## Long description

Sotralentz bioExpert BIO\* Drenaż, 250 g is a biological treatment formulated for drainage-type sewage systems and septic tanks. The product contains selected microbial cultures that accelerate the decomposition of organic matter in drains, soakaway (leach) fields and small wastewater treatment units. It is intended for periodic maintenance of domestic septic systems and drainage beds to support sludge reduction, maintain percolation capacity and help reduce odors and local clogging.
Advantages
The formulation provides active microorganisms tailored to break down fats, proteins and cellulose found in household wastewater, which helps reduce solids accumulation in tanks and soil infiltration areas. Because it is a biological preparation, it works without aggressive chemicals and is compatible with typical septic system processes. The product comes in a 250 g dose suitable for scheduled maintenance and can be applied periodically to keep drainage passages functioning more reliably.
Suitable for
Domestic septic tanks and household sewage systems with drainage-type leach fields
Drainage beds and soakaway systems used for dispersal of treated wastewater
Small on-site wastewater treatment installations requiring periodic biological maintenance
Key specifications
Form: granular biological culture in 250 g package
Primary function: biodegradation of organic matter (fats, proteins, cellulose)
Intended application: periodic maintenance dosing for drainage and septic systems
Compatibility: for use in biological septic and soil infiltration systems (non-chemical maintenance)
Storage: store in a cool, dry place away from direct sunlight
How to use
Apply the product according to the dosing instructions supplied with the package, distributing the granules into the septic tank inlet, inspection chamber or directly into the drainage access point as appropriate. For initial treatment, use the recommended higher dose to establish microbial activity; for ongoing maintenance, apply at regular intervals specified by the manufacturer. After adding the granules, flush with water to carry the culture into the system. Avoid introducing strong disinfectants or high concentrations of chemical cleaners immediately before or after application to preserve microbial viability.
Usage recommendations
Use on a preventive schedule to maintain percolation and reduce sludge buildup; combine with routine septic inspections and mechanical desludging when required. For safety, follow handling instructions, keep out of reach of children and pets, and avoid inhalation of dust when applying.
