Overview

Indoor RAS and outdoor RAS Rotary drum filter for aquaculture for fish farm pond

Industrial aquaculture recirculating system:

1. Drum fiter: to separate solid particles (fish feces and residual bait)

2. Protein skimmer: to separate dissolved protein and fine solid particles

3. Ozone disinfection machine: (can be replaced by UV disinfection equipment), to remove bacteria and viruses in water

4. CO2 stripper: to remove carbon dioxide from water, improve pH value and increase dissolved oxygen

5. Biofilter: to remove nitrite

6. Water quality monitoring system: real-time monitoring of water quality indicators and real-time feedback control

7. Oxygen cone: pure oxygen oxygenation

8. Fish pond: round, cone bottom, easy to drain

9. Aquaculture waste dewatering: Volute screw sludge dewatering machine

10. Others: thermostatic system

Drum filter introduction

The automatic box type rotary drum filter is mainly composed of box components, drum components, back cleaning system and electric control box. The treatment capacity can be customized according to demand, and it’s made of non-toxic, corrosionresistant and environmental protection materials.SS316L filter screen is used to separate suspended solids in water. When the water containing suspended solids enters the drum, the suspended solids are intercepted by the stainless steel filter screen, and the water without suspended solids enters the reservoir after filtration. When the suspended solids in the drum accumulate to a certain amount, it will cause the water permeability of the filter screen to drop, resulting in the rise of the water level in the drum.The liquid level automatic control system works. At this time, the back cleaning water pump and the drum motor are automatically opened at the same time. The high-pressure water output from the back cleaning water pump cleans the rotary drum filter screen and the cleaned suspended solids flow to the wastewater collection tank under the high-pressure water washing and are discharged through the wastewater pipe.When the filter screen is cleaned, the water permeability of the drum filter screen rises and the water level in the drum drops. When the water level drops to the set low water level, the backwashing water pump and the drum motor will automatically stop working, and the drum filter will enter a new round of working cycle.TPA:20-150m3/HTPK: 200-500m3/H

Frequently Asked Questions

What is a RAS recirculating aquaculture system?

A RAS (Recirculating Aquaculture System) is an advanced fish farming technology that recycles water to maintain optimal conditions for fish growth while minimizing waste and water use.

What types of fish can be farmed using this system?

This system is designed primarily for tilapia, but it can also be adapted for other species of fish, depending on the specific requirements of the aquaculture operation.

How does the rotary drum filter work?

The rotary drum filter separates solid particles from water using a stainless steel filter screen. Water containing suspended solids enters the drum, where the solids are trapped, and filtered water flows to a reservoir.

What is the purpose of the protein skimmer in the system?

The protein skimmer is used to separate dissolved proteins and fine solid particles from the water, helping to maintain water quality and reduce organic waste.

How does the ozone disinfection machine work?

The ozone disinfection machine removes bacteria and viruses from the water, ensuring a clean environment for fish. It can also be replaced by UV disinfection equipment.

What is the role of the CO2 stripper?

The CO2 stripper removes carbon dioxide from the water, improving pH levels and increasing dissolved oxygen, which is essential for fish health.

How often should I monitor water quality?

It is recommended to monitor water quality indicators in real-time using the built-in water quality monitoring system to ensure optimal conditions for the fish.

What is the capacity of the drum filter?

The treatment capacity of the drum filter can be customized according to demand, with options ranging from 20-150m3 for TPA and 200-500m3 for TPK.

Is the system easy to operate?

Yes, the system is designed for ease of operation with automatic controls for backwashing and monitoring, allowing for efficient fish farming with minimal manual intervention.

What materials are used in the construction of the system?

The system is made from non-toxic, corrosion-resistant, and environmentally friendly materials, ensuring durability and safety for aquatic life.

What is the function of the biofilter in the system?

The biofilter is used to remove nitrite from the water, which is crucial for maintaining a healthy aquatic environment for the fish.

Can this system be used for both indoor and outdoor aquaculture?

Yes, the system is versatile and can be effectively used for both indoor and outdoor aquaculture operations.

What is the purpose of the oxygen cone?

The oxygen cone provides pure oxygen to the water, enhancing oxygenation which is vital for fish respiration and overall health.

How is aquaculture waste managed in the system?

Aquaculture waste is managed using a volute screw sludge dewatering machine, which efficiently separates and disposes of waste materials.

What kind of maintenance does the system require?

Regular maintenance includes cleaning the drum filter, monitoring water quality, and ensuring that all components, like the protein skimmer and ozone disinfection machine, are functioning properly.
