Biothane Biobulk™

Treats industrial effluents with a wide range of concentrations, at maximum removal efficiency
The Biothane Biobulk™ technology is a robust and proven process, with a high tolerance for solids, fat and high organic concentrations. This makes the solution most suitable for dairy, meat processing and potato process type of effluents.

Biobulk™ CSTR

Blended solid or liquid waste streams enter the reactor and are treated by anaerobic suspended bacteria. The majority of the soluble or solid COD (Chemical Oxygen Demand) is converted into biogas, significantly reducing the solids concentration in the waste stream. After a retention time of several days, the treated waste stream leaves the reactor. The Biobulk™ CSTR can be operated as a once-through system. Alternatively, biomass can be returned after a clarification stage. The key to the Biobulk™ CSTR design is the manner in which the reactor vessel is mixed and the design of the degassing stage prior to clarification.

Produced biogas is temporarily collected in the headspace of the Biobulk™ CSTR reactor which acts as a biogas holder. Biogas can be used as a source of renewable energy or burned in a biogas flare.
 

Features and benefits

  • Medium volumetric loading capacity (2-5 kg COD/m3/day)
  • Maximum Biogas production
  • Proven reliability

Applications 

  • Industrial Wastewater Treatment
  • Sludge Treatment

Biobulk™ SPAR

Biobulk™ SPAR is  designed to treat industrial effluents with a wide range of concentrations, at maximum removal efficiency. The system is designed for having a high tolerance to concentrated Fat, Oil and Grease and or high levels of suspended solids. This benefits in having no requirement for a primary treatment.

Without the need of any pretreatment (other than screening), the acidified content of the buffer tank is fed to the Biobulk™ SPAR reactor in batches. Once in the reactor, the substrate is efficiently converted into valuable biogas by the suspended anaerobic biomass. Thanks to Biobulk™ SPAR unique sequence, the substrate is completely degraded, enabling maximum biogas production. Finally, the advanced process of biomass degassing takes place in the Batch Degassing Tank . The final effluent is clarified in the Semi-Continuous Settler . Whilst the separated effluent is discharged, concentrated biomass is simultaneously returned into the anaerobic reactor to start the Biobulk™ SPAR sequence again.

Features and benefits

  • High tolerance to fats and/or suspended solids in feed
  • Self regulated & SMART control
  • High tolerance to feed fluctuations
  • No pretreatment
  • High operational flexibility
  • Maximum Biogas production

Applications 

  • Industrial Wastewater Treatment
  • Sludge Treatment
