List of Five Chemicals used in Wastewater Treatment Plants
Waste is always inevitable to avoid in the process of Industries and Manufacturing. The chemicals used in treatment are no exception, since wastewater treatment is a process of removing dirt and waste. Chemicals offer a soluble solution to industrial waste which is more environment-friendly.
Listed below are chemicals that have valuable application to the
wastewater treatment:
Aluminium Sulfate
One of the most common
chemicals used in wastewater treatment plants is aluminium sulfate. Aluminium
Sulfate acts as a purifier in the wastewater plant for the wastewater.
Aluminium Sulfate is soluble and easily reacts to the chemicals in the
wastewater. As a result, it break downs insoluble and hazardous chemicals.
It also aids in regulating the pH level of chemicals, making wastewater less dangerous to the environment. Despite the many benefits of aluminium sulfate, excessive use of the chemical can also backfire. If the levels of aluminium sulfate are above the recommended one, then it will become a health hazard which can cause damage to the environment. Nevertheless, aluminium sulfate is still an important chemical in the water purification process.
Sodium Aluminate
The next chemical used in
wastewater treatment plants in India is sodium aluminate. Sodium aluminate is a chemical
that belongs to the inorganic compound. The liquid form of sodium aluminate
works well as a phosphorus remover. Wastewater contains a lot of phosphorus
which is hard on the environment. To avoid that, sodium aluminate functions to
elevate the pH level of wastewater with extremely low pH.
Since sodium aluminate is
only soluble with some chemicals, we have to be careful to only use it in the
right dosage to avoid exploitation and damage to the environment.
Polymer
Polymer is a chemical that
is known to have many functions in the industry, especially those related to
plastic. It has its benefits as a chemical in wastewater treatment. The
function of polymer is to harden any solid dirt and dissolve in diluted water
to free these materials in suspension.
In order to use polymer in
wastewater treatment, people need to dilute polymer with water with a
concentration of 0.5 per cent. By using polymer, any waste that has the potential
to block water will have better treatment and the wastewater will be cleaner
than before.
Sodium Hydroxide
Another chemical that works
in the wastewater treatment plant is sodium hydroxide. Sodium hydroxide belongs
to an inorganic compound that has the symbol NaOH. In wastewater treatment
plants, sodium hydroxide has many functions such as pH stabilizer, metal
precipitant, and alkaline cleaner.
The combination of sodium,
hydrogen, and dioxide makes this chemical work well for wastewater treatment,
especially for removing harmful waste and pollutants. By using sodium
hydroxide, more safe wastewater is possible.
Ferric Chloride
A chemical that is
frequently used in wastewater treatment plants is ferric chloride. Ferric
chloride is a corrosive chemical used for purification and sewage treatment.
The main function of ferric chloride is to remove metal substances from the
waste which are highly harmful to the environment and living beings.
