Membranes are the Key to Superior Effluent Quality
• Hollow, porous plastic fibers with billions of microscopic pores on the surface
• The pores are thousands of times smaller in diameter than a human hair
• Pores form a physical barrier to suspended solids and colloidal particulates larger than the membrane pore size

Membranes Offer More Protection than Dual-media Filtration
UF Pre-treatment for RO
ZeeWeed & RO – The Ideal Partnership
Ensure RO reliabilitySuperior RO system protectionSilt density index (SDI) < 2Process simplificationHigher RO flux ratesExperience – > 90 UF/RO plants
Reduced capital and operating costs
Minimal downtime means virtually no production or process interruptions
$ The biggest bang for your buck $
Why Pretreatment ?
Ensure RO Reliability Remove colloidal matters, bacteria and inorganic suspended solids which will block the feed channels causing pressure dropRemove sparingly soluble salts, minimizing scalingTo minimize fouling due to bacteria growth
Reliable Pretreatment is Critical
> High rate of membrane fouling> High frequency of membrane cleaning> Lower recovery rates> High operating pressure> Poor product quality> Reduced membrane life> Reduced plant productivity
RO membranes are sensitive and require a continuous supply of high quality feed water.
Ineffective pretreatment can result in RO system problems, including:
Bacteria, mineral salts and shell fragments on SDI filter paper
Typical RO Feed Water Limits
SDI < 5 (ideally < 3 or better) TSS < 1 mg/lTurbidity < 1 NTUTOC < 5 mg/LLSI < 2.0 (with sequestrant)Fe < 0.05 mg/l, Mn < 0.05 mg/l
