Abstract
In recent decades, research concerning and knowledge about the external benefits of renewable raw materials have intensified the efforts for investigating the major sources, causes, and effects of wastewater from solid waste and industries or households. In this study bio-matter and low-cost photocatalyst was prepared for photodegradation on the removal of methylene blue from wastewater treatment, and characterized by Fourier-transform infrared (FTIR) spectroscopy, UV-spectrometer, and X-ray diffractometer (XRD). The effects of initial concentration of methylene blue, amount of dopant, and degradation time were investigated on the percentage degradation of methylene blue using the calcinated eggshell doped titanium dioxide nanoparticle catalysts. At sufficient contact time and low initial concentration, the increment in dopant dose from 0.5 to 2.5 g/l results in an increment of methylene blue degradation efficiency, from 52.5 % to 95.8%. It was shown that a calcinating eggshell doped titanium dioxide photocatalyst method for wastewater treatment is a promising option for the degradation of methylene blue from industrial wastewater under the stated condition.

A day the health problem connected with water pollution is the major and primary issue throughout the world (Raizada et al, 2020)
The photocatalyst of Calcined Egg Shells (CES) doped titanium dioxide was characterized by Fourier-transform infrared (FTIR), X-ray diffractometer (XRD), and UV-vis Spectroscopy analysis for determination of their functional group, structure, and bandgap energy respectively
In this study CES doped titanium dioxide was investigated for degradation of methylene blue compound from industrial wastewater
Summary
A day the health problem connected with water pollution is the major and primary issue throughout the world (Raizada et al, 2020). The focal sources of wastewater is derived from a weak controlling mechanism of wastes from the industry plus from humans, animals, household, laundry and faesal sludge might be due to the lack of treatment services, or the fact that the existing facilities are not functioning as intended (Review et al, 2020). Usage of this untreated wastewater in agricultural activities are led to risk for both farmers in contact with water and crop consumers through transfer of pathogenic organisms (microbes that cause disease) from water to crop. Effort should be made towards providing a wastewater treatment option for these industries to allow environmentally friendly disposal of their wastewater that reaches specific effluent quality goals
