Reuse of wastewater for irrigation purposes

At present no Macrophyte WSP system under study in many of developing countries like Pakistan, so for promotion of macrophytes based WSP system, detailed pilot scale studies is needed for treating wastewater that can be used for irrigation purposes. In near future, water scarcity is expected all over the world so efforts should be made to address this issue, as most of economy of our country is dependent on agriculture. The aims of this study is to reduce and evaluate the different parameters of domestic wastewater by treating it with macrophtes WSP system with different Hydraulic Retention Times (HRT) so that wastewater can be used for irrigation purposes as per FAO Irrigation Water Quality Guidelines. A macrophytes WSP system model was designed /operated for five experimental runs with each run comprising of different HRT i.e. 3, 5, 7 and 10 days. For treating wastewater, locally available Macrophyte specie Duckweed was used. The different parameters used in this study were; ECw , TDS, SAR, Sodium, Chloride, Boron, Nitrate, Bicarbonate, pH and F Coliform. The average reduction in values of different parameters of wastewater at the start of each run was 31.96%, 31.96%, 42.51%, 31.00%, 22.86%, 34.52%, 30.23%, 50.23%, 20.02% and 41.39% for ECw, TDS, SAR, Sodium, Chloride, Boron, Nitrate, Bicarbonate, pH and F Caliform respectively. After treating wastewater with 10 days HRT, the values of different parameters of wastewater was within the range of FAO guidelines with slight to moderate degree of restriction on use.

Macrophytes and benthic macroinvertebrates, which play a functional role in hydrosystems, area also used as indicators of the quality of aquatic environments. The main objective of this study was to provide an initial overview of the diversity of macrophyte and benthic macroinvertebrate communities, associated with a number of abiotic variables in Parcours Vita Lake, located in the city of Douala in Cameroon. Overall, 24 species of macrophytes belonging to 18 families were recorded. The most represented family was Asteraceae with 03 species. The benthic macroinvertebrate communities were made up of the Arthropod (70.04%) and Mollusc (29.96%) phyla, grouping together 22 families, essentially from the Insect and Gastropod classes. The low values obtained for the Shannon and Weaver diversity indices reflected a major unevenness in the macrophyte and invertebrate communities at the various study stations. The Organic Pollution Index (OPI) revealed a high load of organic matter at station S2 (2.50). Similarly, the load was lower at stations S1 (2.75) and S3 (2.75), corresponding to a high level of organic pollution in the water at all three sites. This study has highlighted the threats to the functional dynamics of Parcours Vita Lake, which could compromise the sustainability of the current fish farming project and the development of an ecotourism activity.

ECOLOGICAL IMPACTS OF ECOHYDROLOGICAL INTERVENTION ON THE WETLANDS ALONG THE SOUTHEASTERN SHORE OF LAKE TANA, ETHIOPIA |  Journal of Global Ecology and Environment

Wetlands in the Lake Tana watershed are important for nutrient and sediment retention, biodiversity, and hydrological processes. Although ecohydrological remedies have been presented, there has been little research on the effects of ecohydrology intervention on biological issues. Information on the ecological consequences of an ecohydrology-based intervention method in the wetland environment is critical for boosting biodiversity and improving water quality. The goal of this research was to see how ecohydrological intervention affected macrophytes, phytoplankton, and zooplankton in the wetlands around Lake Tana's coast. Along vegetation and water depth gradients, quantitative features of macrophytes and plankton sampling were undertaken using the transect and quadrat methods. Each fixed sample site has its biological data measured. Phytoplankton, macrophytes, and zooplankton across the sample sites were substantially different (p0.05). Low-disturbed wetlands have more macrophytes, phytoplankton, and zooplankton variety and quantity than moderately and severely disturbed wetlands. The study's overall findings revealed that biological abundance and diversity were linked to the degree of wetlands degradation. As a result, the variables that may contribute to the deterioration of wetland resources within and around the watershed should be prioritised. To protect and avoid future deterioration of wetlands near Lake Tana's coast, immediate ecohydrology-based intervention techniques should be employed.
