Lodomat
Lodomat consists of a suite of technologies that involve the use of free nitrous acid (FNA) for the treatment of wastewater sludge to enhance volatile solids destruction, enhance biogas production in anaerobic sludge digestion, to improve sludge dewaterability and to improve biological nitrogen removal.
Key features
- Lodomat is an advanced system for wastewater treatment of sludge utilising anaerobic digestion, free nitrous acid, partial nitration and mainstream deammonification
- Lodomat technologies were developed at the Advanced Water Management Centre at the University of Queensland
- Lodomat AD, NP, NIT and MD have continued to improve on each technology to reduce biosolids to be disposed of and recover energy in the form of methane or biogas.
Alkaline digestion of waste glass
There is a narrow range of reaction conditions under which the alkaline digestion of soda-lime glass and separation of resultant products is able to proceed in a commercially relevant way. UQ researchers have optimised digestion conditions and product processing, such that glass can now be used to produce a range of high-value products including liquid alkali-silicates in all commercially relevant concentrations and ratios, high purity silica gel and Calcium Silicate Hydrate (CSH).
Key features
- Simple process developed for the extraction of sodium silicate from soda-lime glass, characterised by a high utilisation of the raw materials and energy embodied in glass
- Suitable for the low-value fraction of waste glass which is too small to be optically sorted (by colour) and remade into glass products
- Significant commercial (reduced capex and opex) and social benefits (reduce landfill and consumption of virgin materials) when compared to conventional production routes of sodium silicate.
