PURIFIED WATER SYSTEMS

 
Purified water systems are used by a diverse range of industries and the design of the system and the purification equipment used will depend on the users’ operation. For instance the needs of a hospital renal unit will be very different to a microchip manufacturer. Whether it is a softener, EDI system, RO membrane, UV tube or storage tank, Amazon Filters has products to help ensure the equipment operates reliably and the required water quality is achieved.

Raw Water Softening

Raw water is likely to contain a diverse range of organic and inorganic material. Removal of the bulk of the particulate contaminants is important to ensure the effectiveness and life of the resin beds used in Water Softeners. Amazon Filters recommends the use of DuoLine bags or SupaGard meltblown depth filters rated between 10 - 100 µm for raw water filtration and protection of softening and other pre-treatment systems. 

Deionisation System Trap Filters

Twin bed, mixed bed, EDI and RO systems rely on effective filtration upstream and downstream. Prefiltration is required to protect the resin beds from particulates that could reduce efficiency and life. Filters are also used as ‘traps’ on the effluent to capture any shed resin that will contaminate downstream plant. SupaSpun II, SupaPleat II, Contour or SupaPleat FFC filters rated at 5 - 10 µm are commonly used upstream and 1 - 5 µm rated filters downstream.

Pre and Post Ultraviolet Treatment

To ensure effective control of bioburden, UV units rely on filtration of the feed water to remove particulates that will produce ‘shadowing’ and regions where full UV penetration is not achieved. This will reduce the efficiency of the UV treatment. Typically SupaSpun II, SupaPore PPG or SupaPleat FFC filters are used for this application.

Point Of Use (POU) Filtration

Filters are often installed at Point of Use to remove fine particulates and bacteria that may have been introduced into the water by the distribution system. These may be attached to take-off points or located at the inlet to the equipment the purified water system is feeding. Amazon Filters supplies a range of SupaPore VP cartridge and capsule filters rated at 0.03 – 1.0 µm for these applications. Where endotoxin control is also required we are able to supply specialised cartridges.

Cryptosporidium Removal

Cryptosporidium contamination is a growing concern for water supply companies and manufacturers of drinks and food products. Amazon Filters supplies a range of cartridges that have been qualified for effective removal of cryptosporidium. Both SupaPleat II and SupaSpun II filters are used in water systems for cyst control. SupaSpun II filters rated at 1µm absolute are available in standard format and as SupaSpun II R31, a special DWI Regulation 31 compliant grade. SupaPleat CRY grade filters are offered as standard pleated elements and as the large diameter SupaPleat FFC version for higher flow systems.


Holding Tank Vents

To maintain the quality of stored water Amazon Filters recommends the use of vent filters. For particulate control SupaPore PPG filters rated at 0.6 - 5 µm are recommended. Where protection from airborne bacteria is required, PTFE SupaPore TP filters rated at 0.2 µm are used. Amazon has designed the sanitary 71 Series housing for critical venting applications. We also offer jacketed heated housings for hot water systems to prevent wetting of the filter by condensation, therefore maintaining full air flow.


Custom Products

Amazon Filters is able to design, develop and manufacture a range of cartridge and capsule devices containing filtration or separation media, to meet the specific requirements of water treatment system manufacturers. For more information contact Amazon Filters.
