摘要:
A sedimentation or other dewatering process conducted on a suspension is controlled by filling a body (1) that is open at its top end (2) with the suspension, establishing quiescent conditions and allowing the suspension to settle to form a supernatant layer at the top end (2), generating light from an assembly (14) and measuring the amount of scattered light (19) from the supernatant layer by a collector (21) and utilizing the measured amount of scattered light to control the dewatering.

An automatic feedback control system for a water treatment apparatus, such as a recirculating solids contact clarifier, that maintains steady-state operation of the clarifier by accurately measuring the concentration of solids at designated portions of the clarifier and automatically adjusting clarifier variables to maintain optimum conditions despite changes in the inlet flow rate, composition or temperature.

Optimale Spaltmittelmengen zur Spaltung von niedrigsalinären und hochtensidhaltigen Öl-in-Wasser-Emulsionen werden ermittelt, in dem man das Strömungspotential in der zu spaltenden Emulsion mißt.
摘要:
la présente invention concerne un procédé de traitement d'effluents consistant en la séparation des éléments en suspension contenus dans la phase aqueuse desdits effluents. Il consiste:
a) à mettre en contact lesdits effluents soit avec un matériau diélectrique pouvant se charger négativement électrostatiquement si l'on désire séparer des éléments en suspension de charge positive soit un matériau diélectrique pouvant se charger positivement électrostatiquement si l'on désire séparer des éléments en suspension de charge négative, afin d'effectuer une neutralisation des charges des éléments en suspension dans la phase aqueuse desdits effluents, b) à effectuer un processus de précipitation des effluents dont les éléments en suspension ont leur charge neutralisée, puis c) à séparer, après précipitation, la phase aqueuse des boues constituées par les éléments qui ont précipité.
L'invention concerne également une installation pour la mise en oeuvre de ce procédé.
摘要:
An arrangement for the separation by flocculation of flocculable substances contained in a suspension used particularly for purifying effluents from deinking installations where are processed used or waste paper, comprises a container (4) supplied by a conduit (2) with a suspension coming from a tank (1) and mixed with flocculating agents and with air. The container (4) contains a vertical shaft rotor (34) from which two arms (35, 36) extend outwardly at different heights. The suspension to be purified is introduced above the shaft (34) and the upper arm (36), and purified water is drawn above the lower arm (35) which forms with the upper arm an acute angle so that it precedes the latter during the rotation thereof. The supernatent substances are optionally removed from the surface by a transportation device (40) in the form of supernatent muds (8) and evacuated through a mud conduit (42).
