Product Overview


Product Description

RAS Recirculating Aquaculture System
It is a new type of aquaculture mode, through a series of water treatment units, the wastewater generated in the aquaculture pond
is treated and recycled again. The main principle of RAS is to integrate advanced technologies in environmental engineering, civil
construction, modern biology, electronic information and other disciplines to remove residual bait manure, ammonia nitrogen (TAN),
nitrite nitrogen (NO2--N) in aquaculture water. ) and other harmful pollutants for the purpose of purifying the breeding
environment, using physical filtration, biological filtration, removal of CO2, disinfection, oxygenation, temperature adjustment
and other treatments to re-enter the purified water body into the breeding pond.

Recommended scheme for aquaculture system
According to the actual site, scale and aquaculture needs of customers, we customize the factory aquaculture system scheme with high stability as required, apply modern scientific and technological means, and achieve the goal of high yield and high income for customers under the condition of saving land, energy consumption and water resources.

Composite degassing processor
The compound degassing tower sterilization processor is composed of water inlet device, degassing tower main assembly, packing and
aeration device. It can effectively remove harmful gases such as oxygen dioxide, improve dissolved oxygen in water, and quickly
and effectively kill various bacteria, viruses and other microorganisms; Through photolysis, chloride in water is degraded.

PP fish pond
Dayu fishery technology is a special fish pond specially designed for the industrial circulating water culture treatment system, hatching and seedling raising, parent fish, parent shrimp and adult fish culture. It is environment-friendly, non-toxic, long service life, smooth surface, corrosion-resistant, anti-aging, anti-seepage and high strength. This fish pond is easy to use, and the inlet and outlet are connected with a single operating cylinder

① The site selection is flexible and independent of large clean water sources.
② Reduce wastewater discharge.
③ Improve biosafetyand ease treatment of disease outbreaks.
④ Be able to closely monitor and control environmental conditions to maximize
productivity. Similarly, it is independent of weather and changeable environmental conditions.

More room for culture Improve the rate of bacteria hanging and film forming speed.
Intercept macromolecular organics, reduce the load on the biochemical bin. The structural design of multi-dimensional filaments
provides a place for nitrobacteria to attach and reproduce, helping to quickly establish the nitrification system
Fine filtration to intercept fine impurities
Intercept macromolecular organics, reduce the load on the biochemical bin, create a good hotbed for the propagation of nitrifying
bacteria, improve the overall filtration efficiency, and create ecological water purification
Better bacteria culture effect
It can cultivate nitrifying bacteria, accelerate the formation of nitrification system, and thus decompose small substances and
harmful substances such as ammonia and nitrite nitrogen

Application Scenarios

Widely used
It is mainly used in aquaculture filtration and fish pond culture
