DESCRIPTION AND CHARACTERISTICS OF A BIOLOGICAL PROCESS

  • The system MBR replace the process of sedimentation, filtration and disinfection, and suspended solids removing them with one membrane of ultrafiltration.
  • The only chemicals used are in the process for conservation and cleaning of the membrane and It is sodium hypochlorite disolted 20 times form a commercial solution of 15 %.
  • The ultrafiltration membranes let to work with one level of solids between 10 and 15 grams per liter.
  • The MBR system produce an effluent quality constant regardless of the input flow, work with levels (type batch).
  • It provides a vey effective treatment for high valve according with the regulations of title 22 California, the valve are:

 

DBO 5 < 10 mg/l
SS     < 5 mg/l

 

  • It’s a biological system with total oxidation stages of nitrification and desnitrification.
  • Comparing with conventional biological system comprising pretreatment biological treatments, sedimentation, filtration and sterilization, on this system only we use a pretreatment and a biological reactor with membranes.
  • Allows the separation solid-liquid through ultrafiltration membranes of 0,05 microns.
  • The systems of the aeration and the oxygen consumption is the same comparing with conventional system.
  • The membranes retain all kind of bacteria, funghis viruses, parasites and further to clarify the water until 99,99 %.
  • Don’t produce problems of bulking in the absence of the sedimentation.
  • The sludge age is far that one conventional system, allowing to obtain treated water in a good quality which can be reused.
  • The cleaning of the membranes is automatic using coarse bubble air injected, in the button of the membrane or including chemicals for cleaning the membrane.
  • Minimum work pressure is required on the suction.
