6.2. Solid Waste Filter

In the geothermal system, they are the filters used for the separation of inedible feed, fish

excrement and other suspended solids accumulated in tanks from the water. It can be in
different sizes and shapes according to the purpose of use and the size of the system. Amateur

geothermal producers can create a simple and convenient solid waste separator themselves
using barrels and PVC pipes. However, commercial type manufacturers use more professional

solid waste filters since it is important for the continuity and automation of the system.

6.2.1. Drum Filter

Drum filter is a type of filter where the water from the fish tanks is collected and drained from

a cylindrical drum and separated from the solid wastes. Here, the top of the drum-shaped part
is covered with a special cloth with pores of different sizes (such as 5-200 microns), and this

drum rotates continuously and ensures that the solid wastes in the water passing through it are

attached to the cloth. The cloth, whose pores become clogged over time, is cleaned
automatically by spraying water from the buttons on the reverse, and solid wastes are thrown

out of the system through a channel.
