Benefits of PP membrane in comparison with PES
•Lower adsorption tendency of wine ingredients – gentler filtration•Symmetrical pores – higher cleaning efficiency•Greater resistance to proteins and abrasion•Longer membrane lifespan•100% alcohol resistance

Backwashing & Reverse flow

System diagram

System workflow:
•feeding - feed pump•concentrate – 2 way flow in the loop – low speed circulation pump• backwash – buffer tank with rubber bag
Gentle and efficient filtration
Reverse flow benefits
Dokonalá filtrace www.filtrace.com
Gentle and efficient filtration
Membrane clogging - backwash
Conventional system - one-way flow
The circulation of the tangential flow in one direction only leads to an uneven surface membrane filter clogging, reduced efficiency of backwash and therefore less filtration throughput.

Gentle and efficient filtration
With the automatic rotation of the tangential flow direction is used by more equitably the entire filter surface. Therefore backwash cycles are more efficient and cleaner membrane.
