2. Turbidity - Wikipedia

   en.wikipedia.org/wiki/Turbidity

   Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes.

3. NTU method - Wikipedia

   en.wikipedia.org/wiki/NTU_Method

   NTU method. The number of transfer units (NTU) method is used to calculate the rate of heat transfer in heat exchangers (especially parallel flow, counter current, and cross-flow exchangers) when there is insufficient information to calculate the log mean temperature difference (LMTD). Alternatively, this method is useful for determining the ...

4. Turbidimetry - Wikipedia

   en.wikipedia.org/wiki/Turbidimetry

   Turbidimetry. Turbidimetry (the name being derived from turbidity) is the process of measuring the loss of intensity of transmitted light due to the scattering effect of particles suspended in it. Light is passed through a filter creating a light of known wavelength which is then passed through a cuvette containing a solution.

5. Nephelometer - Wikipedia

   en.wikipedia.org/wiki/Nephelometer

   A nephelometer[1] or aerosol photometer[2] is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam. Particle density is then a function of the ...
