Sterlitech is launching new flat sheet membranes from TriSep: SBUF and SBNF membranes. SBUF and SBNF are particularly suited for treating surface waters and for the removal of organics and color.

¹ GFD: Gallons per Square Feet Membrane Active Area per Day These new additions are available in large sheets, as well as in precut coupons for use in the Sepa CF filtration cell, CF042 filtration cell, and most stirred cells. Custom membrane sizes are also available upon request. For more information about SBUF and SBNF or if you need assistance to find products suited for a specific application, please contact Sterlitech.

Sterlitech is launching new flat sheet membranes from Dow: BW30XFR. This is a Brackish Water Reverse Osmosis Membrane particularly suited for water treatment and desalination. The BW30XFR replaces the obsolete BW30FR; however, limited quantities of BW30FR are available at the moment, please contact Sterlitech for more information or if you need assistance finding a suitable replacement product.

¹ GFD: Gallons per Square Feet Membrane Active Area per Day ² 99.65% NaCl rejection at 2,000 ppm NaCl feed, 225 psig feed pressure, 77°F (25°C). These new additions are available in large sheets, as well as in precut coupons for use in the Sepa CF filtration cell, CF042 filtration cell, and most stirred cells. Custom membrane sizes are also available upon request.

Sterlitech is launching new flat sheet membranes from TriSep: UF5 and UF10 ultrafiltration membranes. UF5 and UF10 are particularly suited for food and dairy process applications, and applications involving protein concentration.

¹ GFD: Gallons per Square Feet Membrane Active Area per Day These new additions are available in large sheets, as well as in precut coupons for use in the Sepa CF filtration cell, CF042 filtration cell, and most stirred cells. Custom membrane sizes are also available upon request. For more information about UF5 and UF10 or if you need assistance to find products suited for a specific application, please contact Sterlitech.

The TriSep UE10 flat sheet membrane is being discontinued by the manufacturer and replaced by TriSep UF10 membrane.

¹ GFD: Gallons per Square Feet Membrane Active Area per Day Discontinued products will include the following Sterlitech Part numbers:

• YMUE101905
• YMUE10475

Limited quantities of UE10 are available at the moment, please contact Sterlitech for more information or if you need assistance finding a suitable replacement product. You can browse other UF membranes that Sterlitech offers at the moment here.

This document gives general guidelines for cleaning Nanostone RO or NF elements in the ST, ST+, ST++ and DT-Module-Configuration. During normal operation the membrane elements can become fouled by constituents in the feed water. The most common foulants include mineral scale, biological, organic, colloidal particles, and metal oxides. The nature of the fouling is dependent on the system design and feed water. Proactive cleaning is necessary to reduce the potential for irreversible fouling. If the membranes are heavily fouled, the cleaning effectiveness may be reduced and the performance may be permanently impacted. At a minimum, RO/NF elements should be cleaned when:

• Normalized permeate flow drops 10-15%
• Normalized permeate quality decreases by 10-15%
• Normalized pressure drop increases 10-15%.

Notes:

• Ensure that the all water used in the cleaning process is chlorine free
• Ensure the direction of the flow during cleaning is the same as during normal operation
• Consult with Nanostone prior

Our specialty site, the Glass Fiber Store, is now closed.  When it went live in 2011, it was the place to find best selection of glass fiber filters from Sterlitech and Advantec. The products in the Glass Fiber Store have been integrated into our main site. If you’re looking for something that used to be there, try the following links:

• Glass Fiber Filters
• Extraction Thimbles
• Cellulose Filter Papers

First announced this past spring, the Botanical Extraction section of our website is now up and running! This section houses everything you need to make a complete, basic vacuum filtration system for herbal/botanical extracts including vacuum filter holders, membrane filters, trap bottles or flasks, and vacuum pumps. You can also find optional accessories, such as manifolds, that can be used to modify the filtration process to best suit the project requirements and throughput volume. If you have a need to perform any of the following applications:

• Cold-filtration to remove lipids or waxes, often called winterizing
• Clarification or plant debris removal
• Bacterial removal (using 0.2 or 0.45 micron PES filters)
• Batch processing with manifolds
• Ethanol washing

Then head to our Specialty Applications Section to find the best equipment to work with your botanical extraction process.
