INCATEMA continues exploiting wastewater treatment in Caracol Industrial Area (Haiti)

On the Biological Diversity World Day, INCATEMA keeps working pursuing sustainable development. The company keeps working on the project we started to build a wastewater treatment plan for Caracol Industrial Area in Haiti, based on the use of macrophyte plants for water treatment.

INCATEMA uses wastewater treatment technology with macrophyte plants that has two advantages. On the one hand, it is a biological cycle where plants, within their own life cycle, absorb some of the polluting elements of the wastewater. On the other hand, the low energy demand of this system makes it easier to make it work in developing countries, being cheaper to operate and capable of being manned by local staff.

One of the clearest advantages is that, taking into account the climate of this country, there are no seasonal biological pauses in plant growth as there would be in other countries with opposed climate seasons.

Technical knowledge on wastewater treatment process

Raw water initially goes through gradually smaller screens that help eliminate solid polluting residues and crosses a fat and oil elimination system for water debit to be divided in two treatment lines of 1,800 cubic m per day each. Each line has seven ponds with different sizes and depths that help eliminate pollutants through aerobic and anaerobic cycles.

Water flows first into the anaerobic pond, then moves to the aerobic pond, going through three clarifying ponds in tandem and finally, water crosses two ponds where phosphorus is removed after flowing through a clay maze supported by a gravel matrix.

Once out of the ponds, water may be treated with ultraviolet rays in case the parameters that make water apt to be dumped are not met. Thanks to macrophyte plants in wastewater treatment, the impact of highly polluted water is better controlled, achieving an optimal riverbed ecological status.
