Water reuse - not just to produce a delicious beer

Water reuse is not just an alternative anymore! Water reuse is the alternative for sustainable water use!

Sustainability Factors

Best environmental, economic and technical solution

Environment LCA Social Quality Economic LCC

• Link economic, environmental, and social impacts to

reuse solutions

• The Life Cycle Assessment (LCA) informs on the

environmental impact of the solution

• Full system Life Cycle Cost (LCC) adapts the solution to the

economic limitation

• The adapted effluent quality leads to safety at the point of

use and social acceptance

• Optimal solutions vary based on plant size, local and

regional conditions, requirements, flexibility, etc.

Outcomes?

• Various reuse effluent quality requirements can be achieved by treatment systems that are

ready to be implemented as they are based on available technologies.

• The total environmental impact does not need to be higher than conventional wastewater

treatment despite the fact that wastewater is treated to a reuse water quality

• In fact, the total environmental impact for some of the optimized ReUse-systems can be

lower than for traditional treatment systems as far as this can be quantified considering all benefits the reuse of wastewater generates!

• Costs for different reuse applications are in the same range or even lower than reported

costs for existing conventional wastewater treatment plants in Sweden!

 Thus, wastewater reuse is feasible today!
