Ozone water treatment solutions – ozone generators and ozonators from Pure Aqua

Pure Aqua, Inc. 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.

Ozonation

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

Ozone Water Treatment Systems

Ozonation has recently gained popularity as a treatment alternative in the United States after regulatory agencies placed restrictions on the disinfection by-products, especially levels of tri-halomethane (THM).

Ozonation is an established and proven disinfection alternative as well as a peroxidant for the control of THM precursors. It also has the benefits of:

  • Oxidation and volatilization of organics
  • Control of algae and associated compounds
  • Destabilization (microflocculation) of certain types of turbidity
  • Removal of color-causing compounds
  • Oxidation of iron and manganese
  • Very short disinfection times
  • Partial oxidation of organics for subsequent removal by microorganisms.

Ozone Generator Selection

Ozone is generated by passing a high voltage alternating current (6-20 kV) across a dielectric discharge gap through which oxygen gas is injected. Setting aside the sales pitches from manufacturers, most practical generators are either low (50-60 Hz) or medium (200-1000 Hz) frequency. Medium frequency generators are generally considered better performers. It is often helpful to contact Pure Aqua in similar applications to finalize the selection of an ozone generator.

Water Softeners and Water Softener Systems

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 Pure Aqua 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.

What do water softeners do?

Industrial water softeners are specific ion exchangers that are designed to remove ions, which are positively charged.
Softeners mainly remove calcium (Ca2+) and magnesium (Mg2+) ions. Calcium and magnesium are often referred to as ‘hardness minerals’.
Softeners are sometimes even applied to remove iron. The softening devices are able to remove up to five milligrams per liter (5 mg/L) of dissolved iron.
Softeners can operate automatic, semi-automatic, or manual. Each type is rated on the amount of hardness it can remove before regeneration is necessary.

Commercial water softeners collect hardness minerals within its conditioning tank and from time to time flushes them away to drain.
Ion exchangers are often used for water softening. When an ion exchanger is applied for water softening, it will replace the calcium and magnesium ions in the water with other ions, for instance sodium or potassium. The exchanger ions are added to the ion exchanger reservoir as sodium and potassium salts (NaCl and KCl).

How long does a water softener last?

A good water softener system will last many years. Water softeners that were supplied in the 1980’s may still work, and many need little maintenance, besides filling them with salt occasionally.

Softening salts

For water softening, three types of salt are generally sold:
– Rock salt
– Solar salt
– Evaporated salt

How often should one add salt to a softener?

Salt is usually added to the reservoir during regeneration of the softener. The more often a softener is regenerated, the more often salt needs to be added.

Usually water softeners are checked twice a month. To guarantee a satisfactory production of soft water, the salt level should be kept at least half-full at all times.

With expertise of Pure Aqua’s water softener systems you will receive economical solution that creates value for you while reducing your costs. to know about Reverse Osmosis Systems and also read more about Water Purification Systems

Water Filters and Water Filtration Systems

MULTI-MEDIA WATER FILTERS (Depth Filters)

Multi-media water filter system represents a significant improvement over single-media filters. This is primarily due primarily to improved filter bed action based on the innovative use and selection of filter media. Multi-media filtration permits delivery of high quality filtered water at much faster flow rates, as compared to a conventional sand filter.

In a conventional sand filter, lighter and finer sand particles are found at the top of the filter bed, and coarser, heavier sand particles remain at the bottom after backwashing. Filtration takes place in the top few inches of the filter bed.

A multi-media filter is backwashed in the same manner as a sand filter, using reverse or upward flow of water through the filter bed. The various layers of media retain their stratification because each material has a different density.

Advantages

1. The multi-media water filter systems operate for much longer periods of time (five or more times as long at the same filtration rate), before backwashing is necessary because the bed can hold more turbidity. Turbidity is trapped and held throughout the entire bed depth, rather than the top one or two inches.

2. Multi-media filtration is much better suited for use in a closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is virtually eliminated and the need for visual inspection is unnecessary.

The use of pressure tanks, rather than open basins or filters, is an obvious advantage for point-of-use filtration and could also be of real importance in the filtration of small community water supplies.

More rapid filtration flow rates in multi-media filtration allow the use of smaller diameter tanks with equal or better results.

3. A very high degree of clarity is achieved in the filtered water because of the fact that the finer particles of garnet at the bottom trap finer turbidity particles.

4. Another important advantage is that multi-media water filters can clarify water at a much higher flow rate than a single-media sand filter (5.5 to 8 gallons per minute, as compared to 1.5 to 2.5 gallons per minute in a 12 inch diameter tank). This is 14 to 15 gpm per square foot of bed area, as compared to 2 gpm per square foot of bed area. This is a very important difference in the production of filtered water.

Pure Aqua’s multi media water filters (MF-1100, MF-1000, MF-600, MF-500 MF-450, MF-410 MF-400 Series) clarify water by removing sediment, turbidity, iron, unpleasant tastes and odors, suspended particles, and unwanted color, all of which are commonly found in surface water. They can be used in a variety of service conditions including, but not limited to: industrial, municipal, and institutional applications.

Pure Aqua multi media water filter systems are ideally suited for use where stringent water quality standards are required or where higher levels of suspended solids are present. These applications can include re-use applications, water pre-treatment applications for reverse osmosis and deionization systems or as a pre-treatment system prior to disposable bag or cartridge filters. Pure Aqua multi-media water filter systems are also widely used as primary water filters for removal of suspended solids in incoming plant water or in waste water clean up applications.

Reverse Osmosis Chemicals

Reverse osmosis chemicals to improve the performance of your reverse osmosis system’s membranes.

Reverse osmosis (RO) membrane performance can be negatively impacted by impurities that build up on the membrane surface during operations. Suspended solids, microorganisms and mineral scale can foul membrane elements. These deposits can cause loss in output and/or rejection levels and reduce total system performance.

The membrane separation process utilizes a high-pressure feed to force water through a semi-permeable barrier. As the water passes through the membrane, contaminates are rejected and eventually flushed to the waste stream. The concentration of the contaminants is crucial to determine the design and operation of the membrane system. During normal operations, membranes can become fouled by colloidal material, inorganic oxides, biological matter, and scaling salts.

Fouling involves the entrapment of material in the feed water or deposits on the membrane surface. These deposits can accrue until they cause a reduction in flow, increase in feed pressure requirements, loss of salt rejection, or all three.

Pure Aqua membrane chemical’s products are formulated to treat a wide variety of commercial reverse osmosis (RO) systems, nanofiltration (NF), and ultrafiltration (UF) systems.

Pure Aqua offers a wide array of products to help you improve the performance of your membranes:

Antiscalants:

The Antiscalant chemical from Pure Aqua is designed to eliminate scale and reduce fouling in membrane systems, regardless of the feedwater source.
