“…It was concluded that flow rate is the key parameter in predicting the disinfection rate of pathogenic bacteria in drinking water treatment. Desmiarti et al (2018aDesmiarti et al ( , 2018b have also investigated the influence of flow rate on removal efficiency (RE), death yield and the death rate of bacteria when using an inductively coupled plasma system. Energy consumption was also calculated in their studies.…”

The impact of natural organic matter (NOM) and pathogenic bacteria in water are of great concern in water treatment due to their effect on human health. In this study, the ability to combine filtration with an inductively coupled plasma system (ICPS) to remove natural organic matter and pathogenic bacteria from water was investigated. UV260 adsorption, dissolved organic carbon (DOC) and excitation-emission matrices (EEMs) were used to evaluate the removal of NOM by the filtration-ICPS combination. The system was operated at two different flow rates, 100 and 150 ml/minute. Decreasing trend revealed for UV260 and DOC with the higher flow rate. Tryptophan-like substances generally found in water were taken as a measure of microbial activity. This preliminary research shows that the average removal efficiencies for fecal coliforms, total coliforms and salmonella were highest at a flow rate of 100 ml/minute. It can be concluded that the combined filtration-ICPS method is capable of removing NOM and pathogenic bacteria from water.

Nanoparticles represent a specific type of organic or inorganic matter with at least one dimension less than 100 nm and possess unique physical and chemical properties. The presence of nanoparticles in drinking water may pose a direct human health threat or an indirect risk through ingestion. Thus, the removal of nanoparticles from drinking water is needed. This research was carried out to study the distribution of nanoparticles in water treated with a combined filtration-inductively coupled plasma system by continuous processing. The flow rate was set at 100 and 200 mL/minute. The results showed that after 180 minutes of treatment, the amount and volume of nanoparticles in the treated water produced were different from those contained in raw water. The nanoparticles were within the diameter ranges from 2.70 to 6.50 nm and 0.62 to 712 nm for flow rate at 100 and 150 mL/minute, respectively. The particles within these diameter ranges belong to the group of proteins, small molecules and atoms. The measured zeta potential of the treated water had also decreased, indicating that the stability of the nanoparticles was reduced and removal by the combined filtration-inductively coupled plasma system had occurred. Further research is required to find the optimum flow rate and determine the exact components of the groups of nanoparticles.

The Sustainable Development Goals (SDG) 2015, which are defined to achieve improved and more sustainable future, promotes safe and affordable drinking water facilities for all, till 2030. The rural and remotely placed population worldwide face the problem of shortage of pathogen-free drinking water due to the huge capital and maintenance costs involved in water purification. The current chemical disinfection treatment which is widely used for water disinfection has several disadvantages including the formation of Disinfection By-Products (DBPs). Electro-chlorination is one of the best alternatives as per the literature that can be installed as a decentralized system in a remote location and can overcome most of the issues related to chemical disinfection. The present paper provides an overview of the innovations in the area of electro-chlorination as a disinfection technique through a detailed patent analysis. The patenting activity and publications are considered as an indicator of research and innovation in the field. The patent analysis is also supported by literature analysis for understanding the research trends and the extent of research in the area. The patent data from the year 2000 to 2021 is analyzed country-wise and year-wise. The paper also discusses the IPC, CPC codes, assignees, investors, US class codes, patents types, and citations analysis for the patents in the field of electro-chlorination and DBPs. The keywords used for patent analysis are ‘Electro- chlorination’ and ‘Water’ and ‘Disinfection’ and ‘Disinfection by Products’.
