What Is It

What is a
RAS Solution?

A Recirculating Aquaculture System (RAS) is a closed-loop production method that filters and reuses culture water instead of constantly drawing in fresh supply. By combining mechanical filtration, biological treatment, and oxygenation, a well-designed RAS keeps ammonia, solids, and pathogens under control while cutting water consumption dramatically.

LiTENDA's RAS packages bring together MBBR bio media, drum filtration, roots blowers, and aeration equipment into one coordinated system — built to hold stable water quality even at high stocking densities.

Every project starts with free technical consultation and a tailored system design based on your species, tank volume, and biomass targets — our engineers size the right equipment before you order anything.

Engineered for Performance

Built for Continuous,
High-Density Production

Every LiTENDA RAS component is selected and configured to work as one system, not a collection of separate parts. Biofiltration capacity, mechanical screening, and oxygen supply are balanced against each other so the system holds steady even as biomass and feed rates climb.

That balance is what lets operators run higher stocking densities with lower risk — water parameters stay inside safe ranges instead of swinging with every feeding cycle.

Our team reviews your species, target biomass, and site conditions before recommending equipment sizes, so the system you install matches the production you actually plan to run — not a generic template.

Why Choose LiTENDA

RAS Solution Advantages

Every RAS package we design is built around real production conditions — not lab-scale assumptions. Here's what sets our systems apart.

Free Cost Estimates & System Design
LiTENDA provides free RAS evaluations with no obligation, sizing every component to your species, biomass, and tank geometry before you commit.
High Quality — ISO Certified Production
Bio media, filters, and blowers are manufactured under strict ISO quality controls, with a wide range of models available for flexible system configuration.
Quality & Innovation — Continuous R&D
From media surface area to filtration mesh and blower efficiency — every component undergoes rigorous testing as we continuously refine materials and designs.
Installation Support & Commissioning
Our engineering team guides every installation and commissioning phase, ensuring each RAS project is operational and producing stable water quality from day one.
System Components

What LiTENDA Equipment Does
Inside Your RAS

Each piece of equipment plays a specific role in keeping the closed-loop water cycle clean, oxygenated, and stable.

MBBR Bio Media
Component 01
MBBR Bio Media
Offers a large protected surface area for beneficial bacteria to colonize, driving the biological breakdown of ammonia and organic waste — the core of stable water quality.
Macro Drum Filter
Component 02
Macro Drum Filter
Mechanically screens out solid waste and uneaten feed before it breaks down — keeping water clear and protecting downstream biofilter performance.
Roots Blower
Component 03
Roots Blower
Supplies the air for aeration and oxygenation, keeping dissolved oxygen levels high enough for both stock and the aerobic bacteria doing the biofiltration work.
System Flow

RAS System Process

Culture water moves through mechanical filtration, biological treatment, and oxygenation in a continuous closed loop before returning clean to the tank.

Why Recirculate

Benefits of a Closed-Loop RAS

Compared with flow-through or pond-based systems, RAS gives operators far tighter control over water quality, biosecurity, and production output.

Up to 95%+ water reuse — dramatically lower freshwater intake and discharge volumes compared to flow-through systems.
Stable water parameters — continuous biofiltration and aeration keep ammonia, nitrite, and dissolved oxygen within tight ranges.
Higher stocking density — controlled water quality supports denser production per tank without sacrificing fish health.
Improved biosecurity — a closed system limits pathogen entry from external water sources, protecting your stock.
Site flexibility — RAS can run far from coastlines or rivers, opening up locations closer to processing and markets.
Lower long-term operating cost — reduced water, heating, and effluent treatment expenses over the life of the farm.
