Product Description

Protein Skimmer for fine partical Removal

Protein skimmer (foam Fractionator) is a valuable device for improving water quality by removing fine organic matters and dissolved organics efficiently.

eWater Protein skimmer is specially for professional aquaculture,fish farms and large public aquariums. Equipped with Mazzei Venturi injector,eWater protein skimmer offers up to 60% increase inair intake over the turbulence,and ncrease the reaction cycle-time im the contact chamber.

Recirculating Aquaculture System

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.

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

Biofiltration

All RAS relies on biofiltration to convert ammonia (NH4+ and NH3) excreted by the fish into nitrate.

Nitrifying bacteria are chemoautotrophs that convert ammonia into nitrite then nitrate. A biofilter provides a substrate for the bacterial community, which results in thick biofilm growing within the filter.Water is pumped through the filter, and ammonia is utilized by the bacteria for energy. Nitrate is less toxic than ammonia (>100 mg/L), and can be removed by a denitrifying biofilter or by water replacement.

Solids Filtration

In addition to treating the liquid waste excreted by fish the solid waste must also be treated, this is done by concentrating and flushing the solids out of the system. Removing solids reduces bacteria growth, oxygen demand, and the proliferation of disease.

Typical RAS solids removal involves a sand filter or particle filter. Another common method is the use of a mechanical drum filter In order to remove extremely fine particles or colloidal solids a protein fractionator may be used with or without the addition of ozone (O3).

PH Control

In all RAS pH must be carefully monitored and controlled. The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system. Keeping the pH in a suitable range is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO3) or sodium hydroxide (NaOH). pH can also be controlled by degassing CO2 in a packed column or with an aerator, this is necessary in intensive systems especially where oxygenation instead of aeration is used in tanks to maintain O2 levels.

Temperature Control

All fish species have a preferred temperature above and below which that fish will experience negative health effects and eventually death. Temperature also plays an important role in dissolved oxygen (DO) concentrations, with higher water temperatures having lower values for DO saturation. Temperature is controlled through the use of submerged heaters, heat pumps, chillers, and heat exchangers.[13] All four may be used to keep a system operating at the optimal temperature for maximizing fish production.

Biosecurity

Disease outbreaks occur more readily when dealing with the high fish stocking densities typically employed in intensive RAS. Outbreaks ca n be reduced by operating multiple independent systems with the same building and isolating water to water contact between systems by cleaning equipment and personnel that move between systems. Also the use of a Ultra Violet (UV) or ozone water treatment system reduces the number of free floating virus and bacteria in the system water. These treatment systems reduce the disease loading that occurs on stressed fish and thus reduce the chance of an outbreak.
