In traditional filtration processes, equipment such as diatomaceous earth filter machines have many drawbacks, such as large liquid loss, difficult operation, and easy blockage of sewers. The emergence of soilless filter machines has brought a new solution to the field of filtration.

The soilless filter adopts advanced enhanced membrane separation technology. Taking the ceramic membrane shear flow filter as an example, the high-speed rotating cross flow filtration method effectively prevents membrane blockage. The membrane rotates at high speed along with the shaft driven by the motor, generating a high shear rate on the surface of the filter disc to form a swirling sweep flow, making the filter cake layer on the surface of the filter disc very thin or even exposed, avoiding the formation of a blocking layer, and thus not hindering the permeate flow. This unique filtration method results in slow attenuation of membrane flux, minimal influence from feed concentration, and long continuous and stable filtration time.

The soilless filter has significant advantages. In terms of energy consumption, it performs excellently. For example, the power consumption of ceramic membrane cutting flow filter is one-third of that of tubular ceramic membrane, saving about 30% -40% energy compared to traditional filter, which saves a lot of energy costs for enterprises. In terms of filtration effect, it can achieve double-sided filtration, increase the effective filtration area within the equivalent volume, and improve the filtration efficiency and quality. At the same time, the soilless filter machine does not require filtering media, reducing wastewater treatment costs and greatly saving production costs. In addition, it also has an automatic cleaning function, which is fast and efficient, further improving the production efficiency of the enterprise.

The application field of soilless filter is very wide. In the food industry, it can be used for juice residue concentration and filtration, solid-liquid separation of red wine residue, solid-liquid separation of soy sauce industry, etc. Taking the soy sauce industry as an example, soy sauce treated with membrane separation has differences in physical and chemical index detection and sensory evaluation compared to diatomaceous earth filtration, resulting in better preservation of flavor. In the biological fermentation industry, it can be used for residue, precipitation, filtration and concentration; In the spice industry, solid-liquid separation and concentration filtration can be achieved; In the dairy industry, it can be used for filtration, concentration, and sterilization. In addition, it is suitable for concentrated filtration of high concentration and high solid content materials, with a solid content that can be concentrated to over 90%, solving the problem of tubular ceramic membranes being unable to filter and concentrate high concentration materials.

The soilless filter also has the characteristic of intelligence. By using PLC to control and interlock the opening and closing status of each module, automatic monitoring of temperature, turbidity, liquid level, flow rate, pressure, etc. can be achieved, ensuring safe operation and stable performance. At the same time, there are pressure overload protection, filter overpressure overload shutdown protection and pressure relief device, filter cut-off low-pressure shutdown protection, etc., to ensure the safe operation of the equipment. Its unique structural design also makes equipment maintenance economical, convenient, and safe.

With the continuous advancement of technology, the performance and application fields of soilless filters will continue to expand. It has gradually become the mainstream equipment in the filtration field with its advantages of high efficiency, energy saving, and environmental protection, providing strong support for the production and development of various industries.
