Biological treatment plants

Biological treatment plants provide guaranteed reliability for decades

Uponor's biological-chemical treatment plants are high-quality, efficient and modern wastewater solutions. The range of water treatment plants covers single-family homes to village-scale systems. Biological treatment plants consist of septic and process tanks, where the purification process takes place. The water treatment plant is operated automatically using logical functions. Purified water can be led into a ditch, into the ground for absorption or for ground filtration.

Uponor biological treatment plants are built at the factory and delivered ready for installation and use. They are quick to install and easy to site, even on small plots. They do not require any special soil characteristics, and they are suitable for use on new-build sites as well as in renovated buildings.

2-6 household

Uponor Infra has three different smaller types of approved mini treatment plants: Clean, Wehomini and Wehoputs. The choice is yours!

Uponor mini treatment plant Clean

Clean is a biological/chemical treatment plant, which can receive the household wastewater from up to 2-6 properties. The function is based on batch cleaning technique, active sludge process and chemical precipitation of phosphorus. The wastewater is purified in batches of the same size thus cleaning all sewage rates as efficiently. The biological purification process is carried out by microorganisms that live in the active sludge. With the help of flocculants phosphorus in the wastewater is purified. When the purification process is completed, the purified water is pumped to the intended outlet. The mini treatment plant Clean works both in continuous operation and on summer cottages due to the automatic automation system.

WehoPuts mini treatment plant – a good choice for the environment

WehoPuts is intended for sewage treatment. The plant is designed for the treatment of wastewater for up to 2-6 households. The mini treatment plant is easy to transport and install due to the compact size and space needed. The delivery includes a complete anchorage package, which facilitates a quick assembly. The treatment plant is equipped with a stable lockable lid. The lid looks like natural stone and is in harmony with the environment.
