1 Dr. Malamis Dimitris National Technical University of Athens School of Chemical Engineering Unit of Environmental Science and Technology “ Water Resources Management: Needs and Prospects” Jordan, Amman, 22/04/2013

2 INTERWASTE Project INTERWASTE is co-funded by EU LIFE+ ENVIRONMENT INTERWASTE Partners National Technical University of Athens (Greece) Cyprus University of Technology University of Nicosia (Cyprus) Proplan Ltd (Cyprus) Department of Environment Ministry of Agriculture, natural Recourses and Environment.

3 Aim of present work Development of an integrated system for sustainable treatment of Biodegradable Organic Waste and Municipal Wastewater with zero discharge Production of high quality, added value products Electricity and heat from renewable sources (organic waste) High quality effluent that can be reused (i.e. irrigation) High quality soil conditioner-compost This can be achieved through the integration of aerobic and anaerobic processes by employing: Membrane BioReactor-Anaerobic Digester MBR - AD

4 Potential users of the integrated MBR-AD system Generally places where production of waste and demand of the obtained products from waste treatment co-exist: Remote de-centralized regions Small communities Residential areas (i.e. blocks of flats) Hotels

5 MBR AD BIOGAS Digestate Flow Sheet diagram MBR - AD

6 The integrated system The MBR – AD Unit

7 Operating parameters MBR 1,5 m 3 /d municipal wastewater sludge outlet– 100 l/d => to AD AD Daily preparation of substrate. Formation of a mixture of 150L with 10% TS consisting of food waste and sludge from the MBR 150 L of digestate are separated into liquid and solid phase Solid phase => solar drier Liquid phase => recirculated to the MBR

8 MBR Flow Sheet diagram MBR - AD

9 MBR – BUFFER TANK Stainless steal vessel 8,5 m 3

10 MBR Flow Sheet diagram MBR - AD

11 MBR Feedstock Municipal Wastewater from Buffer Tank (1,5 m 3 /d) Membrane BioReactor (MBR) system for wastewater treatment Effluent (water) Sludge Sludge fed to the Anaerobic Digestion System

12 AD Flow Sheet diagram MBR - AD

13 Homogenization Unit – AD Substrate preparation Homogenization Unit: Sludge from the MBR Food waste Target 10±2% TS

14 AD Flow Sheet diagram MBR - AD

15 Anaerobic Digester Substrate from the Homogenization Unit Digestate Biogas Total volume 8,5 m 3 Operating volume 4,5 m 3 Substrate feed 150 L/d with 10 % TS Mesophilic Temperature (≈35 o C) SRT = 20-25days

16 AD – Biogas System Biogas Storage (Balloon 3m3) Biogas Meter Scrubber for biogas cleaning (VOC, ΝΗ3) Packed bed Scrubber (H 2 S) Biogas Composition Analysis CHP unit

17 Biogas Cleaning System Scrubbers for biogas cleaning CHP unit for energy production

18 Digestate Flow Sheet diagram MBR - AD

19 Bag Filter – Treatment of Digestate

20 ΜΒR performance % COD reduction

21 ΜΒR Performance TN reduction

22 ΜΒR Performance - NH 4 + reduction

23 Biogas Composition CH 4 = 59%, CO 2 = 40 % AD Performance – Biogas Production

24 Biogas - Energy Balance Electricity Biogas 100% Heat 33% 3.5 % 22% 31.5% 55% 35% losses 10%

25 MBR-AD potential applications Treating Biowaste & Municipal wastewater of a community with population of 1,000 persons in Cyprus covers the electricity needs of around 55 inhabitants or 19 households Produces 150 m3/d of water that can be used for irrigation Treating Biowaste & Municipal wastewater of a 5 star Hotel in Cyprus covers 3.4% of the needs for electricity and covers 3.6% of the heating needs Produces 250 m3/d water that can be used for irrigation
