Fe2O3-sepiolite was used as a catalyst in the heterogeneous Fenton/photo-Fenton processes. Among the processes studied, heterogeneous photo-Fenton process showed highest colour...

In the present study, coupling electro-Fenton (EF) and adsorption processes for textile industry wastewater remediation was investigated, in both batch and continuous flow modes. Sepiolite was used as an adsorbent in the coupled EF/adsorption processes. Various parameters such as reaction time, current intensity, Fe²⁺ concentration, sepiolite dose,...

Sea water intrusion into the groundwater is considered as important environmental issue for the coastal aquifers in Turkey. This research used an experimental analysis method and focused on the assessment of aquifer water quality due to sea water intrusion in the delta coastal area of Kızılırmak River, which is the third longest river, in Turkey, l...

In the present study, hybrid prediction models were used to estimate the adsorption of ammonium from landfill leachate by using zeolite in batch and column systems. The effects of initial ammonium concentration, mixing speed, and particle size in batch experiments were while the effects of flow rate and zeolite particle size were determined as inde...

In this study, multilayer perceptron (MLP) artificial neural network was used to predict the adsorption rate of ammonium on zeolite. pH, inlet ammonium concentration, contact time, temperature, dosage of adsorbent, agitation speed, and particle size in the batch experiments were used as independent variables while flow rate and particle size in col...

In the present work, sepiolite clay was assessed as an adsorbent for the removal of cationic (Methylene Blue: MB) and anionic (Direct Red-23: DR-23) dyes from aqueous media. Firstly, the sepiolite clay mineral was characterized using different instrumental techniques viz., XRD, SEM, EDX, FTIR, X-ray Fluorescence, and BET analysis. Thereafter, the a...

In this study treatment of zinc plating wastewater by combination of electrocoagulation (EC) and ultrafiltration (UF) process was investigated. The effect of operating parameters such as wastewater pH, flow rate and membrane pore size on zinc removal was investigated to optimize EC-UF process. The results showed that zinc removal was pH dependent a...

Most of the major cities in our country are opposed to the problem of water pollution due to the uncontrolled leachate resulting from the decomposition of solid wastes in irregular landfills. The waste waters that have high nitrogen content such as leachate cause various problems like eutrophication. In this study; the preliminary treatment of leac...
