The chemists and engineers at Blue Earth Products can analyze your filter media, determining the type of deposits and the extent of deposition. Blue Earth Products understands this chemistry and developed the complete line of patent pending formulas to address these varying requirements. Remove these deposits to restore your filter media to its design conditionsīlue Earth Products designed its suite of filter cleaning products specifically to dissolve these deposits, so that they can be rinsed away.ĭue to the wide variety of filter media, deposits, and filter construction, media cleaning chemistry also varies. This rounding is the most frequently cited reason for media replacement. Rounds the angularity of the particles, impacting their ability to create the turbulent flow needed for optimum filter performance.Reduce the uniformity of the media particles, altering the fluid flow patterns and contributing to channeling and short-circuiting.Increase the size of the media particles, filling voids, degrading the capacity and altering filtration properties, reducing effectiveness.These deposits alter the media characteristics: However, over time, organic and inorganic deposits – biofilms, calcium scale, iron, manganese, algae – coat the media and can’t be removed during the backwash. Usually, there is nothing wrong with your media. You just hope that this whole process doesn’t damage your underdrains. With water demand up, you just don’t know when you will find the right time. You contact the landfill to determine the disposal fees. Then you start making calls to the media suppliers to determine the replacement costs. The disruption, as you vacuum out the filter media, try to clean the filter walls, troughs, and underdrains, and then truck in the replacement media, will take well over a week. You also know it needs to be an extended period as this is affecting ALL your filters, not just one or two. Grudgingly you look at the calendar and demand records for the last year, hoping to find the next low demand period so you can take the filters out of service and replace the media. It’s not what your customers have come to expect. The water quality is still acceptable, but not where YOU want it. Your turbidity numbers are higher than you like to see them. Even immediately after backwashing, headloss remains high and the filter capacity is not what it needs to be. Backwashing seems uneven, and doesn’t seem to be getting the filters clean. Filter runs are getting shorter and shorter.
