Product Description
Flat sheet membrane filtration which we mean RO membrane flat sheet and NF membrane flat sheet. And our RO membrane flat sheet mainly exports SWRO as normal, only because standard RO flat sheet is very complex and quality is in different level, and sometimes customers pursue of price but not keep quality in first, but with conflict even we confirmed in first.
Puri-guard, for membrane flat sheet, we only keep in highest level and provide based on sincerity and honesty, as flat sheet is the key part of membrane elements.
For the flat sheet membrane nanofiltration mainly focus on NF30, NF60 and NF90:

Based on its specific membrane flat sheet technology formula and configuration, the color will be a little different on different type of membrane flat sheet.
Performance of membrane flat sheet based on the above and on each of contract, will mark clearly on contract.
Package of membrane flat sheet, based on long-term and far away sea or air shipping, we use strong carton and roll normally on 500sqm/roll around.
Once you get the membrane flat sheet, should store in dry and no-sunlight direct places, humidity between 30%-70%, control temperature range from 5-35°C; Try to use it earlier within three months after shipping from Chinese port.
