Energy-efficient wastewater treatment saves operating costs
Having expanded its production capacity, Bioresine also needed to expand its existing wastewater treatment plant as a new plant alongside the existing plant.
What we did?
Water is a vital raw material for Bioresine, a Moroccan producer of active pharmaceutical ingredients, orange extracts and essential oils. Having expanded its production capacity, the company also needed to expand its existing wastewater treatment plant as a new plant alongside the existing plant.
Objective
Wastewater from pharmaceutical production needs to be treated energy efficiently in such a way that it reliably meets the requirements of the customer and the authorities. Only limited space was available for the plant expansion.
Around 470 m³ of wastewater needs to be treated for direct discharge every day. The high concentration of organic substances and the high salt content in the wastewater pose special challenges for the plant technology.
Solution
Designed specifically for the customer, the treatment solution begins by separating the solids from the wastewater using a rotary screen. Following neutralisation, the wastewater is fed into a Biomar® aerobic rector, in which the organic components are biodegraded. The bioreactor then separates the biomass from the treated water that can be directly discharged. The plant is equipped with energy-efficient plant components that enable energy savings of around 30%. The automated plant can be monitored remotely using EnviroChemie’s Asic® system, allowing the entire plant to be operated efficiently and reliably – with significant economic and environmental benefits.
Given the high salt content, EnviroChemie uses plant components that are resistant enough for long-term use.
Benefits
The new plant solution enables Bioresine to reliably comply with the specifications for direct discharge into the river and to save operating costs. The dewatered sludge can be used as fertiliser in farming operations.
