A new type of compact wastewater treatment plant has been developed to provide treatment (without chlorine) up to the level permitted for discharge into municipal wastewater treatment facilities or fishery water bodies. The technological scheme of one of the options of the purification station is described.
The paper describes a method of remote control of oil film thickness on rough sea surface using a laser with tunable wavelength. It is shown that the use of an algorithm for smoothing measurement data allows to accurately restore the thickness of oil films on the sea surface.
