Reconstruction and intensification of existing WWTPs

Reconstruction and intensification of existing WWTPs

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.

Few weeks of the wastewater treatment plant operation in RAJO - Bratislava dairy

To help our customer with the wastewater treatment plant operation, Hydrotech ensured daily presence of its technologist at the WWTP for a couple of weeks. We operated the plant as it was our own. The main aim was to fine-tune process technology and it´s operation so that effluent limits of treated water were not exceeded. The second part consisted of taking care of the WWTP operational space, to keep it clean and safe. The third point of our action was to optimise chemical dosage into the system. After several weeks of our technologists’ work, we can be proud of this well-functioning WWTP.

Potato processing industry also requires waste water treatment

One of the biggest potatoes-processors in the Czech Republic has decided to invest effort into its wastewater treatment. The key project idea was to treat whole volume of wastewater and its reuse back in the production process. Wastewater coming from potatoes peels and washing include, in addition to organic pollution (COD), also contamination with undissolved substances in grams or tens of grams per litre. The technology consists of mechanical pre-treatment, biological treatment specifically denitrification and nitrification (nitrogen removal), tertiary treatment involving a sand filtration and water sanitation by UV radiation. The sludge dewatering line involves a centrifuge. Wastewater treatment plant is designed as for 426 PE. The hydraulic capacity is designed for approximately 100 m3/day. The treating efficiency is as follows: COD > 95 %, total phosphorus > 90 %, BOD > 99 %, TSS > 99,99 %.

Laboratory tests of highly polluted waste water using chemostat technology

Chemostat is used as a technology for partial treatment of wastewater, for example prior entering a public sewerage or prior next treatment step. In our laboratory we examined food industry wastewater with COD concentration (parameter representing organic pollution) from 2 000 to 4 000 mg/l. Removal efficiency ranged from 45 to 75 % depending on retention time in the system. Nitrogen (N) and phosphorus (P) removal was observed, too. Conforming to local law, wastewater effluent limits from wastewater treatment plants to watercourses usually cannot exceed tens of milligrams per liter. Therefore, chemostat is basically used as a pre-treatment technology.
