Send InquiryIntroduction
The surface load of the inclined tube clarifier tank is also called surface loading rate, overflow rate. Surface load is one of the design indicators of clarifier tanks in water supply and drainage treatment plants. As one of the most common clarifier tanks-inclined tube clarifier tanks-what is its surface load?
Surface load is one of the design indicators of clarifier tanks in water supply and drainage treatment plants. When a suspended particle settles within a theoretical residence time over a distance exactly equal to the depth of the pond, its clarifier rate is called the overflow rate or surface load rate. The dimension is several cubic meters [m3 / (m2 * h)] per square meter per unit time, that is, several meters [m / s] per unit time. The efficiency of a clarifier tank is usually based on the surface load factor, expressed in cubic meters of water flowing per day per square meter of water surface area. When the clarifier speed of the particulate matter is greater than the surface load (Vs> q), it can effectively settle to the bottom of the pond and complete the solid-liquid separation. For a clarifier tank, when the amount of water is constant, the size of the particles it can remove is also constant. Among the particles that can be removed, the smallest particle clarifier rate is exactly equal to the hydraulic surface load of the clarifier tank.
Therefore, the smaller the hydraulic surface load, the more particles can be removed, and the higher the clarifier efficiency; otherwise, the larger the hydraulic surface load, the lower the clarifier efficiency.

Several notes on inclined tube packing in clarifier tank
Microbial slime: Because there is enough oxygen dissolved in the circulating water, suitable temperature and trophic conditions, it is very suitable for the growth and reproduction of microorganisms.If it is not promptly manipulated, it will cause rapid deterioration of water quality, odor, and blackness. Tube packing, cooling and cooling effect is greatly reduced, and equipment corrosion is aggravated. Therefore, it is necessary to control the reproduction of microorganisms in circulating water treatment.
Scale: Because the circulating water is continuously transpiration during the cooling process, the salt concentration in the water is continuously increased, and it is deposited beyond the solubility of some salts. Common scales include calcium carbonate, calcium phosphate, and magnesium silicate. The texture of scale is relatively fine. The honeycomb inclined tube greatly reduces the heat transfer power. The thickness of 0.6 mm scale reduces the heat transfer coefficient by 20%.
Dust: The dust is mainly composed of organic matter, microbial colonies and excreta, sediment, dust, etc. in the water. The texture of the dust is soft, which not only reduces the heat transfer power but also causes corrosion under the scale, shortens the use of the filler of the inclined tube clarifier tank, and shortens the use of equipment life.
