Ecological and economical balance for sludge management options

Jeremy Hall WRc plc, Medmenham, Marlow, SL7 2HD, United Kingdom


The treatment and disposal of sewage sludge is an expensive and environmentally sensitive problem. It is also a growing problem world-wide since sludge production will continue to increase as new sewage treatment works are built and environmental quality standards become more stringent. With some traditional disposal routes coming under pressure, and others such as sea disposal having been phased out, the challenge facing sludge managers is to find cost-effective and innovative solutions whilst responding to environmental, regulatory and public pressures. Recycling and use of wastes are the preferred options for sustainable development, rather than incineration or landfilling, but with sewage sludge this is not straight forward because of perceptions over contaminants, pathogens and its faecal origin, particularly by the food retailers. If future quality standards for sludge and the receiving environment are made too stringent, the agricultural outlet may become untenable for the water utilities resulting in sludge being disposed of by other means that offer the utilities greater operational and financial security, but which may be less acceptable in the long-term. This paper discusses some of the issues relevant to achieving a practicable and affordable balance in sustainable sludge management.

    Bonjour 

    Il n'existe aucune technique novatrice dans le traitement des boues car en -biologie- la boue est une matière organique morte.

    Toute matière organique -Vivante- dont la circualtion de VIE cesse voit MERE NATURE enclencher le processus de son élimination automatique.

    Mais la boue d'excréments sort totalement de tout processus naturel. C'est une matière organique d'un type spécifique qui a été sorti de son contexte d'élimination naturelle. En plus c'est une matière organique qui est passée de l'ETAT de Vivant en boue puis en boue putride.

    On pourra chercher par tous le moyens que nous disposons pour tenter de l'éliminer, c'est impossible.

    La boue d'excréments est un poison popur l'environnement et la disperser dans l'environnement est un crime contre l'humanité.

    En effet cette boue d'excréments est imprégnée de multiples composants chimiques.

    Incinérée elle génère des REFIUM et pollue l'atmopshére que nous respirons 

    Epandue en terre agricole elle contamine notre base alimentaire

    Déversée dans nos milieux hydrauliques naturels elle contamine toute la faune et la flore aquatique   

    La meilleure attitude pour ce genre de problématique c'est de ne pas produire de résidus de boue.

    Hors on est très loin de régler ce probléme parce que toutes les installations de gestion des effluents d'eaux usées ne sont là que pour produire plus de 45 millions de tonnes de boue d'excréments.

    Je dis gestion car effectivement la tromperie du mot épuration accolé à traitement est une arnaque, un mensonge.

    Toutes les infrastructures actuellement en palce permettent uniquement de fiare transiter les excréments du lieu de la défécation à l'air libre jsuq'au lieu de leur dispersion dans l'environnement sous une forme ou une autre.

    Ce qui revient à dire que la gestion des excréments aujourd'hui fait que la population mondiale est toiujours dans la même configuration de la défécation à l'air libre.

    Défécation à l'air libre que des milliards de dolard sous couvert d'investissement ne font que reproduire sans apporter une rédelle solution

    Hello there is no innovative technique in the treatment of sludge as in - biology - mud is a dead organic matter.

    All organic matter - alive-the movement of life increasingly sees mother NATURE launch the process of its automatic elimination.

    But the mud of excrement out totally of any natural process. It is an organic material of a specific type that was taken out of its context of natural elimination. In addition it is an organic matter that is passed to the State of living in mud and putrid mud.

    We can search by all the means we have to try to eliminate it, it is impossible.

    The mud of excrement is a poison for the environment and disperse them in the environment is a crime against humanity.

    Indeed this mud of excrement is imbued with multiple chemical components.

    Cremated it generates a REFIUM and pollutes the atmosphere that we breathe Epandue agricultural land it contaminate our food base

    Spilled in our natural hydraulic environments it contaminates all the wildlife and aquatic flora the best attitude for this kind of problem is not to produce residue of mud.

    Off we are very far from solving this problem because all the wastewater effluent management facilities are there to produce more than 45 million tonnes of mud of excrement.

    I say management because actually the deception of the purification Word attached to treatment is a scam, a lie.

    All the infrastructure currently in place only to smuggle feces rather than open defecation in the open air to the place of their dispersion into the environment in one form or another.

    Which is to say that the management of feces today that the world's population is still in the same configuration of open defecation in the open air.

    Defecation in the open air that billions of dollars under the guise of investment are that reproduce without a real solution
