How BIOROTOR works?

The BIOROTOR is a Rotating Biological Contactor (RBC) system. Rotating Biological Contactor (RBC) is a type of secondary wastewater treatment which consists of a series of closely spaced, parallel discs mounted on a rotating shaft, placed just above the surface of the wastewater. Microorganisms grow on the surface of the discs which enables degradation of wastewater pollutants and improves water quality.

This completely modular system can incorporate all processes, including primary settlement, anaerobic digestion, anoxic and aerobic treatment, final settlement, and polishing and disinfection in a single arrangement.

The BIOROTOR automatically adapts to organic load and hydraulic variations.

STEP 1 : Wastewater Is Collected And Enters the Primary Settlement Zone (Anaerobic)

The wastewater enters the primary tank in which the solids and liquids separate. As sludge settles at the
bottom, scum forms on the surface, then the pre-treated water flows into the BIOROTOR.

STEP 2 : Liquid Enters the BIOROTOR (Aerobic treatment)

In the BIOROTOR (Aerobic zone) the wastewater is exposed to a series of discs on which a matrix of
microorganisms grow. The bacteria then consume the nutrients in the water. The discs rotation creates a gentle flow path, moving wastewater along the zone while sloughing ageing surplus biomass from the
discs. This enables space for new biofilm development.

Should nutrient reduction (denitrification) be required, anoxic conditions can be created in the primary settler by recirculation of the mixed liquor from the aerobic zone through the first stage of primary settlement.

STEP 3 : Final Settlement Zone

The treated effluent flows into a lamella clarifier, where accumulated sludge in the bottom of the unit is

periodically removed with a pump. The swimming sludge is also frequently removed through an automatic valve.

STEP 4 : Optional Disinfection

In order to use the final treated effluent for irrigation purposes, it needs to pass through a final disinfection system unit such as a ultraviolet disinfection system or chlorinator.
