Sand Extraction 1. IntroductionGreenFacts

 · Sand mining has led to deepening and widening of the Lake Poyang channel the largest freshwater lake in China and a biodiversity reserve of exceptional importance and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake s water levels which reached a historically low level in 2008.

Discharge into drains systems Colubris Cleantech

Discharge into sewers mostly requires the industrial discharger to meet the standards set by the local sewage works. Depending on the capacity and technology used at the local sewage works a simple screening system may be sufficient. However mostly it requires to take out all solids fat greases and 50-80 of the BOD/COD.

Septic Tank Drainage Fields Soakaway Sewage System

 · Septic tank drainage fields are an integral part of a septic system. Often incorrectly called soakaways a drainage field is much more than just a soakaway. A drainage field is a specifically designed arrangement of perforated pipework laid in trenches to allow the effluent to filter into the ground. They are designed to ensure aerobic contact

 · The formula for calculating the total trench length contained in the system is L = Q x T / 200 where T is the percolation rate of the design sand. Contractors/suppliers of sand have their sand tested and have a soil data sheet with this number usually in a range. The highest number needs to be used where a range is provided.

Above Ground Mound SoakawaysSewage Treatment Plants

The effluent from the septic tank or preferably sewage treatment plant (the mounds tend to become clogged if septic tanks are used) is drained to a pumping station which pumps it up into the drain-pipes in the absorption bed of the mound. The effluent then drains through graded layers of sand/gravels to neutralise the pollutants before draining both vertically and laterally into the topsoil

Why Aeration Is Central To Sewage Treatment Wastewater

 · During wastewater treatment over 60 of power requirements go towards aeration. And as aeration is central to the level of efficiency in processing wastewater for disposal it is essential that you have the technology and equipment to meet these demands. Find out more on how Howden lead the way in smart aeration.
