Abstract
Access to clean water remains a major challenge for the rural Ugandan communities
like Nakonge, where springs are the main water source. This study explores the use of
jackfruit (Artocarpus heterophyllus) seed powder and its lectin component as a
natural coagulant to treat contaminated spring water at the house hold level. Water
from Nakonge spring, Nsanja spring, and Bwanga community well showed high levels
of E. coli and coliforms. Exceeding WHO standards.
Physicochemical and microbiological tests during wet and dry seasons revealed serious
contamination, especially in Bwanga. Jackfruit seeds were processed into fine
powder, and jar tests were used to determine optimal dosage and performance
compared to alum. Results showed that jackfruit seed powder effectively reduced
turbidity and microbial counts, particularly with finer particles and proper
concentrations.
Lectins in the seeds also contribute antimicrobial action by disrupting microbial cells
and inhibiting bacterial communication. Though not perfect, the method improved
water quality significantly. This study highlights a sustainable, low-cost solution for
rural households and recommends further research into improving extraction methods
for even better results.
