Coskun Aritim San. ve Tic. A.S.
About
Coskun Arıtma A.Ş. is a Turkish environmental technology company founded in 2005 and headquartered in Dilovası, Kocaeli. The company designs, manufactures, installs, and commissions water and wastewater treatment systems on a turnkey basis, with international offices in Germany, Albania, Kosovo, Iraq, and Libya. Operating from a dedicated factory facility, Coskun has delivered projects for NATO, IPA, and UNDP. The company's flagship product line is BioCAS, a branded range of compact packaged biological treatment systems offered in three process configurations: SBR (Sequential Batch Reactor), MBBR (Moving Bed Biofilm Reactor), and MBR (Membrane Bioreactor). Beyond package plants, Coskun manufactures a broad equipment portfolio including DAF dissolved air flotation units, reverse osmosis and ultrafiltration membrane systems, pressurized sand and activated carbon filters, belt and filter presses for sludge dewatering, screening presses, circular and longitudinal scraper bridges, grit classifiers, jet and surface aerators, flash and slow mixers, penstock covers, lifting stations, drum sieves, and polyelectrolyte preparation units. Coskun also produces bentonite treatment plants for construction-site excavation water and river water treatment systems for small settlements. The company provides comprehensive maintenance and service programs covering its own installations as well as third-party plants, including regulatory compliance updates, efficiency monitoring, and electromechanical maintenance.
Key Products
Package biological wastewater treatment units in circular, prismatic, or reinforced concrete configurations, designed to demand for small settlements and decentralized applications.
Compact biological treatment using thousands of polyethylene biofilm carriers operating in mixed motion in aerated tanks under PLC control for BOD and nitrogen removal.
High-efficiency modern treatment technology combining biological treatment with membrane filtration for superior effluent quality in a compact footprint.
Reinforced concrete or compact factory-made systems for producing clean drinking water from river sources for small settlements, towns, and villages.
Systems for treating wastewater containing high levels of industrial and chemical pollution using chemical precipitation, coagulation, and advanced oxidation processes.
Separates solids, oil, and grease from wastewater using dissolved air flotation, providing significant reduction in COD and BOD for industrial and municipal applications.
Semi-permeable membrane systems that remove dissolved impurities at a molecular level, producing high-purity water from challenging source waters.
Semi-permeable membrane systems removing suspended solids, bacteria, and viruses for high-precision water purification.
Compact treatment units in varying capacities for bentonite-intensive wastewater from construction site excavation works.
Aeration and mixing device for activated sludge tanks, injecting air directly into the mixed liquor for oxygen transfer and mixing.
Horizontal rotating discs with peripheral blades for surface mixing and aeration in biological treatment tanks.
Floating version of the surface aerator for flexible positioning within treatment basins.
Proprietary in-house design brush aerator for oxidation ditch and channel configurations, installed in numerous plants.
Removes suspended solids and turbidity from water through pressurized sand media filtration.
Activated carbon filtration for adsorption of organic compounds, color, and odor from water, used in water softening systems.
Sludge thickening and dewatering equipment using dual-belt pressing for volume reduction of waste sludge.
Sludge dewatering through compression between filter cloths on press plates, producing high-dryness sludge cake.
Transfers solid waste from coarse and fine mechanical screens to bins by pressing, reducing volume and water content of screenings.
Sedimentation equipment for high-flowrate municipal wastewater and potable water plants, available in circular and rectangular basin configurations.
Chemical or biological removal of air pollutants from wastewater treatment processes, designed for low energy consumption.
Coarse and fine screening at intake structures to remove solids from incoming wastewater flow.
Compact system that separates large materials, sand, and grease from domestic and industrial wastewater in a single unit.
Removes grit and sand-like objects at the first intake structure of wastewater treatment plants for equipment protection.
Fully factory-built compact plants for wastewater transfer where gravity flow is insufficient, with integrated pumps and controls.
Coagulation units for rapid mixing (flash) and slow mixing (flocculation) in chemical wastewater treatment, plus chemical solution preparation tanks.
Prepares polymer solutions for sludge conditioning and dewatering, addressing blockages and improving sludge dewaterability.
Valves controlling water flow direction in treatment channels and walls, available with manual or actuator operation.
Expansion and water hammer arrestor tanks with replaceable membranes for potable water and HVAC systems, corrosion-resistant design.
Fine screening equipment that catches and removes small objects at the first inlet structure of wastewater treatment plants.
