Deteriorated cleaning efficiency, few dysfunctional parts, or insufficient capacity of your wastewater treatment plant may not be the reason why you need to set up a brand new WWTP. Many existing wastewater treatment plants which can no longer perform at 100% can continue to function without difficulties if you let them refresh or intensify over time.
Our effort is to apply the latest knowledge of science, scientific and technological development in all projects of reconstruction and intensification of existing WWTPs so that all the capacities of an existing WWTP are used as economically as possible. In addition, Hydrotech is able to provide the reconstruction or intensification of existing WWTPs in full operation so you will not have to interrupt or limit production.
We have been testing wastewater containing resistant organic substances and high heavy metals concentrations for several weeks. As these organic compounds are hardly biodegradable, we decided to use advanced oxidation processes (AOP). Based on laboratory tests we chose just Fenton reaction to be used. The drop in initial COD concentrations (parameter for organic substances) in the inflow to the pilot model is approximately 50%. In the second step, heavy metals are removed from the water with an efficiency of about 90%.
In cooperation with our Czech part of the Hydrotech group, we have started to prepare documentation for two smaller food factories with a daily flow rate of about 100 m3/d. Although, the volume of water is relatively small, water pollution is really high. The designed technology is relatively simple with high treatment efficiencies - COD values can be expected to decrease in the range of 40 to 60%, while TSS and fat parameters can achieve efficiency in decrease of up to 90%. Since the pre-treated water continues to the sewer and to the local sewage treatment plant, such efficiencies should be sufficient.
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 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.
