Reverse Osmosis – Drinking Water Purification System

Reverse Osmosis, Water Filters and Water Purification Systems. Reverse osmosis separation technology is used to remove dissolved impurities from water through the use of a semi-permeable membrane. RO technology involves the reversal of flow through a membrane from a high salinity, or concentrated solution to the high purity

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

Choosing a home water purification system Drinking water should be based on the contaminants in water supplies and other personal needs. Drinking water systems by reverse osmosis is effective. But now, because of chemical contaminants such as herbicides and pesticides, and traces of prescription drugs, which are no longer sufficient.

Reverse Osmosis (RO) removes only the things that are heavier or larger than the water molecules. They only do that when regular maintenance. Distillers remove the only things that have a high boiling point of water. Most synthetic chemicals will not be removed through either process.

If a reverse osmosis system to purify drinking water requires electricity to operate. RO creates gallons of wastewater. Therefore, it is a good choice from the standpoint of the environment. They are also less economical alternatives.

Home Filtration of Tap Water

It’s like clockwork. Every few days a new product is launched in the market with promises of being the best way of home filtration of tap water. How does one choose a water purifier out of this huge variety of choices?

To find out which purifiers are good for home filtration of tap water, we first need to understand the nature of the water being supplied in our homes.

This water contains a lot of impurities inside. Starting from chemicals like chlorine and chloramine, heavy metals like lead and asbestos to other chemicals like pesticides and prescription drugs – all of them are commonly found in tap water.

Types of Water Purifiers

The most basic kind of water filter that you can get is one containing just a carbon filter. These purifiers are able to remove the dirt in the water and simple chemicals like chlorine too. But anything more complex like metals or pesticides are beyond these systems – something more advanced is needed for them.

Water Distillers work on the principles of distillation. Basically the water to be purified is taken in a container which is then heated to vaporize the water. The water vapors are then collected in a separate container and cooled down to get purified water – since the impurities have been left behind in the first container.

This is good enough for removing dirt and metals from the water, but any kind of contaminants which have a boiling point similar to that of water will also get vaporized and will be present in the purified water too. Chlorine for example, cannot be removed from the water by these filters because of this very reason.

Reverse Osmosis Systems purifier have become quite popular lately. These systems purify the water by forcing it to pass through a semi permeable membrane. This membrane allows water to pass through but the contaminants which have a bigger molecular size than the pores of the membrane are blocked and left behind.

This technique is all right for removing the big impurities like dirt from the water. But chemicals like chlorine and pesticides, which have very small molecules, are not filtered out by these systems. Another disadvantage is that minerals like calcium and magnesium which are necessary for our body’s proper functioning are also removed from the water by these purifiers.

The best way for home filtration of tap water, is in fact to use a cutting edge filter that can remove all these contaminants, and preserve the minerals in the water at the same time. One with the combined technologies of carbon filtration, ion exchange and sub micron filtration.

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.
