Treatment and recycling system for industrial effluent loaded with MES
Problem / Need :
An industrial customer specialist of cutting stones and other minerals wanted to integrate a water treatment unit to recycle 50 m3/h of process water.
Method used / Answer provided :
To provide an appropriate solution to this problem, the choice fell on the installation of a compact clarifloculation unit, structured in three sections to fit perfectly into the space specified by the customer:
- A coagulation-flocculation module: This unit is specially designed to initiate wastewater treatment by agglomerating fine particles, to facilitate their elimination in the later steps.
- Two lamella decanters: These components play a crucial function in separating the flocs formed during coagulation-flocculation, enabling the process to be used for effective water clarification.
- Connections planned for the future addition of a third lamella clarifier: this technical planning makes it easier to expand the system to support increased production. It ensures the adaptability and scalability of the customer’s water treatment.
Results
Using the clarifloculation process has achieved a reduction in suspended solids ( MES ) of over 98%, and improved the quality of the treated water. This impressive performance has significantly improved the quality of the treated water. However, a particular challenge emerged as a result of the nature of the sludge released. The sludge turned out to be particularly heavy and sticky, which caused problems for the standard pumping process.
