“…A typical application for GAC is as a substrate for biological media, in a treatment process known as biological activated carbon (BAC). Recent research has explored its benefits in a water treatment train following oxidation where a BAC stage enhanced the downstream performance of membrane filtration [36,37].…”

Storage of waste tyres causes serious environmental pollution and health issues, especially when they are left untreated in stockpiles and landfills. Waste tyres could be subjected to pyrolysis and activation in order to produce activated carbon, which is an effective adsorbent, and can find various applications, such as for wastewater treatment, removal of metals and dyes, energy storage devices, electrode materials, etc. Activated carbon (AC) is a non-polar and non-graphite material having high porosity and excellent adsorption capabilities, making it one of the most frequently used adsorbents in various industries. It is normally produced from carbon-rich materials such as coal, coconut shells, waste tyres, biowaste, etc. The use of waste tyres for the production of AC is a sustainable alternative to conventional sources (such as coconut shells and coal) as it supports the concept of a circular economy. Since AC sourced from waste tyres is a new area, this study reviews the methods for the preparation of AC, the types of activation, the forms of activated carbon, and the factors affecting the adsorption process. This study also reviews various applications of AC derived from waste tyres, with a specific focus on the removal of different pollutants from wastewater. Activated carbon derived from the waste tyres was found to be a versatile and economically viable carbon material, which can contribute towards safeguarding the environment and human health.

The study has been done in membrane production from the ratio of clay, zeolite and activated carbon. The goal of this study is to make membrane from clay, zeolite and activated carbon with micro particle size using Planetary Ball Milling Fritsch Pulverisette. The comparison of clay, zeolite and activated carbon is 80% : 10% : 10%, 70% : 20% : 10%, 60% : 30% : 10%, 50% : 40% : 10% with temperature combustion 600 °C, 700 °C dan 800 °C. Activated zeolite done with using HCl 2 M and then heated at 150 °C for 3 hours. Size particle from zeolite is 140 mesh with using Planetary Ball Milling Fritsch Pulverisette to reduce size of zeolite become 140 mesh with a rotation speed of 350 rpm for 6 hours. The result of this study shows that the highest flukes membrane found in clay, zeolit and activated membrane at 50%: 40%: 10% with temperature combustion at 800 °C around 4,859 L/jam.m2. The compressive strength on clay: zeolite: activated carbon ( 80%: 10%: 10%) with temperature burning at 600 °C around 39,6977 kg/cm2. Characterization testing using Scanning Electron Microscopy (SEM) on ceramic membranes with clay composition: zeolite: activated carbon = 50%: 40%: 10% at a combustion temperature of 600 °C obtained by membrane pore size of 2,699 μm. Adsorption with the optimum time obtained at 1 hour with a concentration of 0,2333 ppm. The highest effect of membrane composition on cation exchange capacity (CEC) is in the composition of 50%: 40%: 10% with a combustion temperature of 600 °C which is equal to 1.1 mgrek/g..

“…Ceramic membranes are used increasingly in water and wastewater treatment due to their inherent advantages over conventional polymeric membranes such as narrow and well-defined pore size distribution, high surface hydrophilicity, and good mechanical and chemical stability [ 1 ]. Although the capital cost for the application of ceramic membranes is still higher than polymeric membranes, the longer lifespan and the ability of ceramic membranes to pair with a wider range of pre-treatment approaches have made them an effective alternative technology to compensate for the higher cost [ 2 ]. However, membrane fouling due to the presence of naturally-occurring aquatic organic matter in source waters is a major challenge in the application/operation of both conventional polymeric and ceramic membranes [ 3 , 4 ].…”

Impact of the Interaction between Aquatic Humic Substances and Algal Organic Matter on the Fouling of a Ceramic Microfiltration Membrane

2018

The influence of the interaction between aquatic humic substances and the algal organic matter (AOM) derived from Microcystis aeruginosa on the fouling of a ceramic microfiltration (MF) membrane was studied. AOM alone resulted in a significantly greater flux decline compared with Suwannee River humic acid (HA), and fulvic acid (FA). The mixture of AOM with HA and FA exhibited a similar flux pattern as the AOM alone in the single-cycle filtration tests, indicating the flux decline may be predominantly controlled by the AOM in the early filtration cycles. The mixtures resulted in a marked increase in irreversible fouling resistance compared with all individual feed solutions. An increase in zeta potential was observed for the mixtures (becoming more negatively charged), which was in accordance with the increased reversible fouling resistance resulting from enhanced electrostatic repulsion between the organic compounds and the negatively-charged ceramic membrane. Dynamic light scattering (DLS) and size exclusion chromatography analyses showed an apparent increase in molecular size for the AOM-humics mixtures, and some UV-absorbing molecules in the humics appeared to participate in the formation of larger aggregates with the AOM, which led to greater extent of pore plugging and hence resulted in higher irreversible fouling resistance.
