Waste Water Treatment


Wastewater, in the most general terms, is contaminated water that is responsible for domestic, industrial, commercial or agricultural activities as a result of humans. The properties of waste water vary depending on the source. Wastewater contains physical, chemical and biological contaminants. Treatment of wastewater can be done by physical, chemical and biological means in parallel with the pollutants it contains:


Chemical treatment is formed by the addition of various chemicals in the fast and slowing units of the waste water and the precipitation of these chemicals by reacting with the contaminants in the waste water.


Biological treatment, filling domestic or wastewater with biodegradation with the help of bacteria with or without oxygen.


Physical treatment is the removal of oil and coarse wastes in the wastewater by means of mechanical processes, without using any chemicals or bacteria, with screens, oil scraper pallets and similar devices.


Generally, a biological wastewater treatment plant consist of inlet pumping station, coarse and fine screen unit, sand and oil holding unit, balancing, pre-sedimentation, aeration pool, excess sludge and return pumping station, final settling expedition, sludge thickening unit, sludge dewatering unit and disinfection unit.


As Arpon, we serve with our wide range of washing wastewater treatment processes.


Wastewater collected at wastewater pumping stations is transferred to wastewater treatment plant by ZENIT submersible wastewater pumps. ZENIT high efficiency submersible pumps provide trouble-free solutions with low energy for years. ZENIT submersible pumps have different impeller types and materials specifically for different applications.


At the inlet pumping stations, the wastewater is pumped with ZENIT submersible pumps.


In the sand and oil collection, ZENIT vortex sand pumps are used integrated to the moving bridge to transfer the settled sand to the sand separator.


Similarly, the oils accumulated on the surface in the sand and oil holder unit are scraped off by the moving bridge and transferred by ZENIT vortex oil pumps.


In the balancing tanks, some of them will be tested for wastewater promotion. These applications are also successful with ZENIT submersible pumping pumps.


In the pre-settling tanks, some AKM and BOD are removed to reduce the load on the aeration tank. OBL diaphragm dosing pumps and VERDER air diaphragm pumps can be used in the dosage of chemicals for this removal.


In the aeration pools, oxygen flow is provided to the wastewater with SSI diffusers placed on the pool floor. Compressed air transferred to the diffusers is provided by CONTINENTAL turbo blowers.
