Upon purchasing your cooling tower,evaporative condenser, or ammonia condenser water treatment is often overlooked. New plant and facilities typically are at the point where the system is ready to began operation and not one thing has been addressed for your cooling water treatment needs.
Here is a breakdown what you will need to get started:
Corrosion and Scale Prevention Chemical - The factors that decide the type of scale or corrosion chemical required is based on your make up water city hardness and alkalinity. Most city locations have mild hardness conditions and neutral pH levels. If this is the case ChemWorld 1334 is a good selection for controlling scale and corrosion. If you have hard water, high silica levels you will require a different cooling tower chemical.
Cooling Tower Biocide - Cooling water process systems will product on going bacteria such as aerobic and anaerobic bacteria in the form of slime, sludge, algae, and/or Legionella. A good water treatment biocide program will control your bacteria development. Depending how critical your system is you may choose to use one oxidizer chemical or a dual biocide treatment program (non oxidizer and oxidizer chemical). An example of an oxidizer chemical is Bromax 7.1. A good example of a non-oxidizer is Isothiazolin.
Cooling Tower Test Kits & Cabinet - For new startup we recommend purchasing the complete Cooling Water Treatment Test Kit. This will have all the required testing kits upon startup. You will need a test kit cabinet. Failure to put your kits in one area will lead to everything be lost or scattered by the end of startup.
Pretreatment Chemicals - Prior to implementing your water treatment startup, the system should be cleaned from greases and debris. ChemWorld Q-Alk is ideal for cleaning the system, just before start up.
Chemical Pumps - We strongly recommend using Stenner Pumps for most cooling tower chemical applications. They prime themselves and are easy to use.
