1 MATHEMATICAL MODEL STUDY OF THE EFFLUENT DISPOSAL FROM A DESALINATION PLANT IN THE MARINE ENVIRONMENT AT TUTICORIN Presented by Mr.Danish.D.R M.Tech Coastal Management Institute for Ocean Management Anna University, Chennai Tamil Nadu, India

2 PRESENTATION OUTLINE INTRODUCTION STUDY AREA OBJECTIVE METHODOLOGY GOVERNING EQUATION AD Equation Concentration Plant details RESULTS AND DISCUSSION CONCLUSION

3 INTRODUCTION Desalination - removal of dissolved minerals of the sea water Why Desalination? Scarcity of water and increase in demand for water Proposal for desalination plants of 1 MLD capacity units along the eastern coast of Tamil Nadu Greatest challenge brine discharge and disposal in sea water By-products of SWRO desal plants maintains ambient temperature but increases the salinity by more than 1% There is no better alternative for brine disposal other than the marine outfalls 9% of desalination plants dispose their effluents through specially designed outfalls Location of discharge outfalls to be present in less sensitive coastal region

4 OBJECTIVE To determine optimum location for the outfall. To predict the fate of the effluent using numerical model (MIKE 21)

5 STUDY AREA

7 METHODOLOGY HYDRODYNAMIC DATA (SECONDARY DATA) TIDES CURRENTS MODELLING OF EFFLUENT DISCHARGE MIKE21 (FLOW MODEL) SAMPLES

8 GOVERNING EQUATION - AD Equation hh + uuu + vvv = h. D x. + h. D y. F. h. c + S Where, c : Compound concentration (arbitrary axis) u, v : Horizontal velocity components in the X,Y direction (m/s) h D x, D y : Water depth (m) : Dispersion coefficient in X,Y direction (m 2 /s) F : Linear decay co-efficient (Sec -1 ) S : Qs, (Cs-C) Qs : Source/Sink discharge (m 3 /s/m 2 ) Cs : Concentration of compound in the source/sink discharge

9 GOVERNING EQUATION - CONCENTRATION C = (C 1 X 1 +C 2 X 2 )/X 3 Where, C 1 - Sea water concentration kg/m 3 C 1 - Drinking water concentration kg/m 3 C 2 - Brine concentration kg/m 3 X 1 - Drinking water capacity MLD X 2 - Brine outfall capacity MLD X 3 - Seawater intake capacity MLD

10 PLANT DETAILS PLANT DETAILS Plant capacity Plant intake Brine outfall Sea water concentration Brine Concentration DESCRIPTION 1 MLD ( m 3 /hr) 237 MLD (9875 m 3 /hr) 137 MLD ( m 3 /hr) 35 PSU 48 PSU (13 PSU in excess)

23 TIME SERIES FOR 34 DAYS Wind Direction (Degrees) Wind speed (m/s) Wind Direction Wind speed No of Days

24 DISPERSION FLOW MODEL FOR VARYING WIND SPEED FOR 48 DAYS AND 34 DAYS

25 CONCLUSIONS The simulation model clearly shows no effluent has moved towards the shore or gets accumulated. The difference between the salinity of the brine and the sea water is about PSU, not much different from the ambient salinity. Thus these parameters show that the point of outfall is efficient and does not affect the surrounding marine environment
