Guaranteed Treatment Efficiency
PRIMELOS equipment provides advanced treatment of domestic wastewater to meet strict discharge standards for fishery water bodies. Biological oxidation technology enables the removal of organic compounds and biogenic elements without the use of aggressive chemicals.

Primary Settling Chamber (First Chamber)
Wastewater enters the chamber either by gravity flow or under pressure. Under the influence of gravity, large suspended particles (sand, small debris, fibers) settle to the bottom, while heavy organic solids partially sediment and floating substances (fats, oils) accumulate on the surface.
Anaerobic Zone with Attached Growth Media and Low-Intensity Coarse-Bubble Aeration System (Second Chamber)
- Under limited oxygen conditions, anaerobic microorganisms attached to the media develop.
- Low-intensity coarse-bubble aeration (minimal air supply) creates microaerobic conditions that support denitrification (reduction of nitrates to gaseous nitrogen).
- Microorganisms break down complex organic compounds into simpler substances.
- Partial phosphorus removal occurs through its incorporation into bacterial biomass.
First-Stage Aeration Tank with Fine-Bubble Aeration System (Third Chamber)
- Fine-bubble aeration ensures uniform oxygen saturation of the water and keeps activated sludge suspended.
- Aerobic bacteria (within the activated sludge) actively oxidize organic pollutants.
- Nitrification takes place — oxidation of ammonium nitrogen into nitrates.
Second-Stage Aeration Tank with Attached Growth Media and Low-Intensity Fine-Bubble Aeration System (Fourth Chamber)
- A biofilm of microorganisms forms on the media, enhancing the performance of activated sludge.
- Low-intensity fine-bubble aeration maintains aerobic conditions without intensive mixing, promoting the development of specialized bacterial groups.
- Further oxidation of residual organic pollutants occurs.
- Additional oxidation of ammonium and nitrite compounds takes place.
- The treatment process becomes more stable and resistant to load fluctuations.
Settling Chamber with Airlifts for Excess Sludge and Sediment Removal, Treated Water Pump, and UV Disinfection Unit (Fifth Chamber)
- Поток замедляется, и активный ил оседает на дно.
- Эрлифты перекачивают избыточный активный ил и осадок: часть возвращается в предыдущие камеры (рециркуляция), часть удаляется на утилизацию.
- Очищенная вода поднимается в верхнюю часть камеры.
- Насос принудительно откачивает осветлённую воду на выход из станции.
- Перед сбросом вода проходит через установку УФ‑обеззараживания — ультрафиолетовое излучение уничтожает патогенные микроорганизмы, делая воду безопасной для сброса в водоёмы или повторного использования.

Hotels and Recreation Centers
Reliable operation under seasonal load fluctuations and complete elimination of unpleasant odors in recreational areas.
Industrial Facilities
Treatment of domestic and similar wastewater from administrative buildings and utility facilities of industrial enterprises.
Remote Camps and Military Settlements
Rapid deployment of treatment facilities in a modular format to support personnel operations in field conditions.

Frequently Asked Questions
No, this is not necessary. Activated sludge (colonies of microorganisms) develops naturally from incoming wastewater within 2–4 weeks after startup. Human involvement is only required to monitor the operation of the automation system.
Yes, PRIMELOS systems are designed to treat standard domestic wastewater, including wastewater from washing machines and dishwashers. We only recommend avoiding sudden discharges of aggressive chlorine-containing chemicals in high concentrations.
During short-term power outages (up to 4–6 hours), the bacteria enter a dormant state. In the event of longer interruptions, the biological environment may be partially affected, but thanks to the modular design and sludge recirculation system, full operation is typically restored within 24–48 hours after power is resumed.
Maintenance (removal of excess activated sludge) is usually required 1–2 times per year, depending on the operating intensity. The sludge is a biologically safe by-product and can be disposed of as fertilizer or removed by a sewage disposal truck.
