Solar-thermal Zero Liquid Discharge (ZLD) system

Many industries, such as Oil, Gas, and Mining, benefit from a Zero Liquid Discharge (ZLD) approach to their wastewater treatment. Raw wastewater can be acidic and highly saline, and often contains large amounts of sediment. The existing ZLD solutions are either energy-intensive and require high-grade electric energy or space-intensive and have high capital costs. Pre-treatment is required, and in some cases, environmental concerns arise.
To help reduce the high costs of wastewater disposal and lower environmental impact, SunCatch Ltd develops the novel concept of the Solar-thermal Zero Liquid Discharge (ZLD) system. Our concept of ZLD technology uses renewable solar thermal energy to evaporate liquids from the discharge and recover solids suitable for secondary use.

Our ZLD unit is designed to produce zero liquid discharge in the form of dry/crystallized solids that can be easily recycled and reused while providing effective brine management in accordance with environmental regulations. The combination of the components and innovations applied in our solution ensures low capital and operating costs, including minimal to zero conventional energy consumption.

In the proposed configuration, our ZLD system can be applied in the Oil & Gas and mining industries as well as the agricultural sector. Complete with PV panels, it can be fully autonomous and suitable for remote and rural areas where access to electricity is limited.

We aim to create a highly efficient system with minimal capital and operating costs that requires no complicated maintenance and can operate continuously.
