I've attached a recent KAR - 90 water report for the water I would like to treat.
Description of Application:
This well supplies a small winery facility with water usage of 500 gallons per day with very occasional 1,000 gallon days and often no water used for 2 weeks. Iron bacteria is present and it is my main concern. There is also a small amount of iron, manganese and H2S present.
Goals:
1. Keep iron bacteria from sliming up my pipes and causing water to stink.
2. Remove iron
3. Removal of hardness would be nice but not nearly as important as 1 and 2.
Current water distribution system:
There is a 12 gpm submersible pumping from the well directly to a 3,000 gallon storage tank (no pressure tank in this system, just a float switch). Water is pumped to the winery by a 20 gpm submersible located in the storage tank which is powered by a variable speed controller Aquavar Solo 3AS20.
My current water treatment equipment:
H202 proportional Stenner injection panel (flow meter, spin down filter, peristaltic pump and pump controller), 16x65 backwash filter loaded with zeolite controlled by Fleck 7000SXT. Originally I used the H202 the backwash filter loaded with 4 cuft of catalytic carbon. The water quality was pretty good at first but eventually the pipes loaded up with bacteria and began to create H2S issues. Iron dropped from 0.20 ppm to 0.02 ppm while I was using the h202/catalytic carbon treatment.
I can't used chlorine to fix the iron bacteria problem unless there is a reliable and economical way to reduce free chlorine down to 0.00 ppb since i'm using this water in a winery (chlorine can cause serious contamination issues when mixed with a certain molds which can create a compound called Trichloroanisole)
The local water treatment company recommends that I install:
a pressure tank on the well pump--> Next Sand backwash filter (with a No Hard Water Bypass controller)---> a twin alternating, non electric kinetco water softener ---> a solenoid valve which controls the inflow of water to the storage tank(which is controlled by a float switch). They also recommend installing a UV system between the storage tank and winery. $7k installed (includes backwash, softener and UV only)
My latest best idea on system design:
-10" (1.5cuft) Katalox light backwash filter with No Hard Water Bypass (what would you recommend for a valve?) with service water flow restricted to 5gpm and backwash restricted to 6 gpm
-24,000 grain dual softener with Fleck 9100 SXT flow restricted to 5 gpm
-solenoid valve controlled by float switch in the 3k gal storage tank
-no UV at first and see if I have bacterial issues without the iron
Can you offer any additions or modifications?
Would you recommend standard 8% softener media resin?
Thank you.
