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)
