EKOL 1: sewage treatment plant for 7 persons

Ensure good quality clean water in your hotel or restaurant. The EKOL 1 maintenance-free purifier is designed for low hydraulic loads. Contribute to environmental protection in places where wastewater cannot be connected to the sewer system.

EKOL series wastewater treatment plants are used in places without a connection to the sewerage system. With the EKOL 1 sewage treatment plant you can ensure high quality clean water in hotels, restaurants and other smaller establishments with a hydraulic load of 1m³ of sewage/day. It is the optimal choice for up to 7 equivalent persons.

We also manufacture WWTPs suitable for larger hydraulic loads, making it easy to provide wastewater treatment for larger facilities. You can choose: a WWTP for 15 persons, for 25 persons, for 40 persons, for 60 persons, for 80 persons or even a variant for 100 persons.

Description and functions of the EKOL 1 wastewater treatment plant

The EKOL 1 consists of a tank enclosed by a split removable lid, which is made of wall elements and polypropylene plates. The lid contains ventilation and clearance holes for sludge removal and is non-penetrating.

The tank is divided into a primary sedimentation - settling area (A), a storage area (E), a biological treatment area (C) with a rotating biocontactor (B) and a settling area (D). The biological contactor consists of a cage filled with small plastic elements. The rotation of the rotor is provided by a drive unit consisting of a sliding gear box, a V-belt transmission, an electric motor with a distributor.

How the EKOL 1 wastewater treatment plant works

The treatment is integrated in one packaged unit, where there is both a mechanical treatment section (A,D,E) and a biological treatment section (B,C). Mechanical treatment is carried out in a two-chamber settling tank (A) by simple sedimentation. A part of this area near the bottom is reserved for anaerobic sludge stabilisation, thickening and storage (E). Pre-treated water flows into the biological treatment area (C) where the progressive TF/SC method, first introduced in the USA 15 years ago, is used.

This treatment method uses the activity of sessile and buoyant organisms. The composition of these microorganisms is so different that they are complementary in their effects. This results in a balanced treatment effect and at the same time a higher resistance to hydraulic and metabolic shocks compared to conventional wastewater treatment methods.

The activated mixture from the biozone (C) flows through a degassing chute into a vertical settling tank (D), which is connected to the biozone area (C) at the bottom. This ensures continuous dewatering of the settling tank (D) and the excess activated sludge is pumped back to the settling tank (A) by means of a wheel located on the periphery of the biorotor, where it is mixed with the freshly flowing polluted water.

In the settling and storage tank (A,E), the activated sludge flakes and the sludge water are separated and flow back together with the inflow to the biozone. In this way, communication between the biozone (C), the settling tank - septic tank (A) and the settling tank (D) is ensured. The clean water outlet trough from the settling tank (D) is equipped with adjustable brick walls to prevent floating suspended solids from the surface of the settling tank from escaping into the outlet.

Maintenance of the EKOL 1 sewage treatment plant

EKOL serieswastewater treatment plants are maintenance-free. They therefore do not require daily servicing and their function will be maintained unless the power supply is interrupted. The treatment plant only requires pumping out the stored sludge once a year and lubricating the bearings twice a year.

Where the EKOL 1 plastic sewage treatment plant is used

Ideal for cases without a sewer connection, the EKOL all-plastic mechanical-biological wastewater treatment plant is used to treat sewage from residential complexes, recreational facilities, hotels, campsites, social facilities, farms and factories for up to 7 equivalent persons.

The initial basis for the design and installation of WWTPs are the requirements of water management authorities for the quality of water in the relevant watercourse into which the treated wastewater is discharged, the requirements of investors and planning authorities.
