100m3/H Multimedia Filter Water Treatment , Sand Filter For Water Purification

100m3/h sand filter system removes suspended solids in industrial wastewater treatment

Carbon steel filter is an indispensable device on the pipeline of conveying medium. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect the valve and equipment Normal use. When the fluid enters the filter cartridge with a certain specification filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is needed, just take out the detachable filter cartridge and reload it after treatment. Yes, therefore, it is extremely convenient to use and maintain.

Carbon steel multi-media filters can be divided into mechanical filters and activated carbon filters, used to remove suspended solids and mechanical impurities in water, and can be used for softening, desalination, electrodialysis, reverse osmosis system pretreatment, rivers, lakes, sea water, etc. For surface water treatment, coagulation equipment can be configured to treat industrial water supply and domestic water. Activated carbon filters can also be used for further purification of tap water to remove trace organics such as odor, taste, color and phenol and some heavy metal ions, and improve drinking water quality .

Working principle of carbon steel filter:

The carbon steel filter uses one or several filter media, under a certain pressure, the original liquid passes through the media to remove impurities, so as to achieve the purpose of filtration. The fillers inside are generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc. The user can choose to use according to the actual situation.

Carbon steel filters mainly use fillers to reduce water turbidity, and intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine odors and some heavy metal ions in the water in the interception area, which is one of the traditional water treatment methods to purify the feedwater.

The general principle of carbon steel filter selection:

1. Import and export path:

In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, and generally the same as the inlet pipe diameter.

2. Nominal pressure:

Determine the pressure level of the filter according to the highest pressure that may appear in the filter line.

3. Selection of the number of holes:

The main consideration is the particle size of the impurities to be intercepted, which is determined according to the process requirements of the medium process. For the particle size that can be intercepted by various specifications of screens, check the following table "Filter Specifications".

4. Filter material:

The material of the filter is generally the same as the material of the connected process pipeline. For different service conditions, you can consider choosing a filter made of cast iron, carbon steel, low alloy steel or stainless steel.

5. Calculation of filter resistance loss

For water filters, the pressure loss is 0.52～1.2kpa under general calculation of rated flow rate
