In this analysis, different tools were utilized in measuring the different parameters, which were DO, temperature, pH, and turbidity. For the measurement of each parameter (with exception of turbidity) we dipped the parameter-stick about half-way into the water while swirling it slowly. We continued doing so until the monitor displayed a stable measurement for us to record. Turbidity was slight...
Due to their physical properties, illite clays can sorb cesium-137 almost irreversibly, and therefore sequester contamination from the environment. However, applying large amounts of clay to natural aquatic habitats for in situ remediation purposes may create conditions of high turbidity and sedimentation. To evaluate potential effects of turbidity from illite application on survivorship of str...
The various liver flocculation tests proposed in recent years by several investigators cannot be considered as specific, hence clinicians tend to use many of them simultaneously. Obviously, the simplicity and the rapidity with which any one of these tests can be performed are essential advantages. The following new liver function turbidity test is simple and rapid, and is more sensitive than th...
Seabed-hugging flows called turbidity currents are the volumetrically most important process transporting sediment across our planet and form its largest sediment accumulations. We seek to understand the internal structure and behavior of turbidity currents by reanalyzing the most detailed direct measurements yet of velocities and densities within oceanic turbidity currents, obtained from weekl...
colloids are small suspended particles in water which can not be settled or removed naturally due to their light weight and stability. these particles pose some degree of stability and cause water turbidity. there are some concerns regarding colloid removal efficiency in water treatment plants of iran. in this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluate...
Prediction method for large diatom appearance in winter with meteorological data and MODIS derived turbidity and chlorophyll-a in Ariake Bay Area in Japan is proposed. Mechanism for large diatom appearance in winter is discussed with the influencing factors, meteorological condition and in-situ data of turbidity, chlorophyll-a data with the measuring instruments equipped at the Saga University ...
Turbidity, which is caused by suspended chemical and biological particles, can have both water safety and aesthetic implications for drinking-water supplies. Turbidity itself does not always represent a direct risk to public health; however, it can indicate the presence of pathogenic microorganisms and be an effective indicator of hazardous events throughout the water supply system, from catchm...
Objectives : To recycle the wasted activated carbon from water purifiers and reuse stormwater runoff, this study evaluated quality of runoff with regeneration using granular containing commercial for treatment household purifiers.Methods The removal total coliforms, chloride, BOD, T-N, T-P, turbidity, pH in were analyzed by down-flow column test varied mixing ratios. In addition, chemical modif...
Introduction; Swimming pools are one of the important recreational places that due to direct relationship to different groups of people, can be a good carrier for bacterial, fungal and parasite diseases. This study was conducted to evaluate hygiene condition of the pools. Material and methods: In this descriptive study, all of active swimming pools of Bandar Abbas (based on Salvato recommendat...
In studies conducted in 2017-2020. It has been proved that the erosion and of Amu Darya's banks, which occur due to rapid uneven changes its channel, requires large expenditures for bringing water Amu-Bukhara channel with a damless intake. An analysis pumping station data shows uninterrupted movement system intake-distribution-channel-sediment retention system-system-fore-chamber-suction pipes-...
