DESALATION SYSTEMS
Aqva Safe Vision desalination systems feature Reverse Osmosis (R/O) technology. Aqua  safe vision designs are state-of-the-art, optimizing efficiency, reliability, product water quality, and overall low cost per unit of water. Pure Aqua advanced designs recover higher percentages of the feed water as good quality product water. Boiler feed quality may be obtained by using specialized Pure Aqua equipment designed for that purpose, even from seawater feed containing up to 50,000 PPM TDS. Pure Aqua, Inc. has extensive experience desalting seawater all around the world. Let us put that experience to work for your benefit!

BRAKISH WATER
Reverse osmosis, also known as hyper filtration, is used by Brackish Water Reverse Osmosis Systems to purify water and remove 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 Dalton.)

  • MEMBRANE CLEANING
    The cleaning skid is designed for manual operation through a local control box located on the skid. A chemical storage tank is mounted on its own stand and connected to the skid with either hard PVC piping or quick disconnect fittings and flexible hoses. This gives the unit the ability to be mounted in a permanent location or totally portable if desired. The piping is schedule 80 PVC that is hydrostatically tested at the factory. The electrical enclosure is NEMA 4X. All skid wiring is completed and tested before shipment.

DEGASIFIERS

Aqva Safe Vision Forced Draft Degasifiers are used to remove unwanted gases from supply water. The degasifier removes the gases by passing the water over a packing media that helps the water form a thin film over the surface area of the tower. A counter current airflow is introduced at the bottom of the tower and travels up the stack through the descending flow of water. The gases are stripped as the air passes over the surface area of the water.
Degasifiers are used in demineralizer applications to strip CO2 following a strong acid cation exchanger or softening application. They can also be used as an economical way to strip hydrogen sulfide or volatile organic compounds (VOC).
Aqva Safe Vision  Industrial has a complete line of Forced Draft Degasifiers available. The systems start at 75 gpm and go up to 1000 gpm.

  • MEMBRANCE BIORACTOR  (The Membrane BioReactor (MBR) is a state of the art pre-engineered sewage treatment system utilizing Aqva Safe Vision ’s water treatment expertise with Toray’s submerged membrane technology. The membrane separateion process eliminates the conventional sedimentation tank and allows high volumetric loading, resulting in a smaller footprint. The MBR can produce high quality effluent with high BOD5 removal (about 98%), complete nitrification and partial de-nitrification and achieves virtually complete TSS removal.

UV Sterilizers

Aqva Safe Vision uv sterilizers   utilize germicidal ultraviolet lamps that produce short wave radiation lethal to bacteria, viruses and other microorganisms present in water.

Ultraviolet water treatment purification is a unique and rapid method of water disinfection without the use of heat or chemicals.

Through the years ultraviolet technology has become well established as a method of choice for effective and economical water disinfection.

Aqva Safe Vision Ultraviolet Water Treatment Purifiers are the ideal solution for an ever growing range of water treatment applications. We provide UV water treatment systems from well known brands like Sterilite and R-Can.

Effective

Virtually all microorganisms are susceptible to Pure Aqua ultraviolet disinfection.

Economical

Hundreds of gallons are purified for each penny of operating cost.

Safe

No danger of overdosing, no addition of chemicals.

Fast

Water is ready for use as soon as it leaves the purifier – no further contact time required.

Easy

Simple installation and maintenance. Compact units require minimum space.

Automatic

DEIONIZERS (Deionizers

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).

The following ions are widely found in raw waters:

Cations Anions
Calcium (Ca2+) Chloride (Cl-)
Magnesium (Mg2+) Bicarbonate (HCO3-)
Sodium (Na+) Nitrate (NO3-)
Potassium (K+) Carbonate (CO32-)
Iron (Fe2+) Sulfate (SO42-)

)

RO PRETREAMENT (Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective,” this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules. This is the reverse of the normal osmosis process, in which the solvent naturally moves from an area of low solute concentration, through a membrane, to an area of high solute concentration. The movement of a pure solvent to equalize solute concentrations on each side of a membrane generates a pressure and this is the “osmotic pressure.” Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis.

The process is similar to membrane filtration. However, there are key differences between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect exclusion of particles regardless of operational parameters such as influent pressure and concentration. Reverse osmosis, however involves a diffusive mechanism so that separation efficiency is dependent on solute concentration, pressure and water flux rate.
