The aeration stage and the disinfecting stage are the primary differences from a traditional septic system; in fact, an aerobic treatment system can be used as a secondary treatment for septic tank effluent. [1] These stages increase the initial cost of the aerobic system, and also the maintenance requirements over the passive septic system.
A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...
Secondary treatment domestic vermifilter for wastewater showing ventilation around basket and pine bark media. Secondary and tertiary treatment vermifilters can be underneath the primary vermifilter in a single tower, but are typically single reactors, where several reactors can be chained in series as sequential vermifilters.
During the trial, Sarclisa was administered by intravenous infusion at a dose of 10mg/kg once weekly for four weeks, then every other week for 28-day cycles in combination with standard doses of Pd for the duration of treatment. The primary endpoint of ICARIA-MM was progression-free survival (PFS). Key secondary endpoints included ORR and OS.
“With these results, Libtayo now has the potential to also transform the treatment of high-risk resectable cutaneous squamous cell carcinoma with adjuvant treatment. This trial is a testament to our unrelenting commitment to investigating areas where patient need remains high and to pursuing clinical research across diverse stages of skin ...
