Block-modular (packaged) biological treatment plants PlanaOS-B-Block
Purification of domestic and similar wastewater.
Achievable cleaning standard — «fish farm».
Productivity 10…600 m3/day and more.
Block-modular (containerized) design.
Features and benefits of PlanaOS-B-Block stations:
- Version for the Far North and Arctic regions
- Maximum prefabrication units
- Reducing on-site installation
- Stainless tanks — service life up to 50 years
- Cleaning technologies SBR, MBBR, MBR
- Cold drain heating unit
- 100% redundancy of the main equipment
PlanaOS-B biological treatment stations are made in the form of block modules on a supporting frame. The built-in tanks represent a single unit with the supporting frame. The closed version of the stations provides comfortable year-round maintenance of treatment facilities and is the most suitable for the uninterrupted operation of equipment and production lines in the northern regions of Russia.

The PlanaOS-B-Block stations are designed for operation at temperatures up to -60 Celsius Deg. With and are equipped with reinforced insulation, a powerful supply and exhaust ventilation system with heated incoming air and heated valves, a vestibule and auxiliary rooms. Of course, the safety standards and corporate standards of the Customer are observed.

* Values in accordance with the requirements of ORDER No. 522 dated December 13, 2016 «On approval of water quality standards for water bodies of fishery significance, including standards for maximum permissible concentrations of harmful substances in the waters of water bodies of fishery significance.» The plant is not a source of excess pollution in terms of other controlled parameters.
** Achievement of the standards at the outlet is guaranteed provided that the following concentrations are not exceeded: sulfates ≤ 300 mg/dm3, chlorides ≤ 300 mg/dm3, dry residue ≤ 500 mg/dm3, and the absence of contaminants toxic to the biocenosis.
*** In case of unbalanced effluents (significant deviation from the condition BOD20/N/Р=100/5/1), nutrient solutions and biological preparations are additionally used.
We determine the configuration and cost of the station individually, based on your technical specification, the object and the project situation.
Upon your request, we will provide a technical passport, a technological solution, a dimensional solution, bindings and loads, a commercial offer for the supply and provision of services.
