Ceramic glaze wastewater represents a challenge in industrial treatment. Its complexity goes beyond conventional water, micronized frits, heavy metals (Zn, Pb, B) and specialized additives that require advanced engineering solutions.
Unlike water generated in processes such as slip preparation or general cleaning, glazing effluents contain micronized frit suspensions, heavy metal oxides and organic and inorganic additives that make clarification and stabilization difficult. This type of water requires wastewater treatment plants (WWTPIs) specifically designed with advanced chemical engineering and process control criteria. In short, the treatment of ceramic glaze water requires a specialized solution.
Ceramic glaze water treatment. Specialized design with focus on physical-chemical stability.
At Grins Environmental Engineering, we approach the treatment of these waters from a process-oriented perspective and the reaction kinetics of the contaminants present. Our systems include: solutions for the efficient treatment of ceramic glaze water.
- Coagulation-flocculation reactors with automatic control of pH, ORP and hydraulic retention time, ensuring the breakdown of resistant colloidal structures.
- Controlled reagent dosing by means of adaptive algorithms, calibrated from Jar-Tests under simulated operating conditions.
- Trace metal separation modules using ion exchange resins or specific adsorbent media, applicable in production lines with more demanding discharge restrictions.
- Homogenization and equalization systems to reduce the dispersion of parameters before the main treatment stage.
Advanced monitoring and operational traceability
Given the high variability of input parameters, it is necessary to implement a robust analytical control system to ensure the correct treatment of your ceramic glaze waters:
- On-line monitoring of pH, conductivity, redox potential (ORP), COD, suspended solids (TSS) and turbidity.
- Control of heavy metals by ICP spectrometry or specific photometry in routine analysis.
- Periodic sampling and Jar-Test programs, with seasonal updating of the chemical treatment protocol.
- Digitized records for traceability and multivariate analysis of operational deviations.
Technical impact on plant operation
A WWTPI designed specifically for glaze water not only ensures regulatory compliance, but also generates tangible competitive advantages: effectively managing the treatment of ceramic glaze water provides several benefits.
- Significant reduction in the volume of sludge generated and improvement in its rheological stability.
- Increased metal collection efficiency and reduced environmental risk.
- Optimization of reagent consumption, avoiding overdosing and losses due to chemical incompatibilities.
- Prevention of fouling in pumps, valves and pipelines by reducing metal oxides in recirculation.
