“…The corresponding C1s and N1s signals in the XPS spectrum of the PTL-pSBMA nanofilm further reflected the presence of a variety of functional groups, including amino, guanidyl, carboxyl, hydroxyl, and grafted pSBMA, on the film surface (Figure S21), which are responsible for the stable interfacial adhesion onto a variety of solid surfaces 43 . Second, the PTL-pSBMA nanofilm did not show notable changes in surface topography or film thickness (Figures S22-S24) after being subjected to stringent treatments, such as extreme pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11), organic solvents (dimethyl sulfoxide (DMSO), acetonitrile, petroleum ether, and ethyl acetate), adhesive tape peeling and even plasma irradiation, indicating the robustness of the PTL-pSBMA nanofilm under a wide range of external conditions.…”

“…For instance, the amount of surfactants reached 15.93 million tons in 2014, which is expected to increase to 24.19 million tons in 2022 1 . Among the numerous uses of surfactants, homecare detergents (e.g., laundry and kitchenware detergents) account for more than 40% of the global market [2][3][4][5][6][7][8][9] . As a result, the ever-increasing use of detergents has pressed the treatment of surfactant-containing wastewater to become a growing burden.…”

The extensive use of detergents in modern life and industry has seriously impeded ecologically sustainable development. Facing this unresolved global challenge, we herein propose a CAW (coating at will) concept to endow virtually arbitrary surfaces with underwater superoleophobicity that supports the fast and easy removal of oily stains by mere use of water. The key selling point of this CAW concept is its ability to sustainably regenerate the coating throughout an infinite life cycle. The foundation of this concept is to make use of rapid amyloid-like aggregation of lysozyme (Lyz) conjugated with zwitterionic poly(sulfobetaine methacrylate) (pSBMA). The resultant phase-transitioned Lyz-pSBMA (PTL-pSBMA) could quickly prime versatile surfaces to afford a robust colourless ultrathin nanofilm on surfaces with high hydrophilicity. As a result, the hydrophilic PTL-pSBMA layer endows materials with excellent underwater superoleophobicity and provides outstanding detergent-free cleaning efficiency to remove oily stains (e.g., greater than 95% on silk surfaces and 99% on dishes). With excellent optical transparency, biocompatibility and negligible effects on wearing comfort, the PTL-pSBMA further showed extraordinary cost-effectiveness ($ 675/ton) and great savings on water and energy by 40%-50%. Overall, this work proposes an ingenious CAW design that breaks down the long-standing surfactant contamination barriers in the traditional detergent industry. Such surfactant-free water washing strategy holds great promise towards scale-up application to replace commercial detergents in the removal of common stains from fabrics and kitchenware surfaces, thereby greatly inhibiting the negative environmental pressures caused by surfactant emissions and providing a transformative response to ecosystems and water resource protection on Earth.

“…Pathogens and heterotrophic bacteria must be controlled by an internal disinfection procedure in the aquaculture recirculation system. In a reusing water system, the effectiveness of Ozone alone and Ozone after which there should be UV radiation was tested to observe which was more effective in reducing heterotrophic and total coliform bacteria (Cao et al, 2021;Domingues et al, 2021;Giwa et al, 2021;Joseph et al, 2021;Lu et al, 2021;Mouele et al, 2021).…”

Over 70% of the planet's surface is covered by water. A universal solvent, water can dissolve a wide variety of compounds. The majority of water contamination is caused by human activity. Increasing water use and pollution are to blame for the current shortage of fresh water supplies. Population expansion, agricultural runoff, and municipal wastewater are the primary sources of pollution in the river. To conduct the study, the logical chain was developed. For the review, open sources of scientific information were used. The focus was on publications from the last 10 years and at the same time; earlier works were taken into accounts that have useful information for this study, which were identified in the list of references when studying recent sources. The number of sources published earlier than 10 years ago does not exceed 7% of the total number of references. The present study aims to determine the optimum conditions for best removal of contaminants as the review focuses on advancement in Ozonation/AOP technology, different type of methods used for drugs removal and different operating condition. Various modern treatment procedures make extensive use of drinking water treatment plants. Water shortages in countries can be alleviated by implementing some of the recommendations made in the research. More catchment areas need to be developed; strict management policies and guidelines should be implemented. Ozonation can also more effectively remove certain personal care products (PPCPs) from the skin. Recycled water can be disinfected using ozonation, which breaks down ozone in water. When ozone is used in this way, it is an effective parasiticide, germicide, and virucidal agent. It can also remove the chroma compounds, smells, infections, and many micro-pollutants simultaneously. Ozone-based AOP should be studied in the future to see whether it is cost-effective and to see if it consumes more energy than other traditional treatment methods.

“…Detergent removal from wastewater had been of concern in wastewater treatment in the past [3] and recently, in view of water scarcity, wastewater generated from laundry industry has become a potential source for water reclamation for reuse. Advanced oxidation process (AOP) using ozonation with combination of hydrogen peroxide was reported as an efficient way to treat detergent wastewater [4]. Combined biological and physicochemical treatment with UV/ozonation had also efficiently reduced the COD and completely removed the detergent from the laundry wastewater [5].…”

A Close Examination of the Detergent Destruction Method for Aerobic Treatment of Wastewater High in Detergent (WHD) Content

Detergent wastewater has to be treated to prevent water pollution, especially for the reclamation of large quantity of laundry waste water for reuse. A detergent destruction method removes detergent by using it to breakdown the activated sludge so as to prevent foaming when aerated in an SBR. Many research studies had reported methods and effects of increasing sludge reduction. A close examination of detergent destruction method to treat WHD has agreed well with the literature that activated sludge disintegration by consuming the detergent in waste water has significantly reduced the activated sludge amount by mixing with and without aeration. The high rate of sludge reduction with detergent destruction is comparable to sludge reduction with ultrasonic and other methods. This provides an economical and efficient way to breakdown sludge in improving the waste water treatment process.
