The activation process eliminates disorganized carbon, exposing the aromatic sheets to the activation agents, and contributes toward the formation of a microporous structure. There are two types of activation: physical and chemical. 2.2.2.1 Physical Activation Physical activation is a two-step process.

So, for the most effective textile ,wastewater treatment,, a two-stage process is necessary in which oxygen is introduced after the initial anaerobic decolorization of the azo dye. Hence, interest is now focused on microbes which can perform high rate of dye decolorization under anoxic/anaerobic/static culture conditions and detoxify the toxic aromatic amines aerobically.

However, ,simulated, runoff or seepage waters from chemically amended and dried MFT were phytotoxic, due to combined levels of salts, naphthenic acids and pH. Phytoremediation of runoff water/ground water seepage from dry-land applied MFT will thus require pre-,treatment, in order to make conditions more favorable for plant growth.

How to effectively remove toxic dyes from the industrial ,wastewater, using a green low-cost lignocellulose-based adsorbent, such as lignin, has become a topic of great interest but remains quite challenging. In this study, cosolvent-enhanced lignocellulosic fractionation (CELF) pretreatment and Mannich reaction were combined to generate an aminated CELF lignin which is subsequently applied …
