Abstract The potential of zircon minerals in Indonesia, especially in Central Kalimantan, has not been adequately explored and developed into valuable materials with high technical and economic value and environmentally friendly. This research has the potential to be processed and formed into advanced materials, seeing its high potential as an excellent adsorbent for anions/cations in water treatment and industrial wastewater. This research aims to develop raw zircon minerals into zircon oxides, which will later be composited with magnetic nanoparticles. The zircon mineral processing is carried out using hydrothermal methods. It is known that the physical and mechanical characteristics are suitable to be developed by having good reusability and durability as advanced materials. The adsorbent characterizations of FTIR, SEM, and XRF analysis showed that the Fe3O4@ZrO2 had many different functional groups and a high specific surface area for adsorption processes. The Fe3O4@ZrO2 showed high adsorption uptake capacity and selectivity for the lead in the Sasirangan textiles wastewater. Therefore, the Fe3O4@ZrO2 have the potential to be used as an adsorbent in water and wastewater treatment.

Sorption Characteristics

In a number of water use schemes (water and wastewater treatment), physicochemical treatment methods, in particular adsorption, have been successfully used. However, widespread adoption of these methods is hindered by the high cost of sorbents. One of the promising solutions to these problem of sorption treatment is the use of biochar. Due to its high specific surface area, well-developed porous structure, and surface functionality, biochar has been used as inexpensive adsorbent. The purpose of the laboratory experiments is to determine the sorption properties of biochar obtained from pine – sorption capacity, sorption rate, and purification effect – while removing organic contaminants from real paper mill wastewater. The sorption properties of biochar were studied under static and dynamic conditions, varying the size of the fractions, and processing time. The sorption characteristics of biochar of all the studied fractions were established and it was shown that the most effective sorbent in removing organic contaminants is the 1-biochar’s fraction of (sorption capacity of 11.9 mg of COD per of sorbent). The data obtained enable theoretically substantiate the presence of certain functional groups on the surface of the researched biochar, as well as to develop technological regimes for the treatment of natural and waste waters of a certain composition with its help.

Life On Earth

Research aimed at solving important environmental problems at all scales ranging from global to individual will continue to be an essential part of the process by which sustainability of life on earth may be achieved. Solutions to environmental problems that relate to water are especially critical to this process and are likely to involve use of innovative technologies that emerge from research with sufficient promise to justify their development, a process that evaluates them at a scale that will yield engineering design parameters and confidence in their technical performance and economic value. Privatization of water and wastewater systems and mergers of equipment manufacturers may provide the economic bases needed for development of innovative water and wastewater treatment technologies in the 21st Century that have emerged from research in the 19th and 20th Centuries but have not as yet been fully developed or adopted.
