Sand/Pyrolusite filtration
Sand/Pyrolusite filtration
(OP)
I'm suppling filter which have as media a mix of quartz sand and pyrolusite. The pyrolusite supplier says that pyrolusite and sand will remain well mixed during backwashing because they have similar specific weight and granulometry. But I understood that pyrolusite worn out. Do pyrolusite reduce his granulometry? And what happen in this case? Will pyrolusite form a layer diveded from sand? I have to replace the media or can I add pyrolusite? And how can I mix the added pyrolusite with the rest of the media?
Thank you!
Thank you!





RE: Sand/Pyrolusite filtration
If the pyrolusite is lost, you should be able to add additional media on the filter prior to a backwash. When backwashed, it should settle into its respective zone. The same can be said for adding sand or anthracite to a dual media filter.
