Mechanical and biological WWTP

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.

Biological cleaning systems that we apply to our WWTP

Low-load selector activation with pre-denitrification

R-D-N processes (regeneration-denitrification-nitrification)

Semi-continuous cleaning systems (SBR)

Biological depletion of nutrients

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.

Wastewater treatment plant intensification in PIKA Bzenec (CZ) factory

A new IC reactor start-up is planned in PIKA Bzenec cannery in August. The factory is increasing production and the hydraulic loading at WWTP is increasing, too. That is why the customer has decided to intensify their plant, which will include extending the existing anaerobic volume with a new same size IC reactor. Part of the intensification will be the installation of more powerful pumps for IC, new biogas treatment ( gasholder with flare for burning excess biogas), increasing of NaOH preparation unit capacity, waste air treatment and new aeration system in the post-aeration tanks. The WWTP capacity will increase from 733 to 1 100 m3/d. Mass loading will change from 5 000 to 7 500 kg/d with 85 % efficiency of COD removal.

Wastewater treatment pilot plant for industrial waste water

For several months, Hydrotech has intensively dealt with pilot plant testing of food industry waste water with high concentrations of organic compounds (COD), sulphur and dissolved inorganic salts. In the first phase, aerobic bacteria were applied so oxygen was needed for them to be able to treat them. After several important adjustments of technology, the process began to work perfectly and the system treats the waste water not exceeding required limits. In the second phase, Hydrotech made a decision to try to treat waste water in anaerobic way. The high loaded IC reactor parameters and treating limits are determined by gradual system loading. Pilot testing results seem very promising, so far.
