Moringa oleifera Presentation Transcript

  • 1. Moringa oleifera – Household Alternative Coagulant for Water Treatment. Presented BY Majithiya H. M . Email: hmajithiya@gmail.com
  • 2. Introduction  Coagulation-flocculation followed by sedimentation, filtration and disinfection, often by chlorine, is used worldwide in the water treatment industry before the distribution of treated water to consumers (Peavy 1995).  However recent studies have pointed out several serious drawbacks of using Aluminium salts.

  • 3. Introduction about Moringa oleifera M. oleifera pods M.O shelled seed Shelled seed M.O Press Cake •It tropical plant belonging to the family Moringaceae . •Seeds are brown, and the kernels are white Crushed whole seed or presscake remaining after oil extraction as a coagulant for water and wastewater treatment. 3 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 4. Purpose of study  In situation where high concentrations of alum are needed, lime is also added to raise the pH of water, thereby facilitating the treatment.  The cost of procuring these chemicals is increasing rapidly and most developing countries are finding it difficult to cope.  Therefore, where cheaper alternatives can be found, to replace or supplement the conventional treatment chemicals, their use would be a welcome benefit for the poorer less developed countries. 4 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 5. Natural Coagulant Vs Inorganic Coagulant Drawbacks of Alum -  Alzhemeiers disease and similar health related problems associated with residual aluminum in treated water.  It produces large sludge volumes.  It require pH Alkalinity adjustment.  Low efficiency in coagulation of cold water.  It is costly and require high foreign exchange. 5 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 6. Advantage of Moringa oleifera Coagulant over Alum  It is natural, completely non-toxic.  The M. Oleifera seed extract appears to have natural buffering capacity so, no pH alkalinity adjustments are required.  Beside level of turbidity it reduces the level of microorganism in water.  It is completely biodegradable.  The volume of sludge produced is considerably less in case of Moringa than in case of alum. 6 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 7. Drawbacks of Moringa oleifera  At present availability of seeds is a problem it require mass cultivation.  The costs of the Shelled Seed powder of M.O will probably higher then the cost of alum at present.  The water treated by M. oleifera produces odour after two days from treatment.  Another disadvantage water extract increases Dissolved Organic Carbon in treated water. 7 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 8. Aim & Objectives Aim Optimization of dosage Affecting Coagulation and Flocculation of Turbid Water Using Moringa oleifera Seed Extract Objectives  To optimize coagulation dose, slow and rapid mixing parameters.  To improve the extraction method of coagulation active component.  To study Household Alternative Coagulant for Water Treatment. 8 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations

  • 21. Conclusions  Moringa oleifera seeds present a viable alternative to alum.  Increase dosage of Moringa oleifera lead to decrease turbidity upto the optimum dosage after which the residual turbidity increases due to floc restabilization Increasing initial turbidity, optimum dose is subsequently found to increase.  Requirement dose for Moringa oleifera for both Shelled blended and shelled blended oil extracted was higher than alum all over the turbidities range from 50- 450 NTU. 21 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 22.  The oil content in the seed will form an emulsion or film coating which may inhibit the contact with the surface of reaction and thus reduce floc formation. Shelled blend oil extracted Moringa oleifera has been found to be more effective than the shelled blended seeds as a primary coagulant for turbid water.  It is easy to prepare the suspension and can be use as household water treatment.
  • 23.  M. oleifera seed contains 40 % oil by weight & hence after oil extraction waste product “presscake” contain active component affecting coagulation in water treatment, therefore farmers can promote for cultivation.  Using M. oleifera as a replacement coagulant for proprietary coagulants meets the meets the needs for water technology in developing countries which is simple to use, robust and cheap to both install and maintain sustainable as household coagulant. 23 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
  • 24.  Moringa oleifera is a consumer friendly and environment friendly low alternative for rural areas or small scale water treatment plant. M. oleifera is a renewable resource can be grown on large scale.  Research should therefore continue in this area so as to apply it to small and large scale water treatment in tropical development countries. 24 Introduction Aim & Methodology Materials Observations & Conclusions Suggestions & Objectives & Methods Data Interpretation Recommendations
