Turbidity - Wikipedia

For many mangrove areas, high turbidity is needed in order to support certain species, such as to protect juvenile fish from predators. For most mangroves along the eastern coast of Australia, in particular Moreton Bay, turbidity levels as high as 600 Nephelometric Turbidity Units (NTU) are needed for proper ecosystem health.

5.5 Turbidity | Monitoring & Assessment | US EPA

Turbidity is a measure of water clarity how much the material suspended in water decreases the passage of light through the water. Suspended materials include soil particles (clay, silt, and sand), algae, plankton, microbes, and other substances. These materials are typically in the size range of 0.004 mm (clay) to 1.0 mm (sand).

High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.

Steam Boiler Questions and Answers

Question: Boiler drum level control goes haywire We are having 100 tones FBC boilers. Frequent problem observed is that whenever there is sudden load change the boiler drum level control goes haywire leading to tripping of boiler and turbine on drum level low or high. Our drum level control is 3-element control in auto mode. Answer:

Controlling TDS in the Boiler Water | Spirax Sarco

For boiler water, however, a hydrometer can be used to obtain an approximate measurement of the dissolved solids, since for boiler water each increase of 0.000 1 relative density at 15.5°C is approximately equal to 110 ppm.

The importance of pH in steam-boiler water - Heating Help

It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If its higher than that, the water wont corrode metal, but it may begin to foam, and thats not good. Hold that thought for a moment.

Boiler Blowdown - Fact Sheet

controlled by measuring the conductivity of the boiler feedwater. Conductivity is a viable indicator of the overall total dissolved solid concentrations. Typically, blowdown rates range from 4 8 percent of boiler feedwater flow rate, but can be as high as 20 percent with extremely poor quality feedwater.

Shell Boilers | Spirax Sarco

Disadvantages of shell boilers: The package principle means that approximately 27 000 kg/h is the maximum output of a shell boiler. If more steam is required, then several boilers need to be connected together. The large diameter cylinders used in the construction of shell boilers effectively limit their operating pressure to approximately 27 bar.

Boiler Water - an overview | ScienceDirect Topics

Maintaining the pH of boiler water in the range of 911 decreases the rate of corrosion; 9.2 to 9.8 is ideal. In low-pressure steam or hot water heating systems, nitrite or chromate provides a protective film on metal surfaces. Filming amines provide a physical barrier to protect metal from corrosion. They are effective in the pH range of 5.5
