The standard cartridge produces 3 litres per minute and has a capacity of 9450 litres or 12 month life from initial contact with water. Is there a difference in capacity between the standard and AS001K9 filters?
The AS001K9 filters have a lower capacity of 4000 litres however they will remove more contaminants due to the different media.
Have you had any problems with these units leaking or cracking?
We have a 10 year warranty on our systems and use pressure housings for our bench top water filters so they can be converted to underbench systems in the future if the customer wanted and therefore we have never experienced any leaking or cracking from the units.
Could you please advise the bench hole size required for the tap displayed on this drinking water system?
The tap hole size is the same for all systems. A 10-12mm hole is required.
How do you switch between running water from the tap and from the spout?
The diverter valve that connects to the tap switches between the tap and spout when required.
Does the AS100 accept cartridges from other manufacturers?
If you opt for the 10” system it will accept cartridges from other manufacturers, suppliers, plumbing stores etc
What is Chloramine and how do you remove it from drinking water?Chloramines Removal
Chloramine is now becoming a common disinfectant for drinking water supplies replacing Chlorine in many capital cities including Sydney, Melbourne and Brisbane. This rollout will continue in the future with more and more towns and cities moving to this form of disinfectant. The main reason for this is the considerably reduced level of carcinogenic by-product trihalomethanes (THM’s) formed when using chloramines and it stays in the water much longer, a much higher residual.
The most common form is Monochloramine with concentrations ranging from 1.5 to 2.5 mg/L. Typical residual in Australia is 0.5 mg/L with a maximum of 3 mg/L. It is less effective than chlorine and therefore needs a higher initial dose and longer contact time. Unlike chlorine, monochloramines do not add any taste or smell to the water.
Types of Chloramine
There are 3 forms of inorganic Chloramine; monochloramine, dichloramine and trichloramine. All of these can be formed when water containing or injected with ammonia is chlorinated. The pH and the ammonia/ chlorine ratio determine which kind of chloramines is formed. At a pH <3 mainly trichloramine is formed, at pH 4-7 mainly dichloramines is formed while at a neutral pH >7 or above monochloramine is the main form produced.
The ammonia component of chloramines is also different depending upon the pH of the water. At pH levels >7 ammonium hydroxide is formed, <7, ammonium ion is formed. The ammonium ion is readily removed by cation resin (softener resin) or mixed bed resin however water hardness can substantially affect this. Ammonia is removed preferentially to sodium by cation resin but is displaced by calcium and magnesium (water hardness). Therefore a resin filter will remove ammonia initially but will then release the ammonia when it becomes exhausted with hardness. This could lead to an ammonia spike in the treated water.
Due to the low molecular weight, chloramines and in particular monochloramines are difficult to remove from water by reverse osmosis (RO), distillation, water softeners or resin filters. Distillation or evaporation does not remove chloramines effectively as the chloramines are volatilized and carried over to the product water (distillate). Pre-treatment is required for RO systems to remove chloramines prior to reaching the membrane with specialised carbon filters.
Standard activated carbon (GAC), carbon block or enhanced carbon filters do not remove chloramines. The carbon in these types of filters, whether it be coal, coconut shell or wood based carbon does not absorb chloramines. It removes or reduces them to some degree through a reduction-reaction, its ability to act as a catalyst for the chemical decomposition or conversion of chloramines to chloride (salt) in water. This reaction converts the chloramines into chloride salt and ammonia. This reaction releases the ammonia allowing it to pass through RO membranes and other filters excluding resin. The ability of resin to remove it is dependent upon the pH and other contaminants in the water. The free ammonia can also come in contact with other contaminants in the water and form undesirable Nitrates and Nitrites.
Granular activated carbon (GAC) filters can be used to remove/ convert chloramines however long contact times and low flow rates are required to achieve >95% removal. The cartridge rated capacity will also need to be reduced to 12-25% of the rated chlorine removal capacity for chloramines removal. This is dependent upon the cartridge manufacturer, type of GAC etc. Standard carbon block filters have very low removal/ conversion rates and are not recommended. These filters will not remove the ammonia from the water. For this reason we do not recommend the use of these carbon filters and suggest the use of chloramines reduction cartridges for cities such as Sydney, Melbourne and Brisbane where chloramines are currently used.
Potassium or sodium metabisulphite can also be used for chloramines removal.
Chloramines Reduction Filters
Specialised Chloramines reduction cartridges are manufactured specifically to remove chloramines and ammonia in one. They use a specially developed catalytic carbon to absorb and bond the chloramines. These cartridges need to be installed before or in place of any other carbon cartridges to be effective.
The main manufactures of these filters are; Omnipure Chloramine Reduction, Pentek Chlor Plus, and Filtrex Chloraguard. These are all high quality US made cartridges with a proven track record and available specification sheets.
Can Water Filters Remove Fluoride?
Fluoride is injected into drinking water supplies at various locations around Australia in the form of sodium silicofluoride and sodium hexafluorosilicic. As per drinking water standards this is put into the water at up to 1.5 ppm (parts per million) although the average is 1.0 ppm with possible short (a few minutes or hours) spikes over this due to equipment malfunction or human error. These short term spikes will have little effect on the capacity of fluoride removal filters.
Standard carbon filters of any type are unable to remove fluoride without the addition of special media and even when this media added, they will only remove up to 40%. To remove higher percentages requires reverse osmosis, distillation, resin, alumina or bone char.
Reverse osmosis (ie. Aqua Safe ASRO4) removes approximately 96% and requires resin post cartridges to achieve >99.99% reduction. Distillation removes a higher than 96% but is a batch process and is not considered user friendly and therefore not very popular anymore.
Alumina based systems (ie. Aqua Safe AS280) remove approximately 93% of fluoride but are not suitable for use in bench top systems or incorrectly designed under bench systems as very small trace amounts can under some circumstances leach into the water requiring removal with an additional specialised filter
Bone Char made from animal bones has been used for industrial water treatment for many years although the vast majority is not approved for drinking water treatment. Drinking water certified NSF61 granular bone char is available however, contact time with the media is very important for removal making cartridge design critical for performance. Removal rates tend to vary considerably and multiple (4 cartridges/stages) filters will be required to remove approximately 95%.
Reverse Osmosis is the recommended system for fluoride reduction/removal followed by correctly designed alumina and bone char systems. For reduction levels above 99%, we suggest specialised resin deioniser cartridges installed after a reverse osmosis or alumina system. This type of system may then also include a pH balancing and re-mineraliser cartridge to increase the water pH and add minerals back resulting in a 6 stage water filtration system.
How long does it take to install an AS100 system?
It takes approximately 30 minutes to install the AS100 system including flushing the cartridges ready for use.
What is Fluoride?
The majority of fluoride is either a by-product of aluminium production or artificially produced. It is sold to government and councils around the world saving companies millions of dollar in disposal costs. This chemical is injected into town water supplies to reduce the incidence of tooth decay in children. Many studies have been undertaken over the last 50 years to prove or disprove the effectiveness of the product in preventing tooth decay. From the evidence available there appears to be as many studies concluding the benefits of its use as there are those concluding the dangers and ineffectiveness of the product.
The fluoride used in town water is either a by-product or artificial and man made as opposed to natural fluoride found in rocks and soil. Artificial fluoride is a different product altogether. It is an extremely corrosive dangerous chemical. While many dentist support its use there is an ever growing group of those who don’t.
Fluoride is currently included in just about all available toothpastes. Many countries and towns that have been putting fluoride into their water supplies for many years are now discontinuing this.
The Nazis under Hitler used fluoridation during WWII to reduce the resistance of the masses to domination, control and loss of liberty. The Russians have also used fluoride/fluoridation in the past for the same reason.
There are maximum levels set for the dosing of fluoride into town water supplies, however the chemical has a different weight and density to that of water and can therefore accumulate in water mains overnight or during the day. Water then used from these mains can have higher levels of fluoride.
High levels of fluoride can cause fluoridosis or tooth decay. Fluoride and Fluoridation has also been said to cause cancer based on studies carried out in America in 1980.
Consumers need to make up their own mind as to whether they want to leave it in their drinking water or remove it although it is a difficult chemical to remove and requires specialised filters or reverse osmosis systems.
How often do the filters need to be replaced ?How many litres is one filter able to filter ?
The filters need to be replaced every 12 months or when the filtered volume is reached, which ever comes sooner. The filtered volume varies from filter to filter but is listed under specifications or in the product description.
The downside of chloramine, apart from containing ammonia, is the difficulty in removing it from drinking water. Standard GAC or Carbon Block water filters can only remove 10-25%. Is the AS001K9 effective at removing chloramines over its expected life?
The rated capacity of the filters is generally based on chlorine removal under NSF certification or testing however many of our filters have been de-rated or the capacity reduced to allow for different conditions around the country. The 4000 litre capacity of the K9 & K10 filters is based on chlorine and needs to be reduced to 1800 litres for Chloramine, higher than a normal GAC due to the cartridge design and KDF media.
Does this filter work with low pressure, say a watertank?
The AS100 filter comes standard with a 1 micron filter that requires some pressure to push the water through the filter. Low pressure from a water tank would result in the water coming out very slowly and may take a minute or two to fill a glass. In cases like these it maybe more feasible to either use a 10 micron filter or consider using a ceramic bench top urn.
How long do the filters last on tank water and what is the cost?
The filters will last 6-12 months on tank water. As a general guide we suggest changing them every 6 months due to bacteria build-up being higher with tank water than town water. The cost varies from $32.00 to $90.00 depending upon the type of filter chosen.
Does the AS001C10 Carbon Block 1 Micron filter heavy metal? Whats is the performance?
The AS001C10 filter does not filter out heavy metals, more specialised media is required for this. Our AS001K10 filter does remove heavy metals or our reverse osmosis systems could be used. This does however depend upon the level and type of heavy metals present.
Reduces or Removes: Sediment, Chlorine, Chloramines, Colour, Taste & Odour, Pesticides, Herbicides, Insecticides, THM’s, VOC’s, Cryptosporidium & Giardia, Asbestos, Bacteria, Algae, Fungi. NSF standard 42 certified with a capacity of 10,000 litres.
Does the flouride removing cartridge also remove the contaminants that the other 3 cartridges remove?
The fluoride reduction cartridge only removes upto 40% of the fluoride, 99% of the chlorine and other associated contaminants, heavy metals, Crypto & Giardia, sediment, algae etc.
