“…Cu 2+ , Pb 2+ and Cd 2+ are the common metals that tend to accumulate in organisms, causing numerous diseases (Ahali Abadeh & Irannajad, 2017;Buaisha et al, 2020;Salman et al, 2017). Several techniques such as adsorption, extraction, phytoextraction, ultrafiltration, reverse osmosis, electrodialysis, ion-exchange, and membrane processes are proposed for the handling of wastewater pollution and removing heavy metals from industrial wastewater required high energy or special operational requirements (Ayoub et al, 2016;Ebrahimi et al, 2014;Kwon et al, 2010). The selection of alternative low-cost materials such as sorbents for the removal of heavy metals has emphasized.…”

In this study, the adsorption behavior of Cu 2+ , Pb 2+ and Cd 2+ from synthetic metal solutions using natural zeolites was studied in order to investigate the efficiency of adsorbents of heavy metals from industrial wastewater. The kinetic study indicated the suitability of the zeolite for the removal of Cu 2+ , Pb 2+ and Cd 2+ ions from synthetic wastewater; batch experiments were used to identify the effect of parameters that affect the rate of adsorption such as the adsorbent mass, the initial solution concentration, the initial solution pH, the adsorbent particle size, and the agitation speed and evaluated their impact on the removal efficiency of heavy metals from industrial wastewater using the natural zeolite. Zeolite samples with masses between 1 g and 10 g were contacted with constant volume (100 ml) of multicomponent synthetic solutions containing Cu 2+ , Pb 2+ and Cd 2+ ions. They were agitated at agitation speeds in the range of 100-300 rpm for agitation times from 1 hr to 8 hrs in a magnetic stirrer at room temperature, the pH values were monitored and adjusted regularly. Every hour, 15 ml of the samples was analyzed using the Atomic Absorption Spectroscopy. The results show that the removal efficiency of Cu2 + increase from 60% for 1 gr to 99% for 10 gr of the mass of absorbent, increase from 62% for 1% to 94% for 7 of the initial solution pH, increase from 90% for 100 rpm to 94% for 300 rpm of the agitation speed, the amount

“…The raw primary sludge conversion resulted in the highest electricity generation capacity at 1.3 (MJ/kg dried), which was reduced to 0.8 (MJ/kg dried) in case digested sludge [11]. The biogas produced from anaerobic digestion of sewage sludge supplied to electricity generator saved 27% of electricity consumption of WWTP (2000 m 3 /d) instead of exporting energy from the main grid network [18]. The 15,000 tonnes sewage sludge anaerobic digestion plant produced the 7.3 m 3 biogas/PE at 20 MJ/m 3 generated the amount of electricity 2.6 MW.…”

Following the rapid growth of Malaysia’s population, the sewage sludge disposal capacity makes a big movement up to 7 million m3 annually. It proves that the conventional method, landfilling, causes negative issues related to the secondary pollution as well as high electricity consumption of sewage sludge treatment unit at 544,900 GWh in 2016-2019. The energy consumption also plays important role in the high fossil fuel-dependent energy production in Malaysia. The integration of energy conversion with sludge treatment is the potential method solving problems and global warming prevention. Thanks to the relative high heating value of sludge, the integration of energy conversion with sewage sludge treatment was suitable to reach two purpose including total waste destruction and energy generation through heat recovery, that results in the operating cost reduction and decrease of carbon footprint. The paper provided the overview of sewage sludge disposal and treatment status in Malaysia, it came with the potential of sludge treatment such as anaerobic digestion, combustion, gasification into useful energy was presented.

“…However, based on Geng et al (2007), sludge and primary sludge, including 20 % of the secondary sludge from a paper mill, were characterized as suitability for the producing of medium density fiberboard. On the other hand, Ayoub et al (2016) presented in their study that the sewage treatment plant can be used with reducing the capital costs by 26 % and running costs by about 20 %. The electricity can be produced from anaerobic digestion of sewage sludge as well.…”

The research presents an overview on sludge types, characteristics, and methods of treatment. Additionally, using the sludge as an energy source for future plans was studied as well. The paper focused mainly on analyzing different sludge characteristics based on the previous studies. Wastewater sludge produced from the primary, secondary, and tertiary treatment processes was analyzed. It was mainly composed of many organic and inorganic materials. Some of the materials were removed by physical and other required chemical or biological processes. Most of the sludge was solid, semi-solid, and muddy with the harmful substances such as proteins, phenols, and hazardous materials. The study explained different methods of energy production as well. At the end, it was concluded that every type of sludge could provide energy and be a basic financial product for the selected area, and keep environment safely and healthy as well. The calculated quantity of dry sludge for 1,000,000 inhabitants in Erbil City, Kurdistan Region-Iraq, was 50,000 kg/d, which produced calorific value of 9.5 · 107 K. cal./day. Furthermore, the essential area for under drain sand bed area was 5,100 m2 .
