Product Name: SDL Series Manual Water Filter

Product Usage:

This filter is mainly used for coarse and fine filtration of cooling water for power plant auxiliary equipment, industrial circulating water, fire-fighting water, detergent and other similar suspensions.

working principle:

The filtering and backwashing driving force of the machine is provided by the raw water pressure head or pump head. The pressure in the system filter chamber remains basically constant, and the liquid flows outward from the inner cavity of the filter element. The solid impurities carried by it are intercepted on the inner surface of the filter medium, causing an increase in the pressure difference between the inner and outer chambers and gradually increasing the filtration resistance. When the inlet pressure reaches 0.6 MPa, lift the positioning pin, rotate the operating rod to the next positioning pin hole, lower the positioning pin, open the discharge valve at the outlet of the discharge pipe, and perform backwash discharge (usually for about one minute, depending on the industrial and mining situation). Repeat this process until one loop ends.

Performance characteristics:

Good backwashing effect: This machine uses its own filtered clear liquid to backwash the filter element, without the need to remove the filter element for cleaning, nor does it require a separate cleaning system. Due to the uniform arrangement of gaps in the filtration chamber, solid impurities are trapped on the surface without blocking the gaps, resulting in good backwashing effect.

Continuous water supply: Multiple filtration chambers work simultaneously inside the tank of this machine. During backwashing, each filtration chamber is cleaned one by one, while the other filtration chambers are still continuously filtering, ensuring a continuous supply of filtrate.

Low washing water consumption: When this machine backwashs, only one to two filter chambers are cleaned at the same time, accounting for more than ten to twenty percent of the entire filtration area. Therefore, the sewage water consumption is less than 5% of the design flow rate, which is more than twice that of traditional structures.

Large filtration area: Due to the arrangement of multiple filtration chambers inside the tank, the container space is fully utilized, and the effective filtration area can reach more than 8 times the inlet area, which is about twice that of traditional structures.
