BP Chemical – Custom Sludge Blanket Clarifier Improves Wastewater Treatment Efficiency
Project Overview
BP Chemical operates multiple facilities worldwide, producing a key precursor for food-grade plastics. During the production process, fine particles enter the wastewater stream. The company needed a reliable way to remove and recover these particles—not only to meet environmental standards but also to recycle valuable materials back into production.
Ambatovy – 250 ft Dia Tailings Thickener Retrofit
Project Overview
Ambatovy is one of the largest industrial undertakings in Madagascar, operating integrated mining and refining facilities for nickel and cobalt production. During processing, tailings ponds are used to store solids generated from refining. To maximize water reuse and minimize wastewater discharge, Ambatovy required a more efficient method to reduce water content in tailings.
Consol Energy — Knight AMD Treatment Facility
Project Overview
The Consol Energy Knight AMD Treatment Facility treats up to 1,700 gallons per minute of acid mine drainage using a proven High Density Sludge (HDS) treatment process. Acid mine drainage often exhibits very low pH values—sometimes near 2.0—and contains dissolved metals such as iron that must be oxidized and removed before discharge.
Fields Point Wastewater Treatment Plant – Rhode Island
Project Overview
As the plant aged, a major retrofit and upgrade of key treatment units became necessary. Following a competitive bidding process, ClearStream Engineering was awarded the project, which initially specified a suction header design for the secondary clarifiers.
