8 Common Applications of a Water Treatment Plant

A water treatment plant is an amenity where waste and contaminated water is treated for making it reusable. Different techniques are used by different water plants to purify polluted water, such as filtration, sedimentation, disinfection, and chlorination. Moreover, some typical water purification equipment used in such plants include screening equipment, oil water separators, water filters, sludge treatment equipment, ozone generator, etc.

Let us now see various applications of such a treatment plant.

1. Wastewater Treatment

Treating wastewater collected from the industrial, commercial and household structures is the most usual application of a water treatment plant. The physical, chemical, biological and radioactive pollutants are removed that are present in the wastewater. Two commonly used treatment processes followed here are sludge treatment and sewage treatment.

2. Surface treatment

This process may be followed by a plant to cleanse surface water for municipal usage. In this process, the colloidal matters, organic components and suspended impurities present in the surface water are usually removed using treatment processes like screening, aeration, sedimentation, sand filtration and disinfection.

3. Containerized plants

Usually, such plants are useful for the remote areas of a country where getting pollutant-free water may seem like a luxury. However, they may also be established near mining or military camps. A single unit arrangement may be used in this type of water treatment plants.

4. Ozone-based plants

Ozone is used for the purpose of water purification in ozone-based water plants. These plants are considered to be useful for treating pool water. Ozone is an effective disinfectant for different microorganisms, such as protozoan and cryptosporidium parasites. This type of plants does not require any usage of chemical to clean polluted water.

5. Seawater treatment plants

These plants help treat seawater that contains salt and minerals. A few water treatment techniques followed by these plants are membrane separation, desalination and vacuum freezing. The USA has the highest number of seawater treatment plants in the world.

6. Package wastewater plants

The aeration process is usually used in a package wastewater plant. These plants are commonly seen in construction sites, educational sites, recreational sites and mining areas.

7. Mobile water treatment

This is a popular treatment facility offered by some water treatment companies where the reverse osmosis process is often followed. This is usually used in small scale in both rural and urban areas.

8. Bottled treatment

In this treatment, the water is collected from a certain source, sometimes even from deep under the sea; and then it is purified with high-end technology and machinery, and bottled to supply to the marketplace. The usage of bottled drinking water is rising day by day and so the number of bottled water treatment plants is also increasing in every corner of the world.

Finally, since pure water has become scarce in many parts of the world these days, the above-mentioned applications of water treatment plants are playing a vital role in saving people, animals and the environment as a whole.

Is Reverse Osmosis The Best Water Filter For Your Home?

Commonly referred to as “RO” is a very powerful technology, it is not the best water filter for most homes or offices. Reverse osmosis is best suited to address the two issues for which it was originally designed:

Desalination of seawater or brackish water and / or

Reduction of very specific chemical contaminants.

Osmosis – is one of membrane separation methods solutions and suspensions into components based on passing through the semipermeable membrane of the volume of solvent molecules with a lower concentration of solutes.

In reverse osmosis, the water under pressure passes through the membrane from a more concentrated solution in a less concentrated, i.e. during the reverse osmosis liquid cleaned of solutes.

That is, the membrane is permeable only for particles whose size is equal to or smaller than the diameter of water molecules (i.e., oxygen, chlorine and other impurities permeable membrane).

Most reverse osmosis systems require a constant flow of water to clean and flush their membranes. This water is removed as waste water. Between 50-80% of the water entering the water treatment system can be disposed of as wastewater, something called concentrate (because the contaminants are concentrated in this stream of water).

The amount of water produced by the drinking system is called the recovery rate (the amount of good quality water recovered from the original water source).

So what is the best water filter for your home or office?

RO water purifiers are decent choice for house and office use, definitely not the best one.One of the best examples of this technology which offers:

· Easy installation,

· Faucet dedicated, (retrieve your refrigerator!)

· Minimum maintenance

· Visual indicator for filter change and

· Reduce harmful contaminants to the allowable limits of ANSI / NSF, without eliminating healthy minerals.

Advantages and disadvantages

Filters based on reverse osmosis water is removed from the chlorine ions, iron, heavy metals, insecticides, fertilizers, arsenic, etc, but also magnesium, potassium, calcium and other vital micro- and macronutrients.

The obtained reverse osmosis water has the degree of purification from impurities up to 98% (in industrial units – up to 100%). According to its properties, it is close to the glacial melt water. However, it should be borne in mind that the water purified by reverse osmosis, contains very little mineral salts.

For there is no single opinion about the benefit or harm of such water for health. Part of physicians believe that its use has a negative impact on the cardiovascular system, the normal operation of which depends on the intake of sufficient amounts of potassium and magnesium. Problem can be solved using additional cartridges, ensuring forced mineralization and recovery of the water structure.

A reverse osmosis filter as compared to the conventional free-flow filter that is considered to be expensive, but this is not always the case. If you are water meters, and you are concerned that three quarters of the water in the filter works to merge into the sewer, keep in mind that one liter of cold tap water in Moscow costs about 3 cents, and in comparison with the use of high-quality filter these costs are immaterial.

What does this all mean?

Reverse osmosis was originally invented as a means to desalt the sources of brackish water or sea water and should be used as a tool for which it is intended.

Contrary to its reputation, reverse osmosis does not eliminate 100% of all pollutants and reduction rates and certifications vary widely depending on the pollutant in question.

OI membranes can be damaged and destroyed by chlorine found in most municipal water supplies and therefore require pre-filtration of carbon.

Reverse osmosis water treatment systems are one of the most complicated types of systems on the market today and require pre-filters, storage tanks, pumps, drain connections and diligent maintenance and testing.
