fosses de décantation de laitance washwater/slurry settling ponds/pits Explanation: "laitance" is two things (in the concrete context): 1) a solution of cement and water used for various construction purposes (cement slurry) 2) that part of the concrete matrix which rises to the surface as a thin, milky liquid. Basically undesirable. Called "laitance" in English. By extension, it also refers to the waste product from rinsing of concrete mixers, etc. and/or from removal of concrete laitance, dust, or actual concrete (scabbling, etching, etc.). Like the above forms 1 and 2, this is thin milky liquid containing cement (concrete washwater). Given the environmental harm this washwater could do, it is desirable for it to be collected and treated, starting with settling to remove the larger particles. An operator must ensure that no water used in concrete batching or cement product manufacturing is discharged from the premises until - (a) it has been - (i) through a silt trap; or (ii) contained in a SETTLING POND for long enough to allow all particulate matter to settle out; and (b) if the water is likely to contain hydrocarbons, it has been through an oil interceptor. 12. SLURRY PITS, SETTLING PONDS, silt traps and oil interceptors ["slurry" is used here in exactly the same way as "laitance" is used in French] (1) An operator must not allow settled material in a SLURRY PIT to - (a) dry out (except when the pit is dried out to allow the settled material to be removed); or (b) be higher than 30 cm below the top of the slurry pit walls. (2) An operator must ensure that a SETTLING POND is large enough to contain all water which might drain into it for long enough to allow all particulate matter to settle out. (3) An operator must ensure that slurry pits, settling ponds, silt traps and oil interceptors are maintained, and emptied or cleaned as often as necessary, to ensure their efficient operation. 13. Disposal of waste An operator must ensure that all waste created during concrete batching or cement product manufacturing (including material removed from slurry pits, settling ponds, silt traps and oil interceptors) is - (a) recycled; or (b) disposed of at an appropriate landfill site or waste treatment facility the occupier of which holds a licence under Part V of the Act in respect of that site or facility. [http://members.westnet.com.au/web/anti-corruption/Cement-Pro...] Concrete or Cementitious WASHWATER CONCRETE OR CEMENTITIOUS (mortar, grout, plaster, stucco, cement, slurry) WASHOUT WASTEWATER is caustic and considered to be corrosive with a pH near 12, essentially the same as Liquid Drano, Ammonia or other household cleaning detergents. The primary ingredient in ready mixed concrete is Portland Cement, which consists of Portland Cement Clinker, Calcium Sulfate, Calcium and Magnesium Oxide, metals and trace elements of potassium and sodium sulfate compounds, chromium compounds and nickel compounds. CONCRETE WASH WATER is basically a SLURRY OF FINE PORTLAND CEMENT PARTICLES IN WATER, also called suspended solids when in water. When illegally discharged into a fish-bearing waterway, it will clog fish gills; reducing the amount of oxygen they receive which can ultimately lead to death |
