To overcome the water pollution problems, and to meet stringent environmental regulations, scientist and researchers have been focusing on the development of new water purification processes. One such group of new technologies is advanced oxidation processes (AOPs). Among the AOPs, titanium dioxide photocatalysis has been widely studied on lab scale by the researchers for decontamination of drinking water. In the present chapter, a conceptual as well as state-of-art review of titanium dioxide photocatalysis for water purification has been discussed.

Clean Drinking Water

The aim of this project is to develop a low-cost water purification system that provides clean drinking water. The project has a broad reach since drinking water pollution is a big global problem. This device would provide a solution to contaminated drinking water. Electric current is used to power the purifier during the water treatment process, reducing fluoride, chloride, and increasing the pH content of salty water, resulting in potable drinking water. To achieve this aim, a project management plan has been devised that divides the tasks amongst the community. The ultimate goal of designing this project is to provide clean drinking water at a low cost. The aim of this project is to develop and build a small-scale water purification system that needs little maintenance and is inexpensive. Initially, solar power would be used to power the purification system and to transition the system to renewable energy.

Water Borne

In India, water borne diseases are increasing day by day. Nearly, 60% of India’s population has to drink unsafe or impure drinking water. Drinking impure water gives rise to many water borne diseases such as diarrhea, typhoid, etc. Energy crisis is another big issue in our country as India is a developing country. Conventional energy sources are limited and they cause environmental pollution. By using a renewable energy source such as solar power for water purification, we can avoid above mentioned issues as it gives solution to both the problems. Solar water purifiers comes up with a solution to these problem as water gets purified with the help of solar energy. Solar water purifiers are an advancement of the current water purification system. Design methodology of the solar water purifier is presented in this paper. Solar water purifier takes solar power as the input and uses it as a energy source and stores it into the battery. Main components of the proposed solar water purifier are solar panel, battery, heating coil, filtering mechanism, double layer condenser and several water vessels. This purifier uses a filtering mechanism to remove dirt from the impure water and a boiling mechanism to kill organisms present in it. Through this process, pure drinking water is achieved.

Volatile Halocarbon

A commercially available water purification system was evaluated for its ability to minimize chemical and microbial contaminants. The reduction or removal of these impurities from the drinking water of experimental animals would reduce experimental variability. 3 strains of bacteria were collected from the processed water. An increase in the total number of bacteria was observed the longer the filters remained in use. Determinations of heavy metals in water samples before and after processing were made for lead, zinc, copper, nickel, manganese, iron, arsenic and mercury. Calcium and magnesium levels were also determined. The concentrations of these inorganic chemicals were reduced by the purification process except at 2 time points in which desorption of the chemical could have occurred. Bacterial colonization and desorption of these chemicals were controlled by installing new filter cartridges. Volatile halocarbon concentrations were determined for water samples before and after purification. All volatile halocarbons analyzed were less than 10 ppb before and after purification at all time points. Other organic chemicals were greatly reduced by the purification process. In a study of contaminants associated with installation of the unit, it was found that flushing the unit for 8 days reduced lead and methyl ethyl ketone concentrations to insignificant levels. The purification system was found to be effective in providing high quality drinking water as verified by a microbial and chemical testing program.

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.
