The decomposition of deposited CsI and iodine oxides (IOx) aerosols on sand bed a metallic filter has been pursued under irradiation at 120 °C. On the sand, it was found that are decomposed by temperature effect into an inorganic specie assumed to be molecular iodine. might due surface effects grains as usually stable this temperature. IOx expected well retained (DF > 100) long height is high e...

one of the main problems in micro irrigation system is inappropriate combination and in some cases inappropriate performance of filters and sand tanks in central control systems which cause reduction in efficiency of system and increasing of operating costs. this study evaluates affect the amount of algae on the performance of disc filters sand tank in research farm deputy of soil and water and...

Abstract Water pollution that occurs is mostly caused by industrial and domestic waste. One of the consequences polluted water increase in total N Phosphate which causes malfunction animals humans. This a problem needs attention to protect our life from dangers environmental pollution. Slow Sand Filter an easy inexpensive raw treatment solution. The used this research Dungus Sidoarjo river. acc...

abstract in order to investigate the removal of copper, nickel, zinc and chromium from industrial waste water by a sand–soil–organic matter filter column, this experiment was conducted at a completely randomized design with sixteen treatments and four replications. p.v.c tubes (columns) with 66.5 cm height and 10 cm diameter were chosen and filled from down to top by coarse gravel (15 cm), sand...

Some physical, chemical and biological properties of raw water collected from Caroni River in Central Trinidad and raw wastewater from Angostura Distillery in North Trinidad were measured in the laboratory. In addition, the properties of the water effluent obtained by passing the raw Caroni River water through various sand-clay filter media that differed in the proportions of sand and clay by v...
