Treatment and disposal of sludge and wastewater from a variety of sources, both industrial and municipal, is a high-demand industry with terrific growth potential. With the pressure of EPA regulations, fewer options at landfills, increasing transportation costs and documentation, the demand for energy-efficient, automated, continuous drying processes and equipment is at an all-time high. The key to success is know-how. All sludge is not created equal. There is a need for careful analysis and state-of-the-art equipment.
