Bolt Standard drainage sewage plant

Bolt Standard drainage treatment plant

The drainage sewage treatment plant is a reliable and long-established type of sewage treatment plant. The Bolt standard domestic sewage treatment plant is used for the treatment of wastewater from residential buildings, from one or more households. The drainage treatment plant consists of a Bolt septic tank, a distribution sump (which regulates the inflow of wastewater to the infiltration system), drainage pipes and aerated ventilation pipes.

Wastewater treatment consists of two main stages. In the first, so-called anaerobic stage, raw sewage flows by gravity into the septic tank. A stage of self-purification of the wastewater takes place. Heavy substances are separated and fall to the bottom of the tank. Fats and oils form a so-called dross. The pre-treated wastewater then flows through the filter to the second treatment stage in the infiltration drain. This stage uses a natural aerobic process, involving the biochemical decomposition of pollutants with the help of bacteria.

Bolt septic tank

The tank is made of linear polyethylene by rotational moulding. It is characterised by its high strength as there are no seams or welds. The septic tank is designed for installation in favourable ground conditions (light, permeable soil). It is resistant to the aggressive sewage environment. The advantage of the septic tank is its low weight, which greatly facilitates transport and installation. Septic tanks placed in the ground do not require thermal insulation. Their operation is possible under various climatic conditions. The settling tank comes with a 5-year warranty for watertightness.

Maximum ground cover up to 40 cm. The installation instructions of the treatment plant must be strictly adhered to These instructions also include location guidelines for the installation of the plant.
