(1) On the fire. 1) activated carbon is not included in the dangerous category, but flammable. After the fire does not occur with flame burning, but smoldering. 2) activated carbon does not spontaneous combustion, in the air may be on fire, and gasoline, diesel and other mixed, can cause combustion. 3) activated carbon combustion if […]

(1) treatment of water and activated carbon contact time of not less than l0min. (2) the height of the activated carbon layer is generally 1. 2-2.5m. (3) operating velocity υ = 7 ~ l0m / h, the design must first consider the choice of a reasonable filtration rate. Under certain carbon layer thickness conditions, the […]

(1) activated carbon loaded with filtered water after washing and backwashing (no residual chlorine of filtered water). (2) drain to the filter surface 10-15 cm, with 3% to 50% HCI soak 12-24h. (3) the discharge of waste acid, with water is washed into the water alkalinity equal; in the cation exchanger after the activated carbon […]

Industrial water treatment is usually used fixed-bed type activated carbon filter, and its structure is the same as the general pressure filter to remove organic matter and residual chlorine effect depends on the height of the activated carbon layer, the volume. Figure 2-39 shows the change of the active carbon layer System design of activated […]

Filter at any time to carefully check the connection is strong, the use of various components is good, abnormal circumstances should be promptly notified maintenance personnel to carry out maintenance. To pull plate car, sprocket chain, bearings, piston rod and other parts to be regularly checked to make the parts to keep clean, good lubrication […]

The principle of the filter is the use of porous media, from the fluid (liquid or gas) to remove contaminants, the fluid to achieve the required level of cleanliness. Filters are often thought of as simple screens or screens, and filtration or separation is carried out on a surface. This is the way in the […]

Filter is the use of one or several filter media, under a certain pressure to the turbidity of water through a certain thickness of the granular or non-granular material, which effectively remove suspended impurities to clarify the process of water, commonly used filter There are quartz sand, anthracite, manganese sand, mainly used for water treatment […]

The filter is related to the characteristics of the fluid. For example, the fluid viscosity and chemical / ionic components, the greater the viscosity of the fluid under the same pressure conditions, the slower the flow of fluid and the membrane has more contact between the filter better; another example, the fluid and membrane mixing […]
