SIDESTREAM FILTRATION

Download Sidestream Filtration Application Guide

Sidestream filters work by filtering a small percentage of full flow (5 – 15%) so that the complete system volume is filtered 2 – 3 times every 24 hours. Sidestream filters provide an excellent solution for filtering high volumes of CHW and LTHW or MTHW.

It must be noted that filtration combined with water treatment is part of a preventative maintenance program and the primary purpose is to increase the operational life of mechanical components. While a correctly designed water treatment program goes a long way in controlling corrosion, scale and biological contamination, suspended particles in a closed-loop water system can reduce the effectiveness of water treatment chemicals and contribute to/accelerate corrosion or biological growth. Scale, corrosion, biofilm and suspended solids interact with each other and can result in ongoing operational problems.

Siga filtration offers a range of filtration products for CHW, LTHW and MTHW circuits. These filters have been used successfully on both new installations as well as extremely corroded and contaminated older systems where filters did not form part of the original installation.

WHY USE SIDESTREAM FILTERS?

– Cost-effective as compared to installing a large filtration system to handle the full flow rate.
– Minimum disruption during filter change-outs and maintenance.
– Tried and tested technology which has been successfully used to maintain healthy HVAC water systems.
