Industrial and sewage / Biofuels
We provide our clients with mechanical and biological waste water treatment plants within a wide range of capacities that can be fully adapted to their requirements. Depending on the size and location of the WWTP, we offer sewage treatment in concrete, steel and plastic tanks as well as compact (container) WWTPs.
The advantages of our WWTPs are, above all, minimal space requirements, appropriate integration into the existing environment, as well as the possibility to choose between a covered and an underground object. Do not worry about unwanted smell, harmful emissions or noise.
Every brewery needs malt from a malt house at the beginning of its production process. For such a food industry, we finished wastewater treatment pilot plant this month. We are extremely satisfied with the results as we managed to lower the organic pollution to 50 mg of COD/l and 5 mg of BOD/l. It is really interesting for the customer to use significant part of the treated water back in the production process, thus approaching the so-called zero liquid discharge factory concept. That is why it will be necessary to treat the effluent using advanced oxidation processes or by reverse osmosis in the tertiary stage.
Hydrotech has again confirmed its qualities in Russia where we succeeded in being awarded a project which includes execution of the WWTP for a company producing syrups. Wastewater flow is not significantly high (approximately 120 m3/d), but the concentrations reach up to 6 000 mg of COD/l. In the first stage, relatively simple biological aerobic treatment will be performed. If the factory production will be increased in the future, the design of the second stage is already prepared as a biological anaerobic wastewater pre-treatment and the effluent will be post-treated in the aerobic stage.
Our employees came back to Slovakia at the beginning of the December who had finished part of their works in North Dakota, USA. They completed works regarding the wastewater treatment plant especially the high-loaded IC reactor during their stay. In addition, they removed remaining, unused material from the reactor bottom area to be able to seal the reactor´s top. One of the latest tasks was the completion of the odor removal system from wastewater treatment plant´s tanks. At the end of their visit, the pipeline for pH adjustment was installed and pressure tests were carried out.
Hydrotech specialists guarantee high quality solutions to all kinds of clients across several industries.
Starting with design through construction to completition we have been able to deliver more than 700 wastewater treatment plants across Europe, Asia, Africa and Caribbean.
