Pre-commissioning of closed loop water circuits occurs after installation and before use, to clean pipework, removing debris that can abrade surfaces and encourage biofilm growth.
Biocides and water are often pumped around the circuit with any debris being collected by Depth or Surface cartridges. For ongoing cleanliness, side-stream filtration units are installed whereby a proportion of the water passes through Depth or Surface cartridges continuously removing contaminants from the whole loop.
Stages of Filtration & Water Treatment
Particle Removal
Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.

SPECTRUM TruDepth Standard Spun-Bonded Cartridge
Boasting WRAS approval over the ESP, the TruDepth Standard is the best value option for general particulate reduction. With a recognisable mini-grooved construction, the SSP has a higher surface area and enhanced dirt holding capacity over the TruDepth Economic cartridge (ESP).

SPECTRUM Premier Pleat Polypropylene
The most popular and versatile cartridge in the Premier Pleat range. Many applications benefit from using this high efficiency, 4 layer cartridge. WRAS approved.
