Activated Carbon Filter Installation (HEPA Filter Installation)

Activated carbon is used more in life, especially to solve many water treatment problems, such as removing impurities in water, organic matter or deoxygenation. To make the activated carbon to play a hundred percent of the role, the choice of activated carbon filter size is very important, if you choose the wrong size of activated carbon filter, its function will be greatly reduced, so we must choose a good.

Activated Carbon Filter

Activated carbon filter is a more commonly used water treatment equipment, as a pre-treatment of water treatment desalination system can adsorb the residual chlorine that can not be removed in the previous filtration, which can effectively ensure the service life of the latter equipment, improve the quality of the water and prevent pollution, especially to prevent the latter reverse osmosis membranes, ion exchange resins, etc., the free state of the residual oxygen toxicity of the contamination. The adsorption capacity of activated carbon is directly proportional to the contact time with water, the longer the contact time, the better the water quality after filtration. Note: The filtered water should flow out of the filter layer slowly. New activated carbon should be washed and cleaned before the first use, otherwise ink-black water will flow out. Activated carbon in the filter before loading, should be in the bottom and the top of the sponge with a thickness of 2 to 3 cm, the role is to prevent algae and other large particles of impurities to penetrate into the activated carbon after 2 to 3 months, if the filtering effect declines should be replaced with new activated carbon, sponge layer should be replaced regularly.

When installing the activated carbon filter in the water treatment system, the flow rate and the concentration of pollutants in the water must be considered. Reasonable installation is to ensure that the gas-water mixing vessel is not under pressure, not "back to the water", the key to normal use, absolutely to meet the design requirements, that is, Q out of the "Q into the water + Q into the gas, this condition is not only in the normal situation to ensure that, but also in special circumstances (such as power outages, water shutdowns, etc.) should be reached basically, the necessary debugging can not be less, otherwise The previous work is lost. If the pressure at the point of injection is not greater than the mixer outlet pressure, equivalent to gravity injection mode, installation and commissioning is simple. On the contrary, the mixer can be considered at the inlet, the use of high-level tanks to do Q into the water source can also be added at the outlet of the mixer, that is, the point of injection of water jets, or both.

Installing the right size of activated carbon filter is an important part of the process. No matter what is suitable or not, and the activated carbon filter is the same, in order to make it play the most effective, we need to understand where it is located in the environment, to filter the items to be contaminated degree and so on. After the above introduction of activated carbon filters and suggestions, I believe we can more reasonably choose the size of the activated carbon filter.

High Efficiency Filter Installation

Do 100,000 clean room purification project companies know that the installation and sealing of high-efficiency filters directly affect the purification effect of the clean room. Then how to install high efficiency filter? Let Au Xuan purification to give you a generalization of 100,000 clean room installation of high-efficiency filters.

Fixed high-efficiency filter skeleton material should be flat and have good rigidity, fire prevention and no dust. Aluminum alloy skeleton is light in weight, and general steel (channel steel, angle steel, T-shaped steel, I-beam and steel plate) skeleton should be prevented from rusting, and the surface layer should be galvanized. Construction and installation of the surface is still inevitably damaged, but also with the paint for local repair, can also be used directly on the surface of the steel skeleton spraying high-strength ageing-resistant paint. No matter what kind of skeleton is used, attention should be paid to the connection between the skeleton components to be tight and smooth, otherwise it will make the interface of the grass-roots level where the high-efficiency filter is installed uneven, which will directly affect the sealing quality.

There are mainly the following ways to install high-efficiency filters in a class 100,000 clean room.

1, installed in the duct, in the use of local hole plate top feeding, diffusion type top feeding and louvered air outlet side feeding clean room, high efficiency filters are usually installed in the technical sandwich or the duct inside the duct. In this way, if there is leakage in the installation, it can only leak into the technical sandwich or the duct without affecting the cleanliness of the room.

2, in the ceiling air supply outlet installation, this way is divided into the top mounted (installed above the ceiling) and the bottom mounted (installed below the ceiling) two kinds.

In the vertical unidirectional flow cleanroom, the installation of high-efficiency filters also have the upper and lower mounted points. In the horizontal unidirectional flow clean room, high-efficiency filters are best installed in the air supply static pressure room, which not only facilitates sealing, leakage detection and plugging, but also when the clean room purification and air conditioning system for intermittent operation, but also to avoid the filter and its pressure frame on the accumulation of dust to affect the cleanliness of the room.

The main sealing methods for the installation of high-efficiency filters are: a. Sealing gasket method, the current domestic sponge latex plate are open hole type, not suitable for high-efficiency filter installation of the sealing material, sponge rubber plate is closed hole type, as the sealing material has a good airtightness. b. Liquid tank sealing method, which is the use of inert liquids in the tank to be filled with the sealing method. This method has high airtightness, simple construction, easy to install.

How to install the high efficiency filter in the 100,000-class clean room you learned? These two methods are very good, you can choose the method suitable for their 100,000 clean room installation Oh.
