These media can be mixed in a multi-layer bedwhich, when combined with an appropriate backwash or regeneration SYSTEM , can betailored to solve a wide range of specific contaminant and manganese and sometimes aluminium and hydrogen sulphide can beremoved with a catalytic FILTER media, which uses oxygen in the water to convert themetal ions from the soluble to an insoluble form.

6 The insoluble precipitate is thenfiltered out onto the surface of the media. Depending on the composition of the rawwater a choice of media can be FILTER media is one of these medias and just requires backwashing with theraw water to clear the bed. The operating parameters for PYROLOX make it suitable fora number of water . 2S y s t e m M a n a g e m e n tIn order to remove accumulated deposits from the FILTER bed, the water flow throughthe FILTER is reversed (backwashed). Water is run to drain at a high rate to separatethe FILTER media from the deposits. The control valve completes the backwashcycle automatically at the intervals and times set during installation.

7 Backwash and fastrinse times are set for 16 minutes per cycle but can be altered to suit FILTER valves have the option of an additional volt free microswitch, which can beused to initiate a regen pump FILTER SYSTEMINSTALLATION OPERATION MAINTENANCE MANUALPYROLOX WS ISS 1 \page53 . 3P y r o l o x S y s t e m O p e r a t i o n ' F r e q u e n t l y A s k e dQ u e s t i o n s 'The main uses for a PYROLOX FILTER are for domestic and commercialremoval of Iron, Manganese, Hydrogen Sulphide and general turbidity. ThePyrolox media is a catalytic media that is not used up in the reaction howeveroxygen has to be present in the water to enable the oxidisation to occur.

8 If thefeed water does not contain the necessary level of oxygen then a SYSTEM foradding this will be requiredThe feed water flows under pressure to the control valve on the vessel whereit is directed through to the filtration media. PYROLOX systems built with WS1, or 2 valves will bypass raw water during backwash. For this reason thesystems are set to backwash at 2:00 Iron levels: PYROLOX systems can be used on Iron levels ofup to 20 ppm with certain reservations. There are a number ofexamples working satisfactory at higher a n g a n e s e r e m o v a l :Ma n g a n e s e r e m o v a l in a P yr o lo x s ys t e m isdependent on the level of Iron and other contaminants in the raw water.

9 Thegreater the amount of Iron, the easier it is to remove the Manganese. Withan Iron: Manganese ratio of 10:1, the Manganese is extracted very well at apH of When the ratio reaches 5:1 then the pH needs to be When the Manganese level exceeds the amount of Iron then a pH ofabove is required. While the pH correction media in the PYROLOX blendwill raise the pH of acid water, it cannot raise it above consistently if thegeneral level of dissolved solids is high and the Langellier index is full water analysis is essential when considering using the PYROLOX systemprimarily for Manganese Sulphide:Hydrogensulphideisremovedatconc entrations of up to 3 acid/tannins:Decaying organic matter in the raw water supplycreates Humic acid or tannins, sometimes seen as light brown colour in lowpH 'peaty' water supplies.

10 These tannins can combine and complex with Ironand Sulphur, coating and blinding the media reducing its effectiveness. Thetannin level in the raw water should be less than 2 ppm and ideally lessthan 1 ppm to eliminate the need for frequent changes or rejuvenation of thefilter media. With high tannin water supplies it will be necessary to oxidise thetannins to an insoluble floc that is filtered out with the other most effective oxidiser is Ozone, and an Ozone generator with injectionventuri and off-gas valve has proved to be very successful at preventingtannin blinding. An alternative is to remove the tannins with an OrganicScavenger.
