Treatment Using Aerobic Processes TRIZ Cases

Controlled microbial dosing maintains a youthful population to produce pathogen-free Class A sludge without harsh chemical disinfection.

A floating fluid circulator generates non-linear radial flow to mix oxygen with waste treatment water.

HDPE fiber fabric enables simultaneous nitrification and denitrification by supporting diverse microbial colonies in aerobic and anoxic zones.

A sewage treatment system supplies oxygen to dehydrated sludge for aerobic fermentation, producing microbial spores that activate in the flow.

Angled baffle portions redirect water flow to expand settling chamber volume, reducing suspended solid counts without increasing plant footprint.

Vaporized acid cleans fouled aeration diffusers by dissolving mineral scale and killing bacteria, restoring pressure and efficiency.

A continuous algae water treatment system blends dense microalgae culture with conditioned influent for nutrient uptake in an enclosed photobioreactor.

Oxygen enrichment membranes reduce gas dissolution energy and chemical oxidant demand in wastewater separation.

A wastewater treatment system combines aerobic, anoxic, and anaerobic zones within two interlinked tanks to enable biological contaminant removal.

A mainstream deammonification process bypasses primary effluent into an IFAS reactor during air-off periods to maintain nitrite availability.

A pneumatic aeration apparatus uses a plenum to direct air flow into lift tubes, creating a counter-clockwise swirl in wastewater.

Sealed draft tubes prevent clogging while generating shockwaves that mix wastewater without high-pressure compressors.

Alkaline pH adjustment precipitates phosphorus in acidic pulping effluent, reducing removal costs compared to tertiary treatment.

A filter system recirculates water through a treatment chamber via a valve arrangement to maintain biological filtration.

Porous concrete ventilated mats distribute vehicular loads while maintaining gas flow through underlying water infiltration fields.

A microbial consortium degrades hydrocarbons through complete mineralization.

Removing the bottom wall from a stormwater treatment container allows roots to grow freely and treated water to infiltrate groundwater.

A floating media filter uses a diffuser trough to separate effluent from the expansion zone.

Vertically oriented leaching modules redistribute effluent via balancing pipes, preventing localized saturation and extending system lifespan.

Dissolved air flotation extracts suspended solids and BOD prior to biological treatment, reducing system volume and sludge production.

A modified aerobic biological reactor treats sewage through integrated flotation and decanting mechanisms.

Large mixing bubbles generate currents that reduce power consumption while maintaining anoxic conditions in IFAS systems.

Vertical partition walls in a single tank create rotational horizontal circulation, reducing sludge production and operational costs.

Integrating photoactive semiconductors with bioelectrochemical reactors boosts degradation rates while eliminating sludge generation.
