Constructed Wetlands for Wastewater Treatment in Colombia

Autor: John Williams, J. E. Butler, D. Zambrano, M. G. Ford, Eric May

Publikováno v: Water Science and Technology. 40:217-223

A modular wastewater treatment system has been installed for the Colombian Coffee Growers Federation (FEDERACAFE) at the Fundacion Manuel Mejia residential training centre. This system was designed by the University of Portsmouth, UK, and based on pr

Nitrogen Transformations in Gravel Bed Hydroponic Beds Used as a Tertiary Treatment Stage for Sewage Effluents

Autor: Jane E. Butler, M. G. Ford, J. B. Williams, Eric May, John Williams

Publikováno v: Water Science and Technology. 29:29-36

The potential nitrogen transforming activities of bacteria were measured in the water and biofilms of a Gravel Bed Hydroponic (GBH) sewage treatment system. Within the GBH system, the organic matter and biofilms create complex partitioned micro-envir

Gravel Bed Hydroponic Systems Used for Secondary and Tertiary Treatment of Sewage Effluent

Autor: D. A. Bone, R. F. Ashworth, R. F. Loveridge, J. E. Butler, M. G. Ford

Publikováno v: Water and Environment Journal. 4:276-284

Gravel bed hydroponic (GBH) systems planted with emergent hydrophytes, such as Phragmites australis (the common reed), treat domestic sewage effluents to acceptable environmental standards in an economic and efficient manner. In temperate zones, such

Simultaneous prediction of aqueous solubility and octanol/water partition coefficient based on descriptors derived from molecular structure

Autor: D J, Livingstone, M G, Ford, J J, Huuskonen, D W, Salt

Publikováno v: Journal of computer-aided molecular design. 15(8)

It has been shown that water solubility and octanol/water partition coefficient for a large diverse set of compounds can be predicted simultaneously using molecular descriptors derived solely from a two dimensional representation of molecular structu

Mineralisation and pathogen removal in gravel bed hydroponic constructed wetlands for wastewater treatment

Autor: Magdi Bahgat, John Williams, Eric May, M. G. Ford, J. E. Butler

Publikováno v: Water Science and Technology. 32

Gravel Bed Hydroponics (GBH) is a constructed wetland system for sewage treatment which has proved effective for tertiary treatment in the UK and secondary treatment in Egypt. Significant improvements in effluent quality have been observed in 100 m l

CHEMICAL AND MICROBIOLOGICAL PROCESSES IN GRAVEL-BED HYDROPONIC (GBH) SYSTEMS FOR SEWAGE TREATMENT

Autor: R. F. Ashworth, M. G. Ford, E. May, J. E. Butler, M.M.M. Bahgat, John Williams

The gravel-bed hydroponic system (GBH) is an inclined, gravel-filled channel lined with an impermeable membrane and planted with helophytes such as Phragmites australis (the common reed). Such systems have considerable potential for the secondary and

Insecticidal activity of the pyrethrins and related compounds V. toxicity of the methylbenzyl chrysanthemates to houseflies (Musca domestica) and mustard beetles (Phaedon cochleariae)

Autor: Michael Elliott, P. H. Needham, Andrew W. Farnham, M. G. Ford, Norman F. Janes

Publikováno v: Pesticide Science. 3:25-28

The insecticidal activities to houseflies and to mustard beetles of the 19 methylbenzyl (±)‐cis‐trans‐chrysanthemates were measured to establish the patterns of substitution that produce the greatest toxicities to these insects. The two specie

Insecticidal activity of the pyrethrins and related compounds: III.-Penetration of pyrethroid insecticides into mustard beetles(Phaedon cochleariae)

Autor: Michael Elliott, M. G. Ford, Norman F. Janes

Publikováno v: Pesticide Science. 1:220-223

Substituted benzyl chrysanthemates are lost from the surface of Phaedon cochleariae Fab. at rates correlated with their toxicities to this insect, less toxic compounds in general being lost faster. The forms of the penetration curves are explained by
