Technion Israel Institute of Technology Introduction

1. Technion Israel Institute of Technology Introduction Denis Shteynberg M.Sc Aug 2013

3. Techion - Israel Institute of Technology • Established at 1912 • Located in Haifa , Israel • The university offers degrees in science and engineering, and related fields such as architecture, medicine, industrial management and education • Has 18 academic departments and 52 research centers • 13,000 students (9500 undergraduate) • 3 Nobel prize winners

4. Haifa city • 3rd largest city in Israel • Pop of 300,000 • Located at the north of Israel • The city is a major seaport located on Israel's Mediterranean coastline in the Bay of Haifa • Has the shortest subway line in the world

5. The faculty Civil & Environmental Engineering Vision • Maintain and enhance the leading position of the Faculty of Civil & Environmental Engineering amongst the top departments in the world. • Position the Faculty as the national center for research & development and human resources for the sustainable development of the national infrastructure of Israel. • Consist of 9 departments : structural engineering, construction management, Geotechnology , Building Materials, Performance & Technology , Water Resources & Hydraulic Engineering , Transportation Engineering , Mapping & Geo-Information , Agricultural Engineering and Environmental Engineering.

6. About myself • 29 years old • Born in Belarus • B.Sc Biotechnology engineering • Worked for 3 years in a Biotech start-up company • Started master study last year (wastewater and gray water treatment)

7. Flow-Pressure apparatuses for identification of individual domestic appliances Denis Shteynberg Technion – Israel Institute of Technology July, 2013

8. Introduction • Determine typical use patterns of domestic appliances • Simulate diurnal individual domestic wastewater streams for input into an integrated dynamic simulation model • To characterize GW composition

9. Introduction • Current data is nearly 20 years old, no longer represents actual behavior patterns nor the flow characteristics of modern appliances • Need to find a way to obtain flow rates and volumes of wastewater discharged from individual microcomponents in multiple households • Several different techniques – past and modern : Diary Survey ,SIMDEUM ,HydroSens,FlowTrace,Identiflow

10. Our System

11. System concept To recognize the usage pattern of the different water using elements in the domestic use (dish washer, shower, toilet flush, etc.) • Data obtained based on continuous analysis of volumetric flow rate changes within a home’s plumbing system • The data will be collected with data logger which is connected to the standard water meter and the automatic GW sampler • After the collection of the data water patterns will be recognized and analyzed (using Matlab or another software)

12. System components • Standard water meter • Controller/data logger reads the pressure and the volumetric flow rate (sample every sec.). Also controls the automatic seweragesampler • GW automatic sampler • Pattern recognition software (being developed)

13. Water usage GW “production” System flow chart GW outlet Fresh water inlet Water meter & pressure probe Automatic GW sampler Data logger/controller Gray water characterization Usage pattern analysis Volumetric flow and GW quality characterization of single appliances

15. Project status • Two units of the apparatuses were built and tested • The system was installed in five houses ( 3 completed , 2 on the run ) • Duration of data acquisition in each house is 3 weeks • Four of the houses have GW systems • GW sampling haven’t been done yet
