Brewing - water

Filtration

Confirm equipment uses water at its recommended consumption

• if higher savings are possible

Reduce water for pushing through beer on brand changeover

• where possible follow one quality with another of similar colour
• little need for water between brands

Filter aid precoating is possible with slurry in bright beer

• reduced beer losses and water usage
• will increase pick-up of metal ions into beer, however

Consider crossflow microfiltration for beer filtration

• membrane technique, sometimes preceded by centrifugation
• most commonly polymeric membranes, possibly ceramic
• process economics do not favour kieselguhr plant replacement
• unless new plant or kieselguhr plant worn out
• the compact plant reduces water requirement
• at least 15% less

It may be possible to employ a reduced cleaning cycle if the next product has similar colour

• optimise product scheduling
• also reduce or eliminate chase liquor requirement
• also for stabiliser vessels and buffer tanks
