“…According to statistical assessments performed for 37 companies in Egypt, about 50% of those companies release their effluents of wastewater, only some of which are treated, of approximately 1.3 billion cubic meters (BCM)/year into the public sewage system in violation of Egyptian environmental law [ 4 , 5 ]. This leads to the deterioration of the sewage network, especially because industrial effluent contains massive loads of toxic materials, which increases the cost and environmental risks of sludge treatment and disposal [ 6 , 7 ]. Therefore, industrial wastewater is considered one of the world’s most serious global environmental problems today.…”

The increase of global environmental restrictions concerning solid and liquid industrial waste, in addition to the problem of climate change, which leads to a shortage of clean water resources, has raised interest in developing alternative and eco-friendly technologies for recycling and reducing the amount of these wastes. This study aims to utilize Sulfuric acid solid residue (SASR), which is produced as a useless waste in the multi-processing of Egyptian boiler ash. A modified mixture of SASR and kaolin was used as the basic component for synthesizing cost-effective zeolite using the alkaline fusion-hydrothermal method for the removal of heavy metal ions from industrial wastewater. The factors affecting the synthesis of zeolite, including the fusion temperature and SASR: kaolin mixing ratios, were investigated. The synthesized zeolite was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), particle size analysis (PSD) and N2 adsorption-desorption. The SASR: kaolin weight ratio of 1:1.5 yields faujasite and sodalite zeolite with 85.21% crystallinity, which then shows the best composition and characteristics of the synthesized zeolite. The factors affecting the adsorption of Zn2+, Pb2+, Cu2+, and Cd2+ ions from wastewater on synthesized zeolite surfaces, including the effect of pH, adsorbent dosage, contact time, initial concentration, and temperature, have been investigated. The obtained results indicate that a pseudo-second-order kinetic model and Langmuir isotherm model describe the adsorption process. The maximum adsorption capacities of Zn2+, Pb2+, Cu2+, and Cd2+ ions onto zeolite at 20 °C were 12.025, 15.96, 12.247, and 16.17 mg·g−1, respectively. The main mechanisms controlling the removal of these metal ions from aqueous solution by synthesized zeolite were proposed to be either surface adsorption, precipitation, or ion exchange. The quality of the wastewater sample obtained from the Egyptian General Petroleum Corporation (Eastern Desert, Egypt) was highly improved using the synthesized zeolite and the content of heavy metal ions was significantly reduced, which enhances the utilization of the treated water in agriculture.

“…Disposal of industrial WW (raw or/ partially treated) into the existing Domestic WWTPs is a common practice in the industrial cities in Egypt such as: 10th of Ramadan city, New Nubaria city, and New Borg El Arab city (El Monayeri et.al. 9 , 2011). 10 th of Ramadan city is considered to be the largest industrial city in Egypt.…”

The addition of industrial WW to domestic WW should make a variation in its characteristics in terms of alkalinity, density and viscosity, TSS concentration and distribution, organic acid content, and heavy metals. This variation could affect the performance of primary settling tanks that received combined industrial and domestic WW. In the present study two different types of industrial WW were mixed with domestic WW in order to study the settling behaviors of combined WW by the aid of batch settling tests. Results showed that, at a RT range of (1.5 -2.5 hr), and a SLR range of (30 -50 m/d), the removal efficiency of TSS ranged between 56 and 72% for Domestic WW, from 44 to 56% for Industrial WW type A, and from 52 to 65% for Industrial WW type B. Industrial WW type A caused a decrease in TSS removal efficiency by 10% and 17% when mixed with domestic WW at mixing ratio 25% and 50% (industrial) respectively, while the industrial WW type B, showed no significant effect in TSS removal ratio when mixed with domestic WW. The flocculent settling velocities of the three types of wastewater could be calculated and compared.
