Performance evaluation of filtration and ultrafiltration for municipal secondary effluent reuse


Amir Hessam Hassani et al. View all

Water and Wastewater Treatment

This study aimed to evaluate the performance of microscreen drum filter and ultrafiltration (UF) as a ‎tertiary treatment to improve the secondary effluent quality. Additionally, hydraulic loading of ‎drum filter and membrane flux of UF were changed. On average, the use of drum filter and UF...

Non-thermal plasma-assisted growth of ZnWO4 hierarchical nanostructures: morphology, structure and photoactivity


Hadi Fallah Moafi et al. View all


Zinc tungstate (ZnWO4) photocatalyst was synthesized by precipitation method and treated with different non-thermal plasma to study its morphology, structure and photocatalytic activity. The X-ray diffraction results revealed that the plasma-treated ZnWO4 exhibited only wolframite structure and its...

Experimental investigation on light weight cellular concrete using recycled glass and plastic waste


Sagaya Albert. A et al. View all

Solid Waste Management

Cellular Lightweight Concrete (CLC) also known as Foamed concrete is one of the most significant type of concrete used for construction purposes due to its various advantages and usages over traditionally produced concrete. The rapid urbanization has led to the enormous increase in wastes being...

Multivariate Extension of the Singular Spectrum Analysis A New Tool in Understanding the Intraseasonal-Oscillation (ISO) of Philippines Summer Monsoon and its Association with Extreme Rainfall Events


WARREN I. LUZANO et al. View all

Global Environmental Change

The intraseasonal low-frequency oscillation is studied by using gridded rainfall dataset from 1979 to present. Multivariate Singular Spectrum Analysis (SSA) was used in the extraction of these modes. We have found out that there is a significant increasing trend in the relative strength of low...

Synthesis of 1,5-diphenylcarbazide-immobilized alginate/pectin films for colorimetric detection of Cr(VI)


Dwi Siswanta et al. View all

Water Quality

An optical sensor for colorimetric detection of Cr(VI) has been synthesized by immobilizing 1,5-diphenylcarbazide (DPC) into alginate/pectin films. The addition of cationic surfactant (CTAB) was used to increase the effectiveness of DPC immobilization by forming hydrophobic-ion pairs. At optimum...

The Optimal Porosity of Shelterbelts in an Oasis–Desert Ecotone in the Junggar Basin, Xinjiang, China


Tong Liu et al. View all


Wind erosion is mainly a phenomenon of arid and semiarid areas, and the porosity of shelterbelts is an important quantitative index for estimating windbreak structure. However, there appears to be considerable variation in the optimal degree of porosity. With the example of an oasis–desert ecotone...

Consumers’ Eco-product Purchase Decision-Making Behavior from the Perspective of Ecological Awareness


Junli Zhang et al. View all


In this study, an ecological awareness rating scale and an eco-product purchase decision-making rating scale were developed based on literature and interviews with experts. The ecological awareness variables were subdivided into three aspects: ecological knowledge, ecological emotion, and ecological...
