We are building a new unit, and are considering putting in a bicarb loop. This is not currently being done in my area, and I would like to know what is being used for disinfectant, how often it is done, and what problems have been encountered. Any info is appreciated, Thanks.

yes do it i like mine a lot----we bleach daily 1:100 mix there are fmc units that use ozone --takes about 30 minutes to clean in 2 years i replaced 1 pump cost $120.00 and took about 1 hour easy system to clean and trouble shoot let me how it goes

Yes I agree with the previous statement. You must disinfect daily with a 1:100 bleach solution. Bicarb loops are extremely efficient and alleviate quite a bit of work on the staff but must be paid constant attention. I recommend that you consider an acetic acid flush of the loop once a week as well, to eliminate bicarb deposits that could potentially clog the loop. Also I would definetely encourage testing the specifig density of mixed bicarb before sending it through the loop (this will save a lot of time if its not mixed properly). Specific density barometers can be purchased through HACH and you can contact your concentrate manufacture for specific ranges. Hope that helps.

Bicarb loops are great in a dialysis centers because they alleviate a lot of work for the
staff but they are also a huge resposabilty. The loop must be cultured routinely to avoid any incidents. Disinection of the loop routinely is also a must!I like using bleach myself for disinfection it seems
to the job very well.Good luck!

Bicarb loops are just one more place for a potential problem to happen. I agree they do work, but do require close monitoring. Some units have problems monitoring what is happening in there own R/O / DI systems.
