Abstract

Algae which settle out of a suspension are kept free of the lighter more easily suspended variety by creating waves in the culture pond. The water is added via a pan which then tilts and drops the water into the pond. The falling water creates waves which wash over a weir at the other side of the pond. The wave motion carries out suspended algae and serves to agitate the pond. The settling type algae collect on the base and are retained within the pond. System is for use on algae cultures which can subsequently be used as raw materials for methane and/or methanol production. It provides a simple, effective process which has low energy usage to keep algae cultures in settling ponds pure and free of lighter strains.

Description

"Verfahren zum Reinhalten von sedimentations- "Process for keeping sedimentation-

fähigen Algen" Der Erfindung liegt die Aufgabe zugrunde, ein einfaches, wirksames, wenig energieaufwendiges Verfahren zum Reinhalten von sedimentationsfähigen Algen, die sich in einem wassergefüllten Becken befinden, zu schaffen. capable algae "The invention is based on the object of a simple, Effective, low-energy process for keeping sediment-capable substances clean To create algae that are in a water-filled pool.

Derartige Algen können als Ausgangsprodukte für die Brzeugung von Methan bzw. Methanol dienen.Such algae can be used as starting products for the production of Methane or methanol are used.

Diese Aufgabe wird erfindungsgemäß gelöst wie im Kennzeichen des Anspruches 1 angegeben.This object is achieved according to the invention as in the characterizing part of the claim 1 specified.

In der einzigen Figur der Zeichnung ist ein Ausführungsbeispiel veranschaulicht.In the single figure of the drawing, an embodiment is illustrated.

Darin ist mit 1 ein Wasserbecken, in dem Algen gezüchtet werden, mit 2 ein Kippbehälter, mit 3 eine Wasserzulaufleitung und mit 4 ein Wasserablaufkanal bezeichnet.With 1 there is a water basin in which algae are grown 2 a tilting container, with 3 a water inlet pipe and with 4 a water drainage channel designated.

Aus der Leitung 3 strömt ständig Wasser in den Behälter 2.Water flows continuously from line 3 into container 2.

Ist dieser gefüllt, kippt er im Uhrzeigersinn, das Wasser fließt in das Becken 1 und erzeugt in diesem Wellen. Der Behälter 2 richtet sich wieder auf. Die Wellen laufen über den Rand 5 und nehmen die nicht bzw. schwer sedimentationsfähigen Algen mit. Rücklaufende Wellen führen zu einer weiteren Durchmischung.When this is full, it tilts clockwise and the water flows in the basin 1 and generates waves in this. The container 2 straightens up again. The waves run over the edge 5 and take those which are difficult or impossible to sediment Seaweed with. Returning waves lead to further mixing.

Der vordere Teil 6 des Beckens ist geneigt, um ein Auswaschen der Algen zu vermeiden.The front part 6 of the basin is inclined to wash out the Avoid seaweed.

Durch Variation der Betriebsparameter können die Wechstums und Sedimentationseingenschaften der Algen beeinflußt werden.By varying the operating parameters, the growth and sedimentation properties the algae are affected.

Im allgemeinen wird die Verweildauer der gewünschten (d.h.In general, the residence time will be the desired (i.e.

sedimentationsfähigen) Algen drei- bis zehnmal so grof) sein wie die des Wassers. Durch Querrippen kann man die Verweildauer der Algen beeinflussen.sedimentable) algae are three to ten times as large) as the algae of the water. The length of time the algae stay can be influenced by transverse ribs.
