What is Organizational and Business Management? How Do I Manage?

Chaos Theory . As chaotic and random as world events seem today, they seem as chaotic in organizations, too. Yet for decades, managers have acted on the basis that organizational events can always be controlled. A new theory (or some say “science”), chaos theory, recognizes that events indeed are rarely controlled.

Sand filtration

Sand filtration is a relatively simple process. Level of automation. The system is easy to automate. Continuous sand filters only require limited automation (loss of pressure, alarms). In discontinuous sand filters, the rinse cycle must be automated and activated by a measured loss of pressure or on a time basis. References

What is Mixing and Blending? What are Mixers, Blenders, or

Mixing is a critical process because the quality of the final product and its attributes are derived by the quality of the mix. Improper mixing results in a non-homogenous product that lacks consistency with respect to desired attributes like chemical composition, color, texture, flavor, reactivity, and particle size.

Sand control techniques

Several techniques are available for minimizing sand production from wells. The choices range from simple changes in operating practices to expensive completions, such as sand consolidation or gravel packing. The sand control method selected depends on site-specific conditions, operating practices and economic considerations.

Filtration

filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration. The coarser sand in the rapid filters has larger voids that do not fill as easily.

Theory

If a new theory better explains and predicts a phenomenon than an old theory (i.e., it has more explanatory power), we are justified in believing that the newer theory describes reality more correctly. This is called an intertheoretic reduction because the terms of the old theory can be reduced to the terms of the new one.
