Like an autonomous sewage system, the ZIKO unit is designed for filtration and treatment of domestic wastewater. The system provides effective treatment of household effluent in locations where connection to a centralized sewer network is not possible — including summer houses, cottages, townhouses, and private residential buildings.
Configuration and Operating Principle of the ZIKO Domestic Wastewater Treatment Station
A compact and user-friendly domestic wastewater treatment station is easy to install. This allows savings in both financial and labor resources during preparatory and construction works. The technology developed by the engineers minimizes operational and maintenance costs throughout the service life of the unit.
The station consists of a single block in which domestic wastewater treatment is performed. If required, the unit can be additionally equipped with a drainage and accumulation system.
Completely safe and highly efficient biological wastewater treatment is carried out using aerobic and anaerobic microorganisms. These microorganisms consume products of human activity, soap residues, and surfactants contained in detergents. When supplied with sufficient oxygen and nutrients, bacteria effectively remove these contaminants from domestic wastewater.
Operating Principle of the Domestic Biological Treatment System
The operating principle of the ZIKO domestic wastewater treatment system is based on a combination of biological and mechanical treatment methods. The integration of anaerobic and aerobic processes is optimized to achieve a treatment efficiency of up to 98%:
- Coarse contaminants and sediment are removed in the mechanical treatment zone. This is ensured by the design of a dedicated basket-type chamber.
- The wastewater then enters the anaerobic zone, where active denitrification takes place, resulting in removal of the majority of organic contaminants.
- The next stage is the aeration zone, where the water is saturated with fine oxygen bubbles, enabling effective tertiary treatment.
- At the final stage, wastewater mixed with residual sludge enters the secondary clarifier, where sludge settles and is returned to the aeration zone via an airlift system. Purified water from the upper part of the clarifier is discharged into the drainage system.
Advantages of the ZIKO Domestic Biological Wastewater Treatment Unit
The simplest methods of domestic wastewater disposal in private houses or summer cottages are cesspools or septic tanks. However, cesspools can accept only a limited volume of wastewater and require 1–2 vacuum truck services per month. Depending on the region, this may cost 1,000 to 2,500 UAH per service.
In addition, unpleasant odors are constantly present on the property, and untreated wastewater infiltrates the soil, contaminating groundwater and negatively affecting the environment.
Septic tanks, despite their relatively low initial cost, also have several disadvantages:
- low level of wastewater treatment;
- high operating and maintenance costs;
- the need for additional equipment, which significantly increases system cost and footprint.
For these reasons, installation of the ZIKO system is strongly recommended.
Key advantages of the ZIKO domestic biological wastewater treatment unit include:
- high-quality filtration that eliminates unpleasant swamp-like odors around the property;
- treated water from the system can be used for household purposes and is safe, does not cause allergic reactions, and can be used even for small children;
- surrounding soil remains clean, as bacterially contaminated water does not enter the ground, protecting tree roots and ornamental plants;
- thanks to aerobic and anaerobic microorganisms, wastewater treatment operates in an automatic mode, without the need for constant supervision by homeowners.
The carefully engineered design enables the system to withstand peak hydraulic loads and efficiently treat wastewater during sudden discharge events.
Selecting the Optimal Model from the ZIKO Product Line
There are six versions of the ZIKO domestic biological wastewater treatment system:
- ZIKO 1.5
- ZIKO 3
- ZIKO 5
- ZIKO 10
- ZIKO 15
- ZIKO 20
When selecting a system with appropriate capacity and specifications, the following factors should be considered:
- the number of permanent residents in the house, including potential guests;
- the installation method of the selected model — into a frame structure or reinforced concrete rings.
Possibility of Expanding the System with Additional Equipment
If required, domestic wastewater treatment using the ZIKO system can be enhanced with additional equipment, including:
- forced wastewater pumping stations — used when the system is installed below the level of sewer outlets;
- receiving and distribution manholes — installed when a building has multiple sewer discharge points;
- systems for accumulation and drainage of treated wastewater into the soil.
