Sewage Disposal & Treatment
Sewage Disposal & Treatment
Wilo pumps and systems set new standards in terms of technical performance and efficiency for municipal sewage management. With regard to the protection of the environment and the maintenance of resources, sewage treatment, in particular plays a major role. Experts in the fields of sewage disposal and treatment are under constant pressure to save costs, whilst still meeting the requirements of national regulations and laws. Continuous challenges, such as increasing solid contents in sewage, which hinder operating conditions for systems and devices, require new and innovative solutions to improve the processes and the corresponding products. Selecting the right pumps and systems guarantees reliable sewage disposal: with the highest standards and at the lowest costs.

Pumping station in Tuzla, Turkey.
Reliable sewage disposal.
The Task:
Tuzla Municipal Waste Water Treatment Plant serves a total population of 4.5 million people residing in seven regions of the city of Istanbul. Waste water collected from this area is drawn in via two separate closed channels and then lifted from an elevation of -8.47 m to the treatment plant by two pumping stations.
The Solution:
Three reliable Wilo-EMU FA 50, Ceram coated submersible pumps.
Wilo-EMU FA submersible pumps
Type of construction:
Wilo-EMU FA submersible pumpsSubmersible sewage pump for wet, dry and portable installation
Application:
- Pumping raw water and sewage with solid content in wastewater treatment plants and pumping stations, local drainage, water control and process water extraction
Product features:
- Many different motor and impeller combinations possible
- Self-cooling motors with 1 or 2-chamber sealing system and hermetically sealed cooling system
- NEW: SOLID impeller for maximum process reliability when working with untreated sewage
- Pumps with a macerator or mixer head
- For horizontal and vertical installation
- Simple installation via suspension unit or pump base
- Special materials and coatings against abrasion and corrosion
- ATEX and FM versions
Supervisory association for water supply and sewage removal, Usedom, Germany.
Energy-efficient and reliable in operation.
The Task:
Due to the differing seasonal loads, the sewage quantities vary by more than 40% between the peak and off-peak seasons. This creates a challenge in modernising the sewage disposal system on the holiday island of Usedom.
The Solution:
Optimum drainage solution using Wilo-EMUport pumps stations with solids separation systems and other systems.
Wilo EMUport solids separation system
Type of construction:
Prefabricated pumping stations with Wilo-EMUport solids separation system, for installation in a building, existing sump or integrated into a PE-HD plastic sump
Application:
- De-watering entire localities or large industrial and commercial complexes using conventional gravity-flow drainage systems
Product features:
- High efficiency due to small pump free ball passage
- Uninterrupted operation thanks to double-pump system and individual blocking of solids collection reservoirs
- Environmentally-friendly PE-HD material, corrosion-resistant and recyclable
- Easily accessible, dry-installed pumps and gas-tight collection reservoirs, hygienic and odour-free
Yanqiao wastewater treatment plant, Shanghai, China.
Long lifetime.
The Task:
In the Yanqiao water purification plant, a total of ten Wilo submersible mixers homogenise and suspend the inflowing abrasive water from the Huangpu River.
The Solution:
All the mixers were completely coated with Ceram C0 to protect them from corrosion. Even the PUR propellers received a wear-resistant Ceram C2/C1 coating.
Wilo Ceram
Type of construction:
The unique 2-component coating offers the best possible protection against aggressive media compared with other coatings
Application:
- Effective protection from abrasion and corrosion
Product features:
- Effective corrosion protection
- Increased resistance to abrasion
- Coating can be added later
- Ensures longer lifetimes
