Reinventing water treatment

Zero wastewater discharge

Hydrokemos is a highly innovative water engineering company that offers global solutions for water purification, drinking water treatment and reuse through its modular HYK system.

High performance removal of nitrogen compounds, such as ammonium, nitrates or urea, cyanides, pharmaceutical APIs, organic matter, solvents, aromatic compounds, among others. All this without adding chemical additives, without generating sludge or rejects and with very competitive operating and investment costs.

Zero Drop Electro Treatment

eliminates oxidizable compounds and turns it into nitrogen, oxygen, carbon dioxide and hydrogen gas, without generating any type of solid or liquid waste.

100% water harvesting

Zero drop technology uses all the water and does not pre-concentrate the pollutant

No chemical reagents

Energy accounts for 98% of the operating cost and only 2% goes to reagents.

Modular and expandable

HYK technology is an easily scalable and expandable modular system. Modules are supplied according to the needs to eliminate the pollution load.

Robust and autonomous system

allows the plant to run practically autonomously. The system also features a remote control and remote management system

Competitive cost

Highly competitive in terms of capital expenditure (CAPEX) and operating expenditure (OPEX)

Electro treatment of industrial wastewaters

The HYK technology, developed by Hydrokemos, is a specific electrochemical technology for the elimination of oxidizable compounds, which converts pollutants dissolved in water into gases and/or biodegradable or innocuous species, and without generating waste.

HYK plant rental

Hydrokemos offers the possibility to test HYK technology directly at the customer’s installations thanks to our easy to install and operate HYK plug & play containerized modules. Depending on the performance obtained and the customer’s needs, we can offer a more adjusted operating and investment cost.

HYK plug & play modules are also offered on a long-term lease/rental basis to avoid investment costs for the customer

HYK technology is patented by Hydrokemos and endorsed by the European Commission in the Horizon2020 project.

All the water is used. No waste is generated. That’s why HYK technology is considered a clean and environmentally friendly technology.
