In this blog, we will cover the four types of water treatment plants, how they work and the many industrial applications of each type.
How does a water treatment plant work?
This water treatment plant works on the principle of ion exchange. In these plants, special ion exchange resins are manufactured that help to replace any mineral salts in the water. There are two types of resins- one is an anion one while the other is a cation one. These former resins release hydroxyl ions which are negatively charged while the cation resins release hydrogen ions that are positively charged.
What happens to wastewater in digestion tanks?
In the digestion tanks, the sludge is heated and mixed. Another important thing that happens here is the production of biogas, which the wastewater treatment plants can reuse, in the production of electrical or thermal energy which is another huge benefit to the environment.
Why is water treatment important?
It has become more important and critical than ever in the 21st century to have clean water and environmentally friendly industrial activities. Most industries use water in one way or another in their processes. Once this water is used, it needs to be treated before being disposed of so that it causes no detrimental impact to the environment, whether it is disposed into the natural environment or into sewage networks, the chemical and physical properties of the wastewater need to comply with current regulations in order to protect one from legalities as well. Here is where a water treatment plant becomes the need of the hour as it can help commercial and industrial facilities become environmentally friendly as well as compliant in their wastewater disposal.
How does wastewater drain to a water treatment plant?
The first step in this water treatment plant is that the wastewater drains to the plant with the help of gravity through the main sewer system.
Where does wastewater sludge go?
During this stage, the excess sludge (any excess bacteria in the wastewater) is pumped out and moves to the settling tanks. These settling tanks enable the sludge to settle and then moves to digestion tanks .
What is waste water?
Wastewater is the water that originates from water used in domestic, agricultural, industrial as well as medical or transport activities.

Wastewater treatment plant power consumption can range anywhere from 50k BTU/gallon each day to less than 5k, depending on the types of water treatment plants in question.
What is an ASP plant?
Activated Sludge Plant (ASP) An activated sludge plant , also known as an activated sewage plant or ASP, uses a wastewater treatment process that involves adding oxygen and microorganisms to organic pollutants. These microorganisms used in wastewater treatment cause the pollutants to oxidize, creating a sludge type substance biologically.

To remove specific contaminants known to affect the area.
What is distillation system?
Distillation System: This is a process that takes impure water and boils it. The steam is then collected and condensed into a separate container. This will leave many of the solid contaminants behind.
What is distilled water?
Distilled water is water that has been purified by passing through one or more evaporation–condensation cycles, and contains essentially no dissolved solids. Usually contains less than 5.0 ppm of TDS.
What is the best way to improve the taste of water?
If you want to improve the taste and smell of your drinking and cooking water, a POU (point of use) system installed at your kitchen sink is a great choice. Reverse osmosis water filter systems are an economical, simple solution. Reverse Osmosis can remove lead, iron, fluoride, nitrates and dozens of other contaminants. In addition, an RO system can greatly improve the taste and the quality of your water by removing chlorine and other offensive tastes.
What is a reverse osmosis system? How does it work?
Reverse osmosis water filtration is a chemical-free, economical way to improve the taste and odor of your drinking water. As mentioned above, an RO system produces clean, filtered water by forcing tap water through a semi permeable membrane and the filtered is directed to a storage tank. The impurities that are separated from the water molecules are flushed down the drain. A reverse osmosis system consists of both pre and post filters which add additional contaminant removal. To learn more about the reverse osmosis process, we provide details here .
What are Sediment Filters?
Sediment filters can act as a barrier against grit and particulates that can clog your water filter system , cause issues for household plumbing, and reduce the life of water-using appliances.

How to know what is in your water?
You might also consider getting water tested or find the report to know exactly what contaminants are in your water. If you receive water from a municipal water supplier, then you can review your local " Consumer Confidence Report " (CRC) to learn what is in your water. Each year, public water suppliers are required to provided a CRC. If you are on a private well, you can send off for a water analysis from a certified laboratory.

What happens when chemicals are added to water?
Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. Sedimentation.
Wastewater Treatment Plant
Sewage Treatment Plants
- These plants remove contaminants/sewage waste from households, commercial buildings and sometimes even get an inflow of commercial wastewater too. It can also receive rainwater and debris from sewers. STPs play a critical role in keeping residents healthy and safe by cleaning wastewater with a bunch of chemical, physical and biological procedures before disposing it int…
Effluent Treatment Plants
- As previously seen above, sewage treatment plants provide initial treatment for domestic or municipal purposes. Effluent water treatment plants, on the other hand, are quite the opposite as they treat industrial effluent, that is, the wastewater that occurs as a result of the flow of byproducts from industries.
Demineralization (DM) Treatment Plants
- In water treatment for industrial purposes, demineralization typically involves the complete removal of dissolved solids or minerals from feedwater (i.e., deaerated water that is supplied to a boiler from a tank for conversion into steam) or process streams.
Reverse Osmosis (RO) Water Treatment
- The principle of reverse osmosis (RO) functions on the filtration method that results in the removal of a large number of contaminants and impurities from wastewater by applying pressure to it when it is on one side of a membrane.
