The waste water treatment plant was constructed according to the technical documentation of the Institute for the Town Planning in Novi Sad in 1974. The plant was started up in 1989. The objects of waste water treatment plant are on two locations, about 800 m away from each other. The wastewater treatment is based on biologically active mud. The treated wastewater collector is the Bezdan-Bečej Canal . The construction of this wastewater plant was conducted in phases, depending on the incoming wastewater quantity and quality.
The plant for treatment of waste water is designed with the final goal to get the effluent characteristics from 25 mg BPK5/l of dehydrated and stabilized mud.
On the basis of constructed facilities ( 1 st phase ) the wastewater treatment plant can be loaded up to next limits:
- Hydraulic Q=7750m3/ day
- Organic R=3000 kg BOC5/day
- Equivalent population number 50.000
- The water purification is up to 80-90%.
The waste water treatment plant lacks:
- sand filter and grease filter
- primary sedimentation device
- incoming raw water and outgoing treated water flow meters
- mud dehydration
- filter press
It also lacks centrifugal pumps for transferring of mud from the aeration pool and of surplus of mud into the mud silo.
Current problems
- it is necessary to reconstruct the main suction station of waste waters in order to receive additional quantities of waste waters from industry and citizens
- lack of aerated sand filter and grease filter, primary sedimentation device, secondary sedimentation device, snail suction device, incoming raw water and outgoing treated water flow gauges, mud silo, mud dehydration-filter press, continuous oxygen measuring in the aeration pools
- lack of centrifugal pump for the transferring of mud from the pool for the aeration of surplus of mud into the mud silo
- it is necessary to rebuild the existing laboratory building and control room
- it is necessary to construct sanitary facilities, changing room and laundry for working clothes
- lack of device for receiving of liquid waste water from septic pits and industrial plants
Elements of development
- reconstruction of the main suction station
- construction of aerated sand filter and grease filter Q= 7750 m3/day
- acquisition of waste water flow gauges (inductive or ultrasound)
- acquisition of equipment for continuous oxygen measuring
- acquisition of equipment for mud dehydration (filter press) Q= 9 m3/hour
- acquisition of centrifugal pump for mud Q= 15 l/s, H= 16 m
- construction of device for receiving of liquid waste water
- rebuilding of existing laboratory building and control room
- construction of sanitary facilities, changing room and laundry for working clothes
