Temporal Patterns of Quality Surface Water Changes

The study spatial and temporal changes of water quality in Choghakhor wetland using water quality index (WQI)

In order to investigation of water quality of the Choghakhor wetland by use of WQI, ten stations were selected. Sampling was done every 45 days since April 2010 until March 2011 with 3 replications at each station. Water Quality Index (WQI) was calculated using nine water quality parameters (Nitrate, Nitrite, Alkalinity, Hardness, Turbidity, Conductivity, Dissolved Oxygen, pH and Biochemical Ox...

Spatio-temporal changes of water quality variables in a highly disturbed river

Quality of river varies widely depending on the land use in the catchment and environmental factors. Many rivers in developing countries are unhealthy because they contain harmful physical, chemical and biological agents. Zanjanrud River, located in Zanjan Province, Iran, where recently faced human intervention needs a regular monitoring from upstream to downstream for sustainable management. H...

Changes in Water Quality Parameters in Different Processes of Surface Water Treatment Plant (Case study: Tehranpars Water Treatment Plant)

  Background and purpose: Water treatment is of great importance in human life, due to the contamination of water resources. Therefore, continuous evaluation of the performance of water treatment plants is necessary to minimize contamination within the treatment plant in order to create optimal conditions. Materials and methods: A cross-sectional descriptive analytic study was performed in Te...
