Development of a Prototype of Wastewater Treatment from The Hemodialysis Process Using a Fixed Aerobic Biological Reactor |Biomedgrid

Water is an indispensable resource in our daily activities, which is why it is constantly being recovered and reused through water treatment at the domestic, industrial and hospital levels. Some companies, depending on their waste, are obliged to carry out proper waste management, before being dumped into the drain. In the case of hospitals, there is not only talk of remediating the water but also the excessive spending that some areas handle, such as hemodialysis. Hemodialysis is an expensive treatment that allows patients with kidney failure to have an artificial kidney that is responsible for cleaning their body of toxins, performing 2 sessions of four hours per week where each session uses approximately 300l of water which flows directly into the drain. Therefore, a 70l volume wastewater treatment prototype was developed, using Polyethylene Terephthalate (PET) bottles as support. The 500ml bottles were placed in concentric shapes inside the 1.5l bottles and they were accommodated inside the reactor, so that the total number of bottles was 90, resulting in a surface area of 1.50m2, there was formation of the biofilm In the bottles in a period of time of 90 days, a ratio of residual water 60% with hemodialysis water 40% was used, after the biological treatment the results were: in Chemical oxygen Demand 19mg/l, Biochemical oxygen Demand 14.6mg/l, Total Suspended Solids of 13mg/l, Fats and Oils 1mg/l and Total Coliforms of 3NMP. Complying with the parameters established in the Official Mexican STANDARD NOM-003-ECOL-1997.
