Origin of wastewater

Wastewater originates from different sectors: domestic, communal, municipal or industrial. As a result, the origins of wastewater are multiple. These come from the bathroom, kitchen water, domestic appliances, textile and clothing industries, pulp and paper mills, metal processing industries, etc.

Some facts and statistics

According to data from the Ministry of the Environment, there were 62,000 spills of untreated water in Quebec in 2017 in watercourses. The ministry also indicated that in 2018, 83 Quebec municipalities still did not have a wastewater treatment system. However, the Municipal Wastewater Treatment Facilities Regulation (MWTSR) stipulates that all municipalities must have sewage treatment plants in place by the end of 2020.

In Quebec, municipalities discharge their untreated wastewater into the St. Lawrence River and rivers because sewer systems or water treatment systems are obsolete, insufficient or poorly designed.

Existing methodologies

Wastewater treatment companies use miscellaneous methodologies. For instance, some companies use clean technologies to produce quality products with a good price/quality ratio while limiting environmental impacts. These clean technologies are based on a set of measures applied internally to reduce wastewater pollution. For example, isolating polluted water, reusing water, reusing process solutions, optimizing the use of raw materials and products, etc. In addition, various companies offer miscellaneous solutions for the treatment of municipal and industrial wastewater, etc.

Solugen, an interesting alternative

Solugen proposes solutions for the treatment of highly contaminated water in order to facilitate compliance with environmental standards, social acceptability and profitability of operating activities in the agricultural, industrial and municipal sectors.

Regarding the industrial sector, Solugen’s process makes it possible to transform any wastewater into pure and reusable water.

Steps for the treatment of contaminated water:
– Suitable solid and liquid separation;
– Distillation or azeotropic distillation;
– Recycling water internally.

The Solugen water purification system can recycle up to 97% of polluted water and ensure upstream water quality.
