Compare static screens and rotary drum screens for industrial wastewater pretreatment, including flow, solids load, screen opening, energy, cleaning and maintenance.
When an existing RAS reaches its biological treatment limit, this article explains how biofilter capacity can be improved through media selection, oxygen transfer and solids control.
Poor solids removal can overload an RAS biofilter, increase oxygen demand and reduce nitrification stability. Learn how mechanical filtration and biofiltration should work together.
For a space-limited RAS retrofit, HPU sponge media and HDPE MBBR carriers solve different design problems. Compare surface area, mixing, solids control and retrofit requirements.
Learn what flow, tank, solids and hydraulic data should be checked before adding tube settler or lamella media to an existing clarifier.
Learn why fine bubble diffuser pressure rises, oxygen transfer falls and airflow becomes uneven—and what to check before replacing the aeration system.
Compare MBBR and IFAS for wastewater-treatment retrofit projects. Learn how existing activated sludge, clarifiers, aeration, tank volume, ammonia load and media retention affect the choice.
Learn why MBBR media should not be selected by surface area alone. Compare protected area, geometry, density, movement, aeration, retention and biological loading.
Compare 30 μm and 70–75 μm drum filter screens for RAS. Learn how particle size, flow, solids load, backwash frequency and downstream biofiltration affect micron selection.
Learn how pollutant load, SALR, protected surface area, media volume and fill ratio work together in preliminary MBBR sizing—and why tank volume alone is not enough.
