This chapter presents the study of carbon nanotubes' embedment into porous polymeric membranes for wastewater treatment. Water contaminated by industry and agriculture with heavy metal ions, pesticides, organic compounds, endocrine disruptive compounds, and nutrients has to be efficiently treated to protect against human intoxication. Incidental sludge from industrial wastewater treatment facilities is commonly highly contaminated with toxic compounds. Hence, the need of advanced technologies for water treatment results is huge. Numerous experimental and simulation studies have been carried out in order to find the transport properties of water through carbon nanotubes (CNTs). Membrane bioreactor technology is regarded as a key element of advanced wastewater reclamation and reuse schemes, and can considerably contribute to sustainable water management. The adjustment of the parameters of the immersion precipitation phase separation technique may allow the preparation of quasi-ultrafiltration membranes – the so-called CNT-infiltrated tailor-made membranes – with tuned parameters.
