Modular sewage treatment plant fits inside a trailer

The solution cleans water sufficiently for reuse in gardening, flushing, and outdoor cleaning

Spotted: An incredibly densely populated country, India’s struggles to access and maintain clean waterways and sanitation infrastructure is well documented. UNESCO says that lack of sanitation is part of the global water quality challenge and “one of the most significant forms of water pollution.”

Israeli company Huliot has a solution specifically for densely populated communities. A modular sewage treatment plant called ClearBlack can clean water for up to 800 people per day per unit. The plants are available in three sizes, ranging from 25 to 100 cubic metres of water cleaned per day. Based on a compact design centred around a Membrane Bio Reactor (MBR) rather than activated charcoal or sand filters, the mobile treatment plants are quiet to run, do not produce a smell, and are automatically and remotely managed.

The system requires only electricity to run, no additional piping, and costs around 15 cents per day. With almost 100 per cent of the water that is cleaned able to be used again, the system is incredibly efficient and could cut local water costs and volume of use by up to 40 per cent.

As water scarcity continues to grow globally, solutions such as Huliot’s have the potential to significantly improve urban living conditions. Springwise has previously spotted innovations taking inspiration from nature, with apples being used to remove nanoplastics and algae providing a chemical-free cleaning process.
