Comparative Assessment of Sludge Pre-Treatment Techniques to Enhance Sludge Dewaterability and Biogas Production
(Wiley, 2018)
Effectiveness of ultrasonication, microwave technologies, and enzyme addition prior to anaerobic digestion is investigated using sludge samples taken from the secondary settling tank of a domestic wastewater treatment plant ...
Photocatalytic activity based-optimization of TTIP thin films for E-coli inactivation: Effect of Mn and Cu dopants
(Elsevier, 2017)
Advanced oxidation processes (AOPs) are defined amongst the most effective treatment options for removal of micropollutants and bacteria inactivation. Among AOPs, photocatalysis process took particular attention of being ...
Visible light active N-doped TiO2 immobilized on polystyrene as efficient system for wastewater treatment
(Elsevier Science Sa, 2017)
The photocatalytic activity of N-doped TiO2 particles supported on polystyrene (PS) surface by using a solvent-cast method at ambient temperature was evaluated on methylene blue (MB) dye decolourization. Subsequently, the ...
An investigation of anthropogenic pollution in soil samples from residential areas in Erzincan city center and its vicinity by evaluating chemical factors
(Springer Heidelberg, 2018)
To measure heavy metal pollution, 42 different soil samples were collected and analyzed from the center, cities, and villages of Erzincan. Average element concentrations in the soil samples in micrograms per gram were as ...
Manganese adsorption by iron impregnated pumice composite
(Elsevier Science Bv, 2017)
Manganese (Mn) is often present at high concentrations in ground and surface waters. Industrial discharges are also a major source of Mn pollution in the environment. Adsorption is a widely studied technique to abate Mn ...
Assesment of Chemical Tretability of Fur-Suede Processing Wastewater Together with Toxicity Removal
(Yildiz Technical Univ, 2018)
The aim of this study was to assess the conventional coagulation/flocculation treatability efficiency and the toxicity effect of chemically treated effluent on Daphnia magna for fur-suede processing wastewater. Three ...
Memristor Based Sallen-Key Filters
(Gazi Univ, Fac Engineering Architecture, 2015)
In 1971, memristor is claimed as a missing circuit element and almost 40 years later than its prediction a memristive system behaving as a memristor has been found in 2008. Memristor is accepted by many as the new and the ...
Speech Coding System for Total Laryngectomees
(IEEE, 2014)
This work aims to obtain a signal processing method to neutralize the mechanical vibration sound from the electrolarynx which is used as a supporting device for speech restoration of people who have gone under resection ...
Performance Analysis of a Memristor - Based Biquad Filter Using a Dynamic Model
(Soc Microelectronics, Electron Components Materials-Midem, 2014)
New kinds of programmable amplifiers, adaptive filters, and programmable oscillators can be designed using a new fundamental circuit element memristor. Application of the memristor to analog filters can result in many new ...
Sigmoid Based PID Controller Implementation for Rotor Control
(IEEE, 2015)
This paper presents a sigmoid based variable coefficient PID (SBVC-PID) controller design for Twin Rotor MIMO System (TRMS). The proposed SBVC-PID controller dynamically changes controller coefficients according to a ...
