Buildings & Facilities Management

Estates managers and engineers are charged with controlling the building services that affect the building systems and therefore the processes and staff within.

Services such as heating, air-conditioning, humidification, drinking water provision, cooling towers, closed loop water circuits, ventilation and many more fall under their remit.

Some companies will sub-contract this service provision to a Facilities Management company who will source Filtration and Water Treatment systems and products on their behalf. There are numerous applications within this market sector, we have included some of them below. double_down1600.png

Closed Loop Circuits

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 Pleated cartridges continuously removing contaminants from the whole loop.

Point-of-Entry (POE)

Filtration on the incoming water to site/building is used to protect the whole building and the processes and staff within. This is common practice for water sources other than mains feed and is also used with mains feed when the site is for instance a food factory, hospital or beverage manufacturer.

Depth cartridges protect pipework and equipment from clogging, Surface cartridges are used to remove specific contaminants such as cryptosporidium and bacteria, Softening systems prevent scale build-up, UV systems reduce biofilm growth rates and in some cases RO systems are used if the source water has a range of unwanted contaminants.

Point-of-Use (POU)

The most common applications for POU Filtration and Water Treatment are for drinking water where there are options of Carbon cartridges and RO systems, these applications would also include plumbed-in water coolers.

On sites where immunocompromised patients or elderly residents or where an outbreak of Legionella or other bacteria has occurred, the best and quickest solution is the use of Shower and Tap filters that remove bacteria at the POU.

Boiler Feed

Industrial boilers used for heating and other processes all benefit from the use of Softeners and RO quality water to reduce the number of ‘blowdowns’ required and therefore save money from energy and chemical de-scaling bills.

Kitchen and Laundry

Softened and/or RO water is used to provide clean water to steam ovens, protecting spray nozzles from scaling and improving the taste of the food produced.

Laundries often benefit from using purified water for better cleaning results and efficiency in boiler feed.

Heating, ventilation, air-conditioning and other systems such as humidification typically use Filtration and Water Treatment techniques to ensure efficiency and reduced maintenance with these critical systems.
