Continuous treatment, no cycle gaps
Effluent is processed as a steady stream rather than in discrete batches, eliminating accumulation of untreated waste, removing cycle wait times, and enabling uninterrupted production operations.
The patented FDS Continuous Flow system (industrial decontamination unit) was built for facilities where batch treatment can no longer keep pace with production. Treating effluent in a steady, uninterrupted stream rather than in discrete cycles, delivering guaranteed decontamination, maximum energy efficiency, and fully automatic operation for vaccine manufacturers, large-scale biotech facilities, and high-containment research campuses where downtime is simply not an option.
Custom-engineered to your specifications. Specific design available for BSL4 containment and ATEX requirements.
Batch decontamination systems are the right tool for a defined range of applications, intermittent effluent flows, variable daily volumes, and facilities where treatment can wait for a tank to fill. But as production scales up and effluent flows become continuous, sustained, and high-volume, the limitations of batch technology become operational constraints: cycle wait times slow throughput, large storage tanks consume valuable floor space, and the gap between treatment cycles creates windows where untreated effluent accumulates.
The FDS Continuous Flow system eliminates these constraints entirely. Rather than collecting and treating effluent in discrete batches, the FDS processes it as a continuous stream. The system heats the effluent to the required treatment temperature as it flows through, holds it at that temperature for the validated time, and then cools and discharges it in a single uninterrupted sequence. There is no cycle wait. There is no storage bottleneck and no accumulation of untreated hazardous waste. Just a steady, validated, and fully documented decontamination process running in real time alongside your production operations.
The FDS system’s performance is built around its all-welded tube-in-tube heat exchanger design. Every connection in the effluent circuit is fully welded, no gaskets, no mechanical seals, no joints that can fatigue or fail under the thermal and pressure cycling of continuous operation. The absence of dead zones and preferential flow paths within the exchanger ensures that every volume of effluent passing through the system receives uniform thermal treatment, with no cold spots, no bypass channels, and no risk of untreated effluent reaching the discharge point.
The tube-in-tube geometry also enables very high fluid flow velocities within the exchanger, creating turbulent flow conditions, eddy diffusion, that dramatically improve heat transfer efficiency compared to conventional shell-and-tube designs. The practical result is faster, more uniform temperature distribution across the entire effluent stream, shorter holding sections, and a more compact overall system footprint for any given treatment capacity.
Materials throughout the FDS are selected in accordance with the most stringent American pharmaceutical regulatory guidelines, with particular attention to chloride resistance, ensuring long-term performance in environments where effluent composition can be aggressive to standard stainless steel.
At the scale of continuous flow decontamination, energy consumption is a significant operational cost. The FDS addresses this directly with an integrated energy recovery section that uses the thermal energy contained in the treated effluent, which exits the decontamination section at high temperature, to pre-heat the incoming cold effluent entering the system.
This counter-current heat exchange recovers up to 80% of the thermal energy used in the decontamination process, dramatically reducing the steam or electricity required to bring each new volume of effluent to treatment temperature. The result is a continuous flow system that delivers industrial-scale throughput at a fraction of the energy cost of systems without recovery, lowering both operating expenses and environmental footprint simultaneously.
In regulated pharmaceutical and biotech environments, decontamination systems are not just operational equipment; they represent GMP-critical assets subject to formal qualification protocols. Moreover, the FDS design supports fast, straightforward qualification from the ground up. To facilitate this, standard documentation packages, including qualification protocols and procedures, accompany every system delivery. Consequently, this approach significantly reduces the time and resources you must invest to achieve operational release after installation.
Furthermore, redundant control of decontamination parameters—specifically time, temperature, and pressure for Prion-level requirements—ensures that the system meets the most stringent regulatory expectations, including BSL3, High Risk Level, and SIL 3 compliance standards. In addition, should a decontamination cycle fail, the system automatically diverts effluent back to the storage tank and initiates a sanitization cycle. Ultimately, this process requires no operator intervention, which ensures that untreated effluent never reaches the discharge point.
Effluent is processed as a steady stream rather than in discrete batches, eliminating accumulation of untreated waste, removing cycle wait times, and enabling uninterrupted production operations.
Zero gaskets, zero mechanical seals, zero dead zones. The fully welded heat exchanger circuit eliminates every common source of leakage and cross-contamination in high-throughput decontamination systems.
Any loss of treatment parameters triggers an automatic diversion of effluent to the storage tank and initiates a sanitization cycle, with no operator intervention required and no risk of discharge compliance failure.
Very low tube fouling characteristics allow extended production runs between cleaning cycles, while the compact single-skid design provides direct access to all components for rapid maintenance turnaround.
Standard qualification protocols and documentation packages are included with every system, reducing the time from installation to operational release in GMP-regulated environments.

At the industrial scale, the consequences of a decontamination failure extend far beyond a compliance citation. Indeed, they affect production continuity, public health, and your facility’s operating license. To address this, Actini provides the engineering expertise and proven track record to ensure those risks never materialize.
Furthermore, with hundreds of large-scale systems installed in vaccine manufacturing facilities, government research campuses, and biotech production sites across the US and worldwide, facilities trust Actini when getting it right is the only acceptable outcome. Ultimately, ISO 14001 certification and a “Made in the USA” manufacturing standard back our commitment.
