4. Introduction: Market Drivers & Outlook
Key market drivers:
Increasing demand of different beverage types - Non alcoholic & alcoholic
Segment considered to be one of the most robust growth segment amongst food and beverage
Capacity expansion by existing manufacturers is increasing the need for upgrading and installing new equipment along with the development of new technologies
Increasing demand for safe, cost effective and sustainable beverages means participants are striving to improve the operational efficiency while increasing output and profitability
Water is an essential input for the food and drink industry, both as an ingredient and key processing element. Water is also used as a cooling agent in many production processes. Clean water is vital for food safety as it is used to clean and sanitise floors, processing equipment, containers and ingredients, and can account for up to 70% of a company’s water use

5. Requirements for alternative water sources

6. In some cases it is not possible to utilise all of these water sources
Alternative Water Supplies
There are a number of options available:
Wastewater reuse/recovery
River Extraction
Other natural water sources
Borehole
Water reuse - sometimes not possible for food contact/ingredient
River extraction - Rain & drought periods can impact quality and availability. Local contamination such as farmland to be considered in use…
Rain water recovery - Limited to periods of rainfall - unpredictable
Seawater - if location appropriate - seawater requires specialist equipment, asset protection critical (corrosion)
Lagoons/Lakes - Water quality, abstraction limits etc...
In some cases it is not possible to utilise all of these water sources

7. Why Use A Borehole? Benefits?
A borehole can be a self sufficient water supply
Low cost compared to towns water or equivalent
Reduced demand on local water supplies
Sustainability benefits
The water is extracted from the ground ‘aquifer’ and pumped to the surface having passed through several layers to help purify the water & remove contaminants - however depending on the intended water use additional treatment maybe required.

8. Borehole Water Challenges
High quality water, is a key driver for the Food & Beverage markets:
Potential Issues:
Achieving a consistent quality
Reliability & availability of supply
Water Quality (Iron/Manganese/Microbiological Quality/Conductivity)
Rainfall/Dry Periods can affect quality/availability
Multiple boreholes
Abstraction Flow Limits
Taste, odour and microbiological issues can occur if not treated properly
Product safety is critical when introducing water for food contact or ingredient
Over abstraction will lower water table reducing flows from other nearby boreholes and any rivers supplied by ground water

9. Typical Borehole Treatment Technologies
Media-filtration
A process for removing suspended or colloidal particles
Benefits
Physical function : retention of suspended particles (suspended solids, iron and manganese precipitate.)
Physical-chemical : adsorption of micro pollutants (pesticides, detergents, chlorinated solvents, sapid components, etc.)
Manganese removal with manganese dioxide.
Note:
Sometimes several stages maybe required to deliver the required water quality

10. Typical Borehole Treatment Technologies
Ultra-filtration
Pressure driven technology to remove suspended solids, bacteria, endotoxins & viruses from water
Benefits
Ultrafiltration is an excellent technology for ensuring consistent ultrapure water quality with regard to particles, bacteria and pyrogens
Efficient operation
Proven use in borehole water treatment , as well as recycling/reuse.
Note:
RO cannot eliminate all bacteria or viruses
Sometimes several stages maybe required to deliver the required water quality

11. Typical Borehole Treatment Technologies
Typical treatment options are as follows:
Ion Exchange
Easy to use solution for hard water reduction
Benefits
For removing specific contaminants
Nitrate reduction
Hardness reduction (softener)
Ease of operation Twin or duplex configuration with either time-clock or water-meter operation
Note:
RO cannot eliminate all bacteria or viruses
Sometimes several stages maybe required to deliver the required water quality
In some applications more than one type of treatment option can be used for borehole treatment

12. Typical Borehole Treatment Technologies
Typical treatment options are as follows:
Reverse Osmosis
Semi permeable membrane, removes water impurities upto 99% dissolved solids
Benefits
Separate and remove a large majority of water impurities
Ensures the control of potential microbial contamination
Low footprint
Minimum operational requirement
Note:
RO cannot eliminate all bacteria or viruses
Sometimes several stages maybe required to deliver the required water quality
In some applications more than one type of treatment option can be used for borehole treatment

13. Typical Borehole Treatment Technologies
Nano-filtration
Nanofiltration is a membrane filtration process with pore sizes which are smaller than those used in microfiltration and ultrafiltration
Excellent for low TDS waters such as surface or groundwater
Benefits
Effective to remove hardness, pesticides, bacteria and pollutants in drinking water
Readily used for treating drinking water by removal of contaminants
Note:
Nano systems treat drinking water by removing:
- Total dissolved organic carbon (COT/COD)
- Natural organic matter
- Pesticides
- Bacteria and Viruses
- Hardness
- Nitrates and sulfates
- Partial TDS
- Cryptosporidium

14. Typical Borehole Treatment Technologies
Disc-Filter
Woven media partially submerged disc for polishing, water reuse
Also suitable for P treatment
Benefits
Excellent fine filtration of intake water
Mechanical self cleaning
Small footprint
Hydrotech Discfilter uses woven cloth filters mounted on multiple discs providing a large filter area in a small footprint. The filter media on the partially submerged discs filters solids from the water. Accumulated solids are cleaned via the counter-current backwash system. Filtered water flows through the disc media to be collected in the collection tank. Hydrotech Discfilter units are in widespread use worldwide, finding applications in stormwater treatment, membrane pretreatment, phosphorous removal, water reuse and wastewater filtration.

15. Reference Case Studies

16. United Kingdom Food & Beverage, Brewery DIAGEO Packaging, Runcorn
Challenge
The Diageo site at Runcorn processes beverages produced elsewhere in the group. These are conditioned and packaged into bottles, kegs and cans prior to distribution.
To support the packaging lines the factory needs a consistent supply of utilities including steam, compressed air, refrigeration, nitrogen, carbon dioxide and filtered process water.
Solutions
Raw water filtration & distribution on site
Veolia also provide 24/7/365 support for energy and utility plant and distribution systems, plus 100% remote utility monitoring for continuous production.
Benefits
United Kingdom
Runcorn
Beer bottling site
Veolia scope
Steam, Low Temperature Hot water, Cooling,
Supply of high voltage electricity and industrial gases (nitrogen and CO2)
Raw water filtration and water distribution etc.
Contract duration: 15 years
Reduce Operating Costs: Saved £100,000 in Effluent treatment
Maximize productive uptime: Enhanced plant reliability and better fluid availability

17. Food & Beverage, Distillery Water Services: Annandale Distillery
United Kingdom
Annan
Challenge
A historical distillery that closed in 1920 then bought by Prof David Thomson, a Scientist and Teresa Church, a Nutritionist. The new owners wanted the distillery to be sustainable and as far as possible, self-sufficient in water.
The use of mains water would be expensive and potentially of variable quality, or the distillery could use its own onsite borehole which would be of consistent quality, but would require more extensive treatment
Solutions

19. Conclusion
Water scarcity is a key concern for the drinks industry, as disruptions in operations due to water availability, increases in water expenses and other adverse water-related impacts would be detrimental to the industry’s competitiveness
As highlighted, the drinks industry has made good progress in water use reduction and is committed to voluntarily improving water management practices further, but more can and should be done
