Industrial water technologies need to meet increasingly stringent requirements at lower operating costs. The enormous industrial consumption of water calls for flexible and autonomous system that guarantee constant quality at maximum availability and that dispose of the resultant waste water reliably and at low cost.
Tenova Key Technologies offers high-tech solutions for waste water disposal by combining chemical and physical processes:
- Acids
- Lies
- Heavy metals
- Toxic substances
- Oil and fat.

Waste water is treated in customized plants consisting of several processing steps, with low operating costs. The choice of method and sequence will depend on the consumption of the waste water and required degree of purity.
Tenova Key Technologies processes:
- Neutralization
- Chemical treatment
- Precipitation and specific flocculation processes
- Sedimentation
- Mechanical sludge draining
- Preliminary mechanical separation
- Fine separation by membrane
- Sand filter
- Precoat filter
- Ultrafiltration.
The system are designed for continuous or batch operation depending on the volume and concentration rate of waste water. In many cases once the water is purified it can be recovered.
