Organic compounds in water become a problem in drinking water treatment, especially during water disinfection with chlorine, when harmful disinfection by-products like trihalomethanes appear. Water organic matter is the genetic name of the organic compounds in the sediment and wastewater. Removal of organic matter and nutrients from slaughterhouse wastewater by using Eichhornia crassipes and evaluation of the generated biomass composting . of these impurities from the wastewater. Removal of effluent organic matter (EfOM) from a wastewater secondary effluent by aluminum sulfate (alum) coagulation and its effects on haloacetic acid (HAA) formation were studied in the range of alum dose 0–120 mg/L and the pH range 4.0–9.0. The presence of dissolved organic matter (DOM) in wastewater effluents is recognized as the main factor limiting the adsorption of organic micropollutants (OMPs) onto activated carbon. When a solution containing absorbable solute comes into contact with a solid with a highly porous surface structure, liquid–solid intermolecular forces of attraction cause some of the solute molecules from the solution to be concentrated or deposited at the solid surface. Removal of organic matter from wastewater. wastewater treatment because of its performance, stabil-ity, cost, and lifetime [18-20]. Wastewater reuse.
