ABSTRACT
The seeds of Moringa oleifera were tested as clearing and sedimentation agents in household water in Thaung Gyi Lay village with 110 households. Questionnaires were completed for each household and follow-up visits were carried out to ascertain the hypothetical acceptability (attitude), initial acceptability (behaviour) and experimental acceptability. It was observed that 78.9 per cent of the people accepted to use Moringa oleifera seeds if these were easily available. For continuous use of Moringa oleifera seeds, 47.3 per cent wanted to use, 44.7 per cent could not decide and only three households (2.7 per cent) did not want to use these. It was observed that the taste and pH of water did not change after treatment with Moringa oleifera seeds. There was no complaint about the treated water. This study will highlight the acceptance to use Moringa oleifera seeds for the sedimentation of turbid water.

The seeds of Moringa oleifera were tested as the clearing and sedimentation agents in tubid water from various sources (1) DMR pond (2) Yangon river (3) Bago River (4) Hline River (5) Hlinethaya Pond (6) artesian well from laydaunkkan and (7) Thanlyin River. the turbidity reduction of 80.00 to 99.5 percent paralled by a primary bacterial reduction of 90.00 to 99.99 per cent were obtained within the first one to two hours of treatment, the bacteria being concentrated in the coagulated sediment. It was observed that 100 mg (one ywe) of the seed powder served as a clearing agent in one litre of turbid water. However, the difference of clearing activity was not significant with different amounts of powder, lwhen 50 mg, 100 mg and 200 mg respectively were used with constant water quantity (one litre) within 24 hours. Moreover, the effect of the seeds could not alter the original pH of the tested water samples. The powder of M. oleifera leaves, bark and roots had no power to clear the turbidity of tested water samples.
