Abstract

Four distinctive Ceramic membranes have been synthesized using bentonite and Egyptian clay with the expansion of melamine. The addition of melamine (~ 1% by wt.) enhanced the porosity, density, the thermal stability and water permeability of the membranes made from bentonite or Egyptian clay while decreasing the chemical stability of either bentonite or Egyptian clay membranes. The most noteworthy level of decrease in COD (94.7%) is acquired for the concentration of 200ppm with saturating flux of 4.63 E-05 (m3/m2.s) utilizing (B+M) membrane. The cost of the four manufactured clay membranes was assessed based on raw materials used in the present investigation.

Highlights

Wastewaters are one of the significant contaminants of the aquatic environment
Bentonite; the EDAX analysis for bentonite is presented in Table 1, Egyptian Clay collected from Behaira Governorate area; the EDAX analysis for Egyptian clay is presented in Table 1, sodium carbonate, calcium carbonate, boric acid, sodium metasilicate and melamine as raw materials
The acquired pores were associated with one another. This clarifies the growth of the permeability for either bentonite with melamine membrane (B+M) or Egyptian clay with melamine membrane (C+M)

Summary

Introduction

Wastewaters are one of the significant contaminants of the aquatic environment. Wastewater emitted to the aquatic environment is ranging from 0.5 to 1 ton for every 1 ton of processed oil from refineries [1]. Consistently somewhere around 500 to 1000 million ton of oil is released into the aquatic environment through different ways [2], which causes water contamination, as well as ends up being a misuse of oil assets. Membrane separation technology for oily wastewater treatment offers numerous advantages with respect to other strategies, for instance, small footprint, low cost for establishing or operating and high oil removal efficiency [11, 12]
