Treatment of oily wastewater and coking wastewater with chitosan

Due to the cationic characteristics of chitosan with high charge density, it can be neutralized with electronegative groups. Therefore, chitosan molecules can adsorb residual waste oil. Yuda uses chitosan to treat oily wastewater from palm oil plant. When the PH value is 4-5, the oil removal rate of oily wastewater with oil concentration of 2000mg/L can reach 97%. In addition, we use chitosan quaternary ammonium salt as a flocculant to treat refinery wastewater. When the mass concentration is 5mg/L, the ideal oil removal and turbidity reduction effect can be achieved. Yuda cooperates with coking coal group to use modified chitosan flocculant to decolorize coking wastewater with flocculation rate of 60% and remove iron ion with 90%. It has been fully proved that chitosan is a good natural and stain free flocculant.
