BIOMODULE
Bio Module for Septic Tank Treatment
BioModule is an innovative module for modernizing septic tanks and settling tanks, which transforms a sealed non-drainage tank into a home sewage treatment plant. The set is fully automatic and ensures efficient wastewater treatment, allowing for significant reduction in operating costs. From such a constructed treatment plant, sludge is removed no more than once a year, and the treated wastewater can be used for irrigation of soil and non-edible plants. The product has CE marking, which confirms its high quality and approval for use.

Equipment
- Internal equipment of the tank: pumping station on a support, diffuser with a hose.
- External control cabinet with a control device and a blower (choice of: typical electrical distribution board or low well)
BIOMODULE
Worth knowing
The controller alternates between aeration and settling phases of the activated sludge, fully automatically and with no user supervision.
Activated sludge microorganisms break down the organic and inorganic pollutants in domestic wastewater.
A sludge test is recommended every 6 months, while sludge removal itself is usually needed only once a year or less often.
The pump float, high-level float and current measurement on every controller output detect faults and show them on the display.
When no wastewater enters the plant, the controller automatically reduces equipment operation and returns to normal mode as soon as an inflow is detected.
BioModule is the only CE-marked solution available in Poland for converting an existing watertight tank into a domestic wastewater treatment plant.

"I didn't want to dig up the whole garden for a new treatment plant. BioModule sorted it out. It works in the old tank and simply does its job."
