Experiments were conducted during January 2009 at CSIR-Institute of Himalayan Bioresource Technology, Palampur, (HP) India to study the effect of light and temperature on seed germination of important medicinal and aromatic plants viz., Stevia rebaudiana, Salvia sclarea and Tagetes minuta in sand and filter paper. The treatments comprised of two factors viz., light and temperature regimes under...

High-Efficiency Oil–Water Filter In article number 2100594, Jiawei Hu, Yi Chen, and co-workers prepare a high-efficiency oil–water filter by coating sodium alginate hydrogel layer in the surface of porous sand core. This exhibits excellent separation ability toward mixed liquor emulsion. Moreover, it has chemical stability, easy cleanliness, strong durability. All these characteristics make thi...

This study presents a filter system for the removal of pathogenic microorganisms from potable water using silver nanoparticle-modified silica sand. While sand has potential applications in wastewater treatment, its effectiveness microbial filtration falls short. Thus, there is need an environmentally friendly enhancement method. The nanoparticles were synthesized Commelina maculata leaf extract...

BACKGROUND The aim of this study was to compare between slow and rapid sand filters for the removal of free-living amoebae during drinking water treatment production. METHODS Overall, 48 water samples were collected from two drinking water treatment plants having two different filtration systems (slow and rapid sand filters) and from inlet and outlet of each plant. Water samples were collecte...

Wastewater from the rubber industry that is not treated optimally can be one of causes environmental damage. Initial concentration COD waste liquid 711 mg/l and TSS 407 mg / l. Biosand Filter with activated carbon eliminate pathogenic bacteria by passing sand in filter will absorb organic substances. This study aims to determine effectiveness reduction, TSS, using a reactor BioSand dimensions u...

Two digging decapod crustaceans, the sand crab species Lepidopa benedicti and the mole crab species Emerita benedicti, both live in the swash zone of fine sand beaches. They were examined for two parasites that infect decapod crustaceans in the region, an unidentified nematode previously shown to infect L. benedicti, and cestode tapeworm larvae, Polypocephalus sp., previously shown to infect sh...

In this paper coarse media filtration has been analysed as an alternative to the traditional settling in primary, secondary and tertiary treatment of wastewater. Various filter media configurations were evaluated for enhanced primary filtration. It was found that a dual media configuration based on Kaldnes biofilm media (1 and K2modified) were most suitable when taking both separation efficienc...
