BSRIA Closed System Water Testing Screen
Feedwater can now offer Full BSRIA compliant water analysis for Micro and Chemistry parameters to measure the control levels in your closed heating or cooling system.
Sizing a Closed System Water Volume
If you are having trouble trying to size your closed heating or chilled system, our handy sizing ‘rule of thumb’ may help when calculating chemical inhibitor dosing.
Testing Closed System Water
It is important to test your closed system regularly, especially for chemical reserves, Feedwater offer a range of Chemistry and Microbial tests performed by our in-house Micro and Chemistry labs. We can also provide test kits for you to test your own closed system water for inhibitor reserves and other parameters.
Coagulation and Flocculation – Process Fundamentals
Suspended matter in raw water supplies is removed by various methods to provide water suitable for domestic purposes and most industrial uses. The suspended matter can consist of large solids which settle by gravity alone without any external aids and ‘non-settleable’ material often colloidal in nature. Removal is generally by coagulation, flocculation and sedimentation. The…
What is Corrosion?
Corrosion is the reversion of metals to their natural state by oxidation, an electrochemical reaction that causes a loss of the metal structure. The site where corrosion occurs is called a corrosion cell. Corrosion may take a variety of physical forms. General corrosion occurs when corrosion cells are spread broadly across large surface areas; pitting…
Biocides and Biological Control with Feedwater Chemicals
Broad Spectrum Biocides offer an encompassing solution to microbiological control Biocides can be useful for the control of microbiological organisms which can become very attached to the environment of your water systems be they cooled or chilled or even low temperature closed systems. This can be bad news as some bacteria such as Legionella can…
Choosing your Closed System Corrosion Inhibitor
Corrosion inhibitors for Closed, heating and cooling water systems Corrosion inhibitors are an essential to ensure the longevity and efficient operation of your closed heating or cooling water system. The two main types of treatment for closed systems are nitrate or molybdate based corrosion inhibitors. In certain circumstances using a Tannin based inhibitor may be a better choice if,…
