No offense....I actually just gave this question to one of my techs to research and gave him till Monday morning to answer.
I'm hoping he reads the entire chapter on carbon in the NANT water book and aBsorbs (not aDsorbs) the information.
I don't want this to be too easy for him (sorry J.C.) so PLEASE...don't answer this question here until after Monday morning.

also ask him about what type of carbon is in the filter for TOC We actually went over this yesterday. Myself and another of my techs have brain-farts with this sometimes. We only have an Organic Scavenger at one facility. We initially had an ion-exchange scavenger but when the resin degraded, we found that it was on backorder and wasn't expected in for 3 months. It was then that we switched to carbon (lignite). |

Of the 4 most common GAC's, lignite has the highest molasses number at >300. |

8x30 is fine if you have a lot of dirty water in your area and you are using portable equipment where backwashing isn't regular. Typically for incenter pretreatment systems you would use 12x40. Higher rate of clogging but regular backwashing handles that.

Based on my answer above....What do you think? I’m not sure why Chuck can’t just answer: No. Because I already answered his question. He didn't like the answer so he was trying to get a different one. |
