CROSS-FLOW filtration principles

Feed wine

Concentrate

Filtrate


Application




Common application

Mustmechanical and microbial filtration before fermentation as de-sludge or final filtration of finished product instead of pasteurization



Common application

Wine wines at various stages of production



Common application

Champagne champagne and sparkling wines produced under pressure



Common application

Stop fermentationstopping primary and secondary fermentation of must and young wine at the required volume of alcohol



Common application

Wine spoilagepreventive and corrective microbial filtration in the case of wine spoilage and faults such as yest Bailii, Brettanomyces, Acetobacter bacteries etc


FCW concept



FCW – Filter Crossflow for Wine

1. Strong emphasis on gentle wine treatment

2. Process efficiency and economy

3. Customer care


FCW concept


The main FCW benefits




• Reverse flow

• Up to 40% energy savings due to serial arrangement of modules

• Bakwash with filtrate

• Polypropylen membrane

• Minimum room requirements




Stainless steel modules provide sparkling wine filtration

Polypropylen membrane


Filtration membrane


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


Reverse flow benefits



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.

backwash of the membrane the membrane after backwash



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.

Membrane clogging - backwash


Reverse flow benefits:

• much higher filtration surface efficiency

• more effective cleaning

• higher capacity of filtration cycle

• higher filtration flow rater

FCW backwash benefits



FCW backwash benefits:• excludes mikcobiological

contamination caused by atmospheric air

• no wine oxidation durring filtration

• reduced risk of membrane damage by pressure peaks

• wine is not hydromechanicaly stressed by another pump


FCW backwash benefits


Automatic system



Fully automated FCW benefits:• provides nonstop process

• feed and circulation pump controlled by frequency drive – very gentle filtration compare to manual and semi-automated systems

• system handles filtration and sanitation without operator presence

• enables integrity test before each filtration


Fully automated FCW benefits


• provides several types of filtration and options of dealing with wine and sludge

• remote control option (sms)

• optional turbidity meter


Fully automated FCW benefits
