Municipal wastewater operations
lipasanF® supports microbial fat splitting at hotspots such as inlets, grease shafts and pumping stations. This can help reduce deposits and scum layers – and therefore the conditions under which hydrogen sulfide (H₂S) forms.
Quick overview
The focus is prevention and routine instead of reactive call-outs:
Note: results depend on site conditions (hydraulics, temperature, load profile). We recommend a monitored pilot.
Focus on hotspots
Inlets, pumping stations and grease shafts are typical areas where fats accumulate and H₂S can form.
No performance promises: dosing points/intervals/amounts are defined per site.
Fats and organic deposits build layers (e.g., scum). Beneath them, anaerobic conditions can form – a driver for sulfate reduction and H₂S. This leads to odour, corrosion and high operational effort.
Many measures are symptomatic (flushing/mechanics). Prevention starts earlier: at the fat/deposit base and at hotspots.
lipasanF® supports microbial fat splitting. The goal is to destabilize fat deposits and convert them into biologically usable intermediates – before stable layers and anaerobic zones dominate.
At hotspots, regular dosing can help reduce fat deposits and scum layers – and thus conditions that promote H₂S formation.
Site-specific instead of generic recipes: dosing points, amounts and intervals are defined based on real conditions.
Preferably dose during low-flow periods to use contact time.
The goal is not “magic”, but reducing hotspot stress and stabilizing maintenance routines.
Note: outcomes depend on load profile, temperature, hydraulics and geometry. We recommend site-specific design and monitoring.
Preventive routines can shift reactive costs (vacuum trucks, removals, failures) into more predictable budgets. References mainly highlight day-to-day relief: less manual work, less disposal, less stress at hotspots.
When fat deposits and scum layers decrease, removals become less frequent and workflows become calmer.
H₂S is not just an odour issue – it is also about safety and materials. Prevention can reduce risks.
For solid ROI numbers, run a monitored pilot and document intervals, complaints, alarms and (if available) H₂S measurements.
Many measures start only when the hotspot is already blocked. Preventive dosing starts earlier.
| Criterion | Mechanics/flush | Chemicals | lipasanF® |
|---|---|---|---|
| Principle | symptomatic | symptomatic | root-cause & routinable |
| Cost structure | high per intervention | ongoing / material-critical | predictable (routine/pilot) |
| Materials/environment | neutral/mechanical | potentially aggressive | biological & material-friendly |
| Long-term value | limited without root cause | limited without root cause | high with proper design |
The best approach is often a mix: preventive routines + targeted mechanical actions when needed.
Most systems have recurring hotspots. Prevention pays off exactly there.
Inlet & grease shaft
Stable fat layers often form in shafts. Routine dosing can destabilize deposits and simplify maintenance.
Note: dosing and intervals are defined per site.
Pumps & sewer network
Scum and fat films can promote anaerobic zones. Prevention can reduce odour and corrosion pressure.
Note: dosing and intervals are defined per site.
CSO/overflow & site area
During stagnation or fluctuations, odour peaks occur. Hotspot dosing can reduce the risk.
Note: dosing and intervals are defined per site.
We help assess the situation, select dosing points and define a pilot setup including monitoring checkpoints.

What you see in the video
We identify hotspots and operating conditions and derive a suitable pilot phase and dosing logic — aligned with infrastructure, load, and operating times.
Fast start, clear routine: define dosing point, use contact time, adjust interval to the load profile.
Dosing point
We dose where fats and deposits actually form: shafts, inlets, pumping stations or defined sewer sections.
Application
Application is simple – dilution, timing and consistency matter.
We provide a site-specific SOP/instruction.
Operation
Handling is straightforward; design is site-specific.
We review hotspots, propose dosing points and define a pilot setup – including a monitoring checklist.
Note: amounts, intervals and SOP are defined per site.
Short and practical: what operators typically ask.
If you have data (H₂S, complaints, removal intervals), it helps evaluate the pilot.
We review your situation, estimate dosing needs & savings potential, and guide the pilot phase — transparent and measurable.
