DESIGN STUDY

Chemical Treatment

• Medium to High Investment• Higher Maintenance & Operational cost• Requires qualified personal(analysis, treatment, recording)• Yearly Upgrades• DG storage• High Administration• Higher Carbon Footprint• Limited Water re-use (max. 70%)

Vacuum Distillati

on

• Medium Range Investment• Fully automatic (7/24)• Daily effort <1hr• No additional qualified personal required• Limited amount of chemicals (defoamer, caustic soda)• Low administrative, operational & maintaining cost• Lower carbon footprint• High Water re-use (up to 98%)• No upgrades necessary• Process can be observed and controlled via Ethernet

KEY FIGURES

Energy

60 kWh per 1000 litre

= 3631.8kWh x 0.06 AUD

= 217.90 AUD

Treatment cost per month (= 60’000 litres)

Process Additives

25 litres of Defoamer25 litres of Caustic Soda5 litres Cleaning Agent

= 230,-AUD

Labour

10 hrs

= 400,-AUD

~850,-AUD/month = 1.4 cents/litre compared with 20 cents/litre on chemical treatment (excluding analysing cost = 400,-AUD/monthly)
