Upgraded sludge treatment scheme! Qingdao Yimei Environmental Engineering Co., Ltd. complete equipment started to Uruguay Montevideo
Time of issue:
2025-08-04
August 4, 2025-Today, a sludge deep treatment system consisting of screw conveyor, spiral dewatering machine, intelligent dosing tank and internal water microfilter set sail from a Chinese port to help upgrade the municipal sewage treatment plant in Montevideo, capital of Uruguay.
Technical highlights of core equipment
equipment | Technological innovation points | Customer value |
screw conveyer | 304 stainless steel U-shaped groove + shaftless spiral design | Anti-wrapping, conveying efficiency increased by 40%, energy consumption <2.2kW |
Lime dewatering machine | Dynamic ring gap 0.8mm + hydraulic pressure regulating system | The moisture content of clay cake is less than or equal to 80%, and it can be cleaned automatically to prevent blockage |
Intelligent dosing bucket | PE rotomolding integrated molding + metering pump linkage PLC | Resistant to strong acid and alkali, the dosage accuracy error is ±3% |
Internal water inlet microfilter | 316L stainless steel filter screen + internal inlet and outlet mode (precision 50μm) | The interception rate is more than 92%, and the backflow water is saved by 35% |
System integration advantage
▶ Closed-loop treatment of sludge reduction
` Screw conveyor ` Collection of primary sedimentation tank sludge ` Microfiltration machine ` Fine screening ` PAM treatment bucket ` High pressure dewatering to reduce the volume of sludge by 70%
▶ Intelligent control core
-Cloud monitoring of dosage, dehydration pressure and flow parameters
-Automatic SMS alarm for abnormal status (Spanish support)
-Remote diagnosis reduces field maintenance costs by 30%
▶ South American environmental adaptation design
-Equipment bracket carbon steel hot galvanized (resistant to Marine climate corrosion)
-Electrical cabinet IP65 protection class (moisture and dustproof)
-Modular quick installation structure (save 15 days of installation time)
Project background and impact
The municipal sewage treatment plant has a daily capacity of 30,000 tons, and the original sludge disposal cost accounts for 45% of the operating costs. The Chinese intelligent manufacturing solution introduced this time will be implemented through:
1. Energy saving: the total power of the system is less than or equal to 18.5kW
2. Resource recovery: The dehydrated sludge cake can be used as garden substrate soil
3. Land optimization: The equipment group occupies only 80㎡ (60% less than the traditional scheme)
Assist them to achieve the latest Agricultural Sludge Standards of the Ministry of Environment of Uruguay (Resolution 1234/2024)
