RO Membrane Cleaning Best Practices
Q: We are cleaning heavy scale compounds of Ca, Mg, carbonates, phosphates and organic matter from reverse osmosis (RO) membranes. Can you tell us some cleaning best practices and recommend a detergent?
A. If the organic matter is significant, a two-step process, cleaning by re-circulation or soaking (re-circulation may be more effective) could be needed. If the organic matter is biologic in nature, we would recommend Tergazyme® Enzyme-Active Powdered Detergent which is both a powerful emulsifier along with protein enzymes. If the organic residue is more of an oily nature…
Neutralizing Citranox for Waste Disposal
Q. We manufacture electronics and use Citranox to cleans oil off of a variety of machined parts. However, our Municipal Water District does not allow the disposal of spent Citranox. Can you recommend a neutralization procedure?
A. You will need 0.14 lbs, 0r 2 ¼ oz of baking soda (sodium bicarbonate) to neutralize a gallon of un-used 1% Citranox solution to a pH near 7. Note that some of the acidity in Citranox may be depleted …
No Liquinox Algae Bloom
Q: Will Liquinox cause algae bloom? A: No. Liquinox will not cause algae bloom. Here’s why. There are several important factors concerning discharge of spent cleaning solutions into the environment: biodegradability, aquatic toxicity and eutrophication acceleration. Algae blooms relate specifically to eutrophication.
The primary source of eutrophication is…
Nutrient Solution Contamination
High concentrations of bleach and H2O2 are breaking down PVC pipe and plastic containers causing contamination of a nutrient solution. I need a cleaner that breaks down biofilm and a cleaner that cleans nutrient salts. I can sterilize with H2O2 using a much lower concentration at the end of process.
Pharmaceutical Cleaning: Probiotics
Q: Can you tell me if Liquinox can clean/remove pharmaceutical probiotics? We use this product to clean our packaging lines. We have a customer who is looking to have us package their probiotic product.
A: Liquinox® Critical Cleaning Liquid Detergent is an excellent emulsifier of organic and oily residues. It will do the job. Best practice, however, would be to incorporate a powerful emulsifier of organic and oily residues, along with enhanced protein removal.
