Basin separation aquaculture net Bio Seize

Product overview
ELDI Bio Seize is a sludge and biowaste collection system for aquaculture that extracts faeces and surplus feed before sludge formation. The system uses gentle particle extraction to collect solids with minimal water use and low energy consumption, enabling up to 80% dry matter recovery and improving handling and transport of collected material.

ConeCollect (component)
The ConeCollect is the next-generation Collect net supplied with Bio Seize. It is a separate, customizable cone-shaped net attached to the main cage net to segregate fish from biowaste and concentrate particles for easier processing. ConeCollect is compatible with standard farming nets and designed for simple installation and retrofit.

Key process and results

• Minimal water use and low energy consumption for bio-waste collection
• Up to 80% dry matter recovery from collected material
• Gentle extraction of faeces and surplus feed to prevent sludge formation
• Separation of faeces from feed, enabling potential feed reuse
• Dry bio-waste energy content: 3,700 kWh per 1,000 kg (stated), yielding a net energy gain

Benefits / Performance topics presented on the page

• Dry matter recovered from feed and faeces
• Energy required to capture 1,000 kg dry matter
• Energy required to sanitize and dry 1,000 kg bio-waste to 85% dry matter
• Net energy gain/loss based on 3,700 kWh per 1,000 kg dry bio-waste
• Separation of faeces from feed (potential reuse)

Testing and deployment
On-site testing in June 2025 demonstrated reduced handling complexity and improved efficiency in sludge collection, transport and processing operations.
