Flocculation/Coagulation

We have experience in flocculation/coagulation systems for a range of water treatment processes ranging from river water to dam water.  In these systems, flocculation/coagulation are critical in the pre-treatment step prior to sedimentation and/or filtration.  If not used the water produced would not have been clean or suitable for its intended use.

About Flocculation/Coagulation

Flocculation and coagulation are methods to remove particles in water and is normally part of a pre-water treatment process to be followed by sedimentation and/or filtration.  It is typically used to remove suspended and colloidal solids such as clay from water sources such as that from rivers or dams.  It can also remove some organic matter, colour and microorganisms such as bacteria, viruses and algae.  It can be used to treat industrial waste water prior to discharge or it can be used to clean up water for consumption.   It is a powerful tool in water treatment.

Typically, the “dirty” water needs to be treated with these chemicals otherwise it will pass through filters and other processes.  The water will still be dirty.  The suspended solids are often far too small to be stopped by filters but if trapped it will be at the expense of the performance of the process.  The message is, you need these chemicals to clean the water.

Flocculation and coagulation chemicals rely upon agglomerating/clumping together of particles.  These heavier particles will now settle producing 2 zones, a clear layer that is normally removed and used in subsequent steps, and a sludge layer that will remain in the vessel and will periodically need to be removed.

These chemicals can be simple compounds, they can be polymers, and the challenge is to choose the right one and at the right dose.
