Effective odour elimination through targeted hydrogen sulphide binding
Long dwell times of wastewater in the sewer network lead to the formation of hydrogen sulphide (H2S) due to a lack of oxygen. This causes unpleasant odours and can corrode pipes and structures. Precise dosing of suitable reagents prevents the formation of H2S and reduces existing loads in the sewer network.
Challenges in the sewer network
- Anaerobic conditions promote the formation of hydrogen sulphide.
- Odour nuisance for local residents due to H2S outbreaks in the event of heat and low flow velocities.
- Corrosion of concrete, stainless steel and fittings due to oxidation to sulphuric acid.
- Rising operating and maintenance costs due to damage to buildings and systems.
- Safety risks for personnel due to toxic H2S concentrationsin shafts.
The solution from sera
- Prevention of hydrogen sulphide formation: Precise dosing of iron(II/III) salts, nitrate solutions or oxidising agents to bind or convert H2S.
- Targeted and economical addition of chemicals: Dosing of divalent metal salts such as iron(II) chloride (FeCl2) for effective reduction of H2S loads.
- Safe system concept: Installation in insulated outdoor cabinets or hazardous substance containers for the storage of water-polluting substances in accordance with regulations.
- High storage capacity: Designed for one IBC or up to 9 × 200 litre drums for continuous operation.
- Stable operating conditions: Lockable design with on-demand heating for safe operation even at low temperatures.
- Robust design: Pallet truck-accessible gratings (up to 2,000 kg/m² load capacity) and building authority-approved drip tray for safe storage.
- Quick commissioning: Plug & Dose principle enables simple installation and a quick start of the system.
The precise dosing technology from sera guarantees reliable elimination of hydrogen sulphide, protects sewer networks from corrosion and ensures lasting odour-free operation - efficient, safe and practical.
