Top 15 Water Treatment Companies in the USA with Capacity, Plant Location, Specialization, and Services or Products

A drop of water is worth more than a sack of gold to a thirsty man

Almost 60% of the human body is water, imagine if this water is contaminated? Clean drinking water is the right of every human being. Nowadays the quality of water decreases in every region. Industrialization, agriculture waste, drainage water are the main reasons to make water pollution. In that case, it is a really difficult job to provide a pure and hygienic water supply to cities and towns.

We can see many industries releases their wastewater directly into the nearest water source, this is so much harmful to the environment as well as leaving organisms in the water source. This same chemical added water absorbed in soil and groundwater is also get contaminated.

Contaminated Water and its Causes

Natural water reservoirs like a lake, dam, river are now infected due to human waste, industrial waste and this situation is present everywhere. In such a situation drinking water directly from sources like rivers, dams or even borewells is harmful to humans. This water contains health affecting elements like lead, fluorine, mercury, and so on. Those harmful elements can cause many severe health issues such as Cholera, Typhoid, Diarrhea, dysentery.

Purify the water before use it for drinking is so much important to avoid any kind of health issue. Every government has a responsibility to provide its people with pure and filtered drinking water. Water filtration is the only option so that we can have a glass of safe water to drink.

Globally many water treatment plants established since the last century and their only sole purpose are to provide clean and purified water to the people. The United States also suffers severe drinking water issues in response to supply people with safe water.

Now there are many water treatment companies are working in the US and globally. Basically, water treatment companies work on wastewater, these companies collect water from many large industries or factories and filter it so that it can be reused for agricultural use or it can be released into the river and any other water resources.

Why water treatment is necessary?

The entire world is facing drought, less rain, dry spell, and many other issues regarding water shortage like decreasing groundwater levels, decreasing dam water levels. This is a not ending and unanswerable situation we are facing. But the demand for fresh water is increasing at a high speed.

Industrialization, urbanisation, construction, manufacturing, and agriculture need a high volume of water every day. We are facing a freshwater shortage at its limit. In such conditions, water treatment and its reuse is the only way remains.

Following are some of the types of water treatments available

1. Wastewater treatment

2. Saline water treatment

3. Sewage treatment

4. Demineralization treatment

5. Reverse Osmosis water treatment

These are various treatments we can use to clean and purify the water so that we can reuse the contaminated water for industry or agricultural purposes. These types of water treatment only take place at the industry level. There are so many top players are working in the water treatment industry. Some of them are mentioned above.

Steps of Water Treatment

1. Collection of contaminated water: This step includes the collection and storage of water for treatment. Water collection tanks are located on the choice that where we are reusing the water or releasing it on the river or other water resource.

2. Water separation: Water separation takes place using gravity, solid waste gets removed from the water.

3. Chemical Adding: Adding chemicals can control bacterial multiplication.

4. Coagulation: The coagulation process is so much important step, it removes, many particles such as dissolved organic carbon.

5. Water Filtration and disinfectant: Filtration process includes, many layers of process in which water to flow into UV, RO demineralization, and water disinfectant.

6. Storage and distribution: Once the water treatment is done at this state one can store the water for reuse in industry or agriculture or can be released into the nearest water reservoir.

Drinking-Water Treatment Devices

1. Activated Carbon Filter:

Primary Use: It removes chlorine, general taste, and odor.

Limitation: Does not remove bacteria and inorganic compound

2. Reverse Osmosis:

Primary use: removes maximum contaminants than any other filter, removes some bacteria and viruses

Limitation- Does not remove chloroform, 100% chemical cant remove, required a large amount of water

 3. Ion Exchange:

Primary Use- Removes positively charged ions, inorganic compounds, manganese ions, arsenic, chromium and also removes some negative charges ions such as nitrate, sulfate.

Limitation- Regeneration required.

 4. Filtration:

Primary use- Removes small particles, sand, some bacteria.

Limitation- Filter replacement based on water concentration.

5. Distillation:

Primary Use– Removes dissolved minerals, metals, and toxic chemical.

Limitation- Produces limited water, the large unit requires large space, not effective against some chemicals.

 6. Aeration:

Primary use- Dissolved gases like radon, methane, dissolves iron and methane.

Limitation- waste air must be vented from the house, post-treatment necessary.

7. Ultraviolet Radiation

Primary use- Removes bacteria and virus.

Limitation- Not recommended in highly contaminated water.

 8. Ozone:

Primary use- Removes some color, taste, odor, and bacteria

Limitation- Not effective to remove some large cysts and metal

 9. Activated Alumina:

Primary use- arsenic and fluoride compound get remove

Limitation- required post-treatment for bacterial removal

10. Chlorination:

Primary Use- viruses and bacteria can remove, manganese and sulfur compounds remove

Limitation- Test and odor, not change

11. Oxidation:

Primary use- use to remove bacteria and virus, dissolve iron, manganese, and sulfur bacteria

Limitation- requires more time and monitoring, some oxidation causes skin irritation

12. pH adjustment:

Primary use- raise water pH to drinking level, neutralizing filters

Limitation- pH adjustment does not treat any bacteria or viruses

We can not perform a single activity without water, from our body requirements to every day task and from agriculture to manufacturing every place of task need water. Our planet contains a large source of water but this is not useful in everyday life. From drinking purpose to industrial purpose water treatment is so much necessary. We can not use salt water directly from the ocean.

We have described many water treatment companies in the USA, and there are so many other companies spread worldwide, we are also covering some of the water treatment companies from different regions as follows.

Final Words

All our dependency is on freshwater, but now freshwater resources are shrinking and get overused. Many of them are contaminated by sewage water outlets, industrial outlets, or by agricultural waste. Now, this is high time we have to filter this water and reuse the same. Otherwise, the day is not so away when we won’t have enough freshwater to drink. So the water treatment and its reuse is so much important.
