| Abstract | Due to unsustainable nutrient management, organic waste, wastewater and septage that
contained high concentration of nutrients discharged into surface water and onto soil
without prior treatment which causes large extent of environmental impacts.
The main objective of this study was to increase scientific lmowledge on the behavior of
material fluxes related to environmental sanitation by using method of Material Flux
Analysis (MF A) and to assess the possible mitigating measures aiming at optimizing
nutrients recovery in urban and peri-urban areas.
Pak Kret municipality with its agricultural area in Nonthaburi province was chosen as the
study area. The nitrogen fluxes in relation to organic waste and wastewater were chosen as
indicators. The processes defined in the system included peri-urban agriculture, markets,
household, on-site sanitation treatment, wastewater treatment plants, composting, and
collection and sorting process. The mass flows and nitrogen of all wastes were determined
tlu·ough the balancing of inputs and outputs of each process.
The results reveal that about 540 kg of nitrogen was disposed of daily in landfill in form of
organic solid waste. Additionally, about 1,000 tons per day of nitrogen in wastewater and
septage were discharged into groundwater and surface water and onto soil, likely causing
environmental impacts. The results also show that the key process contributing the organic
material fluxes was household, as characterized by a large turnover of materials and waste
production. Therefore, waste management measures taken at the household process could
enhance resource recovery and environmental protection in Pak Kret municipality.
This study proposed 3 mitigating measures to reduce environmental impacts and optimize
the nutrient recovery including construction of wastewater treatment plant , co-composting
solid waste and septage and central wastewater treatment plant together with composting
of solid wastes, most of which were reused the treated effluent and products to agricultural
areas. |
