For larger operations, we have prepared a 60-person EKOL 9 wastewater treatment plant, which ensures safe and environmentally friendly wastewater treatment. With our innovative technology, you will achieve high treatment efficiency and reduce the negative impact on the environment.
Choose our powerful solution and ensure clean water for your however difficult operation. You can choose purifiers for less heavy-duty facilities, such as the EKOL 1, EKOL 2.5, EKOL 4 and EKOL 6, or for heavier-duty facilities, the EKOL 12 and EKOL 15.
Description and functions of the EKOL 9 wastewater treatment plant
The EKOL 9 consists of a tank made of wall elements and polypropylene plates, closed by 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.
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 emergent 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.
How to maintain the EKOL 9 sewage treatment plant
EKOL seriessewage treatment plants are maintenance-free. The great advantage is that their operation does not require daily servicing and their function will be maintained unless the power supply is interrupted. For optimum operation of the EKOL 9 maintenance-free sewage treatment plant, it is important to lubricate the bearings 2 times a year and drain the stored sludge once a year.
Where the EKOL 9 is used
Ideal for cases without a sewer connection, EKOL all-plastic mechanical-biological wastewater treatment plants are used to treat sewage from apartment buildings, recreational facilities, hotels, camping sites, social facilities, farms and factories for 60 equivalent persons.
The initial basis for the design and installation of WWTPs are the requirements of the water management authorities for the quality of water in the respective watercourse into which the treated wastewater is discharged, the requirements of investors and planning authorities.
