What is Chemical Dosing in Wastewater Treatment?

Water treatment is becoming more important than ever, as rising populations around the globe are inevitably increasing the need for clean, usable, and consumable water.

As fresh water only makes up about 3% of the earth’s water, recycling wastewater is potentially more useful in terms of sustainability than other methods of conservation.

The problem with recycling water is that wastewater is often mixed in with chemicals that make it unusable when it comes to most of our needs.

Chemical dosing can help us to manage use of water equipment that is designed to turn wastewater into useable water.


What is Chemical Dosing?

Water treatment systems use chemical dosing to treat wastewater, and there are several different types of dosing that can be used.

Whilst each of these processes work differently, they all remove the high levels of chemical content present in the wastewater being sent through the system.

This means that, whichever is most appropriate, each process is designed to provide the same result: recycling wastewater so it is fit for use in a plethora of contexts.


How does it Work?

At wastewater treatment works, chemical dosing is done through the automatic injection of reagents into the system that processes the water, reducing phosphorous concentration, and settling pH levels.

Identifying which types of chemicals are dissolved in the water is the first part of this process, as it helps determine which chemicals should be used to allow the water to become usable again.

Through use of automated systems, the amount of dosing required is monitored, and the level and speed at which the chemicals are administered are adjusted accordingly.

The System Itself

When building a system of any type, there are many variables that determine aspects of its design, including space, location, and the size of the system itself, as well as factors specific to the process of dosing itself, such as which chemicals are being used and how they behave in the process.

The chemicals are generally housed in at least two tanks to allow for maintenance, and the water is run through several filters to reduce debris, following which it reaches the dosing point itself.

The wastewater is then introduced to the chemicals in the tanks, which are released at a speed and pressure that is determined by the amount of chemicals that need to be removed.

Finally, the processed water is calibrated to ensure it meets the standards required for use. If it doesn’t, it is simply sent through this process again.
