In order to investigate the cause of the widespread clogging problem, this study examines the IRB microbiology and inorganic water chemistry of bore water across two selected sub-regions of the Limestone Coast. Groundwater was analysed from a range of production bores with no, unknown or known clogging problems.

Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6.

Abstract. Guizhou, China, is known for the abundance of subterranean drainage systems with sinkholes. Sinkholes may develop when acidic water starts to dissolve the surface of bedrock or bedding planes. The dissolution characteristics of limestone play a crucial role in the development of sinkholes. The main objective of this …

Wastewater system on the verge of clogging. Everyone knows when a wastewater system becomes clogged, things can end badly. In the worst case scenario, wastewater cannot drain properly and the brown sludge pushes back into the connection points or spills out of floor openings actually intended as drains.

A key component of Drake's dry-process manufacturing is efficient material flow. Excessive rain in the months of January through March caused the limestone being extracted from the nearby quarry to have elevated moisture levels. Not only does the rain cause standing water, but the limestone is also wetter coming out of the ground.

For this reason, pinch valves have been used in mining applications on very coarse slurries for the past 30 years. With any mineral-based slurry, pinch valves are a very viable option for protecting against abrasion. A pinch valve also offers protection against clogging or jamming that can occur with other valves in lime slurry service.
