HUBER Chemicals Dosing DIGIT-DOSE Optimal dosing of chemicals even with small mixing and balancing tanks
Chemicals dosing is optimal if the flotation system constantly achieves the required performance without overdosing of chemicals and unnecessarily increasing operating costs. In practice, it proves to be difficult to adjust the chemicals dose due to varying volumes and freights.
Large-dimensioned mixing and balancing tanks are beneficial but can frequently not be installed due to lack of space. Besides, the investments costs are high for the tanks and the accessory equipment required, such as circulation pumps and aeration systems for homogenisation.
The innovative HUBER Chemicals Dosing DIGIT-DOSE allows optimal dosing of the chemicals even with small mixing and balancing tanks.
The specially developed system uses a combination of several measuring principles and constantly determines the optimal chemicals dose in real time.
A cyclically operating cleaning system ensures the constant availability of the installed measuring technology.
Chemicals consumption, and therefore also operating costs, are reduced to a minimum. Additional positive effects can be seen in the volume of flotate sludge generated, a main cost factor of flotation plants for utilisation and disposal.
Furthermore, DIGIT-DOSE makes life easier for the operating staff as the system adjusts automatically to varying wastewater parameters without the need for any manual intervention.
Applications of the HUBER Chemicals Dosing DIGIT-DOSE
- Slaughterhouses and meat processing industry
- Dairies and cheese dairies
- Food companies
- Tanneries
- Animal rendering plants
- General pre-treatment by flotation for highly varying wastewater compositions
- Suitable also for retrofitting existing HUBER HDF installations!
The HUBER Chemicals Dosing DIGIT-DOSE System Benefits
- Up to 30% reduction in chemicals consumption
- Support and relief for operating staff
- Up to 20% reduced flotate sludge volumes
- Production of hydroxide sludge resulting from overdosing of precipitants is effectively avoided
- Integrated automatic cleaning of the measuring equipment used
- Low investments costs and space requirements for mixing and balancing tanks
- Return on investment within few months
Optimized use of chemicals due to the intelligent and permanent dose regulation reduces the amount of flotate sludge. Beside the operating costs for chemicals, disposal costs for flotate sludge are another main cost factor.
The investment costs for the HUBER Chemicals Dosing DIGIT-DOSE pay off for plant operators within a very short time due to the significantly reduced operating costs. Existing plants retrofitted with DIGIT-DOSE have shown that the ROI (Return on Investment) can be achieved within only one year.
If HUBER DIGIT-DOSE is considered and included already in the project engineering phase, the size of mixing and balancing tanks can be reduced to the minimum. Any load variations still present can then reliably be managed with the freight-controlled chemicals dosing solution without any negative effects on operating costs and/or plant efficiency.
