Water TreatmentThere are hundreds of diseases that are caused by waterborne pathogens such as viruses and bacteria. There is a need for government and non-governmental organizations to establish treatment plants, especially in the developing countries to promote hygiene of the residents.

The clarifier is one of the main components of a water treatment plant. Here are the two primary applications or roles of this important component of water treatment.

Water Pretreatment

Flocculation and coagulation chemicals are added to the water before it enters the clarifier. The main role of these two reagents is to help coagulate small particles of debris. Ferric sulfate and polyelectrolytes are the main reagents used for this purpose. Once the water enters the clarifier, it is swirled to separate the solids, commonly referred to as flocs, from the water before it flows to the filtration system.

Water Treatment for Human Consumption

Before the water is supplied to your home, it has pass through some treatment processes and tested to safeguard your health. Just like in the pretreatment process, flocculation reagents are added into the water before it is allowed to flow into the clarifier. Inside the clarifier, the solid particles that flocculate are removed, and this makes it easy for the filtration systems to get rid of other toxins. More often than not, the particles settle at the bottom of the clarifier forming a layer of sludge. They should be removed periodically to enhance the efficiency of the entire system.

If you want to purchase a retrofit clarifier for your home, consider the following factors to make an informed decision.


Clarifiers are made in different sizes to suit the diverse customer needs. Consider the amount of water that the system will be treating on a daily basis to choose the right size.

Energy consumption

The modern clarifiers are fitted with energy saving parts that help to reduce electricity usage. Check the specific details of each clarifier available to choose one that is economical on energy.

Finally, consider the cost and durability. The ideal clarifier should be within your budget, durable, and easy to maintaining.
