    1. Membrane biofouling remains to be one of the most serious operational problems for MBR applications, which results in permeate flux and water quality decline, trans-membrane pressure (TMP) and operating costs increase, frequent membrane cleaning and replacement necessary
    1. different fouling patterns were observed for replicate MBRs seeded with the same inoculum and maintained under identical operating conditions, with similar levels of biomass, soluble microbial products, and extracellular polymeric substances

      The reactors were not maintained under the same conditions - 1 had backpulsing and the other was subjected to relaxation

    1. achieved only a 10% increase of permeate flux when backpulsing was used in the filtration of a biological wastewater containing a high mixed liquor suspended solids
    1. Figure 2. TMP profiles during the operation of two one-stage MBRs in two phases.

      Fouling seems to happen exponentially once it starts => following a first order reaction. What is the mechanism behind this?

    2. a critical issue in MBR that awaits a technological advancement to solve is membrane biofouling, which leads to high energy consumption and thus high operating costs

    1. Klotho-deficient mice have accelerated aging phenotypes, whereas overexpression of Klotho in mice extends lifespan. Klotho is an anti-aging single-pass membrane protein predominantly produced in the kidney, with shedding of the amino-terminal extracellular domain into the systemic circulation. Circulating levels of soluble Klotho decrease with age, and the klotho gene is associated with increased risk of age-related diseases. The three forms of Klotho protein have distinct functions. Membrane Klotho forms a complex with fibroblast growth factor (FGF) receptors, functions as an obligatory co-receptor for FGF23, which is involved in aging and the development of chronic diseases via regulation of Pi and vitamin D metabolism. Secreted Klotho functions as a humoral factor with pleiotropic activities including regulation of oxidative stress, growth factor signaling, and ion homeostasis. Secreted Klotho is also involved in organ protection. The intracellular form of Klotho suppresses inflammation-mediated cellular senescence and mineral metabolism. Herein we provide a brief overview of the structure and function and recent research about Klotho.
