Osmonics Desal membranes

Osmonics Desal membrane elements are divided in the following catagories: AD AD membrane elements are characterized by a very good sodium chloride rejection. AD Seawater Elements feature high-pressure construction. AD2540FM AD8040F AD4040FM HR AD8040F HR AD4040FM AD8040F-400 HR

AG

AG Standard Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psi are desired. These elements allow moderate energy savings, and are considered a standard in the industry.

AK

AK elements are selected when high rejection and low operating pressures are desired. These elements allow significant energy savings since good rejection is achieved at low operating pressures.

AG

AG Standard Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psi are desired. These elements allow moderate energy savings, and are considered a standard in the industry.

CD

The C series elements have a higher rejection and better chemical stability than standard cellulose acetate and they offer a lower cost per element and increased chlorine resistance compared to thin-film elements.

Duraslick

Duraslick is a family series of membrane elements engineered for use with fouling-prone brackish water applications. Duraslick is designed to utilize an innovative three-layer membrane, of which a proprietary middle layer creates extreme smoothness, and provide a high rejection of salts.

Duraslick HS

Duraslick HS elements are specially designed for comparatively higher suspended solids levels.

Duratherm HWS

The Duratherm RO HF Series is specifically designed to maximize the benefits of continuous high temperature operation as well as hot water sanitization for industries willing to maximize energy recovery and use hot purified water. Separation system sanitization protocol is performed via periodic exposure to temperature as high as 90°C at minimum feed pressure to kill microorganisms by denaturation and coagulation of the proteins chains.

The Duratherm HWS RO and HWS NF are suitable for separation systems purifying water at temperature up to 122°F (50°C), Duratherm HWS UF up to 158°F (70°C) in low crossflow environment and no suspended solids.

Seasoft Series

NF has the unique ability to selectively reject ions:

• Rejection of anions with more than one negative charge

• Rejection of cations depending on shape and size

• Rejection of organic if molecular weight is >200-300 Daltons

• At least 80% of water hardness is removed with low operating pressure and high flux.

EW Series

The EW family of elements should be selected when pretreatment is in need to keep a reverse osmosis or a nanofiltration system running. EW will remove suspended solids and other known foulants.

HL Series

HL Nanofiltration Elements are used for water softening, color removal, and reduction of THM formation potential.

PW Series

PW Elements are used for pretreatment of process water and post treatment of ultrapure water.
