When renewing water purification facilities, it is important to select a suitable purification system that can accommodate the quality of the respective source water. The Japan Water Research Center has been collecting a large amount of water quality data from drinking-water utilities across Japan, categorising and analysing these data, and evaluating the suitability of water purification processes. Multivariate analyses such as hierarchical cluster analysis and principal component analysis were performed to investigate the relationships between the quality of source water used for water supply and various factors that affect the purification process. Based on these results, water sources throughout Japan were clearly categorised into four groups, and suitable water purification systems were identified for the different water quality groups. The results can serve as an important reference for water utilities during future facility renewal projects.

Tank Water

The need for clean water is becoming urgent all over the world. The risk of microbial contamination of drinking water and its growing ability under poor nutritional conditions occur frequently and existing water management systems do not efficiently eliminate these micropollutants. The major goal of this research is to analyze and test the drinking water quality at random locations in Jeddah City and to investigate the integration of polyurethane foam coated nano-silica silver nanoparticles (NSAgNPs) into the water purification system. The study was conducted in Jeddah city at random intervals during August to December 2020. Twenty-five samples (n = 25) of drinking water (tank water) were collected from different locations in Jeddah. The water samples were found contaminated with E. coli, Klebsiella pneumoniae. and the most prevalent yeast species was Candida albicans. The multi-drug resistance isolates were positively identified by PCR amplification of 16S rDNA gene fragments. The antimicrobial activity of nano-silica silver nanoparticles (NSAgNP) was analyzed and their optimal concentrations that remove potentially harmful microbes were determined. The cytotoxicity of NSAgNPs by Sulforhodamine B colorimetric (SRB) assay against breast adenocarcinoma cell line (MCF-7) showed no cytotoxic effect at concentrations ≤100 µg/mL. The 50% growth inhibition concentration (IC 50) of NSAgNPs after 72 h was 35.8 µg/mL. The excellent performance of NSAgNPs can be attributed to the capping surface functional groups and smaller particle size 8.931 nm, as verified by TEM. In conclusion, the purified water obtained by using 100 mg/L NSAgNPs is free from microbial contaminants and completely safe to drink. We recommend the integration of biosynthesized foam coated silver nanoparticles with water purification system to achieve the desired final water quality.

Purification Methods

Для удаления остаточных количеств фармацевтических соединений, присутствующих в питьевой воде, на всех этапах водоподготовки могут применяться разнообразные способы очистки, основанные на различных физико-химических принципах. В работе приведены результаты экспериментального исследования эффективности удаления с помощью бытовой стационарной системы водоочистки остаточных количеств фармацевтических препаратов – антибиотика левомицетина (хлорамфеникола) и стероидного гормона эстрона – из модельного раствора, приготовленного на основе водопроводной воды с добавлением лекарственных препаратов. Показано, что бытовая система водоочистки обладает способностью существенно снижать остаточные концентрации фармацевтических препаратов левомицетина и эстрона на всем протяжении заявленного производителем ресурса. В секторе бытовой водоочистки установки адсорбционного типа по-прежнему остаются наиболее востребованным типом водоочистных систем, обеспечивающих высокую эффективность удаления различных загрязнителей при минимальных капитальных затратах. To remove residual amounts of pharmaceutical compounds present in drinking water, a variety of purification methods based on various physicochemical principles can be used at all stages of water treatment. The paper presents the results of an experimental study of the efficiency of removing residual concentrations of pharmaceuticals – laevomycetin antibiotic (chloramphenicol) and estrone steroid hormone – from a model solution prepared on the basis of tap water with the addition of drugs, using a home fixed water purification system. It is shown that the home water purification system provides for the significant reduction of residual concentrations of chloramphenicol and estrone throughout the service life declared by the manufacturer. In the household water purification sector, adsorption-type units are still the most in-demand type of water purification systems that provide for the high efficiency in removing various pollutants with minimal capital costs.
