W-DRY
In wastewater treatment plants, sludge generation and disposal account for a significant share of operational costs. In this context, drying is a technically and economically viable solution for reducing volume and lowering disposal costs through moisture removal. W-DRY dryers are designed for high-efficiency moisture removal from semi-solid streams. Operating at low temperatures (30–40 °C), they minimize odors, improve operational safety, and preserve the physicochemical characteristics of the material.
Applications
- Food industry, Beverage industry, Textile industry, Dairy, Paper & Pulp

Advantages
- Reduces sludge moisture by up to 20%
- Significant reduction in the volume of sludge generated (depending on the characteristics of the incoming sludge)
- Low temperature operation (30–40 °C)
- Reduced volatilization of odorous compounds
Greater operational safety due to not working with high temperatures.
- Lower drying cost (R$/kg H2O removed) compared to conventional dryers.
