What methods can be used to remove the sediment in the coarse salt turbid liquid and what instruments are used? The experimental supplies are: iron frame (with iron ring ),Tray balance,Cylinder,Beaker,Glass rods,Spoon,Funnel,Pan,Alcohol lamp,Pliers,Glue head dropper,Filter paper,Scissors,Matches,1.(1) weighing: before weighing, put the swim code of the balance at the 0 scale of the scale,Check whether the balance is balanced.If imbalance,Need to adjust,The balance can be weighed only after balance.(2) Dissolution: Pour the appropriate amount of water into the beaker,Add coarse salt to the water with a medicine spoon,Stir with a glass stick,Until the coarse salt is no longer dissolved.2.(1) gently lean the glass stick against the three-layer filter paper.(2) the beaker containing the liquid to be filtered is close to the glass rod,Slowly pour the filter to the filter along the glass bar.(3) The turbid liquid to be filtered should always be lower than the edge of the filter paper.3.(1) p
A new type of filtration equipment The most commonly used method of mechanical filtration sewage treatment,Depending on the filter media,Mechanical filtration equipment is divided into two categories: Particle Media filtration and fiber filtration,Particle Media filtering mainly uses granular filter materials such as sand and gravel as filter media,Through the adsorption effect of particle filter material and the interception effect of pores between sand particles on solid suspended matter in water body, the filtration is realized,The advantage is that it is easy to counterattack,The disadvantage is that the filtration speed is slow,Generally no more than 7 m/h;Less pollution,The core filter layer is only the surface of the filter layer;Low filtering accuracy,Only 20-40 μm,It is not suitable for fast filtration of high turbidity sewage.The high-efficiency asymmetric fiber filtration system uses asymmetric fiber bundle material as the filter material,The filter material is asymmetric fiber,On the basis of fibe
