Reducing liquid effluent disposal costs and environmental impacts

High rate liquid anaerobic digestion is an ideal process for treating liquid effluents and residues from biofuel production and other industrial processes.  Clearfleau’s innovative customised treatment plants generate energy from liquid effluents.

High rate digestion has applications in the biofuels sector and other industrial sectors, such as paper manufacture, light chemicals and oils.  With access to FIT and RHI payments, generation of biogas from liquid wastes could have a substantial impact on the economics and environmental footprint for a number of industrial processes.

Bio-fuel production depends upon conversion of organic feedstocks and its residual materials are suited to high-rate anaerobic digestion.  Materials with significant biogas potential include: 

  • Thin stillates from the production process
  • Wash down residues and bio-effluents
  • Gums and other high COD residues

Clearfleau’s plants treat these by-products and produce electrical power and heat that can be offset against the energy costs of the industrial processes.  Clearfleau’s treatment plants can also be integrated with existing treatment systems.

Clearfleau has operated its mobile trials unit on a UK bio-fuel site.  The successful trials achieved 98% COD removal. 

In addition to cutting costs and providing a new cost effective treatment option for other sectors, the benefits of the process include:

  • Reduced effluent discharge and haulage of waste off-site
  • Generation of electricity and surplus heat for use on-site
  • Phosphate recovery into a slow release natural fertiliser
  • Potential for recycled water to partly replace existing supply
  • Reduction in the carbon footprint of production processes

Many companies can expect to face carbon taxes on their production and waste management processes. Clearfleau offers a solution that will reduce taxes, cut costs and generate revenue.

The UK’s Integrated Pollution Prevention and Control regulations (IPPC) require companies to make continual improvements in environmental standards.  ISO 14001 on environmental management requires periodic audit of environmental systems and management. Renewable energy and water recycling investments are eligible for enhanced capital allowances (ECAs).
