Abstract: A sprayer, comprising: a container, configured to contain liquid; a passage, comprising a first opening, a second opening, a resonator and a mesh, when the liquid is passed through the resonator, the liquid is emitted as a gas; a first optical sensor, configured to sense first optical data of at least portion of the mesh or at least portion of a surface of the container; and a processing circuit, configured to compute a foaming level of the mesh or of the surface according to the first optical data, and configured to determine whether the resonator should be turned off or not according to the foaming level. In another aspect, the processing circuit estimates a liquid level of the liquid but does not correspondingly turn off the resonator. By this way, the resonator may be turned on or turned off more properly and the liquid level may be more precisely estimated.

Abstract: A method for removing a heavy metal from water includes subjecting a microbial solution containing a liquid culture of a urease-producing bacterial strain and a reaction solution containing a manganese compound and urea to a microbial-induced precipitation reaction, so as to obtain biomineralized manganese carbonate (MnCO3) particles, admixing the biomineralized MnCO3 particles with water containing a heavy metal, so that the biomineralized MnCO3 particles adsorb the heavy metal in the water to form a precipitate, and removing the precipitate from the water.
