Biotal modular wastewater treatment plants – modern technologies in action

For nearly 20 years, BIOTAL has been engaged in the production of devices for water supply and sanitation management. Our most popular products are advanced biological treatment plants for household use. Our treatment plants are known for their high quality and efficiency in wastewater treatment. They operate based on activated sludge technology. Our modular treatment plants, in particular, have gained significant popularity. Today, they are considered the most effective and desirable in terms of environmental conservation.

Modular wastewater treatment plants: advantages

Our company offers a modern and innovative solution for water supply and sanitation that is perfectly suited for municipal services, residential complexes, small towns, and hotel-restaurant facilities. Our modular treatment plants have been specifically designed for deep biological treatment of domestic wastewater with a capacity ranging from 8 to 25 m3/day. We recommend using these plants in the following scenarios:

  • in case of low groundwater level;
  • in the presence of precast reinforced concrete elements.

Modular wastewater treatment plants – description process

Our biological treatment facilities are custom-made to meet the individual needs of each investor. We offer a modular design that allows for parallel expansion of the structures and increased productivity. The uniqueness of our block-module structures lies in their portable nature, making them easy to transport.

We utilize high-quality anti-corrosion materials such as stainless steel and polypropylene tanks, combined with advanced manufacturing technologies. This enables us to produce lightweight and easily transportable tanks that possess high mechanical strength and chemical resistance. Our structures are free from moving parts, ensuring high efficiency and durability.

We are ready to install our block-module facilities, “BIOTAL,” in any region of Ukraine, including Kyiv, Kharkiv, Odessa, Dnipro, Rivne, Lviv, and others.

Delivery is arranged individually for each client


BIOTAL wastewater treatment


Our unique underground modular units are designed for deep wastewater treatment ranging from 8 to 25 m³/day. They are suitable for locations with low groundwater levels and reinforced concrete elements.

Our units feature a simple and user-friendly design and can be easily installed underground. They are manufactured using high-quality materials, ensuring long-term durability.

We recommend our underground modular units for use in residential complexes, private homes, hotels, and similar locations. They will effectively treat wastewater and contribute to maintaining environmental cleanliness.


BIOTAL wastewater treatment


They are designed for treating large volumes of water ranging from 12 to 300 m³/day. If you have a high groundwater level, our units are the ideal solution as their underground part has a shallow depth while maintaining high productivity.

Our units are known for their high quality and durability, as they are made from reliable materials. They are also lightweight and easy to install and transport.

By choosing our modular units, you will get the most efficient solution for wastewater treatment at your facility. We are ready to work with you and provide the reliability and high quality you expect.

Clarification of terms

  • Dewatering block
    A dewatering block is used to reduce the volume of excess activated sludge.
  • Stainless steel screen for coarse debris retention
    Coarse debris is captured in the BIOTAL unit using a large stainless steel screen with dual-sided air scouring and a fixed cover.
  • Siphon airlift
    A device designed to transfer treated wastewater to the biofilter-settler, which prevents the entry of surface pollutants into the subsequent treatment zone.
  • Biological filter
    A self-cleaning biological filter that provides further treatment of wastewater and functions as a thin-layer settling tank.
  • Water level sensor
    Designed to provide timely signals to the automation system of the unit, which automatically switches the system to one of the seven programs, resulting in up to 70% energy savings.
  • UV disinfection
    The ultraviolet water disinfection unit is equipped with a UV-C lamp emitting at a wavelength of 254 nm.
  • Aerator
    The aerator is made of PUR membrane with laser perforations, enabling fine bubble aeration of wastewater. This increases the oxygen saturation efficiency of wastewater and enhances the absorption properties of activated sludge bacte.
