Textile and Leather Industry
Wastewater and sludge treatment for the production and processing of textiles and leather
- Save disposal costs
- Clean wastewater
- Minimise residues
- Separate solids
- Reduce operating costs
- Recover wastewater heat
- Save primary energy
Wastewater from textile and leather industries contains high loads of solids, particularly fibres and hair. Washing the raw materials also causes a lot of grit to get into the wastewater. The wastewater is usually highly discoloured and contains high BOD and COD loads, so heavy pollution charges have to be paid. It is therefore economical to reduce these loads on site to such a degree that the wastewater can be discharged to the public sewer system or even directly into a water course without having to pay fees for heavy pollution.
While small plants only have to separate solids, larger facilities also reduce the COD and BOD loads.
Due to the large water consumption, it is often economical to treat the wastewater so well that it can be recirculated as process water.
HUBER products and solutions for your requirements
HUBER Complete Plant ROTAMAT® Ro5 units are used for mechanical pre-treatment of process water or wastewater. This type of plant screens out larger solids and separates settleable materials such as grit in the integrated grit chamber. The separated grit can be cleaned from organic contaminants in a downstream HUBER Grit Washer.
The pre-cleaned water can then be further treated with a HUBER Fine Screen to remove fine fibres and hair.
A chemical-physical treatment stage with the HUBER Dissolved Air Flotation Plant HDF further increases cleaning performance. Solids and grease are largely separated as flotate sludge. BOD and COD concentrations are thus significantly reduced, so that the effluent can be discharged into the public sewer system.
HUBER Thickeners and HUBER Screw Presses are available for thickening and dewatering of flotate sludge and excess sludge.
With the HUBER Heat Exchanger RoWin, the often very high wastewater temperatures can be reduced and the heat thus recovered can be used for preheating process water or heating buildings.
