ACTIVATED CARBON AND BIOFILTRATION TO REMOVE DPBs. Probably combined with RO, this is a good start. http://lnkd.in/dcEGbiB View in LinkedIn

DPB REMOVAL. "Biologically active filters resulted in removing some DOC (25%), DON (18%) and—to a lesser extent—UVA (12%). Removal of THM precursors through the filtration process was low (3%), while the removal of precursors (relative to what was found by DBPFP testing of ozonated water) for trihaloacetaldehydes, chloropicrin and NDMA was high (55, 75 and 67%, respectively)." http://rsta.royalsocietypublishing.org/content/367/1904/4077.full View in LinkedIn

DBP IN WATER. A useful reminder of the issues at hand when considering methods to remove these carcinogens as they enter your home. http://water.epa.gov/drink/contaminants/basicinformation/disinfectionbyproducts.cfm View in LinkedIn

REMOVAL OF CHLORINATION BYPRODUCTS. "Various methods ... include adsorption on activated carbons, coagulation with polymer, alum, lime or iron, sulfates, ion exchange and membrane process for the removal of DBPs." http://lnkd.in/dmThrs7 View in LinkedIn

STUCK ON OLD TECHNOLOGY. "Since the 1970s, the water treatment industry stood still, while the technology industry made incredible progress. What would Steve Jobs or other technology innovators do with the POE/ POU water treatment industry?" http://www.watertechonline.com/articles/166470-infusing-technology-into-the-drinking-water-industrys-future View in LinkedIn

CHLORAMINE REMOVAL. Read this compelling summary about the problems with chloramine but disregard the sticker shock quote about prices, which is wrong. You will need activated carbon at source and reverse osmosis at cooking taps. http://www.chloramine.org/chloraminefacts.htm View in LinkedIn

POINT OF ENTRY (POE) DEVICES. http://lnkd.in/dZ3Rwb3 View in LinkedIn

"CHARCOAL FILTERS have an annual estimated cost of US$10 to 100 for a family that uses 25 liters of water per day. Countries with local access to charcoal, or materials ... will face significantly lower costs that those that have to import the charcoal filters. Activated carbon filtration systems have an estimated average annual cost of over US$100 for a family that uses 25 liters a day." http://lnkd.in/dna7M4i View in LinkedIn

US POU ADVISORY. "No single treatment process can remove all substances in water. Select a treatment unit designed to handle the substance of concern. If there are several substances you want removed from your water, you may need to combine several treatment processes into one system." http://www.health.state.mn.us/divs/eh/water/factsheet/com/pou.html View in LinkedIn
