Plant In Peru Treats Agro-industrial Waste

Camposol, an agro-industrial company based in Peru, has implemented a new biological system for treating effluent generated during its growing and processing activities

The system uses specially grown aquatic plants which “eat” the organic matter suspended in the water. This allows the company to regulate water quality parameters such as acidity, temperature, biochemical oxygen demand, chemical oxygen demand and turbidity.

According to Camposol, its new approach also creates a fauna ecosystem, attracting insects, toads and birds.

Camposol’s environmental coordinator, Jhon PÈrez Fern·ndez, said that as well as improving water quality the new system reduces odors and improves the scenic landscape. It also significantly reduces power consumption and the need for chemicals to treat the wastewater, as the plants work as natural filters and are resistant to temperature change.

The wastewater treatment plant has five wells, which are covered with a geo-membrane.

Treated wastewater is subsequently reused for irrigating green areas around the wastewater treatment plant. This improves the landscape of a conventional wastewater treatment plant to a green and environmentally friendly one, Camposol said.

Camposol is the the largest avocado grower and one of the biggest producers of blueberries in the world. Its operations include the harvest, processing and marketing of foods such as asparagus, grapes, mangoes, peppers, artichokes, tangerines and shrimps, as well as avocados and blueberries.

The company exports its products to the United States, Europe and Asia.
