Digester Covers – Digester Cover Design for Biogas Plants

Every digester deepends upon its cover to provide a good air-seal, but are you aware of the digester cover types and the other purposes of these covers?

We talk about digester cover design, the popularity of membrane digester covers, like walker process digester covers. In fact we think you will find digester gas storage, whether as a floating roof digester cover, double membrane gas holder interesting. See also suppliers westech engineering, and ovivo.

Digester Covers. Those Distinctive-Looking Curved, Biogas Tank-Tops

Anaerobic-digestion plant biogas-digesters, are normally covered with a fixed, or floating top, for gas collection.

These tank tops are a very distinctive shape. Once you recognize that shape, an anaerobic-digestion plant is easy to spot from a distance.

There are 3 types:

First. Floating covers which rise-and-fall according to volume of gas and substrate and their weight provides the gas pressure.

2. Fixed covers which require a separate biogas-holder connected to the space above the digester, that allows the gas to move in both directions.

3. The most popular and easily-recognised distinctive double flexible-membrane covers.

In all but the first type of digester-cover, the pressure of the gas is controlled by an automatic pump.

Digester covers are designed to provide the following:

a) A permanent seal to prevent oxygen entering the digester.

b) A degree of pressurisation to the biogas.

c) In cold countries the cover must provide heat-insulation to keep the digester warm.

Double membrane digester covers are popular, due to their low cost, and when manufactured to high-quality standards they have a remarkably-long service-life.
