Product Introduction

The role of the recirculating aquaculture system (RAS) is to maintain thewater quality of the aquaculture water body, so that indoor (factory) aqua-culture can be realized. The system is composed of several different equip-ments. According to the different objects to be treated, the treatment stepsare as follows: After the water leaves the fsh pond, it frst passes through amechanical flter to treat the large particles (greater than 80um) of solidwaste, such as fsh scale debris and residual bait; then enter the proteinskimmer to process some semi-soluble organic matter (greater than 30 andless than 80um), such as some colloids and fne particles; and then carry outnitrifcation and denitrifcation reactions through biological flters to solve theOrganic compounds such as ammonia nitrogen and nitrite (nitrite is a car-cinogen and poses a great threat to fsh).

In addition to the above 3-stage fltration, according to the habits of thecultured species, the system can also add oxygenation equipment and tem-perature control equipment. In general, the signifcance of using the RASsystem is to provide a high-quality and controllable living environment forthe breeding industry, optimize production details and increase production.

CATAQUA integrated recirculating rs system is very suitable for temporaryapplication scenarios such as parental temporary breeding, fry hatching, in-spection and quarantine, small tank life support system, etc. The integrateddesign can save on-site installation costs and related risks. lt has low re-quirements for the on-site use environment, and the modular design canflexibly select integrated modules according to the use requirements. In ad-dition, the standard interface and tray design are very easy to connect anddisassemble,and have strong mobility.
