Industrial WWTP
We regularly implement WWTPs for various industries such as food, pharmaceutical, automotive, paper industry and others.
Sewage WWTP
Our mechanical-biological wastewater treatment plant can be fully adapted to the specific needs of our customer with its technical and technological solutions.
Mechanical equipment for WWTPs
In addition to the complex implementation of WWTP we also supply individual mechanical-technological equipment for wastewater treatment plants and water treatment plants.
Reconstruction and intensification of existing WWTPs
Waste water treatment plants with insufficient efficiency, non-functional parts or small capacity will be modified to keep you fully served.
4 continents, 20 countries, hundreds of wastewater treatment plants
With 40 years of Hydrotech's existence, more than 800 of wastewater treatment plants have been built.
Today they serve communities, cities, towns and industrial enterprises in 20 countries of the world.

Tasty bakery products and wastewater in their production
Wastewater treatment plant for the bakery is in the execution project stage. Capacity of WWTP is the same as for a city with approximately 22,000 inhabitants. Technology used within the plant is divided into 2 sections. The first one is a mechanical part involving rotary sieve, accumulation tank and flotation unit. The main function is to remove bigger particles from wastewater, equalize water quality and remove part of pollution. The second part of the WWTP is a biological stage, where water is treated up to the required parameters with help of activated sludge (microorganisms).
From pilot test to WWTP implementation
A model example of the design and gradual implementation of pre-treatment of industrial wastewater is a project for treatment of wastewater from textile industry. It is a production of textiles used mainly for hot air balloons. Most of the pollution comes from the dyeing line. The beginning of this project consisted of pilot tests of wastewater treatment using flotation, which lasted roughly 2 months. During this period the ability to remove pollution with such technology was demonstrated, so the customer ordered a proven solution.
Wastewater from ammunition production
One of our current customers is interesting because they produce ammunition. No industrial wastewater is produced directly in the production, but some volume is produced by employees and productions located near the factory. The project design involved effective use of existing tanks and transformation of biofilm technology into a conventional system of aerated and mixed tanks with suspended activated sludge.
