Product Faqs

Ask a Question

  • Will my Doulton or British Berkefeld filter element remove Chloramine?

    Chloramine may be removed by passing through a bed of activated carbon, but requires much greater contact time with the carbon than chlorine, so a slow flow rate through the carbon must be ensured.
    Unfortunately although the Doulton or British Berkefeld, Supersterasyl, Carbosyl, Supercarb and Ultracarb filter elements contain activated carbon, they may reduce levels but will not remove chloramine because there is insufficient contact time with the carbon.

  • 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.

    Ammonia

    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.

    Removal

    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.

  • How do I clean a candle?

    Use a scouring pad (similar to 3M ‘Scotchbrite). Ensure that the end of the plastic mount does not come into contact with unfiltered water and dirty hands. Rubber gloves are recommended to be used during cleaning and NEVER use soap or detergents!

  • My filter candle blocks up too regularly, what can I do about it?

    In some water conditions, there is so much particulate or turbidity in the supply water that the candle becomes blocked much more quickly than in normal conditions. In these circumstances, it is beneficial to use a pre-filter upstream of the ceramic candle; - this prevents the candle from becoming blocked too quickly, minimises cleaning and so extends the life of the ceramic filter.

  • When does a ceramic filter element need replacing?

    Ceramic Only
    Once cleaning fails to restore the flow. Although, each individual candle does have a recommended capacity when used in normal conditions. The capacity for a specific element is quoted in within
    the section dedicated to each filter element’s construction and performance.
    Combination Filter Elements
    In dual function systems cleaning the ceramic will not extend the life of the internal material. For example: the ‘life’ of the extruded carbon block in the Supercarb filter elements is determined by the concentrations of chlorine and/or volatile organic compounds in the supply water. In most cases, the filter element should be replaced after 6 - 12 months of daily use or 1000 US gallons. The particulate and turbidity concentration in the supply water governs the life of the ceramic, which may exceed or not achieve the capacity of the carbon insert. Whichever point is reached first governs when the filter element requires replacing – the six months usage or the ceramic becoming blocked to the extent where cleaning does not restore the flow.

  • I don’t have a flow meter to gauge the amount of water that my filter has treated. How can I estimate how much water has passed through the filter?

    On average a family of four uses approximately 8 litres of water per day for cooking and drinking, so based on 10 litres/day for four people the life of your filter can be estimated in time rather than capacity.

  • Do I need to sterilise the candle after cleaning?

    Only the Standard candle needs to be sterilised. After you have cleaned the Standard candle, place it in a container of water. Bring the water to a boil for 20 minutes. Allow it to cool before replacing the candle in the filter housing. All the other filter elements are manufactured with either the ‘Sterasyl’ or ‘Carbosyl’ ceramic shells, which contain trace amounts of silver to prevent microbiological growth. These elements should
    NOT be sterilised after cleaning. In the case of combination filter elements, boiling will damage the internal components of the element.

  • How do I keep my filter housing clean?

    The filter housing is best cleaned by unscrewing the body from the head and wiping the surface and the inside of the body with a soft cloth dampened with warm water. IMPORTANT – DO NOT ATTEMPT TO CLEAN THE FILTER HEAD, WHICH COULD CAUSE CONTAMINATION OF THE FILTERED WATER.

  • What happens if I leave the filter unused for a period of time?

    If normal use of the filter is interrupted by holidays or vacations, growth of harmless heterotrophic bacteria may result in a ‘flat’ or ‘stale’ taste for a period of time when use of the filter resumes. This is especially true for the filter elements that contain activated carbon such as the Super Sterasyl (contains granular activated carbon), the Supercarb and Ultracarb (both contain an extruded activated carbon core). Flushing the filter system for several minutes after any prolonged period of inactivity should eliminate the problem.

  • What is the difference between temporary and permanent hardness in water?

    Hardness caused by the presence of positively charged metal ions and total hardness is measured as the equivalent of milligrams per litre of calcium carbonate. There are two forms of hardness, temporary hardness which only contains metal carbonates and bicarbonates, the most typical being calcium carbonate. Temporary hardness is precipitated from water when heated and is responsible for the furring of heating elements and metal pipes. Permanent hardness consists of non-carbonate based metal salts, and does not
    precipitate out on heating.

  • Will hardness affect the performance of an Ultracarb filter element?

    The ATS media used in our Ultracarb filters will adsorb lead, even in the presence of calcium and magnesium ions. This is proven in the NSF certification testing. One of the test protocols for metal(s) reduction calls for testing at high pH, high TDS conditions to simulate use in hard waters. Filter elements containing ATS have to pass this part of the test protocol before they can receive NSF certification.

  • Will my Doulton or British Berkefeld filter element remove Aluminium?

    The Doulton and British Berkefeld range of ceramic water filters are only suitable for the removal of aluminium in particulate form; they are not proven to be suitable for treating dissolved aluminium. To treat water containing soluble aluminium, ion exchange resin, distillation or reverse osmosis must be used.

    passage through activated alumina is the best method.

  • Will my Doulton or British Berkefeld filter element remove all types of bacteria?

    No, there are so many different species of bacteria of different shape, size and growth characteristics, which preclude the ceramic filter from being effective against all of them. The pathogenic bacteria that
    FICL claim to be effective against have been qualified by test data from independent test laboratories or are extrapolated from test data, of similar microorganisms (please seek advice on permitted
    extrapolated claims).
    Also although the ceramic will filter all types of heterotrophic bacteria to some extent, it should be noted that any harmless bacteria of this type passing through the ceramic may multiply downstream of the filter. Since these heterotrophic bacteria are harmless, normally there are no problems and some heterotrophic bacteria are reported to be beneficial (see the section on Heterotrophic Bacteria pg 19).
    However, if normal use of the filter is interrupted by holidays or vacations, growth of these bacteria may result in a ‘flat' or ‘stale' taste for a period of time when use of the filter resumes. This is especially true for the filter elements that contain activated carbon such as the Super Sterasyl (contains granular activated carbon), the Supercarb and Ultracarb (both contain an extruded activated carbon core). Any system containing activated carbon, which will reduce residual levels of free chlorine, will result in an increase in plate counts over a short period of time until a constant state of equilibrium is established. The UK Drinking Water Inspectorate water regulations call for the water to be regularly monitored for
    consistency as used, therefore since an equilibrium point is reached in the filtered water, the filters comply with the regulations. The presence of this type heterotrophic bacteria does not constitute a health problem since the organisms present will be harmless and a suitable level of consistency would be established. Flushing the filter system for several minutes after any prolonged period of inactivity should eliminate the problem.

  • Will my Doulton or British Berkefeld remove diesel, petroleum or MTBE?

    The ceramic part of our filter elements will not take out any of these organic materials. The activated carbon in the Supercarb and Ultracarb filter elements will have some effect, however, to remove these type of materials requires much greater quantities of activated carbon and much longer contact time than our filters can provide.

  • Will my Doulton or British Berkefeld filter element remove Iron?

    The Doulton and British Berkefeld range of ceramic water filters are only suitable for the removal of iron in particulate form; they are not proven as suitable for treating dissolved iron. To treat water containing soluble iron, the iron must be oxidised to induce precipitation prior to filtration. Alternatively distillation or reverse osmosis can be used.

  • Will my Doulton or British Berkefeld filter element remove Legionella?

    Since Legionella has a similar morphology to E-coli our ceramic filter elements should provide similar protection against Legionella. However, Legionella is capable of slow regrowth downstream of the
    filter, so if just one organism passes through the ceramic it could eventually colonise the water delivery system. Therefore it is important to regularly disinfect downstream of the filter or fit a UV light just after the filter.

  • Will my Doulton or British Berkefeld filter element remove Oestrogen and Synthetic Oestrogen?

    There has been a limited amount of research into Oestrogen and Synthetic Oestrogen, and so we do not have quantifiable test data on the effectiveness of our products in removing it. Due to the chemical
    properties of Oestrogen, we believe that activated carbon would be effective in reducing it. However until better test methodology is available, we are unable make a claim.

  • Will my Doulton or British Berkefeld filter element remove Pseudamonas aeroginosa?

    Pseudomonas aeroginosa is a potential coloniser of water system networks and is similar in size to E-coli. FICL candles should therefore, in theory, show a similar reduction efficiency for Pseudomonas aeroginosa as E-coli 4.
    However, since this organism is rapid growing and may recover quickly. Without physically testing FICL ceramic filters with this type of organism, it is impossible to predict a performance claim.
    FICL are not prepared to attempt a prediction of performance, since the filters do not provide 100% barrier to E-coli, a limited number of cells may pass through the filter which, unlike E-coli may form colonies down stream of the filter. It would be more suitable to combine filtration with a disinfection stage to ensure removal of Pseudomonas aeroginosa.

  • Why does the pH of my drinking water increase when I use my ceramic filter?

    The slight increase in the pH of water passed through the ceramic filters is due to the presence of the mineral Wollastonite in the ceramic filter. Wollastonite is slightly soluble and alkaline, so may
    partly dissolve in the water as it passes through the filter causing a minor pH shift which is harmless. No health based guideline value for pH in drinking water has been proposed by the WHO, although accompanying notes to the guidelines state that the pH range is often in the range of 6.5-9.5. In general there is little evidence to suggest that pH in potable water of around 9-10 is of public health significance.

  • What level of bacterial contamination can the ceramic cope with before I need to use something else?

    In the absence of conclusive data regarding the levels of infective doses for specific pathogens, the FICL microbiological laboratory has been testing our filter elements for many years using an influent challenge of 6 log of E-Coli to substantiate the 4 log E-coli reduction claim that we make. This level of protection offered by the filters is more than adequate in all protected waters and the vast majority of moderately contaminated surface waters. However if the level of contamination in the water exceeds levels of 104 (4log) an additional
    treatment must be used such as disinfection or UV light treatment. It would be extremely unusual for water having a greater level of contamination than 104, to be considered suitable as a potable water source.
