“Diatomaceous Earth Filter: an efficient, stable and economical solution for liquid filtration”

The diatomaceous earth filter is composed of a cylinder, a wedge-shaped filter element, and a control system.

The diatomaceous earth slurry enters the cylinder under the action of the pump, and the diatomaceous earth particles are intercepted by the filter element and attached to the surface, forming a pre coating. When the liquid to be filtered passes through the pre coating, larger impurity particles are trapped on the outer surface of the pre coating, and smaller impurities are adsorbed and intercepted in the small pores of the diatomaceous earth itself, thus obtaining micrometer level liquid and completing the filtration. After filtration, use water or compressed air for backwashing to wash away the contaminated diatomaceous earth. Impurities and failed diatomaceous earth on the surface of the filter element will fall off and be discharged from the filter.

Performance advantages:

1. Efficient filtration: It can remove extremely fine particles and achieve extremely high clarity of the filtered liquid, reaching micron level, meeting the industry standards for extremely strict water quality requirements.

2. Stable and reliable: Under normal working conditions, the filtration performance is stable and not greatly affected by factors such as liquid flow rate and temperature. It can operate continuously for a long time, providing reliable support for the production process.

3. Strong adaptability: Suitable for filtering liquids of various properties, whether acidic, alkaline, or neutral, it can achieve good filtering effect. Meanwhile, the amount of diatomaceous earth added and filtration process parameters can be flexibly adjusted according to different filtration requirements.

4. Economic and environmental protection: Compared with other high-precision filtration equipment, the operating cost of diatomaceous earth filters is relatively low. Diatomaceous earth resources are abundant, relatively inexpensive, and generally do not introduce new pollutants during the filtration process. The filtered diatomaceous earth filter cake can also be partially recycled through appropriate treatment.

Development trend:

With the continuous advancement of technology and the increasing demand for environmental protection, diatomaceous earth filters are also constantly innovating and developing. On the one hand, by improving the structure and material of the filtering elements, the filtration efficiency and service life can be further enhanced; On the other hand, developing more intelligent control systems to achieve precise monitoring and automated operation of the filtering process, reducing labor costs. At the same time, research is being conducted on new modification technologies for diatomaceous earth to improve its adsorption performance and filtration accuracy, in order to meet the constantly emerging high-end filtration demands.

Diatomaceous earth filters play an important role in many fields due to their advantages of high efficiency, stability, and economy. With the continuous upgrading of technology and the expansion of its application scope, it will continue to occupy an important position in the future filtration market, making greater contributions to the development of various industries and environmental protection.
