Wastewater treatment plants

KRÁLOVOPOLSKÁ RIA has been delivering the wastewater treatment plants to both Czech and foreign customers since 1957. The trade activities in the environmental area are focused on the constructions of municipal and industrial wastewater treatment plants.

The wastewater treatment plants are delivered with the technology of the treatment which complies with all quality requirements for wastewater discharged to surface water in compliance with Czech and EU legislation.

KRÁLOVOPOLSKÁ RIA delivers both the „turn-key“ municipal plants and the technological parts of the plants over 500 P.E. capacity. Chemical and biological treatment technology is used in the industrial wastewater treatment plants depending on the water pollution.

Municipal wastewater treatment plants

500 - 5 000 P.E. wastewater treatment plants

The biological part of the WWTP plant uses the different biological treatment processes with the aerobic sludge stabilization. The biological activated sludge processes are used in the different arrangements (i.e. biological processes with simultaneous nitrification/denitrification, pre-denitrification with nitrification, SBR - type).

The organic pollution and the content of nitrogen and phosphor in outlet WWTP are reduced. KRÁLOVOPOLSKÁ RIA offers the wastewater treatment plants of the type series with the RIA 500 - 5 000 RD/N and RSDN identification.

5 000 - 50 000 P.E. wastewater treatment plants

The biological part of the wastewater treatment plant uses the modified biological activated sludge systems with the aerobic sludge stabilisation. The organic pollution and the content of nitrogen and phosphor in outlet WWTP are reduced by a biological method; and if necessary the chemical coagulation processes are applied to eliminate phosphor. The biological processes are used in the different arrangements (i.e. circulating activated sludge systems of treatment, pre-denitrification with nitrification, variants with selectors eventually separated sludge regeneration).

Wastewater treatment plants over 50 000 P.E.

The proposed technology corresponds to local conditions and waste water quality. The wastewater treatment plant consists of rough pre-treatment and mechanical pre- treatment with primary sedimentation, biological part with activated sludge systems of treatment, sludge and gas management, sludge processing and disposal. The additional water purification uses water filtration in the outlet WWTP, eventually a water sanitation is applied.


Industrial wastewater treatment plants

The treatment plants of the wastewater from the machine-engineering, chemical, food industry and waste water from the agricultural production are treated by the special procedures in compliance with the nature of the pollution.

Outlet from plating plants and metal refining plants

Acid, alkaline water, high salt content water or highly toxic wastewater are disposed by neutralisation, by chemical procedures with final salinity conditioning.

Outlet from steel works and iron works

Residual pollution of the pre-treated ammoniac water from the coking plants, as well as from pickling water in the rolling mills and from outlets containing cyanides are eliminated by neutralization and the biological method.

Chemical and pharmaceutical wastewater

The treatment plants use the pre-treatment process and aerobic or the anaerobic biological processes of the treatment. The technological tests in the pilot plants are usually necessary.

Waste water from refineries and petrochemical plants

Oil separation by the gravity method is performed in two steps. Disposal of emulsified oils is carried out by chemical or physical methods. High-loaded biological water treatment technology is applied as a final stage in this treatment process.

Waste water from food industry and agricultural production

Organic polluted water is treated in high-loaded anaerobic UASB type reactors. The anaerobic stage is completed additional aerobic purification. Less polluted wastewater is treated by the sequencing system in an SBR reactors. Wastewater from livestock farms and slaughterhouses are treated depending on the nature of pollution by a combination of anaerobic and aerobic treatment technologies, produced sludge is composted.
