USS007  |  Novel Partition Electrolysis Technology (PET) for Metal Recovery and Wastewater Treatment Applications

The technology provider has developed a novel electrolysis technology targeting metal recovery and wastewater treatment applications. After 5 years of intensive research and development with multiple pilot trials, the patent pending technology has demonstrated its performance in two main applications, recovery of metals from spent catalyst and ewaste, and toxic organic compounds destruction in wastewater.   The technology developed is based on a unique membrane separation design of electrochemical cells, and careful selection of solvents and optimisation of operating parameters, which allows the process solvents to be continuously recycled and metals to be recovered in a high purity metallic form.

USS014  |  Floating Controlled-release Systems for Extended Treatment of Surface of Water Bodies

This technology is a porous, water-soluble and biodegradable polymeric matrix, capable of encapsulating practically any actives. It stays afloat on the surface of water bodies for extended time periods, while releasing actives at predetermined dosages throughout the treatment period, bringing about the desired effect. This technology is currently applied to the control and eradication of mosquito larvae as well as surface algae. Potentially, it can be applied to other applications including bioremediation. Implementing this technology significantly lowers treatment cost, reduces the negative environmental impact of the actives, and improves treatment effectiveness.

USS017  |  Advanced Biofilm-based Biological Nutrient Removal Technology

The proposed technology relates to a biofilm nitrification - contact denitrification system and method in which environmental technology and water recovery technologies are used to provide advanced removal of organic carbon, nitrogen and phosphorous from waste waters. Rise in global demand for clean water, global water scarcity owing to continuously increasing population, rising water pollution, and economic development have added to the demand for advanced, energy efficient and cost efficient wastewater treatment technologies.

USS037  |  Chemical-Free Advanced Oxidation System for Degradation of High Strength Organic Waste

Aromatic organic compounds are the main pollutants in industrial effluent. Advanced oxidation processes (AOPs) have been thought as effective routes for treatment of wastewater containing aromatic compounds such as phenols. Classic AOP (Fenton reaction) requires highly acidic environment for optimal performance and generate large amount of iron oxide sludge, which needs further separation from the treated water. The proposed AOP technology doesn't require a strong acidic condition to operate, no addition of chemicals and minimal generation of sludge.

USS019  |  Low Cost and Environmental Friendly Method of Heavy Metal Removal in Water Bodies through Phytoremediation

Phytoremediation is a technology that uses plants to remove pollutants from the environment. It is an economic, energy-efficient, and environmentally friendly method which can be applied to large areas and is useful for treating a wide variety of contaminants and in numerous mediums. Remediation of contaminated sites by existing practices, such as ‘pump-and-treat’ and ‘dig-and-dump’ techniques, is often expensive and is usually only applicable to small areas. This new efficient and commercially feasible remediation technology solves the problem.

USS057  |  HABtech: Cost Effective Device for the Control of Harmful Algal Blooms

Harmful Algal Blooms are marine and freshwater blooms of phytoplankton that may cause economic, health and environmental harm. HABTech was created to respond to the urgent need to address the increasing incidence of HABs and its worsening negative effects on coastal communities. The technology is a cheaper and effective device for the control of HABs that uses a clay dispersal unit in removing blooms for the purpose of suppressing the proliferation of toxic algae, preventing paralytic shellfish poisonings and improving water quality. It uses a slurry of clay material mixed with seawater, which is sprayed onto the affected area.
