Wrens Wintering in a Reed-bed

Reed bed characteristics and significance of reeds in landscape ecology

Reedswamps meet three important functions in landscape ecology: They act as a structural element and as a food-plant for a highly specialized fauna (species protection), the rhizomes stabilize the sediment and the stalks dissipate the wave energy (shore protection), and they improve the conditions for an enhanced microbial decomposition of an external organic load and an elimination or fIXation...

Exceeding tertiary standards with a pond/reed bed system in Norway.

At Vidaråsen in Norway sewage from a community consisting of 160 people, including a dairy, a food processing workshop, a bakery and a laundry is treated using a pond/reed bed system. The system consists of sludge settlement, pre-treatment surface/vertical-flow constructed wetlands, a 5 m deep enhanced facultative pond, three stabilization ponds, a planted sand filter and finally two horizontal...

Anti-sized reed bed system for animal wastewater treatment: a comparative study.

This paper presents a comparative study on the treatment of high-strength animal wastewater in two parallel lab-scale constructed reed bed systems, namely progressively-sized system and anti-sized system, which have same configuration but different arrangement of bed media. The reed bed systems were operated in a tidal flow pattern to treat diluted pig slurry. Detailed analyses were carried out...

Purification capacity of a highly loaded laboratory scale tidal flow reed bed system with effluent recirculation.

The purification capacity of a laboratory scale tidal flow reed bed system with final effluent recirculation at a ratio of 1:1 was investigated in this study. In particular, the four-stage reed bed system was heavily loaded with strong agricultural wastewater. Under the hydraulic and organic loading rates of 0.43 m3/m2.d and 1055 gCOD/m2.d, respectively, the average removal efficiencies obtaine...
