the VORTISAND allowed easy installation in existing plant.
VORTISAND used for major Municipal Wastewater Reuse Application in Texas.
Great particle removal efficiency acheived in one-pass through the filter.

APPLICATION BRIEFS:

What our customers say:
"At our pharmaceutical plant, we have placed the VORTISAND for one year now we just opened the 5 micron filter housing (where we never developed an increased pressure drop in 6 months use) and this is what the filters looked like no visible dirt only discoloration from the effects of Peracetic acid used once per month for sanitization. The VORTISAND is doing very very well.Thank you"
