Good day.....I am in the final stages of prep before installing the equipment absolutely required for my residential well water H2o2 injection system. My purpose for H2o2 use, remove 1.8ppm iron, live iron bacteria and occasionally a whiff of H2S (appears to be seasonal in my case).... Note* chlorine is not an option due to medical issues... I have been getting conflicting information concerning the "necessary equipment" absolutely needed for a properly functioning system with respect to both iron issues.
I have spoken to several (4) local {"water professionals"} here in Florida and a couple (2) from out of state regarding H202 injection systems for my purpose; their suggestions have put me in a practical dilemma...
The conflicting issue? The use or required need of a retention tank for contact time.
Option #1 32% solution with sediment filter and no contact tank needed due to strength of solution.
Option #2 7% solution no sediment filter and a contact tank is mandatory due to weaker solution strength.
4 of the 6 {WP} contacts recommended Option #1 unequivocally with a 1 or 2 ppg water meter in lieu of flow switch for precision injection control , 1 of the 4 mentioned an inline static mixer was used in the past but has now fallen out of favor.
The remaining 2 {WP} contacts "pushed' Option #2 with a flow switch in lieu of water meter, citing the solution safety as the primary concern and a more forgiving parameter when dosing with the weaker solution.
In a previous life I spent many years working in chemical / industrial / food plants with and around caustic chemicals and oxidizers; I am keenly aware of the precautions needed in handling 35% H2o2, Ain't skeered (lol)
From the limited information gleaned from the web, both options will work... The Stenner pump, PCM, 1ppg water meter and a GAC backwash filter on site and ready....
Retention tank or not????????
Appreciate your real world opinions; facts are even better!!!!
