Wastewater treatment plant to remove pigments
Commissioning of an industrial wastewater treatment plant to remove pigments, paints and dyes from the water.
Wastewater treatment in the textile industry, where pigments, dyes and paints are made is complex due to the necessary removal of heavy metals present in the water.
For this project, in which a DAF-FPBC50 was installed, the treatment of these complex waters consists in the removal of ammonium by stripping followed by a DAF Dissolved Air Flotation System after adding lime, coagulant and flocculant.
This process results in a significant reduction of heavy metals and fluorides, allowing subsequently purified water to be poured directly into the sea.
The treatment plant treats this wastewater by eliminating the pigments and suspended solids present and thus allowing its subsequent discharge into the sea with full guarantee.
The application of the SIGMADAF System as equipment to remove heavy metals, using whitewash, in turn offers very high performance and facilitates subsequent mud management.
Here we can see the performance of the DAF-FPBC50 and how the suspended solids and pigments have been removed.
The vessel on the left contains a sample of wastewater to be treated and the vessel on the right shows a sample of the water already treated by our DAF.
The water purification equipment DAF-FPBC50 from SIGMADAF has the following particular characteristics:
- Processing of contaminated waters of low or medium load, including those containing particles of low buoyancy
- Compact system
- Unique system of dehydration and sludge disposal, producing large sludge concentrate
- Efficient laminar flow regime
- Low maintenance need and easy to operate
This purification equipment can also be used in the following industrial activities:
- Meat industries
- Textile production
- Processing plants
- Oil industry
The main advantage, among others, of the use of DAF-FPBC50 in the Pigment Industry is the better clarification performance compared to conventional treatments for the removal of water with a high concentration of solids, dyes, fluorides, etc.
