Now that we all know what biofilms are (find out about biofilms in our companion article), let’s speak about HOW to take away them and forestall their return. Please keep in mind that these strategies and merchandise don’t KILL the biofilm and no assertion is made to that impact.
Biofilms might be eliminated mechanically, chemically or “naturally.” Mechanical elimination makes use of hand or computerized vacuums, wall brushes, scrub brushes, filter cleaners, etcetera, bodily take away the biofilm from seen locations.
Seen locations can be the filter cartridge itself, filter tank, vinyl liner, water line, ladder treads, skimmer baskets, and so forth. You may bodily deal with the article that must be cleaned. This is likely one of the the reason why we as Pool Professionals are so adamant about brushing the pool’s surfaces on a daily, weekly foundation. Brushing breaks up and lifts the biofilm off from its cozy environs enabling the chlorine or different sanitizer a greater alternative to kill it and the filter to take away it. Watch out nevertheless to commonly clear & chemically clear the filter to take away the accumulations of “filtered” biofilms from the filter media – whether or not it’s sand, DE or cartridge.
Take into account that biofilms are a direct contributor to chlorine demand, inflicting the pool to make use of considerably extra chlorine, bromine or biguanides than if none had been current. Take away the biofilm, take away an vital part to chlorine demand.
In exhausting to achieve locations like pool plumbing strains & inside heaters, biofilms should be eliminated Chemically. That is the place a lot biofilm (and about 99% of the micro organism) accumulates and thrives. Biofilm is left alone. It has all that it wants – a floor, moisture, and vitamins floating by. Take into account that biofilm would not want daylight – it isn’t an algae so daylight is just not one among biofilm’s wants. Biofilm does want “heat” water – 90 F or higher for optimum progress, however so long as it isn’t chilly, the biofilm will survive and develop simply tremendous thanks.
Tried & true merchandise corresponding to pure enzymes (Pure Chemistry® Pool Good, Pool First Assist, and so forth.) “eat up” a lot of the vitamins and different waste that contribute to biofilm progress thereby stunting it. However as biofilms change into extra resistant and extra proliferate, a brand new arsenal of merchandise should be thought of & used. Newer merchandise corresponding to AquaFinesse(TM) Pool Pucks are added to the pool skimmer and fairly quickly take away the biofilm from the hidden surfaces. AquaFinesse(TM) merchandise have been efficiently used within the European market and in industrial purposes for a number of years. As with the bodily elimination merchandise, loosened & eliminated biofilm particles should be filtered out of the water after which faraway from the system solely. After preliminary software, you’ll discover that the filter turns into quickly clogged because the filter traps all of that used biofilm. Cartridge and diatomaceous earth filters should be chemically cleaned to revive the filter to a correct working situation. If biofilm elimination has by no means been completed earlier than, it might be essential and even advantageous to switch the filter media – particularly in older swimming swimming pools. These merchandise are utterly appropriate with all pool care chemical techniques (chlorine, bromine, biguanides, ionizers. salt).
An excellent newer, “gentler” pure approach to take away biofilm is utilizing sphagnum moss. In testing by Montana State Univ. Heart for Biofilm Engineering, sphagnum moss was discovered to be a wonderful preventive and remover of biofilm. It was seen in lots of ponds and lakes the world over that the place sphagnum moss lived and thrived, water high quality of these lakes and ponds was “potable” or drinkable with out the necessity for filtering or chemical sanitizing. New patented merchandise such because the patented PoolNaturally(TM) and SpaNaturally(TM) use eco-friendly, eco-processed sphagnum moss in disposable, shopper pleasant pouches to take away biofilms and forestall biofilms. Research are additional exhibiting that pool water handled with sphagnum moss stays higher balanced (pure buffers are current within the moss) and is “gentler” for swimmers. PoolNaturally(TM) sphagnum moss pouches are changed on a month-to-month foundation for optimum impact. Sphagnum moss merchandise work with all chlorine, bromine, salt techniques, and ionizers however are NOT appropriate with biguanide merchandise corresponding to BioGuard® Comfortable Swim® or Arch Chemical substances® Baquacil®.
The underside line for the pool proprietor and buyer is an extended lifetime of the pool and pool tools (filter, heater, rails, ladders, and so forth.) as a result of elimination of biofilms in addition to biofilm scaling. Chemical consumption ought to and can present a marked lower as chlorine, bromine & different sanitizers can consider the 1% of “planktonic” (free floating) micro organism current within the water. Simpler water stability, much less stunning, and so forth. Bear in mind to proceed a daily water testing and chemical upkeep routine – adjusting pH, whole alkalinity, calcium hardness as essential. Regular stunning oxidizes bather and environmental waste (chicken droppings, human sweat).
It’s true that solely time will show the efficacy & effectivity of those new remedies, however the research to this point look extraordinarily promising.
