Inclined tube, also known as hexagonal honeycomb inclined tube, inclined tube filler, filler honeycomb polypropylene inclined tube, inclined tube filler sedimentation device is developed in a shallow pool theory, widely used in water treatment settling ponds and sedimentation devices. Is currently the most widely used and proven means of a water treatment equipment in the water supply and drainage projects. It is suitable for a wide range of high treatment efficiency, small footprint advantages. Intake Desanding applicable general industrial and domestic water sedimentation, sewage sedimentation, grease and tailings enrichment and other processing, both for new construction but also for the transformation of the existing old pool, it has achieved good economic results. Coal columnar activated carbon: suitable for raw water purification plants, especially in the filtration and purification plant boiler chemical wastewater treatment using chloride brackish water areas, there is a good deal as well as the effect of soil improvement management of the golf course and other projects.

Several studies have now revealed that Lee Let me talk about this haze, the winter will be like cloud formations often non-cloud, Si Wu non-foggy weather, the sky is overcast morning to night, this is the haze weather. The reason why most of the recent regional haze weather continued, the main reason for the formation of this kind of weather is industrial, automotive exhaust pollution of the atmosphere caused. With the prosperity and development of industry and population, people around the world consume more and more energy. The main energy supply comes from fossil fuels such as coal, oil and gas, other new energy sources such as nuclear, solar, wind, tidal and geothermal resources, due to the constraints of various conditions, it can not replace the existing fossil fuel the main system. Therefore, the use of fossil fuels have brought air pollution cause for concern, how to control this kind of pollution, coal columnar activated carbon adsorption with its unique can solve this kind of pollution.
