Wastewater Treatment
Industrial Wastewater Treatment and Heavy Metal Recovery
Industrial wastewater streams often contain toxic heavy metals such as lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni), zinc (Zn), and copper (Cu), which pose serious risks to human health and the environment. At Hydrolyz, we develop and implement advanced hydrometallurgical and physicochemical treatment processes including precipitation, adsorption, ion exchange, membrane separation, and electrochemical techniques for the effective removal of these contaminants. Beyond removal, our expertise lies in the recovery and recycling of valuable metals from wastewater, enabling their reintegration into industries such as plating, battery manufacturing, alloys, and fertilizers. This not only reduces environmental pollution but also promotes circular economy practices by converting waste streams into resources, while minimizing the cost burden of wastewater management.
Electro-Assisted Cementation Process
The Electro-Assisted Cementation (EAC) process is an advanced hydrometallurgical technique that combines conventional cementation with an applied electrical potential to accelerate the removal and recovery of less noble metals from aqueous solutions efficiently and selectively.
Electro-Oxidation Process
Electro-Oxidation (EO) process is an advanced water treatment technique in which an electrical current generates highly reactive oxidizing species, such as hydroxyl radicals, at the anode to degrade organic pollutants and remove contaminants from wastewater efficiently and sustainably.

Hydrolyz Assists in Water Recycling
Water recycling is a critical strategy for sustainable resource management across various industries, including mining, chemical, textile, fertilizer, electroplating, and metallurgical operations. By treating and reusing process water, industries can significantly reduce freshwater consumption, lower operational costs, and minimize environmental discharge. In mining and metallurgical processes, recycled water can be used in ore processing, leaching, and cooling systems. In the textile and chemical industries, water recovery supports dyeing, washing, and reaction processes while reducing pollutant load. Electroplating and fertilizer operations benefit from reclaimed water in rinse baths and solution preparation. Effective water recycling requires integrated treatment solutions, including filtration, precipitation, membrane separation, and chemical conditioning, combined with regular metallurgical and chemical analysis to ensure water quality meets process specifications. Implementing water recycling not only enhances environmental compliance but also contributes to circular economy practices and sustainable industrial growth.

Electro-Assisted Cementation (EAC) Process For the Recovery of Valuable Metals
Hydrolyz has developed an innovative Electro-Assisted Cementation (EAC) process to efficiently remove and recover heavy metals such as Copper, Nickel, Cobalt, Manganese, and Cadmium from industrial wastewater. Unlike conventional cementation, which relies solely on the galvanic displacement of less noble metals using a more electronegative metal like Zinc, the EAC process integrates an electrochemical driving force to accelerate reaction kinetics and improve selectivity. This approach not only enhances metal removal efficiency but also reduces excess zinc consumption, minimizes sludge generation, and enables controlled recovery of valuable metals in a more sustainable and cost-effective manner. Our established EAC technology demonstrates clear advantages over traditional methods and is well-positioned for industrial adoption in wastewater treatment and resource recovery applications.
Electro-Oxidation (EO) Process in Water Treatment
Electro-oxidation (EO) is an advanced electrochemical technique used for the degradation of organic pollutants and removal of heavy metals from wastewater. In this process, an electrical current is applied between an anode and cathode, generating strong oxidizing species such as hydroxyl radicals (•OH) at the anode surface. These reactive species oxidize and break down persistent organic compounds, dyes, and pharmaceuticals, converting them into less harmful substances like water and carbon dioxide.
Electro-oxidation is highly efficient, environmentally friendly, and adaptable, offering several advantages:
Non-selective degradation of a wide range of organic contaminants.
Minimal chemical addition, reducing secondary pollution and sludge generation.
Scalability for industrial applications, including textile, chemical, metallurgical, and electroplating industries wastewater.
Integration with other treatment methods, such as filtration, sedimentation, or membrane processes for enhanced overall efficiency.
By combining high treatment efficiency with low environmental impact, electro-oxidation provides a sustainable and modern solution for industrial and municipal wastewater treatment.
