from own wells, cisterns and ponds
your home is connected to municipal water supply, you may be relatively
certain, at least within the EU, that the water quality is within the
limits of the respective drinking water ordinance. In general, the
drinking water suppliers treat their water using modern and complex
techniques before supplying it to their customers. If you use your own
water well and/or cistern, you should make sure out of self-interest
that you do not catch any infections from your water supply. The times
when water from wells, cisterns and lakes was harmless are definitely
over, a fact that also constitutes a global problem. As an example, you

the advantage of the most beautiful holiday home when there's only
dirty, brown water coming from the tap?
of serving clean, odour-free and tasty water, your tap delivers a muddy
blob, sometimes smelling like rotten eggs, with a metallic, moldy
taste. Your formerly shining-white basin, the bathroom tiles and the
shower base show ugly brown stripes and stains which can't be scrubbed
away by any means. And the water outlet of the tap is edged with
water in your swimming pool that also came from your well is getting
more and more turbid, although you installed a sand filter and added
chlorine, and a greasy brown covering is developing at the bottom of
These situations portrayed above, you can perceive directly by the
senses of sight, taste, smell and touch. An invisible thread, however,
especially in cases of elevated iron contents, emerges from
ferro-oxidizing bacteria within the piping system. While
ferro-oxidizing bacteria within drinkin water pipelines (technical
term: iron ochre) are relatively harmless to humans, they still
constitute a basis for biofilms, on which coliform bacteria

contents in well water:
Iron is the fourth most abundant element in the earth’s
and is solved from the bedrock by the rainwater seeping down towards
the water-bearing layers. Elevated iron contents often are not
immediately visible in the tap water; the clear well water only turns
yellow or brown in the sink through the absorption of atmospheric
The removal of iron contents from the well water is possible only with
special oxidizing filter materials which convert the bivalent iron
dissolved in the well water into iron[III]-oxide compounds and filter
factor hydrogen sulfide:
Since iron ores are generally contaminated with sulfur, and the seeping
rain water carries relatively high contents of carbon dioxide, often
hydrogen sulfide gas develops, emitting the unpleasant smell of rotten
eggs. However, there is no acute health hazard.
factor iron bacteria:
Iron bacteria serve as a breeding base and thus promote symbiotic
communities with bacteria, fungi and other microorganisms (biofilms)
which can be found at all boundaries between solid surfaces and aqueous
solutions. Therefore it is appropriate, especially for pre-contaminated
drinking water pipelines, to clear the well water of the iron contents

is a highly porous permanent filter granulate with an active
AOP-coating, which acts oxidizing and catalytic with all substances
entrained in the water.
AOP means that even solutes such as the heavy metals lead, copper and
zinc, as well as iron, manganese, arsenic, etc. are converted into
solids. In addition, all microorganisms such as bacteria, algae and
fungi, are eliminated by the strong oxidizing effect of the surface
coating. With a filtration fineness of 2-3 microns (compared to about
50 microns with filter sand), these impurities are filtered as well as
all other suspended matter, and very high filtration rates of 95-99%
are achieved over the entire pH range.
The oxidizing effect of the material is refreshed in each backwashing
by adding PROTABS OXY in the rinse water, thus remaining unspoiled
throughout the whole service life of the filter granulate.
release so-called Hydroxyl Radicals (OH-groups), whose strongly
oxidizing effect eliminates all sorts of bacteria, legionella, algae,
amoeba, fungi, protozoa and other microorganisms. PROTABS OXY with
their high oxidation potential of 2.8V have a much stronger effect than
most common biocides such as chlorine (1.4V), chlorine dioxide (1.5V)
hydrogen peroxide (1.8V) and even ozone (2.1V). Other than almost every
other biocide, PROTABS OXY leave no disinfection by-products (DBP), and
have much lower corrosive side-effects on metals, plastics and sealings.
PROTABS OXY are not subject to specific labelling obligations, neutral
in handling and non-toxic!
