Water and environmental protection

STAINLESS STEEL AND ITS IMPACT ON THE ENVIRONMENT

Stainless steel has been approved for use in the production of equipment that comes into contact with food and water. The material is completely harmless to humans and the environment. 

The use of stainless steel or aluminum eliminates the need to apply paint and other measures protecting against corrosion, which may be harmful to the environment (emission of harmful substances into the atmosphere during the drying process).

Stainless steel is also used in equipment and installations that help to protect the environment, including sewage treatment plants, in the production of filters, catalysts, etc.

The properties of stainless steel and aluminum, the selection of the right material grade and proper maintenance help to ensure a long life cycle for products made of these materials. This not only allows to save energy and raw materials, but also minimises the amount of waste generated in the production process. A good example is a car silencer. If it is made of stainless steel, it can serve you for the entire lifespan of your car, whereas silencers made of other materials would have to be replaced several times during that period.

Stainless steel can be easily recycled (scrap can be melted and reused), which is profitable, technically proven and implemented in practice. Each stainless steel product can be recycled in about 85%.

WATER DISTRIBUTION SYSTEMS

The most reliable and economical water distribution systems are those that use stainless steel installations.

Steel grades used for that purpose: 1.4301/1.4307, 1.4401/1.4404, 1.4462, 1.4509, 1.4510, 1.4016, 1.4521, 1.4372.

Advantages: competitive price, high resistance to corrosion, malleability.

WASTEWATER TREATMENT PLANTS

The following stainless steel grades are used for the construction of modern wastewater treatment plants: 1.4301/1.4307, 1.4306, 1.4541, 1.4401/1.4404, 1.4571; for special requirements: 1.4435, 1.4462, 1.4439, 1.4547, 1.4529.

The basic requirement that stainless steel intended for contact with wastewater must meet is resistance to corrosion caused by wastewater and products used for its treatment, including mainly chlorides, all oxidising and flocculating agents.
