Design smells indicate the accumulated design debt (one of the prominent dimensions of technical debt). Bugs or unimplemented features are not accounted as design smells. Design smells arise from the poor design decisions that make the design fragile and difficult to maintain. It is a good practice to identify design smells in a software system ...
The solid residue of sewage sludge treatment, which is a secondary phase in the wastewater treatment process, is also called humus. [10] When not judged contaminated by pathogens , toxic heavy metals , or persistent organic pollutants according to standard tolerance levels, it is sometimes composted and used as a soil amendment .
Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process) [1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation.

The development of SMS was funded primarily by The United States Army Corps of Engineers and is still known as the Department of Defense Surface-water Modeling System or DoD SMS. It was later ported to Windows platforms in the mid 1990s and support for HP-UX, IRIX, OSF/1, and Solaris platforms was discontinued.
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
This can cause the resuspension of particles by gases and the release of dissolved nutrients throughout the water fluid, reducing the effectiveness of the clarifier. Major health issues and problems can also occur further down the track of the water purification system, or the health of the fish found downstream of the clarifier may be hindered.
Instead, they indicate weaknesses in design that may slow down development or increase the risk of bugs or failures in the future. Bad code smells can be an indicator of factors that contribute to technical debt. [1] Robert C. Martin calls a list of code smells a "value system" for software craftsmanship. [7]
