Characterization of sludges - Good practice of sludge dewatering

This CEN Technical Report describes good practice for sludge dewatering and belongs to a series on sludge management options.
It gives guidance on technical and operational aspects of:
-   conditioning, thickening and dewatering processes.
Drying, which is another water content reduction process, is not dealt with in this document, but in CEN/TR 15473, Characterization of sludges - Good practice for sludges drying.
This report is applicable for sludges from:
-   urban wastewater treatment plants;
-   treatment plants for industrial wastewater similar to urban wastewater;
-   water supply treatment plants.
This document may be applicable to sludges of other origin.

Caractérisation des boues - Bonnes pratiques pour la déshydratation des boues

Le présent Rapport technique CEN décrit les bonnes pratiques pour la déshydratation des boues et fait partie d’une série concernant les filières de gestion des boues.
Il fournit des lignes directrices concernant les aspects techniques et opérationnels des procédés suivants :
-   conditionnement, épaississement et déshydratation.
Un autre procédé de réduction de la teneur en eau, le séchage, n’est pas traité dans le présent document mais dans le CEN/TR 15473, Caractérisation des boues - Bonne pratique pour le séchage des boues.
Le présent rapport est applicable aux boues provenant :
-   des stations d’épuration des eaux usées urbaines ;
-   des stations d’épuration des eaux usées industrielles similaires aux eaux usées urbaines ;
-   des stations d’épuration des eaux de distribution.
Le présent document peut s’appliquer aux boues d’origines différentes.

Karakterizacija blata - Dobra praksa za postopek odstranjevanja vode

To tehnično poročilo opisuje dobro prakso za postopek odstranjevanja vode iz blata in je del standardov, ki se nanašajo na možnosti ravnanja z blatom. Podaja navodila glede tehničnih in obratovalnih vidikov priprave, zgoščevanja in odvodnjavanja. Sušenje, ki je še en proces za zmanjšanje vsebnosti vode, ni obravnavano v tem dokumentu, temveč v CEN/TR 15473, Karakterizacija blata – Dobra praksa za sušenje blata. To poročilo velja za blato iz: čistilnih naprav za mestno odpadno vodo; čistilnih naprav za industrijsko odpadno vodo, ki je podobna mestni odpadni vodi; čistilnih naprav v sistemih oskrbe z vodo. Ta dokument se lahko uporablja za blato drugega izvora.
