EKOL 6: wastewater treatment plant for 40 people

Highly reliable and efficient sewage treatment plant for 40 people. Ideal choice for medium-sized buildings. With our innovative technology, you will achieve trouble-free and environmentally friendly wastewater treatment.

The 40-person wastewater treatment plant is a suitable solution for medium-sized buildings such as apartment buildings, hotels, restaurants and other establishments. With a capacity of 40 people, it provides reliable and maintenance-free wastewater treatment even in places without a connection to the sewage system.

You can also choose from our wide range of sewage treatment plants for less loaded facilities, such as the EKOL 1, EKOL 2.5 or EKOL 4, as well as for more loaded facilities, such as the EKOL 9, EKOL 12 or EKOL 15.

Description and function of the EKOL 6 wastewater treatment plant

The core of the EKOL 6 is the tank, which is made of wall elements and polypropylene plates, closed with a split removable lid. The lid contains ventilation and clearing holes for sludge removal and is non-penetrating.

The tank is divided into a primary sedimentation area - 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 does the wastewater treatment plant (WWTP) work?

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 double 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 micro-organisms 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 6 wastewater treatment plant

EKOL maintenance-free wastewater treatment plants are great in that they do not require daily servicing. Their function will be maintained as long as there is no interruption in the power supply. The EKOL 6 WWTP requires lubrication of the bearings 2 times a year and draining of the stored sludge 1 time a year for optimal operation.

Where the EKOL 6 is used

EKOL plastic mechanical-biological wastewater treatment plants are ideal for applications where there is no connection to the sewer system. They are primarily used for the treatment of sewage from residential complexes, recreational facilities, hotels, campsites, social facilities, farms and factories for 40 equivalent persons.

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