WHERE OUR JOURNEY BEGAN
Bain Kibler of Kibler Water Softeners spoke at a Maintenance
Summit attended by our Maintenance Supervisor, Bill Mentele
• He spoke about the systems he has, in addition to maximizing the systems
• When Bill returned to the facility he realized we had not been maximizing our system’s efficiency so he contacted Bain directly and
worked with him to get better results
-
HOW OUR SYSTEM WAS RUNNING
• Our Water System is a Kibler ASDC-4284-3/1.5.5/SS
• It has a 1.2 million grain capacity
• We had it set to 999,000 grains
• The Water coming into our facility • Our average water consumption is about 57,650
gallons per day
• Has a hardness level variance that can change daily
• We had the Water Softener set to one specific point (for example set for 24 grains)
-
RESULTS OF OUR CURRENT CONFIGURATION
• Regeneration too soon
• We were not efficiently using the system to capacity
• The calculation for regeneration was not accurate because the grains in the water changed daily
• Either ended up with hard water
• Or short cycle the system and using more salt than needed (sending it out to waste water)
-
NEW PROCESS TO MAXIMIZE SYSTEM
• Adjusted to actually hit the total system capacity (999,000 to 1,200,000 grains)
• Physically measured the resin beds in the water softener to ensure the calculation for capacity was accurate (softening
capability = 20,000 grains/cubic feet of resin)
• Check incoming water for hardness levels daily
• Adjust the controls accordingly
• When the hardness level is 24 grains we can only soften 41,625 gallons per regeneration
-
NEXT STEPS TO TAKE…
• Ensure our regeneration process is efficient and maximized
• Either on the Incoming Side
• Calculate the amount of salt needed to saturate the resin and put a flow meter on the incoming brine side
• Or the Outgoing side
• Put a conductivity meter on the drain to ensure we don’t over brine the resin beds & ensure we are not sending too much salt down the drain
• Continue to have our resin tested ever 2 years (Kibler does this for us)
• To ensure it has not broken down
