As coberturas e fachadas mediterrânicas, vivas e produtivas promovem o bem estar e a qualidade de vida das populações e contribuem decisivamente para o aumento da resiliência das cidades. Por esta razão é essencial não apenas o conhecimento das soluções existentes que melhor se adaptam ao nosso clima, como ainda o desenvolvimento das competências técnicas essenciais para a boa implementação daquelas soluções. O enfoque deste Workshop está na demonstração da integração da dimensão verde nas cidades e das oportunidades de intervenção conducentes à melhoria do desempenho energético dos edifícios, à redução do “efeito ilha de calor”, à boa gestão das águas pluviais, à reciclagem de águas cinzentas, à melhoria da qualidade do ar, ao aumento da biodiversidade e à segurança alimentar das populações urbanas, sempre assentando nas melhores e mais adequadas tecnologias disponíveis.

Transcript of "Jochen Scheerer"

  1. 1. COBERTURAS E FACHADAS MEDITERRANICAS VIVAS E PRODUCTIVAS IIRecycling grey water in green façades October 20 th, 2011 – LISBON Dr. Jochen Scheerer
  2. 2. Recycling grey water in green façades Company Presentation ASEPMA is an engineering company specialized in water management, treatment and reuse of non potable water. Since its beginning in 2003, ASEPMA has offered its services to a great number of clients coming from the field of public administrations all kind of industries as well as private customers. Those services include the whole range of tasks related to the management of water cycle beginning with consultancy, project design, installation and maintenance and control of treatment facilities for non potable water. Besides standard compact treatments, ASEPMA offers alternative solutions for waste water treatment using constructed wetlands, both horizontal and vertical. The later based on a innovative technology patented by ASEPMA. Since January 2009, ASEPMA has become a business unit of the ABM Group dedicated to consultancy, service and technical solutions related to industrial waste water, urban sewage, grey water and rain water management.
  3. 3. Recycling grey water in green façades What kind of water restrictions exists in the Mediterranean area? Periodic scarcity Episodes of drought and advancing of desertification Water prices are expected to Increasing costs continue increasing faster than in the past. (Since 2005, water prices in Spain increased 28 % in average) There is a growing number of legal Legislation requirements on national, regional and local levels fostering water saving.
  4. 4. Recycling grey water in green façades Local requirements Fostering of water saving measures and sustainable use Aim of water. New buildings and constructions. Field of application Rehabilitation and reforms of existing buildings. Public buildings Rain water Grey water Pool water
  5. 5. Recycling grey water in green façades Current water management concept Usage Drinking water Waste water
  6. 6. Recycling grey water in green façades Alternative water management concept Drinking Grey water Water Use Waste water Reclaimed Black water water Treatment and regeneration
  7. 7. Recycling grey water in green façades How works waste water treatment? Waste water treatment is the sum of different individual operations which we can distinguish into mechanical, physical and biological operations. The aim of such treatment is to reduce or eliminate certain undesirable characteristics of the waste water.
  8. 8. Recycling grey water in green façades Main steps of waste water treatment Pre- Secondary Tertiary Treatment Treatment Treatment Pre- Treatment: Elimination of solids and grease by mechanical, physical and chemical means. Secondary Treatment: Elimination of organic substances and nutrients by biologic means. Tertiary Treatment: Advanced elimination of nutrients and hygienization by physical, chemical and biological means.
  9. 9. Recycling grey water in green façades Main steps of waste water treatment Pre- Treatment: •Elimination of solids and grease by physical, chemical and mechanical means •Reduction of 20% BOD i 50% Solids Mechanical sieves Grease separators Septic tanks Decanters, anaerobic digesters Physic chemical treatments
  10. 10. Recycling grey water in green façades Main steps of waste water treatment Secondary Treatment: •Elimination of organic substances. •BOD: <25 mg/L O2 •Solids : <60 mg/L Activated sludge Percolator Total oxidation Bio filters and or wetlands
  11. 11. Recycling grey water in green façades Main steps of waste water treatment Tertiary Treatment: •Elimination of nutrients like nitrogen and phosphorous •Elimination of microorganisms Adsorption Ozone Membrane filtration Wetlands
  12. 12. Recycling grey water in green façades Classical concept of urban water reuse Main problem Distance
  13. 13. Recycling grey water in green façades Concept of IN SITU treatment and reuse Treatment and regeneration of grey water or waste water close to the point of reuse. Applications of water which do not require drinking water quality : Irrigation of public parks and gardens . WC. Cleaning of external surfaces .
  14. 14. Recycling grey water in green façades Bio Treatments: WETLANDS The use of artificial wetlands in waste water treatment permit to benefit from natural processes which eliminate or reduce non desired substances from the water: Creation of an active substrate (roots, gravel), which permits the growth and metabolic activity of microorganisms. Reduction of the contamination -up to 90%- thanks to the activity of microorganisms, which under aerobic conditions metabolize organic contaminants into carbon dioxide and other nutrients for the plants. Very efficient elimination of carbon, nitrogen ad phosphorous. Possibility to eliminate even heavy metals by using the processes of selective uptake and accumulation by plants (known as phytoremediation)
  15. 15. Recycling grey water in green façades Bio Treatments : WETLANDS
  16. 16. Recycling grey water in green façades Bio Treatments : WETLANDS ADVANTAGES DISADVANTATGES - IN SITU treatment. - Space requirements. - High efficient treatment. - Energy consumption is very low or nil. - Increase of biodiversity. - Environmental Improvement by CO2 fixing, and oxygen production) Difficult to use in urban - Positive landscaping. areas!
  17. 17. Recycling grey water in green façades Bio Treatments : WETLANDS In large cities there is no space for a horizontal wetland ! But... Why it can not be done vertically? BABYLON
  18. 18. Recycling grey water in green façades Bio Treatment: The Babylon® System A green façade where grey water is circulated vertically using mainly gravity force. Obtaining treated and regenerated grey water using approved wetland technology. However vertically!
  19. 19. Recycling grey water in green façades Bio Treatment: The Babylon® System Advantages: All advantages known from wetland treatments. In addition: A solution for the space problem. Improvement of thermo isolation of the buildings due to known benefits of ventilated façades and additionally due to evaporation from the plants. Acoustic isolation. Attractive element in architecture with additional function as IN SITU water treatment .
  20. 20. Recycling grey water in green façades Bio Treatment: The Babylon® System Little history on green façades The hanging gardens of Babylonia where constructed by Nebuchadnezzar 2nd around 600 b.C. Considered one of the 7 miracles of the world, they were about 25 meters high. According to the descriptions of Ctesias, 400 b.C. there where already plants of the Phragmites species used in these installations.
