In this study, the efficiency of household reverse-osmosis system (HROS) with and without neutralizer accessory was investigated in both real and synthetic samples. The real samples were collected from rural and urban public drinking-water systems with and without primary refinery treatment. The selected areas were situated in the Kurdistan province, Iran. The HROS model RO100GPD with and witho...

Abstract Background and purpose: According to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in Babol car factory, Iran. Materials and Methods: Physical and chemical par...

globally, irrigated agriculture is the largest extractor and the most frequent consumer of groundwater resources, with important groundwater-dependent and largely spread agro-economies. quality of irrigation water is one of the key factors which have either direct or indirect impact on plant growth, soil and water management practices and plant yields. this work aims at highlighting the importa...

In this work, we are modelling the physic-chemical parameters of water using bioindicator data (diatom taxa abundance data). Chemical status of the water (or water quality class) is defined by the values of measured physic-chemical parameters. Traditional approach to model these data is to learn a separate model for each parameter and then derive a global overview with some kind of summarizatio...

background: the chemical quality of water used for dialysis fluid is a vital factor in the overall care received by dialysis patients. therefore, water used for this purpose should be treated with advanced methods before use for dialysis. the objective of this study was to assess the efficiency of reverse osmosis systems to improve water quality used for dialysis fluid. methods: in this descrip...

Mafikeng, the capital of the North West Province, receives water from two sources, namely the Molopo eye and the Modimola dam. Once treated, the potable water is mixed and supplied to the city via distribution systems. This study was designed to assess the quality of drinking water in Mafikeng and also to determine whether the water from the two sources has an impact on the mixed water quality....

background: the presence of lead in natural waters has become an important issue around the world. lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. the aim of this work was to evaluate the adsorption of lead (pb(ii)) on waste tea leaves as a cheap purification method. methods: in this...

This paper presents the use of an equilibrium partitioning (EP) method to derive generic quality criteria. Quality criteria for dissolved concentrations in water, total water concentrations and total sediment concentrations were derived from direct-effect data (aquatic toxicity data) and product standard data (human consumption standards). Both sets of data were obtained from physico-chemical a...
