The wastewater generated in industrial companies comes from different production processes, with partly strongly varying flow volumes and loads. To ensure continuous feeding of the flotation plant nevertheless, a mixing and balancing tank for homogenisation is installed upstream of the flotation plant. Varying loads can be reduced this way but not prevented completely.
Varying loads cause increased operating costs
To ensure in daily practice that the required clarification efficiency is achieved even with peak loads, precipitants and flocculants are overdosed.
Another possibility is the manual adjustment of the doses by the operating staff. This reduces chemicals consumption but requires personnel.
Intelligent freight-dependent dose control minimizes operating costs
HUBER has risen to this challenge: with a flotation plant that both achieves the required clarification results reliably and at any time despite varying inlet loads and at the same time minimizes the consumption of precipitants and flocculants without staff attendance!
This challenging task has been met with the newly developed DIGIT-DOSE system.
The intelligent dose regulation is at the heart of the DIGIT-DOSE system, permanently determining from the measurement data of different sensors the pollution degree of the wastewater and adding then the required dose of different chemicals.
Such optimized use of chemicals reduces also the amount of flotate sludge. Beside the operating costs for chemicals, disposal costs for flotate sludge are another main cost factor.
DIGIT-DOSE meets expectations in practical operation
The feedback received from plant operators to date are very positive and confirm that DIGT-DOSE has fully reached the development targets:
