Backflow protection is provided by BestElements Directflow reverse osmosis filter systems WA3, WA7, and WA9.<\/p>\n
The risk of backflow generally only exists with filter systems featuring an outdated design with a storage tank and permeate pump in multi-stage filters.<\/p>\n
BestElements Directflow systems operate without a tank and meet the requirements of DIN EN 1717 Category 2, thus preventing backflow under normal operating conditions.<\/p>\n
The ultrapure water section is protected by multiple check valves.<\/p>\n
The ultrapure water section is permanently pressurized.<\/p>\n
The wastewater section is protected by multiple check valves.<\/p>\n
For purely physical reasons, wastewater cannot enter the ultrapure water system.<\/p>\n
Optional:<\/p>\n
A hollow fiber membrane can be installed for critical locations.<\/p>\n
A separate outlet can be installed for critical wastewater situations.<\/p>\n
