Water reuse & recycling
The key to sustainable water management
Why water recycling is not a luxury, but the order of the day. There is only a fixed amount of fresh water available and while the earth’s natural resources continue to dwindle, the global popula-tion is increasing by 80 million people annually. However, popula-tion growth and urbanisation are by no means the sole causes of ever-greater water shortages, as climate change, agriculture and industry, infrastructure deficiencies, pollution, the overexploitation of groundwater reserves, water wastage and the building of dams also constitute contributory factors.
2016: 7.4 billion people2050: 9.6 billion people
WABAG – a water reclamation pioneerWABAG is an expert in the field of water reuse and recycling and in some areas represents a pioneer. We were one of the first companies to develop modern water reuse and recycling con-cepts and during the past two decades have implemented over 50 schems involving a wide range of applications.
What makes WABAG a preferred partner?�� An extensive technology portfolio�� Proven process know-how and experience�� The provision of complete solutions: EPC, DBO, BOOT�� Experience as a reclamation plant operator �� Multinational experience, which ensures an understanding of different local needs�� In-house R&D centres in Austria, India and Switzerland �� The completion of over 1,200 water and used water treatment plants since 1995.�� Having built the worldwide first Direct Potable Reuse Plant in Windhoek, Namibia.
A practical and sustainable solution: water recyclingIn view of the urgent need to conserve existing resources, the implementation of water recycling concepts is of enormous im-portance. Intelligent reclamation systems can make a significant contribution to the increased water availability needed to meet private, commercial, agricultural and industrial demands, and improve supply reliability. Furthermore, reclamation systems con-sume less energy than alternatives such as seawater desalination.
... by 2030,
the global water re-quirement could already ex-
ceed the reserves available by some 40 per cent. As a result every second global
inhabitant would suffer from a shortage of water.

Recycled water for irrigation
Agricultural water reuse - A contribution to food security. Today, our planet needs to feed seven billion people. By 2050, this number will rise to nine billion.
Agriculture is the world’s largest water consumer and around 70% of current, global water consumption is em-ployed for agricultural purposes.
Global population expansion is being accompanied by increas-ing food demand and thus a rise in the water volumes needed for farming. It is estimated that demand will climb by around 20% in the period up to 2050 and this water will then be unavailable for other purposes such as for drinking or in ecosystems.
One obvious solution is the employment of an alternative source, which is often close at hand. This is the outflow from used water treatment plants. These are generally equipped with mechanical/biological treatment systems and can be relatively simply, but effec-tively supplemented with a tertiary treatment phase. Filtration and disinfection represent classic methods in this regard and cleaning performance can be upgraded by the use of MBR, MBBR or BAF. The result is the availability of a large volume of recycled water.

The world’s conurbations continue to grow. At present, half of the global population is urban and two additional urban dwellers are added every second. Urban popula-tions in Africa and Asia are set to double between 2000 and 2030.
Therefore, intelligent water recycling systems represent a key to the sustainable, socio-economic development of cities and nations.
Against this background, in many parts of the world used wa-ter treatment plants are increasingly being employed as a raw water source. The treated used water is suitable for reuse as recreational water or urban service water - street cleaning, ir-rigation, firefighting, landscaping, toilet flushing, etc..

Industrial reuse & recycling
Transforming used water into a valuable production factor
Over 20% of global fresh water consumption relates to in-dustry and in the industrialised countries, this figure rises up to 60%. Wherever potable water supply is endangered, the public authorities first reduce the supply to industry. Alternative sustainable solutions are to be found in the used water flows from industrial and municipal treatment plants. Tailor-made treatment systems enable the reuse of the cleaned used water for industrial production in various forms:
Reuse of industrial and/or municipal effluents for:�� Cooling tower make-up water�� Boiler make-up water�� Process water - e.g. for Purified Terephtalic Acid (PTA) production�� Industrial service water - e.g. fire fighting, cleaning
WABAG has already equipped industrial plants from a diversity of branches with resource- and cost-efficient water reuse and recycling systems. Using the company’s comprehensive process portfolio, our experts plan individual and optimised concepts for every operation, from basic tertiary treatment up to zero liquid dis-charge.
Industrial water recyclingClosed, integrated water management systems with internal used water treatment allow a drastic cut in the water consumption of production plants. In addition, the volume of used water, which is returned to the natural water cycle, is also reduced. Moreover, not only can an important contribution to water conservation be made, but also financial savings can be achieved with regard to operational and production costs, and the water supply secured.
Benefits for industry and the environment: � A secure water supply � Consistent water quality � Reduced fresh water consumption, which preserves water resources
� Cut in used water volume and charges � Reduced production/operating costs � Fast Return on Investment � Facilitation of regional, socioeconomic development
� Green technologies – a contribution to environmental sustainability
Wherever potable water supply is endangered, the
public authorities first reduce the supply to
industry.

Direct potable reuse
Turning secondary effluent into drinking water
The New Goreangab WTP in Windhoek, Namibia
Windhoek, Namibia
In many regions of the world, access to clean drinking water is not a matter of course. A secure supply is frequently only possible through the use of alternative resources. Therefore, reclaimed used water represents a viable option for potable water augmentation. Naturally there must be absolute certainty that the utilisation and consumption of this water do not involve any risks to humans.
Multiple Barriers – before, during and after the water treatment. A system of multiple safety barriers is installed, not only during, but also before and after the water treatment process. The first fundamental barrier is provided by the fact that industrial and domestic effluents are strictly separated followed by an extensive pretreatment prior to reaching the reclamation plant. The domestic used water from the city is conditioned using the Gammans used water treatment plant (nutrient elimination with the UCT process) and polished in maturation ponds before cleaning in the advanced multi-barrier system comprised of nine treatment steps. This employs a series of safety barriers for all crucial contaminants and thus guarantees the reliable fulfilment of strict standards.
WABAG has the know-how and the technologies required to provide drinking water from domestic used water, as demonstrated by the world’s first direct potable reclama-tion plant in Windhoek:
The city of Windhoek receives water from three sources, one of which is the globally renowned Goreangab water reclamation plant complex. This unique reclamation plant transforms domes-tic secondary effluent into high-quality drinking water by means of the latest water technologies.
The New Goreangab plant was completed in 2002 and represents the first direct potable water reclamation plant worldwide. It pro-duces 21,000 m3 of high-quality potable water per day, which con-stitute 25% of the total volume of water consumed in Windhoek.
