Robust microfiltration membranes for the most difficult applications

Our polysulphone MF membrane with a 300K MWCO provides high flow and rejection with excellent tensile strength. These are constructed sanitary style with a polypropylene net wrap and its components conform to:

• FDA regulation CFR Title 21
• “3A Sanitary Standards for Crossflow Membrane Modules, Number 45-02”
• EC Reg No. 1935/2004
• EU Reg No. 10/2011

Applications

• Clarification application in the sugar industry
• Clarification of enzyme streams
• Processing of fruit and vegetable juices
• Clarification of wine and other liquid food products

Main Features

SanRO® and SanRO® HS elements feature a net-type outer wrapping that allow easy access for cleaning in place with specially selected components for durability in daily sanitization. These energy saving highly permeable, high rejection membranes provide high flux and low-energy costs. All elements are heat-set at the factory for predictable flows at the outset of installation.

Superior concentration of high value products

Hydranautics’ 40+ years of manufacturing best high rejecting brackish water RO membranes is incorporated into making HYDRApolish elements. HYDRApolish composite polyamide reverse osmosis elements are of net wrapped, full fit design, intended for daily CIP in the dairy environment. Hydranautics has set new industry standard by manufacturing robot-based automatic rolling machines, specially designed for fabricating membrane modules of the highest quality. The result is a high level of filtration and separations performance for our customers.

Hydranautics’ auto-rolled HYDRApolish elements provide superior glue-line adhesion and strength, tighter rolling and caging, greater flow rates due to maximized effective membrane area and great structural reliability.

HYDRApolish is designed specifically for dairy process applications requiring continuous operation at high pressure, high temperature, or periodic heat sanitization at high temperature.

HYDRApolish applications

• RO permeate polishing
• Condensate polishing
• Pre-concentration of milk or whey for reducing product transport costs
• Lactose Production
• Juice concentration

Excellent concentration and de-mineralization

Hydranautics’ membrane technology experience and innovation are at the core of every DairyNF series membrane. Specifically designed for the separation of divalent anions and/or organic molecules greater than 200 Daltons from monovalent salts and lower molecular weight organics, DairyNF membranes deliver exceptional performance and value.

Superior membrane technology is the key to Hydranautics’ innovative DairyNF (Process Nanofiltration) elements.

All DairyNF membranes are manufactured using highly controlled, ISO 9001-compliant processes, ensuring the highest quality and most consistent, reliable performance available. Hydranautics has set a new industry-standard for the rolling of full-fit membrane modules: Hand-rolling of elements has been eliminated by the use of proprietary, robot-based automatic rolling machines, specifically designed by Hydranautics for fabricating membrane modules of the highest quality. The result is a higher level of filtration and separations performance for our customers.
