This paper outlines analysis methods most relevant to resin acid (RA) in pulp and process mill wastewater in process water. These wood-derived compounds dissolve and disperse in the factory process water, cause mechanical failure, lower the quality of the final product and cause environmental problems in the water system when released as waste water There is. Analysis of RA is usually performed by gas chromatography (GC) in combination with derivatized frame ionization detection (FID), electron capture detection (ECD) or mass spectrometry (MS). However, alternative methods using liquid chromatography (LC) or capillary electrophoresis (CE) have recently emerged. He explained the advantages and disadvantages of various methods including high performance liquid chromatography (HPLC).

Caplenas and Kanarek are reporting on research at the paper pulp factory in Wisconsin, USA. The presence of fecal coliforms and Klebsiella was evaluated by evaluating fresh water supply, recycled water in the factory, treated wastewater and water receiving downstream wastewater. Pretreatment effluent contains fecal coliforms and Klebsiella. Up to 84% of the fecal coliforms (tested by standard test procedures) are indeed Klebsiella. This value reaches 90% with treated wastewater. Wastewater treatment reduces the concentration of "genuine" fecal bacterial contamination, but due to the rapid growth of Klebsiella in the wastewater there is no genuine fecal contamination, but the number of fecal coliforms is high. The origin of Klebsiella can be traced back to the initial pulping stage of plants. Klebsiella keeps wood, bark or soil reservoir
