Abstract

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. The pH effect on adsorption were analyzed. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. Less acid the condition of the solution, the capability of the MgO/TiO2 catalyst on adsorbing the remazol turquoise blue dye will increasing. After 90 minutes, the photocatalysis rate surpass the adsorption rate and reach equilibrium.

Abstract

The rise of clinical activities is one of the health care facilities that have the potential to pollute wastewater on organic compounds and especially pathogenic microorganisms. Technology in reducing organic and pathogenic content using combined ultraviolet filtration in wastewater treatment systems is one the effective method. Filtration uses activated carbon and silica with a variation of the ratio 2:3 and 3:2, while ultraviolet use a power variation of 9 watts and 15 watts. The results obtained are the best composition from the filtration process, which is a ratio of 2: 3 with the ultraviolet process using 15 watts using an exposure time of 5 hours with the remaining total coliform as much as 200 MPN/100mL. The results of this research have complied with the quality standards.
