RO Desalination Plants
These pre-engineered packaged desalination plants are available in base sizes of up to 2 million gal/d, and modular building blocks can be added to expand plant capacity to as high as 50 million gal/d. This reverse osmosis (RO) seawater processing system combines a lightweight, large-diameter pressure vessel with the manufacturer’s MegaMagnum PLUS seawater technology. One MegaMagnum element measuring 18 in. dia. by 61 in. long provides an economic alternative to the traditional configuration that requires seven standard 8-in. by 40-in. elements. High-rejection MegaMagnum elements are available for high flow and typical flow seawater applications.

SelRO nanofiltration membranes
SelRO nanofiltration membranes provide chemical and thermal stability to satisfy requirements of processes involving high or low pH, high temperature, or organic solvent media. Other nanofiltration membranes are limited to aqueous applications within a pH range of 2 to 11. These restrictions are insufficient for pharmaceutical and other fine-chemical applications where aggressive cleaning measures are necessary. SelRO membranes are stable in both acids and bases, and can be operated over the full pH range of 0–14.

Fluid Systems TFC-SR spiral-wound elements
Fluid Systems TFC-SR spiral-wound elements are a cost-effective solution for dairy and other food processing applications where the feedstream is of low solids density and minimal floor space is available. Designed to USDA 3-A standards and FDA regulations, these elements handle a variety of selective rejection applications, including deashing and separation of carbohydrates and proteins. They can also be used for whey preconcentration, salt whey diafiltration and lactose demineralization. For cleaning-in-place, the allowable pH range is 2.5 -9.0 for SR2 elements and 1.0–11.0 for the SR3 and SR4 elements. The membranes are available in 40-inch long elements, 4 in. or 8-in. in diameter.

TFC SR2 Spiral-nanofiltration (NF) Element Fluid System
The Fluid Systems TFC SR2 spiral-nanofiltration (NF) element significantly lowers operating costs for a wide variety of selective rejection applications, including water softening, lactose reduction, protein recovery, and antibiotic and enzyme concentration and recovery. The SR2 membrane is highly energy efficient and capable of producing more water per square meter of membrane surface area than competitive products. Hardness rejection is typically 95% and organic rejection exceeds 90% for organics with molecular weights in the range of 400–600 daltons. The SR2 element softens incoming water and retains low-molecular-weight organics, while allowing monovalent salts to pass through the membrane. The membrane concentrates pharmaceuticals without phase change in aqueous mother liquors. In water treatment applications, the SR2 element softens without the need for disposing of regeneration solutions and it eliminates contaminants without the need to process large volumes of sludge or wasted regenerants.
