In a world where responsible water management is essential to address environmental and resource challenges, graywater reuse emerges as an innovative and sustainable solution
what is meant by gray water?
Graywater originates from sinks, showers and bidets, and is characterized by a significantly lower organic load compared to blackwater, which originates from toilets and contains fecal material. Due to their lower level of contamination, they are much easier to treat for subsequent reuse, which implies a more efficient use of resources compared to blackwater treatment. It is estimated that approximately 75% of the wastewater generated in homes and hotels corresponds to graywater, with an average of between 50 and 100 liters per person per day, which highlights its potential as a valuable resource.  
Gray water reuse plant: AZUD WATERTECH GW
To address this challenge, AZUD presents an effective solution: the greywater treatment plantAZUD WATERTECH GW. This plant employs several technologies that combine to achieve high quality Filtration and contribute to solving this problem
Disc Filtration.
Filtration equipment with disc technology and air-assisted self-cleaning systemAZUD HELIX AUTOMATIC AA. A Mechanism of high efficiency and very low water and energy consumption, for the removal of suspended solids of inorganic and organic nature and also provides protection to the following equipment and membranes
Filtration by ultrafiltration membranes.
Ultrafiltration membrane technology guarantees the quality of treated water by eliminating unpleasant odors, avoiding sludge generation and reducing noise nuisance
Disinfection.
Oxidant dosing to remove organic matter. In addition, there is the option of using hypochlorite dosing or UV lamps to guarantee water disinfection. These plants are compact and can be disassembled by modules, which facilitates their installation in hard-to-reach places and their subsequent operation
Success stories in urban graywater reuse
These gray water reuse and treatment systemsAZUD WATERTECH GW have been implemented around the world. Notable examples includehotels where they are reused for the Irrigation of their gardens andoffice buildings that reduce their environmental footprint by recycling gray water for flushing toilets
Gray water reuse in office building: Synergy
A recent project that deserves special attention is located in Montevideo, Uruguay, carried out for the Uruguayan company SINERGIA, which is dedicated to therental of shared workspaces and flexible offices. In one of its most outstanding buildings, with coworking capacity for more than 200 people and equipped with restaurants and entertainment areas, a gray water and rainwater reuse plant has been implemented. This measure has made it possible to reuse water in toilet cisterns, thus achieving asignificant reduction of up to 30,000 liters of potable water per daythis has contributed to positioning SINERGIA as one of the most sustainable buildings in Uruguay, having obtainedthelEED Platinum Core & Shell certificationwhich guarantees that the building was constructed and operates with the least possible impact on the environment
LEED Certification
ThelEED (Excellence in Energy and Environmental Design) Platinum Core & Shell certification is a very high level of certification awarded by the USGBC (U.S. Green Building Council) for sustainable building projects under the LEED (Leadership in Energy and Environmental Design) certification system. LEED certification is used to evaluate and recognize buildings and projects that have implemented sustainable and environmentally friendly practices
The case of the SINERGIA building illustrates in a compelling way how greywater reuse can transform the sustainability of buildings and businesses. Not only does it reduce potable water consumption, but it also contributes significantly to resource conservation and a reduced environmental footprint.
