Biological Wastewater Treatment at Enterprises

ZIKO supplies a wide range of water treatment equipment with delivery across all regions of Ukraine, including water filters, reverse osmosis systems, and other equipment for effective water purification. The company also designs, develops, configures, and installs integrated biological wastewater treatment systems for industrial enterprises.

Industrial Wastewater

Depending on the type of manufactured products and technological processes, industrial wastewater can be divided into two main categories:

• Low-contaminated wastewater. Such water is most often used as a cooling medium.
• Contaminated wastewater — containing mechanical, organic (biological), or mineral (chemical) pollutants.

Accordingly, industrial wastewater may be low-concentration or high-concentration.

When discharged into soil or water bodies, such contaminated effluent causes irreparable damage to the environment, as well as to human and animal health. Therefore, high-quality industrial wastewater treatment is required to reduce the concentration of harmful contaminants to safe levels.

ZIKO Integrated Treatment Facilities

For treatment of low-concentration wastewater, proprietary ZIKO treatment units are used. The integrated ZIKO industrial wastewater treatment system reduces the concentration of a wide range of contaminants in water to permissible levels, including:

• suspended solids and ammonium nitrogen;
• vegetable and animal fats;
• sulfates;
• phosphates and chlorides;
• nitrites and nitrates.

The ZIKO integrated industrial wastewater treatment system ensures reduction of pollutant concentrations to values compliant with applicable regulatory standards. After treatment, the water can be reused for technical purposes or discharged into water bodies or onto soil.

Technological Scheme of Wastewater Treatment

The ZIKO integrated industrial wastewater treatment system consists of several functional units that ensure maximum purification of the effluent:

• Denitrification unit — simultaneous oxidation of organic substances by oxygen, reduction of nitrogen compounds, and release of nitrogen into the atmosphere.
• Aerobic bioreactor — artificial biological treatment of industrial wastewater using aeration and activated sludge.
• Aeration unit — maintenance of vital activity of activated sludge microorganisms.
• Air blower — supply of air at the pressure required for efficient system operation.
• Secondary clarifier — additional treatment and clarification of wastewater.
• Ozonator — disinfection of treated water using ozone.
• Dehydrator — dewatering and disposal of sludge.

The technology used for treatment of industrial wastewater has been developed in accordance with Technical Specifications TU U 42.2-38674771-008:201 and complies with all applicable national sanitary and hygienic standards.

Advantages of the System

The key advantages of the integrated treatment system include:

• high wastewater treatment efficiency regardless of the initial composition of the effluent;
• specially developed patented technology;
• silent operation and absence of unpleasant odors;
• minimal operating and maintenance costs;
• compact design.
