BioCap digester covers are designed with essential safety and operational features, including pressure relief valves, flame arrestors, site access ports, and sediment traps. We also provide proprietary LanceMix® mixing systems with gas compressors, external sludge mixing with internal nozzles, FlareWell® gas flares, and pre-treatment screening and thickening technology with the advanced Huber Strainpress, offering a complete solution for all digestion equipment needs.
Key Features of BioCap Digester Covers:
Biogas Containment: Effectively captures methane-rich biogas for energy generation, reducing greenhouse gas emissions.
Durable Materials: Constructed in New Zealand from high-quality materials to withstand harsh environmental conditions and provide long service life.
Flexible Design: Available in different configurations to suit various digester types and operational requirements.
Odour Control: Helps in controlling odours by sealing the digester, preventing the release of gases.
Low Maintenance: Designed for easy operation and minimal maintenance requirements.

LanceMix® Mixing Systems for Anaerobic Digesters
Hydroflux Epco offers LanceMix® mixing systems as a key component in its anaerobic digestion solutions. The LanceMix system uses gas compressors to circulate biogas through lances installed inside the digester, ensuring effective and uniform mixing of sludge. This enhances the contact between microorganisms and organic matter, improving the efficiency of the digestion process and optimising biogas production.
In addition to LanceMix, Hydroflux Epco provides other mixing options, such as external sludge mixing systems with internal nozzles. These systems circulate sludge externally through heat exchangers or mixing loops before reintroducing it into the digester, ensuring thorough mixing and maintaining optimal temperatures. Both LanceMix and external sludge mixing systems are designed to improve operational efficiency, enhance biogas yield, and provide reliable, low-maintenance solutions for anaerobic digestion facilities.
Digester Cover and Mixing FAQs
Explore our clarifier FAQs to learn more about Hydroflux Epco’s BioCap digester covers and ancillary equipment
Digester covers are available in two main types: floating and fixed, each designed to suit different operational requirements and process conditions.
Floating digester covers adjust to changes in gas volume, rising and falling as biogas production fluctuates. This design helps maintain a consistent internal pressure, optimising gas storage while preventing excessive buildup. Floating covers are particularly beneficial in systems where biogas generation varies significantly.
Fixed digester covers provide a rigid, stable enclosure for the digester, ensuring a controlled environment for biogas collection and process management. These covers are commonly used in installations with consistent operating conditions. Fixed covers also provide structural support for additional equipment, such as pressure relief systems, gas flares, and safety devices, making them an integral component of well-regulated anaerobic digestion systems.

A high-quality digester cover should be equipped with various features to ensure safe and efficient operation. This may include:
- Pressure relief valves: Prevent excessive pressure buildup by allowing controlled gas release when needed, ensuring system safety.
- Flame arrestors: Protect the system from potential ignition sources by stopping flames from entering or exiting the gas collection area.
- Site access ports: Allow for easy inspection, maintenance, and sampling without disrupting digester operations.
- Sediment traps: Help capture and remove solids that may settle within the system, preventing blockages and maintaining efficiency.
