Brand: eWater

The eWater Integrated RAS (Recirculating Aquaculture System) Aerators Equipment could be a degree that is level that is advanced that is cutting-edge to correct the difficulties of seafood farming. The item is actually a dependable and system this is certainly efficient provides oxygen that is adequate fish in an environment this is actually enclosed.
The eWater incorporated RAS Aerators Equipment comes with a component that are few works seamlessly together which means that your development this is certainly health this is certainly optimal of. The atmosphere is roofed by these components' generator, air compressor, air sensors, and diffusers.
The atmosphere generator looks after producing air. It works on the sieve this is split that is most certainly molecular and oxygen through the surroundings. The atmosphere compressor then compresses the oxygen generated by the fresh air this is certainly fresh and delivers it through the merchandise.
The atmosphere sensors sit through the machine this is certainly whole is monitor that is functional keep consistently the dissolved oxygen degree to the water. This is certainly crucial because seafood require certain oxygen amounts to survive. In the event oxygen amounts are way too low, the fish will probably be stressed that can even perish.
The diffusers, which are generally attached utilizing the bottom connected with tank for the fish, release the air that is fresh is certainly compressed the water. This creates a bubble this is certainly provides that are okay into the fish. The bubbles generated by the diffusers are evenly distributed when it comes to tank, making sure every area that is specific is right of tank is oxygenated.
The eWater built-in RAS Aerators gear has advantages that are several seafood this is certainly systems that are old-fashioned. First, the need is paid for water changes, making down it more affordable and eco-friendlier by it. 2nd, it might create sure that fish have the known amount of oxygen they need to develop and thrive. Third, this is an approach that is operational can be efficiently managed and monitored, that makes it better and customizable.
The eWater incorporated RAS Aerators gear is an item this could be certainly dependable to enhance the effectiveness and productivity of seafood farming. Its components are produced from top-quality materials which will be durable and long-lasting. The device can be very easy also to set up and run and includes an interface this is certainly user-friendly helps it really is wanted to everybody else.

RAS Description

Main eWater RAS processes and the equipment necessary

RAS are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. RAS have high fish stocking densities and can be operated economically commercial.All our eWater researchers are currently conducting studies in RAS and we have many successful indoor fish farming projects all over the world.

Main eWater RAS processes and the equipment necessary

A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps are often done in order or sometimes in tandem. After leaving the vessel holding fish the water is first treated for solids before entering a biofilter to convert ammonia, next degassing and oxygenation occur, often followed by heating/cooling and sterilization. Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximizes fish growth and health. 

Process	Equipment necessary
Biolfiltration	denitrifying biofilter,MBBR process
Solids removal	drum filter, sand filter, protein skimmer
Reoxgenating	oxygen cone or low pressure oxygenating device
PH control	degassing device
Temperature control	submerged heaters, heat pumps, chillers, and heat exchangers
Biosecurity	UV sterilizer ,ozone generator

Integrated mini RAS system

The integrated ras equipment is a complete system designed for simple setup, easy maintenance and reasonable cost. The design is flexible for a wide range of applications including saltwater or freshwater holding, rearing, aquaponics and more.
We can make a reservation according to the customer's request.
a land-based integrated RAS equipment consists of purification units:
1.  Solids collection system (a rotary drum filter)
2.  A foam fractionation unit (a protein skimmer or dissolved air floatation device)
3.  Bio-filter
4.  Sterilization system (UV sterilization or ozone generator)
5.  Oxygen injection system
6.  Temperature control (heat pump or evaporative cooling)
7.  Pump
 
The protein skimmer, UV sterilization and bio filter are the core devices. The all-in-one RAS equipment has a perfect performance structure, small footprint, and it is energy efficient, economical, safe, durable and easy to maintain. This small RAS system is designed specifically for small systems such as a processing capacity of 5 m3/h, 10 m3/h, and 15 m3/h,which require flexible movement and convenient connection.
