- 1. ENVIRONMENTAL ENGINEERING PROJECT [Wastewater problems in Kuwait] DONE BY: Waleed Yahia Abd-Elatif 2111130477 Rami Samir Al-Sahar 2111129285 Mohamed Ahmed El-Mokadem 2111130439
- 2. INTRODUCTION ? Three scientific papers related to wastewater treatment : 1. Waste water quality and reuse in irrigation in Kuwait using microfiltration technology (MF) in treatment. 2. Feasibility of long-term irrigation as a treatment method for municipal wastewater using natural soil in Kuwait. 3. Hydrogen Sulfide Emission from the Ardiyah SewageTreatment Plant in Kuwait.
- 3. MICROFILTRATION TECHNOLOGY ? The main objective of the paper is to study the secondary effluent wastewater treated with MF unit for irrigation purpose. ? A MF unit was installed in the Riqqa wastewater treatment Plant. ? Samples were collected and compared to the standards for irrigation in Kuwait and other organization.
- 4. EVALUATION PARAMETERS ? sodium absorption ratio (SAR) ? residual sodium carbonate (RSC) ? An indicator for sodium hazards (SSP) ? electrical conductivity (EC) ? calcium and potassium concentrations ? total suspended solids (TDS) ? trace metal analysis ? And other parameters of health significance.
- 5. CALCULATIONS
- 6. RESULTS Parameters Values Standards Acceptance Na 6.73 (meq/l) 8 (meq/l) Safe ( Ca + Mg ) / 2 2.19 (meq/l) 10 (meq/l) Safe SSP 59.265% 60% Safe SAR 4.55 13 Safe ESP 5.1723 15 Safe PH 6.66 None Safe Chloride potential 54.65% 20% Moderate Problems RSC -3.616 2.5 Safe BOD < 4.94 mg/l 10 (mg/l) Safe
- 7. CONCLUSION ? Excellent quality filtrate wastewater. ? Potential problems ? Chloride ? Trace metal ? MF treated wastewater is safe for irrigation in Kuwait.
- 9. What Is the Soil Aquifer Treatment ? A process in which long-term irrigation is used a method forTreatment ? Its used forTertiary treated waste water ? Showed a noticeable success in previous studies
- 10. Previous Studies According to Laboratory studies: 1-Under steady operating conditions it was proved that the process is working in improving the water quality 2-Lab analysis it was found that the Sulaibiya area was the most suitable for applying this process
- 11. Previous Studies According to Field Studies: 1- An improvement in the quality of water was noticed 2-Nitrate removal needed more improvement
- 12. Why (SAT) In Kuwait? 1-Kuwait is one of the countries that has low water supplies 2-High demand on reusing treated wastewater 3-The low cost of (SAT) Process
- 13. Objective of this study To Study the long term effect of (SAT) process on the quality of wastewater that is used for irrigation
- 14. Methodology ? Study Area: “The United Agricultural Production Company (UAPCO) Farm” that is located in Sulaibiya area of Kuwait was found to be the most suitable for the test according to the climate and the types of crops that is grown there ? Monitoring Wells: Eight wells were drilled in the UAPCO Farm to gather information on the groundwater characteristics and to observe the water quality withTime -A well were drilled in an in-irrigated area to provide information on water quality unaffected by irrigation
- 15. Results ? Water Level and Mound: The collected data showed the possibility of creating a water mound on the long term of irrigation (about 15m) in the middle of the farm ? Water Change Quality: The Chemical analyses of water indicated that the infiltrated water had lower Levels of (NO3 / PO4 / BOD/ COD)Than water used for irrigation. NO3 Content was higher due to nitrifications process TDS ContentWas higher due to soil leeching
- 16. Results ? The Following table Shows the efficiency of SAT test in improving water Quality
- 17. Conclusion ? The previous data and results shows the feasibility of SAT test in improving wastewater quality used in irrigation ? Making the treated wastewater available for unrestricted irrigation ? The effectiveness of the process in removing ammonia / iron / organic carbon and bacteria and BOD ? FurtherTests shall be introduced to assure the certainty of this process on the long term
- 18. HYDROGEN SULFIDE EMISSION ? The main objective of this paper is to study the emission rate of hydrogen sulfide (H2S) in Ardiyah SewageTreatment Plant in Kuwait (ATSP). ? The reason behind this study is : ? Citizens complaints – presence of undesired odor that may cause concern ? Workers complaints – various diseases that affected them and took too long to cure
- 19. ARDIYAH SEWAGE TREATMENT PLANT
- 20. HYDROGEN SULFIDE ? Hydrogen sulfide (H2S) is highly toxic with an unpleasant rotten eggs odor ? Easily detectable by smell ? Causes fire and explosion when it comes in contact with oxidizers and oxidizing material. ? The main source of emission of hydrogen sulfide into atmosphere is the presence of sulfide in wastewater at a low pH.
- 21. MODEL ? The Breeze ISC with ISCST3X PC version 3.2.3 ? This model is used for complex industrial areas and based on the Gaussian Theory ? 15 Sensors were put around the ASTP ? Sensors’ readings were collected to locate the maximum and minimum concentrations of H2S
- 22. RESULTS ? Three different scenarios are considered ? The highest concentration reached (6ppm) inside the plant ? Outside the plant the emissions were very low (nearly 0)
- 23. CONCLUSION ? No danger to the citizens outside the plant ? Main problem is caused from inside the plant Recommendations ? Tightly closing the inlet structure ? Supply equipment to the workers ? operate the ASTP at a lower flow rate than it is
- 24. Thank You
Editor's Notes
- #4: The main objective of this paper is to study the suitability of the secondary effluent wastewater from Kuwait wastewater plants, after treating it with a MF unit for irrigation purpose, without passing through a tertiary treatments. [The criteria used to evaluate the waste water quality to be use in agriculture are different by comparing the quality of MF product water with the standards for irrigation in Kuwait and other organization.] A MF unit was installed in the Riqqa wastewater treatment Plant, and samples were collected from MF unit, then sent to the laboratory as soon as possible. Comprehensive chemical and biological analysis was carried out to give a clear picture of the water quality.
- #5: These parameters are used to evaluate the quality of MF water Indicators for sodium hazard
- #6: Can be calculated using these equations
- #7: MF technique was succeeded in matching all irrigation requirements according the standards for irrigation in Kuwait and other organization.
- #8: it produced good quality filtrate water -According to results The Mf technique proved its reliabilities in rejecting most of the harmful constitutes of the treated wastewater. It produces an excellent quality filtrate wastewater that can be safely used in irrigation. Only chloride potential might causes a moderate potential problem. Although trace metal concentration was found less than standard concentration and is totally satisfied by MF filtrate water, it still that trace metals could be accumulated progressively in the soil though irrigation till it may exceed the crucial limits. Finally, there will be no dangerous hazards of using the MF product water in irrigation at Kuwait especially it will be used only for greenery.
