Coagulants are typical metals based and their primary purpose is to neutralize the charge so that the particles don't try to repel each other and remain in suspension.  Once neutralized, the particles will typically exhibit a higher likelihood of settling. 

Once the particles have been neutralized a flocculant can be added to help bring the particles closer together and for clumps to make removal even easier.  We have a wide array of flocculants

Nearly every cooling system is comprised of a significant amount of metal piping and process equipment that spans facilities.  Preventing the corrosion of this piping helps protect the assets from premature failures.  We have many different types of corrosion inhibitors, each with their own conditions where their use is warranted.

Cooling towers are open systems, subject the variables introduced from airborne contaminants.  Also with the airborne dirt there is the bacteria that can adhere to the surface of the systems.  We have a variety of dispersants to help keep these contaminants from depositing on the surfaces so that they don't promote under-deposit corrosion or harbor bacteria that can raise the risk of disease.
