Aquaculture sewage has high concentration of organic matter, many suspended solids and dark chromaticity, which results in high concentration of NH3-N and a large number of pathogenic bacteria because it contains a large number of animal faeces. 

The pollutants in the sewage mainly exist in the form of solid and dissolved carbohydrates, which makes the sewage show high BOD5, CODcr, SS and chromaticity. At the same time, the sewage can be biochemically better, and it contains a lot of N, P and other nutrients. 

As the solid residue in the sewage is mainly organic matter, it is necessary to strengthen the pretreatment, carry out solid-liquid separation and reduce the load of subsequent treatment. 

In view of the fact that the aquaculture industry is currently a low-profit and high-risk industry, the company actively develops new treatment processes to reduce the total investment in equipment and save every penny on the premise of meeting the sewage discharge standard. 

The reliability of the vortex fan for rural sewage treatment is high. When the use situation changes, the machine can still operate safely. 

In addition to the impeller, the high-pressure blower has no other action, so the high reliability is almost maintenance-free. 

The products are favored by many customers all over the world. 

Purifying trough blower


1. It has the dual functions of blowing and suction, and can be used both in one machine and in the air. 

2. Running with little or no oil, the output air is clean. 

3. Compared with centrifugal fan and medium pressure fan, its pressure is often more than ten times that of centrifugal fan. 

4. If the pump body is die-cast and shockproof installation footings are used, then its requirements for installation foundation are also very low, and it can even operate normally without fixed footings, which is very convenient and saves installation costs and installation cycle. 

5. Compared with other types of fans, such as Roots fan, the noise of its operation is lower, and the higher the power is, the more obvious it is, and the above 5.5KW will be shown. 

6, maintenance-free use; its wear and tear parts are only two bearings, during the warranty period, basically do not need maintenance. 

7. The mechanical wear of the high pressure fan is very small, because there is no other mechanical contact part except the bearing, so of course, the service life is also very long, as long as it is under normal use conditions, there will be no problem for 3 ~ 5 years.
