Sommaire du projet

Cosmetic wastewaters are characterized by relatively high concentrations of organic and inorganic compounds, suspended solids, oil and grease, emulsions, heavy metals, and active substances such as moisturizers, fragrances, surfactants, antiseptics, dyes, vitamins, and UV filters. The challenge for treatment of these wastewaters is the large fluctuations in their compositions and concentrations, resulting from various products containing different ingredients being produced throughout the day. Depending on the composition of the products being produced, wastewater generated may foam excessively at times. The presence of active substances, a non-readily biodegradable contaminant, is the main source of concern in treating cosmetic wastewaters. As cosmetic products can produce wastewaters with concentrations in excess of municipal standards, personal care product producers must either treat wastewater onsite or pay high fees for discharge into municipal sewers. Due to the large costs associated with municipal discharge, onsite treatment technologies with low capital and maintenance costs are the most desired option for producers. In collaboration with Fleming College's Centre for Alternative Wastewater Treatment, this applied research study will identify opportunities for reduction and optimization of water specific to the treatment of cosmetic wastewater. This research will be conducted at a Personal Care Manufacturer's facility in Ontario where a best available technology for treatment will be selected and installed. It is anticipated that results from this research will lead to sustainable operations within the existing facility, and improved reduction of organic matter, suspended solids, and heavy metals. In addition, this research will enhance our knowledge of these problematic wastewaters and their treatment solutions.
