Published: September 2020

Abstract
In drinking water distribution system (DWDS), biofilm offers protection of bacterial community within the extracellular polymeric substance (EPS) from outside stressors, including surrounding environment, predatory microorganisms and antibiotics. The growth of biofilm may increase cleaning and maintenance cost for the drinking water decontamination and expose high risk to human immune system. This article critically reviews current Singapore DWDS by analysing the leading and lagging performance of two stages, granulated active carbon (GAC) filtering and secondary disinfection by chloramine, which are highly relevant with the biofilm resistance. Furthermore, other extrinsic factors, such as pipe age and material, hydraulic retention time, seasonal change, primary ultraviolet disinfection, etc. are also reviewed. Finally, top-down approach to address the growth and biofilm resistance are proposed. Practices and technology methodology, e.g. good consumers’ hygiene, nutrient removal, chlorine disinfection, probiotic approach, anti-biofouling coatings are discussed with their associated challenges and opportunities.

Authors: Liu Miao 
Published: September 2020

Abstract
More and more chromium (Cr) is being discharged into the environment, which is posing ecological risks to animals, plants and microorganisms, and endangering human health. Hexavalent Cr (VI) was more toxic than trivalent Cr (III), and the mobility of Cr (VI) in the water environment was higher than that of Cr (III). Therefore, various effective methods of reducing Cr (VI) were developed. In this research, the “biochar”, “chromium remediation”, were taken as keywords for patent retrieval. The retrieval time is from 1986 to 2019. A great number of patents about Cr (VI) remediation and biochar are collected and analysed applying big data. Based on the number and the legal status of patent applications, and the trend of patent applications, the research situation of biochar for Cr (VI) remediation in China is studied by S-curve law which is used to describe the technology life cycle theory in TRIZ theory. The results show that the technology of biochar for Cr remediation is still in its initial stage and full of potential.

Authors: Chen Peng 
Published: September 2020

Abstract
In order to reduce the emission of pollutants such as sulfur oxides and nitrogen oxides in ship exhaust gas, the principles and experimental methods of desulfurization and denitrification with low temperature plasma with dielectric barrier discharge were introduced in this study. The impacts of reactor voltage and reactor frequency of low temperature plasma, humidity and oxygen content of ship exhaust gas on the efficacy of desulfurization and denitrification were also explored by experiments in this study. It was revealed that the low temperature plasma technology could desulfurize and denitrify the ship exhaust gas better. The efficacy of desulfurization and denitrification would be increased when the voltage increases. At a voltage of 20 kV, the removal rates of NO and SO2 reached 59% and 52% respectively. When the reactor voltage was maintained at 15 kV, the removal rates of NO and SO2 would rise at the beginning and decrease later with increase of the frequency. The highest removal rates of NO and SO2 were 55% and 42% respectively when the frequency was 10 kHz. The efficacy of desulfurization and denitrification can be affected by humidity and oxygen content of the ship exhaust gas. Researches in this study provided a crucial reference for the application of low temperature plasma technology in the desulfurization and denitrification of ship exhaust gas.

Published: September 2020

Abstract
This study aims to explore the influencing factors of the Ag-based supported catalyst synthesized via hydrothermal synthesis method in formaldehyde catalytic oxidation treatment. CeO2 nanorods (CeO2-r) is prepared by hydrothermal synthesis method, and a series catalyst of Ag-K/CeO2-r with different concentrations of active components are prepared by adding active components to the nanorods by maceration method. The best weight hourly space velocity (WHSV), the best concentration of formaldehyde, and the best concentration of active components are studied with the prepared catalysts. When the WHSV is between 26000cm3(g h)-1 and 42000cm3(g h)-1, the maximum conversion rate is at the WHSV of 360003(g h)-1. The different formaldehyde concentrations are set, it is found that when the formaldehyde concentration is 300ppm, the conversion rate of formaldehyde through the catalyst can reach 100%. Under the condition of 300ppm, 360003(g h)-1, the optimal conversion rate of 4%Ag-K/CeO2-r catalyst is found to be the best at all temperatures. Moreover, the physical adsorption of the catalyst is related to whether the catalyst is loaded with auxiliary agent K. In this study, the Ag-based supported catalyst is prepared via hydrothermal synthesis method and the influencing factors of formaldehyde gas treatment are successfully investigated, which lay a solid foundation for further experiments.

Published: September 2020

Abstract
NaOH solutions with different concentration were used to pre-treat YPs (yellow pigments) in order to investigate surface modification effects on stability and particle size of pre-treated yellow pigments (PYPs). The coupling agent KH550 was used to treat PYP10 (yellow pigment pre-treated with 10% NaOH) to be compared for PYPs. The YPs (yellow pigments) were pre-treated by NaOH solutions and rinsed with C2H5OH, then the filtrates and residues were analysed by spectrophotometer and laser granularity analyser; The filtrates are stratified after the PYPs rinsed with C2H5OH. Microscope and Natural settling experiment were used to analyse the particle size and stability in residues. The results show that the particle size of wet PYPs decreased with the concentration of NaOH, and the particle size of PYP30 was smaller than that of PYP10-KH550 (PYP10 treated with 5% KH550). The laser granularity analyser results show that the particle size of dry PYPs increased with the concentration of NaOH. The settle time of PYPs in water indicated that the stability of PYPs increased with the concentration of NaOH and PYP10-KH550 has the poorest stability. These results indicated that PYP30 has smallest particles and best stability, and it has the potential to be used in industry.
