Solids control is a process used in drilling rigs which use drilling fluid. It involves separating the "cuttings" (drilled material) from the fluid, allowing it to be recirculated or discharged to the environment .
Surface mud systems. In the oil drilling industry, effective solids control can be attributed to the overall performance of all the components of the mud systems.Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining mud systems volume will decrease the chance of equipment failure, unnecessary high mud ...
The solids removed by the shale shaker are discharged out of the discharge port into a separate holding tank where they await further treatment or disposal. Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to ...
The typical control band for the concentration of MLSS is 2 to 4 g/L for conventional activated sludge, or up to 15 g/L for membrane bioreactors. One of the easiest control procedures for activated sludge systems is the Constant Mixed Liquor Suspended Solids method.
When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation. The particulate matter is known as sediment or mud. The water content can vary greatly from field to field.
Solid fuel is dense and burns quite quickly, generating thrust over a short time. Solid fuel can remain in storage for an extended period without degrading or breaking down - a common issue with ...
Some people with type 2 diabetes can control their blood glucose through a combination of a healthy diet and increased physical activity, but many rely on medications to reduce blood glucose ...
Based on these control methods, the amount of settled solids in the mixed liquor can be varied by wasting activated sludge (WAS) or returning activated sludge (RAS). [ citation needed ] The returning activated sludge is designed to recycle a portion of the activated sludge from the secondary clarifier back to the aeration tank.
