Side Stream Filtration Systems

What Is Side Stream Filtration?

• Side Stream Filtration is used to remove suspended solids and sludge from a closed loop system, including Biofilms and Pseudomonas (Bacteria)

• Amazon Filters generally specifies a cartridge system, but other technologies such as hydro-cyclones, separators etc are suitable for removing large debris, but lack the high efficiency of cartridges

What Are The Sources of Contamination?

• Corrosion of pipework and components leads to abrasive wear, resulting in fouling of heat exchangers and valve malfunction

• The bacteria and biofilm can be chemically treated with biocides which stops bacteria growth, but the dead material (sludge) only adds to the re-circulating mass

• Amazon Filters Side Stream systems are a practical and cost effective solution to these problems

Where We Fit Side Stream Filters

• Typical systems for side stream filtration are Low Temperature Hot Water (LTHW), Chilled Water (CHW) and Condenser Circuits

• Each system will generally have primary and secondary circuits, supplying radiators, heating coils and air conditioning units

• Examples - Kings Cross Station, Paddington Central, State Street Bank, Great Ormond St Hospital, New Olympic Stadium, T5 Heathrow

What Is a Typical Closed Loop Circuit?

Side Stream System Design

• 5 -15% of primary circuit flow rate• Amazon 60 Series Filter Housing• SupaSpun II and SupaGard Cartridges • 2 bar minimum working pressure, or booster

pumps may be required• Cartridge change–out recommended at 1bar

pressure differential• Typically installed inside Building Plant Room
