METRIA Bio DUO Hybrid 8 Domestic Wastewater Treatment Plant

.

METRIA Bio DUO Hybrid 8 biological domestic wastewater treatment plant with a capacity of 4000L, designed for up to 8 people.

Parameters

The Bio Duo-Hybrid treatment plant is designed for the treatment of domestic and municipal wastewater and can handle any soil and water conditions. It is an ideal alternative to a traditional septic tank for households that cannot be connected to the sewage system.

This is a mechanical-biological wastewater treatment plant. The technology process is based on hybrid wastewater treatment, ensuring a high level of pollutant reduction in compliance with the PN-EN 12566-3:2005 + A2:2013 standard. The METRIA Bio DUO Hybrid 8 domestic wastewater treatment plant also carries CE marking. The tanks are manufactured from high-quality PEHD using the rotomolding method (a plastic forming technique where the mold, divided into two or more parts, is filled with plastic powder or granules, then placed in an oven where the powder melts and, thanks to the rotating mold, forms a monolithic tank).

TREATMENT PLANT DIAGRAM:

1. Chamber No. 1 – Preliminary sedimentation tank

2. Chamber No. 2 – Biological reactor No. 1

3. Chamber No. 3 – Biological reactor No. 2

4. Chamber No. 4 – Secondary sedimentation tank / Clarification chamber

5. Aeration diffusers

6. Treatment plant controller with operational monitoring system

7. Fluidized biological bed

8. Sludge recirculation system with a mammoth pump

9. Membrane blower

The treatment plant features two biologically independent zones. In each zone, low-loaded activated sludge – aerobic bacteria clustered in so-called flocs – forms a suspension actively involved in the wastewater treatment process. This process is further supported by a fluidized biological bed made of specially designed PE elements, on which microorganisms develop and participate in aerobic wastewater purification.

The Bio DUO-Hybrid is a four-chamber treatment plant with two independent aeration zones and a sludge recirculation system, ensuring a high level of pollutant reduction. The combination of low-loaded activated sludge – bacteria clustered in so-called flocs – and a submerged biological bed formed on specially designed PE elements guarantees stable operation of the device. At the bottom of both bioreactors are membrane tube diffusers, through which air is supplied by a blower. The diffuser arrangement and the amount of air supplied ensure optimal mixing and oxygenation of both the wastewater and the biological film, creating excellent process conditions within the reactors.

Advantages of the Bio DUO-Hybrid Treatment Plant:

– The treatment plants are manufactured in accordance with the PN-EN 12566-3:2005+A2:2013 standard and carry CE marking.

– The tank is made of PEHD (polyethylene) resistant to aggressive environments, while its heavily ribbed structure ensures resistance to ground forces.

– Small footprint – all treatment processes occur within the tank, allowing the treated wastewater to be discharged into a ditch, pond, river, or absorbed over a small area using a soakaway pit.

– Very long service life and reliability – simple design of the flow-through wastewater treatment technology.

– Uniform and stable wastewater treatment, resulting in higher pollutant removal efficiency.

– Low electricity consumption – the entire treatment plant uses approximately 0.7 kWh per day.

– Low operating costs – sludge removal required only every 12–24 months.

– Stable operation regardless of the season.

– Fully automated operation.

– 30-year warranty on the tank. 2-year warranty on the equipment.
