  Low-cost filtering materials for domestic water treatment

  Year: 2024

  Collections: Scientific Publications

  Topics: Water

  Authors: Nematullah Fetrat, Ahmad Reza Rostayee, Sai Kala

  Countries: Afghanistan

  Source: https://water-ca.org

  The article investigates certain low-cost filtering materials and their filtration efficiency for open well sources in terms of economic access to clean water in Anakapalle, a suburb of Visa-khapatnam, India, during the pre-monsoon period of 2022. The corresponding research aimed to study a selection of filter materials including coconut shell activated carbon, rice husk ash, manganese modified sand, and graphene oxide, as well as assess their performance against selected physico-chemical parameters of water. Considering the basic idea of slow sand and gravity-based filtration, a setup was arranged with a cartridge filled with layers of filtering materials and a ceramic candle filter. Adsorption turned out the most pronounced removal mechanism that took place when utilizing the aforementioned filter materials. The main focus of the study was to reduce pH, TDS, hardness, alkalinity, chlorides and iron content by applying dif-ferent filtration removal mechanisms. The study results show a significant drop in turbidity, pH, TDS and chlorides, and small reduction in hardness when coconut shell activated carbon and rice husk ash were used as filtration media. Whereas the chemically coated medium – manga-nese modified sand – demonstrated a considerable fall in iron concentrations, graphene oxide sand was observed to reduce alkalinity for any sample source.

  Water Tales from Turkistan: Challenges and Opportunities for the Badam-Sayram Water System under a Changing Climate

  Year: 2024

  Collections: Scientific Publications

  Topics: Water, Climate

  The Badam River, a tributary to the Arys River located in the Syr Darya basin, is a crucial natural resource for ecological, social, and economic activities in the semi-arid region of southern Kazakhstan. The river basin is heavily influenced by manmade water infrastructure and faces water scarcity, particularly during summer, highlighting the importance of understanding its hydrological processes for effective water resource management. In this study, a semi-distributed conceptual hydrological model of the Badam River was implemented using the RS MINERVE hydrological software to evaluate the impacts of climate change on hydrology and to test the resilience of the water system. Connected HBV models were implemented for each of the hydrological response units that were defined as altitudinal zones. The hydrological model was calibrated using daily time steps between 1979 and 2011, and the resulting flow exceedance curves and hydrographs were used to assess the potential impacts of climate change on the basin, using CMIP6 precipitation and temperature scenarios. Future climate scenarios for the 2054 – 2064 period demonstrate that the peak discharge will be shifted to spring/late spring compared to the current early summer with no significant decrease in average discharge per day of the year. The insights gained from this hydrological-hydraulic model can be used to effectively manage the water system and inform future hydropower design decisions and serve as a blueprint for similar studies in the region and elsewhere.
