Municipal Wastewater Treatment

Municipal Wastewater Treatment facilities handles large continuous flows of water and treat it through a number of processes to allow it to return to nature with as small an impact as possible. This is done by using several steps of treatment, which in the end produces clean water a sewage sludge, which needs to be disposed of.

Hydrothermal liquefaction (HTL) is well suited for wastewater treatment, as it can be inserted into the process in different ways. It handles the solids or sludge present in wastewater treatment and converts it into a renewable fuel source, bio-crude, which contains less oxygen and water compared to similar technologies. The bio-crude can be upgraded at refineries into traditional drop-in fuels, such as gasoline, diesel, kerosene and heavy fuel oil. From our solution, you would also be able to create a number of value added products, e.g. bio-char and biogas.

Implementations in wastewater treatment

The easiest and most optimal way to implement hydrothermal liquefaction into wastewater treatment together with a biomass filter would look similar to this diagram:

Optimal implementation of hydrothermal liquefaction in municipal wastewater treatment

From this implementation, you will get a number of benefits, such as:

  • It presents a more efficient way of removing sludge and solids in the treatment process by converting it into bio-crude, thereby eliminating the need for transportation and disposal of heavy wet waste materials.
  • It can also effectively convert drug residuals and microplastics within the sludge into bio-crude.
  • It can possibly reduce the need for polymer additives and aeration in the wastewater treatment process.

Hydrothermal liquefaction can also be used to solely solve the problem dealing with the solids and sludge left after treatment, which wastewater treatment facilities are facing. This sort of implementation will use hydrothermal liquefaction at the end of treatment process to eliminate the need for disposal and transportation of heavy wet waste materials. It will be less effective implementation of hydrothermal liquefaction, as the sludge and solids at this stage of the process contain high amounts of ashes.

Such an implementation would look similar to this diagram:

Other applications

  • To create bio-crude from the organic fraction of municipal solid waste (including plastics) and sidestreams from agriculture and forestry.
  • To create value added products from well-known feedstocks such as lignin from second generation biomass and pulp, energy crops, straw and other organic sidestreams.
