Happy World Water Day 2017!!!
March 22, 2017We helped a concerned home owner today with her filtration system she uses to filter her City of Flint water. She is concerned about volatile organic compounds (VOCs), including those created in the chlorination processing of the water (trihalomethanes for instance) and would also like to reduce sediment, heavy metals, and potentially bacteria in the water.
She only has a two stage filtration system, limiting the options, so we eliminated the 20 micron granular activated carbon (GAC) filter she had been using as a pre-filter and made the primary 0.5 micron (bonded) powdered activated carbon (PAC) filter the pre-filter, and adding a ultrafiltration (UF) filter as the primary filter. The PAC filter is treated with a specially designed adsorbent medium for lead and mercury reduction, and the UF filter (removes particles down to 0.01 microns) will filter out bacteria and other pathogens. We also packed the filter vessels with activated alumina beads to increase the heavy metal and fluorine removal capability of the filter system. We’ll keep in touch and see how the system performs.
