For many years, INTROL has been performing tasks in the field of environmental protection and water and sewage management. We have a long list of recommendations concerning our projects in the field of water and waste water treatment and air/exhaust gas purification systems. We also are a manufacturers of highest class equipment for mechanical waste filtering, mechanical sludge treatment, transport of post-production waste, cement, ash, sand, etc.

We provide services in the scope of:

  • construction and modernisation of water treatment stations and waste water treatment plants
  • comprehensive automation of dams
  • design and construction of water treatment and conditioning systems for industrial and municipal needs (drinking water),
  • design and construction of industrial and municipal waste water treatment systems,
  • design and construction of alternative energy sources: biogas plants, gas engine-based cogeneration system, biomass systems.
  • design and construction of air and industrial gas purification systems for the needs of various industries and power industry,
  • design and construction of odour removal systems for waste water treatment plants, municipal services departments, composting facilities, animal waste processing plants and other plants
  • production of advanced equipment and devices for waste water treatment plants
  • maintenance services for water and sewage plants in Poland
