Concentrated Solar Power Thermal for Biosolid Drying

Sludge is a by-product from cleaning municipal sewage at waste water treatment plants. Removing the water from the sludge creates dry biosolids with reduced weight, and they can be transported at significantly lower costs than wet sludge. Moreover, these biosolids can then be used as fertilizers in agriculture. Since the [...]

Concentrated Solar Power for wastewater treatment

A novel 98 kW Heat2Hydro – Rackam test wastewater treatment system in Surprise, Arizona, was started up this summer. This is a test project which demonstrates the use of solar energy to efficiently dry the sludge byproduct generated from wastewater treatment process and to evaluate the effectiveness of this solution.
