Did you know that industrial wastewater makes up over 20% of water usage across the globe? With that much water going to industrial uses alone, it is easy to see why water treatment is so important to the health of our communities. Water treatment systems go a long way towards keeping people safe and communities thriving, through this process.
But how does a water treatment plant work? What steps does it take to make used or dirty water clean again?
Keep reading to learn about the water treatment process and how it takes dirty or polluted water and makes it clean again.
Why Is Water Treatment Important?
There are a lot of health risks that come with consuming unclean or contaminated water. The cleanliness of the water is governed by the Environmental Protection Agency, which sets the limit on the levels of contaminants.
Some of the chemicals and organisms that are in untreated water can have major impacts on the health of those who consume it. They come in the form of neurological issues, gastrointestinal illnesses, and reproductive issues.
According to the Center for Disease Control, the top 10 most common contaminants in the water in the United States are:
- Hepatitis A
- E. Coli
Water treatment companies thankfully have treatments for handling these contaminants and preventing the spread of harmful illnesses.
Types of Water Treatment Systems
There are different water treatment systems that are built to focus on or specialize in certain types of contaminants.
All of these treatment systems have the same general goal of taking contaminated water and making it clean again.
Effluent Treatment Plant
A top water treatment choice for large pharmaceutical companies and chemical industries, effluent water treatment systems are great with toxic and non-toxic contaminants.
Effluent treatment plants are also a great water treatment option when it comes to helping the environment. It allows you to take contaminated or polluted water and make it reusable for other purposes.
The process of effluent water treatment removes dirt, grit, pollutants, chemicals, and debris from the water. This form of water treatment is the best for the environment because it removes everything harmful from the water before it goes back into nature.
Sewage Treatment Plant
Sewage treatment plants are also known as domestic wastewater treatment and are meant for treating sewage from households. The process uses physical, biological, and chemical methods.
These methods remove both physical and biological contaminants from the wastewater. This makes the water reusable
Micro Bubble Diffusion
This water treatment option works differently than others on the market. Microbubble diffusion works by supporting aerobic bacteria in the water which helps with the growth of oxygen.
Dissolved oxygen helps the aerobic bacteria breakdown waste in the water. The more oxygen in the water, the more solid waste will be broken down and the water treated.
It is a beneficial option because it is a natural and environmentally friendly option for water treatment that is shown to work. It is also a much more cost-effective option for water treatment compared to other treatment types.
This also makes it a great option for well water treatment or use as a home water treatment system.
The Steps of Water Treatment
The steps of water treatment are slightly different depending on the water plant and the types of contaminants in the water, but for the most part, they are the same.
Here is a look at each of the four steps of the treatment process.
1. Coagulation and Flocculation
Coagulation involves positively charged chemicals like aluminum sulfate being introduced to the water to balance the negatively charged chemicals from solid waste in the water.
Once the charge in the water is neutralized, micro flocs form after binding together with the chemicals that have been added to the water.
After coagulation has occurred, flocculation begins. Flocculation is a gentle mixing that causes the micro flocs to collide and form visible particles. As flocculation continues these flocs continue to grow in size and strength.
Sedimentation begins when the matter and pathogens in the water settle at the bottom. The longer the water sits peacefully, the more solid particles will fall to the floor.
Coagulation and flocculation make the sedimentation process easier because it makes the particles larger and heavier. This causes them to sink quicker.
For treating a community’s water supply, sedimentation must go on continuously in sedimentation basins. It is a necessary step that must be taken prior to the next two steps.
Now that the particles have settled at the bottom of the basin, the clear water is ready for treatment. Filtration is needed because at this stage there are still small particles in the water that contain dirt and viruses that need filtering.
Filtration has the water pass through physical particles like sand or gravel. Slow sand filtration combines biological, physical, and chemical treatment into one process.
Rapid sand filtration is a physical purification step in a larger process. It is a costly process that uses many power-operated pumps and regular cleaning. It also requires skilled laborers and continuous energy to keep running.
The final step in the water filtration process involves the addition of disinfectant to the water. This oxidizes the water and kills any leftover bacteria or parasites.
The disinfection process also protects the water for its journey through pipes and tunnels to the homes and businesses that are going to use it. The disinfectant chemicals protect the water from germs on its journey.
Do You Need Water Treatment?
Water treatment is necessary for the health of the environment and the people living in it. It is an involved process that works to remove solid particles from the water while also eliminating harmful organic matter.
The process removes the harmful chemicals and bacteria in the water and makes it safe to consume or clean with. Water treatment is essential for keeping society going and our friends and families healthy.
