A Study on the Introduction of Artificial Intelligence Technology in the Water Treatment Process
Today, we stand in front of a huge wave of change named the "Fourth industrial revolution." Key technologies of the Fourth Industrial Revolution include artificial intelligence, the Internet of Thing (IoT), cloud computing, big data analysis, etc. These technologies will lead to an intelligent information society, and platform services will change every aspect of society from economic and work. This paper proposes several introductions of Artificial Intelligence Technology to improve water management.

Aerogel & Iron-Oxide Impregnated Granular Activated Carbon Media For Arsenic Removal
The goal of this project is to validate proof-of-concept testing for iron enriched granular activated carbon (GAC) composites (aerogel-GAC or iron-oxide impregnated) as a viable adsorbent for removing arsenic from groundwater and conduct technical and economic feasibility assessments for these innovative processes. Specific project objectives include: • Conduct batch experiments for aerogel-GAC and Fe-oxide impregnated GAC composites to evaluate their performance removing arsenic.
• Evaluate Fe-GAC media performance in rapid small scale column tests (RSSCTs) to assess arsenic removal in a more dynamic treatment system.
• Evaluate Fe-GAC potential for removal of other contaminants (e.g., methyl tertiary butyl ether, dissolved organic carbon).
• Characterize Fe-GAC media.
• Correlate performance and media characterization for possible selection of two media for a future second phase of this project.

Big Data Analysis For Studying Water Supply And Sanitation Coverage In Cities (Russia)
Big data analysis for water supply and sanitation is important for ensuring urban viability. Our research is devoted to studying the methodology for analyzing big data of the water supply and sanitation systems. Based on a review of scientific publications and their analysis, a model for analyzing large data was proposed. It comprises information sources, data collection and storage platforms with indication of parameters for the programming model, runtime and
storage environment, as well as data analysis and processing.

Removal of Aluminium from Drinking Water
Aluminium in drinking water comes from natural sources and the alum used as coagulant in the water treatment process. Exposure to aluminium has been implicated in dialysis dementia, Parkinson and Alzheimer’s disease. Drinking water containing aluminium was considered to be one of the main sources of Al intake into human body. For this reason, the removal of aluminium from drinking water is vital to our health. In this study, removal of aluminium was carried out by using a chelating resin.

Biofilm Control Study
Darigold operates a milk products facility in Lynden, Washington. Production processes include evaporation of milk, which generates what is referred to as condensate of whey (COW) water. COW water contains low molecular weight organic compounds including traces of lactic acid, alcohols, acetoin, and non-protein nitrogen (Möslang, 2017). COW water and non-contact cooling water from the Darigold Lynden facility are currently discharged to Outfall 001, which combines with stormwater and the City of Lynden’s wastewater treatment plant (WWTP) effluent discharge to the Nooksack River through the City’s outfall. Darigold’s discharge is regulated under National Pollutant Discharge Elimination System (NPDES) Permit No. WA0002470 administered by the Washington Department of Ecology (Ecology). In the future, Darigold’s COW Water and non-contact cooling water will be directly discharged to the Nooksack River in a new outfall pipe (Outfall 002) currently being constructed by the City.
