Water is a major component in paper mill.
Therefore, the water treatment process is also very important, especially the treatment of waste water.
Waste generated by the paper mills as the categories of hazardous waste that is not discharged directly into rivers.
We process the waste water at IPAL (=Instalasi Pengolahan Air Limbah)
