Use the drum filter correctly
from ECOWATER AQUA


 
As an example, drum filters are common in RAS system equipment. The feces of fish and shrimp tend to be in strips and not so loose. If the manure stays in the water for too long, it will be loosened by microcurrents, making the particles smaller. At the same time, under the action of bacteria, some of it will decompose into soluble ammonia, nitrogen, nitrite, and other harmful substances. Therefore, it is very important to filter the feces out of the water in the first place. Then, the feces as a whole are transported through the artesian flow into the filter net of the drum filter, and then, through the automatic change cleaning of the drum filter, the feces , and residual bait are separated from the water. This is the right way to use the drum filter.
 
If the pump is designed in front of the drum filters, the feces of fish and shrimp will be broken up by the high-speed rotating pump impeller when they pass through the pump. We know that the filtration accuracy of the drum filter is generally above 60 microns. Particles smaller than 60 microns are difficult to filter. Then, since this part of the organic suspended matter is less than 60 microns in diameter and cannot be filtered out by the drum filter, it will decompose into ammonia, nitrogen, subsalt, and other harmful substances in the water. To filter out these particles smaller than 60 microns, we should be in a situation like the one above. Avoid the sewage of the breeding pond, first through the pump and then through the micro-filter. If these details are not designed correctly, the system can easily collapse, allowing large amounts of ammonia and nitrite to accumulate. Even with a large biochemical filtration system, these ammonia, nitrogen, and subsalts cannot be broken down from the water in time. The cost of the system increases dramatically. It can also easily lead to the failure of the entire RAS system
.

A professional RAS system must be achieved through actual operation, repeated verification, and improvement. In future articles, we will share more professional knowledge about the RAS system.
