Water treatment plan
Current water treatment unsatisfactory. Existing is acid neutralizer tank followed by waterconditioner using resup for iron followed by whole house carbon filter.
Water test from lab (all equipment in bypass mode and flushed for 5 min before draw):
E Coli & Coliform: none detected
pH: 7.35 mailed in sample
TDS 203 mg/l
Hardness as CaCO3: 129 mg/l (8gpg)
Corrosivity Index @ 25 deg C: -.57(fail)
Fe: 2.43 mg/l (FAIL)
Mn: .22mg/l (Fail)
Ca: 39.1 mg/l
Total Alkalinity 64 mg CaCO3/l
Radon: 530 pCi/l (FAIL)
(Also some Hydrogen sufide smell in water)
7.5gpm flowrate @ pressure tank
immediate onsite acid test showed 7.0 (Milwaukee test meter)
Puzzled by ph readings since at initial house purchase, water failed as too acidic(after treatment equipment read 6.39).
Proposed remedy: Manganese oxide (Filox) iron filter preceded by aerator with ozone injection(small spa type chip based unit JED203). Ozone injection would keep aeration tank sterile for lower maintenance and prevent further intrusion of iron/sulfur bacteria. Aerator should increase PH slightly by reducing carbon dioxide, vent Radon and start oxidation iron, manganese and Hydrogen sulfide(if any at wellhead). I would prefer some minerals in drinking water so would eliminate the water softener. This layout is more expensive and probably overkill, but I would like to reduce maintenance, lugging salt and have better tasting water without iron staining.
Is this plan sound? Is a $2,000 aerator tank going to be good enough quality to last? Does an aerator tank preserve the flowrate(gpm) available for backwash purposes. It has its own pump and pressure tank.
