In the absence of a treatment plant, the wastewater is stored before being removed for disposal by an external service provider. The disposal and reprocessing costs are expensive. In addition, there are the constraints and risks of storing the wastewater on site. Our customer decided to call upon NISKAE for a solution of treatment and discharge to the sewer for its glue machine rinsing water.
A company specializing in the fitting out of professional commercial vehicles uses a gluing machine. In order to ensure its maintenance, the glueing machine used requires rinsing and cleaning with water daily or after each use. This cleaning generates a volume of wastewater of approximately 150 to 200 liters per day.
Disposal and reprocessing costs have become expensive
Several results have been conclusive following the addition of a customized coagulant-flocculant
First, a preliminary wastewater study was performed in the laboratory on a sample taken on site and representative of the rinsing water generated by their glue machine rinsing process. Analyses and tests were carried out in order to obtain the best coagulant-flocculant reagent.
The analysis of this water revealed a concentration of iron (0.90 mg/L) and zinc (2.25 mg/L). After several laboratory tests, a powdery product was determined with a dosage of 3 g/L. The latter allowed a significant reduction of the heavy metal concentration while neutralizing the pH, with an average value of 7.30. Indeed, the coagulant-flocculant complex allowed to reduce the concentration of heavy metals, such as iron reduced to 0.02 mg/L and zinc reduced to 0.01 mg/L.
The NISKAE team recommends a treatment plant that allows direct discharge to the sewer
After the preliminary analysis and the tests carried out, considering the volume and type of the effluent of our Client, NISKAE proposes the installation of a semi-automatic water treatment plant type SW100, so that the water can be discharged to the sewer. This microstation proceeds by batch treatment of 100L. The wastewater is first collected in a 250L collection tank located under the gluing machine. The wastewater is then transferred to the SW100 treatment reactor where the separation reaction and flocculation take place with the addition of the coagulant mono-reagent developed by NISKAE
Our client benefits from an ROI of less than 12 months by implementing the NISKAE solution
By calling upon NISKAE, our Client can now treat and discharge its wash water to the sewer in full compliance. By opting for the NISKAE solution, our Client benefits from the reduction of treatment costs, a discharge of its treated water directly into the sewer and a return on investment of less than 12 months, all while having a positive impact on the environment.
