Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron.  Typically, ultrafiltration will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules.  Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed.  Because only high-molecular weight species are removed, the osmotic pressure differential across the membrane surface is negligible.  Low applied pressures are therefore sufficient to achieve high flux rates from an ultrafiltration membrane.  Flux of a membrane is defined as the amount of permeate produced per unit area of membrane surface per unit time.  Generally flux is expressed as gallons per square foot per day (GFD) or as cubic meters per square meters per day.
Ultrafiltration membranes can have extremely high fluxes but in most practical applications the flux varies between 50 and 200 GFD at an operating pressure of about 50 psig in contrast, reverse osmosis membranes only produce between 10 to 30 GFD at 200 to 400 psig.

Reverse osmosis (RO), also known as hyper filtration, is used by our Commercial & Industrial Brackish Water & Seawater Reverse Osmosis Systems to purify water by removing salts and other impurities. It is also capable of rejecting bacteria, sugars, proteins, particles, dyes, and other constituents that have a molecular weight of greater than 150-250 daltons.

SAI-TREAT manufactures a full line of seawater desalination systems designed for heavy or continuous duty service in the marine applications where quality and dependable performance are keys. Our standard Brackish Water Reverse Osmosis systems are available with capacities ranging from 250 GPD to 500,000 GPD, and our standard Seawater Reverse Osmosis systems or water makers or RO desalination systems are available with capacities ranging from 200 lit/hr to 20000 lit.hr. SAI-TREAT is also capable of manufacturing custom built Reverse Osmosis plants.

Municipalities and industrial facilities are able to use RO permeate as a consistently pure drinking water supply and to transform drinking water to high purity water for industrial use at microelectronics, food and beverage, power, marine and pharmaceutical facilities.

Water Softeners

A water softener system is a unit that is used to soften water, by removing the minerals that cause the water to be hard.

Water softening is an important process, because the hardness of water in different applications is reduced during this process. 
When water is hard, it can clog pipes, damage boilers, heat exchangers, and many other devices. Water softening can prevent these negative effects. 
Hard water causes a higher risk of lime scale deposits in industrial, commercial and household water systems. Due to this lime scale build-up, pipes are blocked and the efficiency of hot boilers and tanks is reduced. This increases the cost of domestic water heating by about fifteen to twenty percent. 
Another negative effect of lime scale is that it has damaging effects on household machinery, such as laundry machines. 
Water softening using SAI TREAT water softener system expands the life span of each household machine, such as laundry machines, and the life span of pipelines. It also contributes to the improved working, and longer lifespan of solar heating systems, air conditioning units and many other water-based applications.

SAI TREAT is a leading provider of deionization solutions. Our water deionizers are rugged, pre-engineered, pre-assembled, standardized units that minimize expensive installation and start-up costs. We have designed our Deionization systems to maximize the efficiency and repeatability of the unit during the service and regeneration modes

The Process of Deionization or Ion-exchange

In the context of water purification, ion-exchange is a rapid and reversible process in which impurity ions present in the water are replaced by ions released by an ion-exchange resin. The impurity ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form. (An ion is an atom or group of atoms with an electric charge. Positively-charged ions are called cations and are usually metals; negatively-charged ions are called anions and are usually non-metals).

Application specific design 

SAI-TREAT designs and assemble complete ozone generators and ozone water treatment systems for commercial, residential and industrial water treatment purposes. Applications range from treating swimming pool water to food processing water and bottling applications.
Ozone is a strong oxidizer and can be particularly effective for water and waste water treatment with less than 1% organic content. It is sometimes used as a pretreatment method, or to disinfect wastewater after biological treatment. It oxidizes a wide range of organics, can destroy cyanide wastes and phenolic compounds, and is faster acting than alkaline chlorination. And, unlike chlorine, ozone doesn't generate toxic ions in the oxidation process.

Ozone is the triatomic form of oxygen formed naturally during lightning strikes and anytime an electric arc is formed. It is a very unstable compound and must be produced at the same time it is needed, usually by ultraviolet excitation and corona discharge. It isn't effective in treating slurries, sludges, solids, organic solvents, or tars.

Before use, consider the possibility that ozone will oxidize other stream components that didn't need treatment. Excess ozone, (that is, ozone not consumed in the reaction) must be catalytically decomposed since release isn't permitted

SAI-TREAT manufactures a full line of seawater desalinators designed for heavy or continuous duty service in the marine applications where quality and dependable performance are key. Our Water Desalination Reverse Osmosis series is available with capacities ranging from 200 lit/hr to 20,000lit/hr for commercial needs and for industrial use.

ELECTROPURE  EXL-600 modules are specifically Designed as direct replacement for E-cell MK-2 and MK-2E modules and lonpure@ LX-24 and LX-30 modules. They are configured to easily retrofit existing Systems with added electropure technology benfits, so the old troublesome E-cell CONCENTRATE RECIRULATION IS ELIMMANATED.
The new ELECTROPURE EXL-600 Modules have the same physical profiles as E-cell MK abd IONPURE lX modules but have Electropure EDI technology inside. This includes Electropure’s  Patented Excellion Membranes, New “ never-leak” permanent O-ring Seals, Our unique Non-scaling electrode system, our efficient thin cell technology, and Our GF union connectors.  
With Electropure EDI thin Concentrate technology, There is no there is no need for the troublesome E-coli or Emexell recirculation system, so it can be estimated from the system. With the mass-transfer built into electropure EDI thin-concentrate technology, you don’t need either salt injector of feed-and-bleed systems. You also don’t need the IONPURE “all-filled” design.
