In the process of industrial development in Mozambique, "meeting environmental standards" and "water scarcity" have consistently been dual challenges faced by local enterprises. Glopol, a local company focusing on environmental protection and valuing green and sustainable development, has adopted a highly efficient wastewater treatment system tailored and built by BoReTech for its PET bottle recycling and washing project. This system not only solves the difficult issue of wastewater discharge from waste plastic recycling and washing but also achieves water resource circulation, injecting new impetus into the local industry's green development.


  • This wastewater system has a treatment capacity of 20 m³/h, with stable effluent water quality that exceeds industry standards.

  • Specifically, Chemical Oxygen Demand (COD) is controlled below 500 mg/L, Biological Oxygen Demand (BOD) does not exceed 200 mg/L, and Suspended Solids (SS) are less than 5 mg/L, significantly enhancing water clarity.


  • The treated wastewater realizes "cascade utilization," with approximately 50% recycled back into BoReTech's PET bottle recycling and washing production line, and the remaining portion discharged after testing confirms compliance.

  • The treated sludge has a moisture content of no more than 80%.

From the perspective of emission reduction effectiveness, this system can annually reduce the discharge of 540 tons of COD, 250 tons of BOD, and 360 tons of suspended solids into water bodies. When converted into water body purification capacity, this is equivalent to preserving the cleanliness of several large local lakes, significantly reducing the burden of industrial production on the surrounding water environment, resulting in notable ecological benefits.


On the technical level, the system employs BoReTech's core E4-Aps-B20 process, achieving efficient decontamination through a combination of "Coagulation Sedimentation + Flotation." During the treatment process:

  1. Poly-Aluminum Chloride (PAC) is first added to aggregate the impurities in the water.
  2. Polyacrylamide (PAM) is then added to accelerate sedimentation.
  3. Heavier solid particles are separated through sedimentation.
  4. Lighter oil impurities attach to micro-bubbles and float to the surface. This ultimately achieves the deep removal of suspended solids, oils, and organic pollutants.

The successful implementation of the Glopol project in Mozambique is another validation of BoReTech's engineering service capability and the reliability of its supporting wastewater technology. Furthermore, it provides a replicable and scalable "wastewater into resource" model for industrial enterprises in the African region, aiding the global industrial green transformation.
