Wie hoch ist das Bindevermögen für Phosphat bei JBL PhosEx Pond Filter ?

500 g des Granulates binden effektiv 25.000 mg Phosphat. Was sagt dieses aus über die Reichweite ?

Nehmen wir als Beispiel einen 25.000 l beinhaltenden Teich mit einer Wasseroberfläche von 28 m², der aktuell keinerlei Phosphatbealstung aufweist. Aus der News vom 16.05.2013 Springtime is algae time wissen wir, dass der jährliche Eintrag von Phosphaten etwa 8.230 mg je m² beträgt.

Multipliziert man nun die Fläche des Teiches mit dem jährlichen Eintrag, ergibt sich ein gesamter Phosphateintrag von 230.440 mg. Um diese abzubinden, benötigt man umgerechnet etwas über 9 kg JBL PhosEX Pond Filter pro Jahr.

Pro Tag sind das bei unserem Musterteich immer noch 631 mg. Daraus ergibt sich eine rechnerische Reichweite von 500 g JBL PhosEX Pond Filter von 39 Tagen.

Bei dieser Musterrechnung ist zu berücksichtigen, dass nicht alle natürlich in den Teich eingetragenen Phosphate wirklich auch von Algen aufgenommen werden und in den biologischen Kreislauf gelangen. Die realistische Reichweite von JBL PhosEX Pond Filter beträgt für unseren modellhaften Gartenteich etwa 2 Monate.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
