Waste water treatment to receiving water quality
SBR technology
In 1996, a well-known international so drink producer has built a large beverage production plant as a green eld project in Ukraine. The waste water, originating from production, processing and bottling is fed into a SBR system and treated up to receiving water quality. Within the framework the plant was extended in 2010 as part of a second construction phase.
Numbers & Facts:
• Task: Production waste water treatment from a beverage production plant.
• Location: Ukraine
• Time: Stage 1 completed in 1996, Stage 2 completed in 2010
• Performance scope: Turnkey project: Planning and execution of civil engineering, detail engineering, Approval procedures, Delivery of machinery, containers and electrical components, EMSR technology and control system, Installation of the components, Commissioning and training of personnel
Scope of work:
Using of SBR technology is an excellent choice for processing waste water that contains a large amount of organic pollutants. It is costeffective, reliable and furthermore, it requires little space. For such scope of work, CUSS has been developed processing concepts for years that are exactly tailored to individual customer’s requests. Waste water quality, discharge regulations and client’s requirements are guiding factors in the choice of process. Our target is an e fficient and state-of-the-art waste water treatment.
Solutions are developed, quoted and realized, based upon more than 20 years of experience and a multitude of applications.
Wastewater components:
- Sugar and other organic substances
- Residue from storage, processing and bottling
- Glue and solid substances as well as alkaline solutions and acids from bottle cleaning
- Mineral-based grease
Processing steps:
- Physical treatment
- pH adjustment
- SBR activation
- Treatment of sludge
- High-performance filtration
- Disinfection of discharge
- Discharge via a representative fish pond
Process description
In a first physical processing step coarse substances as well as grease and oil are separated. After neutralization and homogenization phase the wastewater is fed into the SBR reactor. The biological treatment takes place by eliminating organic waste content. Dissolved organic substances are converted into undissolved biomass and can thus be removed via sedimentation of the activated sludge. The excess sludge is thickened and can be disposed in an inexpensive and reliable way. This is an effective and proven method since years. Owing to the biological treatment the BOD intake concentrations are reduced from 2000 mg/l to discharge concentrations of 1-3 mg/l. Since commissioning in 1996 customer’s satisfaction has been very high. This led to a follow-up order for CUSS when the plant expansion was planned in 2010. The entire second construction phase was implemented during operation without interrupting the main process. After 14 years of operation, the high-quality main components are still performing very well and were thus integrated into the process. Now a maximum of 5250 m³/d of wastewater can be treated with the expanded plant.
Customer benefits
• low reactor volume required
• all process stages in one container
• simple and low-maintenance process technology
• low investment and operating costs
• accurate control of wastewater treatment processes.
• adaptable process design: implementation of an anoxic phase, reactors may be in parallel or in series, thus it is easy to adapt the process to changing intake parameters
