The water issue

The importance of water is

• ften undervalued.

We must all reconsider our current relationship with this limited resource. Companies are realising water related risks could limit future growth.

• Competition over abstraction
• Climate threats
• Irregular quality
• Accidental contaminations

Why a sustainable approach?

Production needs Water Scarcity and Safety Compliance Costs Image

• Increase of production
• Continuous and safe water supply
• Avoid production shutdown
• Environmental guidelines
• Shareholders expectations
• Public opinion and corporate image
• Sustainable development
• Water abstraction limits
• Discharge limits
• No discharge possible
• Water consumption costs
• Discharge fees
• Need for large volumes

Opportunity to treat and reuse water

Step 1 – cost reduction opportunities

Alternative natural water sources

• Well
• River
• Sea
• Borehole
• Rainwater harvesting
• Effluent minimisation
• Demand management
• Bund water management

Step 2 - reuse applications

Result – a sustainable industry

Savings that can be made

Case study 1 - distillery

Client needs:

• Create a flagship manufacturing site that demonstrates their ambition for a sustainable business

using renewable energy.

The solution:

• Commissioning of a new bio energy facility.
• VWT contracted to design & build the dewatering & aqueous treatment plant.
• Plant generates renewal energy from spent wash & liquors.
• Spent grain is separated & used to provide fuel for the biomass boiler.

Case study 1 - distillery

The results:

• Annual CO2 emissions reduced by 95% (56,000 tonnes)
• 80% of distillery energy requirements from biogas & biomass.
• 98% of thermal steam recovery.
• Over 60% of water recovery.

Case study 2 - dairy

• Operator supplying around 30% of milk consumed within the UK.
• 1.3 litres of water required for every litre of milk processed.
• Clear effluent produced from the onsite DAF and MBR waste water system that offered the opportunity for

reuse.

• Saving on discharge costs.

The solution:

• Trials confirmed effluent from the MRB could be fed directly to an Reverse Osmosis system.
• Reverse Osmosis system to recover 200,000 litres a day.

Case study 2 - dairy

The results:

• Reduction of mains and waste water charges by recovering

200,000 litres per day from steam raising and clean in place systems.

• Return of investment achieved in 2.5 years
• Environmental benefits

What’s next...focus on water!

Focus on Water

Three key steps for the beverage industry to consider:

• Work together to overcome misconceptions through clear,

consistent and continuous communications about water reuse in the industry.

• Emphasize the value of recycled water as a sustainable

resource that will help meet future demands in the industry.

• Take a more integrated approach to water management.
