groundwater discharge Applications

Many fresh water sources have been degraded to toxic levels by the inclusion of industrial, agricultural, and human waste products that have been discharged into the closest body of water, accidentally or deliberately for many years.

The HDD, trenchless and underground construction industry has realized the benefits and economics of recycling drilling fluid and slurry. With increased transportation costs and more stringent environmental enforcements and overall cost containment, the need for recycling is evident in all countries and across the range of trenchless applications. From maxi and mini HDD rigs to microtunneling and pipe jacking, packaged mud recycling units and mud reclaimers are an invaluable asset. The below diagram represents...

Decanter centrifuge is used as the 4th phase solids control equipment after shaker, desander and desilter. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream. The use of decanter centrifuge with the drilling mud is (1) removal fine solids from unweighted fluids (2) selection separation of colloidal and ultra-fine solids from weighted fluids to improve their...

Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water...

Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...
