Wastewater treatment processes are employed to remove these particulates, and also adjust the pH of the wastewater within acceptable limits. ACS offers a complete range of solutions, products and equipment designed to treat the wastewater generated from varying concrete production processes.
Dec 28, 2000· Water and wastewater treatment plants provide a severe environment for concrete. Concrete tanks can be subjected to wet-dry cycling, freeze-thaw cycling, chemical attack and abrasion. Even high quality concrete will deteriorate under these harsh conditions (but at a slower rate than poor quality concrete).
Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can then be used for other purposes.

Precast concrete manufacturers by nature are problem solvers, whether they are providing an innovative and cost-effective alternative for a large-scale cast-in-place project or redesigning production operations to minimize waste.
Wastewater treatment - Wastewater treatment - Primary treatment: Primary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars. They block floating debris such as wood, rags, and other bulky objects that could ...
Hazardous-waste management - Hazardous-waste management - Treatment, storage, and disposal: Several options are available for hazardous-waste management.
