eWater - Model 300m³/H -Aquaculture Drum Filter
The rotary drum filter can effectively remove organic compounds from outlet water coming from fish tanks as well as cleaning the inlet water entering the farm. Able to remove 42%-75% of the total particles from aquaculture water volume. New designed rotary drum filters with complete series, and cover all needs for mechanical filtration in aquaculture production;
- Good quality screens for easily rinsing and durable performance.
- Filtration precision: 30-120 um.
- Specialized design of the rinsing system for removing 98% of the filtered particles.
- Warranty 2-3 years, with more than 10 years using life.
Mechanical filtration is often the first step in the recirculation loop. The task is to remove faeces and other particles from the water before they break down in smaller particles. Smaller particles are harder to capture and result in adverse water quality conditions. Organic loading increases bacterial growth, reduces the biological filter performance and decreases water quality.
In the farm designs drum filters are usually the tool of choice for solid removal. This is basically a halve submerged rotating cylinder, covered with a fine screen. Waste water is led into the drum and passes through the screen, leaving solids trapped against the screen. The drum then rotates dirty cloth out of the water, where water jets are used to spray the captured solids into the waste water collection drain. A normal screen size has openings of 36-40 micron, which allows for capture of parasites. The drawback of drum filters is the cost of investment, the complexity, operating cost and the fact that very fine solids are not captured
