Hygienic Design Filter for GMP and High-Purity Processes
STERIBAC is a fully enclosed, self-cleaning filter system designed for sterile and hygienic solid-liquid separation. It supports CIP and SIP procedures and GMP-compliant processes.
Sterile Filtration for Sensitive and Regulated Processes
STERIBAC is designed for applications where product purity, process safety, and regulatory compliance are essential. Built for full containment and easy cleanability, it delivers efficient solid-liquid separation with minimal operator exposure. Its hygienic design and smooth internal surfaces make it ideal for pharmaceutical, biotech, and food-grade environments.
Hygienic, Closed-System Design
STERIBAC is built for sterile and high-purity processes. The fully enclosed design minimizes contamination risk and allows for safe, contained operation.
CIP/SIP Compatibility
All product-contact surfaces are designed for complete cleanability. The system supports automated Cleaning in Place and Sterilization in Place procedures, reducing downtime and ensuring compliance.
Minimal Product Loss
Efficient cake formation and controlled discharge allow for high product recovery. The system reduces waste and improves yield in sensitive or high-value applications.
Hygienic Internal Layout
The STERIBAC vessel is engineered with hygienic design principles, featuring sloped surfaces, tangential connections, and strategically placed spray nozzles. All product-contact surfaces are polished or electro-polished to support complete drainability, effective CIP/SIP coverage, and compliance with GMP standards.
During operation, the process slurry flows into the vessel, and solids are retained on the outer surface of the filter media. The clarified filtrate passes through the cloth into the candle core and exits the system. This setup ensures consistent cake buildup, enabling stable performance and high filtrate clarity with each cycle.
Once filtration is complete, compressed gas is injected through the candle core to initiate a back-flush. This dislodges the filter cake, which is then discharged from the vessel in a controlled manner. The self-cleaning cycle regenerates the filter media for the next batch, minimizing downtime and operator intervention.

Heel volume filtration is a patented process that allows our filters to recover the residual liquid (the “heel”) that remains at the bottom of the vessel after standard filtration is complete. Instead of discarding this heel or leaving valuable product behind, the system recycles it using a smart flow design.
How it works:
From the lowest point in the vessel, the heel is pumped back via the feed pump and dispersed through a centrally located spray nozzle in the filter cover.
This creates a fine spray that is evenly distributed over the filter elements.
The heel liquid is then pushed through the existing cake using gas pressure, completing a final filtration step and increasing yield.
This method also supports efficient cake washing, where the wash liquid is sprayed in the same way. Because the liquid is evenly dispersed and pushed through the cake with minimal volume, this technique significantly reduces wash liquid consumption compared to conventional methods.
Why it matters:
Increases yield (less product loss)
Facilitates batch integrity
Reduces waste volume and environmental load
Improves cost-efficiency
