Tratamento de água poluída

Discover how CHIWATEC’s reverse osmosis and ultrafiltration wastewater treatment systems provide sustainable, cost-effective, and energy-efficient solutions for water reuse. Our advanced technologies help industries and municipalities recover clean water from wastewater while protecting the environment and reducing operational costs.

With global freshwater resources becoming increasingly scarce, effective wastewater treatment and reuse have become critical for industrial, agricultural, and municipal sustainability.
In China, approximately three-quarters of freshwater is consumed for industrial and agricultural purposes, such as cooling, irrigation, and power generation. This immense demand places pressure on limited water sources, especially in regions that depend heavily on irregular rainfall.

By applying treated wastewater for non-potable uses, industries can reduce dependence on freshwater and create a consistent, cost-effective water source. Treated sewage can be reused for irrigation, industrial cooling, river replenishment, and greywater applications in both residential and commercial settings.

CHIWATEC specializes in high-efficiency water treatment systems, combining ultrafiltration (UF), reverse osmosis (RO), and UV sterilization to achieve superior purification and consistent performance. Our wastewater treatment systems are designed to meet the unique challenges of various industries and water compositions.

For irrigation and industrial water reuse, turbidity and suspended solids are major concerns. These particles not only damage filtration membranes and piping systems but also hinder disinfection processes that prevent bacterial growth.

CHIWATEC’s Equipamento de purificação de água UF provides stable low-turbidity performance, even when influent water quality fluctuates. The result is clean, particle-free water suitable for safe reuse in agricultural and industrial applications.

High concentrations of inorganic salts and heavy metals—such as nickel, mercury, and zinc—can also be harmful to crops and soil. Our Reverse Osmosis Systems effectively remove these toxic substances, ensuring that treated wastewater is both safe and compliant with international standards.

Microbial contamination is one of the most persistent challenges in wastewater reuse. While chlorine is a common disinfectant, it is costly, corrosive, and harmful to plants at elevated levels.

CHIWATEC’s UV Sterilizer Systems offer a chemical-free solution for wastewater disinfection. Using ultraviolet light, these systems instantly destroy bacteria, viruses, and other microorganisms without altering water chemistry or leaving any toxic residues. This ensures safe, eco-friendly, and low-maintenance water sterilization for both industrial and municipal applications.

Our systems are widely used across multiple sectors, including:

• Treated Sewage Effluent (TSE) Reuse – For irrigation, landscaping, and industrial processes.
• Rainwater Harvesting and Treatment – For storage and reuse in non-potable applications.
• Industrial Wastewater Recovery – For cooling towers, rinsing, or manufacturing reuse.
• Disinfection and Turbidity Control – To meet strict health and safety regulations.
• Greywater Recycling – For residential and commercial reuse, reducing freshwater demand.

By reusing treated wastewater, industries and municipalities can reduce water costs, minimize environmental impact, and support long-term water sustainability goals.
