WaterSafe IT Tool
Quick guide
Follow the steps below to use the WaterSafe tool effectively for analyzing and upgrading treated wastewater quality:
Step 1: Enter WWTP and effluent data
Begin by inputting the relevant wastewater treatment plant data. Provide current effluent parameters, including concentrations of key water quality indicators (e.g., BOD5, COD, nutrients), and if possible, more about pathogens, micropollutants, etc.
Step 2: Select the target water quality class
Choose the desired water quality class you aim to achieve. This can be based on intended use (e.g., irrigation, discharge to surface water, industrial reuse) or relevant legal/regulatory frameworks.
Step 3: Automated analysis by WaterSafe
Once data is entered, WaterSafe will automatically compare your effluent parameters against applicable EU legal standards. It will identify whether each parameter is within legal limits, below the required threshold (substandard), or above the permissible limit (potentially harmful).
Step 4: Receive targeted treatment recommendations
For each parameter that exceeds or falls short of the standard WaterSafe suggests the most effective treatment methods (e.g., filtration, disinfection, advanced oxidation). Additionally, the system provides a comprehensive treatment strategy that optimizes simultaneous correction of multiple parameters, efficiency in terms of cost and technical implementation.
Step 5: Review your customized treatment strategy
The result is an optimized, tailor-made wastewater treatment plan, aligned with your selected target water quality class, regulatory compliance requirements, technical feasibility within your WWTP setup.
Tip: Always review the proposed treatment strategy in the context of your local legal environment, operational capacity, and budgetary limitations before implementation.
Result
The tool will indicate the appropriate method of water reclamation for a specific purpose, taking into account technological, environmental and economic aspects. By using the tool, you can significantly contribute to the economic transformation of the water and wastewater sector.
