Boretech: Over 1,000 Tonnes of Annual Emission Reduction + Reclaimed Water Reuse! Helping Glopol in Mozambique Turn "Wastewater into Resource"

In the process of industrial development in Mozambique, "meeting environmental standards" and "water scarcity" have always been dual challenges for local enterprises. Glopol, a local enterprise, prioritizes environmental protection and values the green and sustainable development of the company. For its PET bottle recycling and cleaning project, Glopol has installed a high-efficiency wastewater treatment system custom-designed and built by Boretech. This system not only solves the problem of wastewater discharge from waste plastic recycling and cleaning but also realizes water resource recycling, injecting new impetus into the green development of local industries.

The wastewater treatment system has a processing capacity of 20 m³/h, with stable effluent quality that exceeds industry standards. Specifically, the Chemical Oxygen Demand (COD) is controlled below 500 mg/L, the Biochemical Oxygen Demand (BOD) does not exceed 200 mg/L, and the Suspended Solids (SS) are below 5 mg/L, significantly improving water cleanliness. The treated wastewater is "utilized in a gradient manner": approximately 50% is reused in Boretech’s PET bottle recycling and cleaning production line, while the remaining part is discharged after passing compliance testing. The moisture content of the treated sludge does not exceed 80%.

In terms of emission reduction effects, the system can reduce the discharge of 540 tonnes of COD, 250 tonnes of BOD, and 360 tonnes of suspended solids into water bodies annually. Converted based on water purification capacity, this is equivalent to protecting the cleanliness of several large lakes locally, greatly reducing the load of industrial production on the surrounding water environment, and achieving remarkable ecological benefits.

Technically, the system adopts Boretech’s core E4-Aps-B20 process, which efficiently removes pollutants through a combined method of "coagulation-sedimentation + flotation". During the treatment process, polyaluminum chloride (PAC) is first added to clump impurities in the water, followed by polyacrylamide (PAM) to accelerate sedimentation. Solid particles with higher specific gravity are separated by sedimentation, while lighter oil impurities adhere to microbubbles and float to the water surface. Ultimately, this achieves deep removal of suspended solids, oil, and organic pollutants.
