Water is a critically important resource in mill facility operations, used intensively especially in wheat washing and tempering processes. Increasing water costs, limited water resources, and environmental sustainability requirements are directing mill facilities toward more efficient water use. Effective water management not only reduces operational costs but also minimizes environmental footprint and contributes to corporate sustainability goals. As Tanış A.Ş., with over 60 years of experience, we offer comprehensive solutions to increase water efficiency and improve sustainable water management in mill facilities.
Water Usage Areas in Mill Processes
Water usage in mill facilities occurs for various purposes in different processes. The main water usage areas are:
Wheat Washing and Tempering: This is the most intensive water usage point in mill facilities. In a typical facility, 100-150 liters of water per ton of wheat is used in the washing process, while 20-30 liters per ton is required for tempering.
Cleaning and Sanitation: The amount of water used for equipment and facility cleaning varies depending on facility size and cleaning procedures, but can constitute 15-20% of total water consumption.
Cooling and Heat Transfer Systems: Water used for cooling equipment such as motors, bearings, and rolls and controlling process heat can reach significant amounts, especially in open-loop systems.
Auxiliary Facilities and Social Areas: Water consumption in areas such as offices, cafeterias, showers, and toilets constitutes approximately 5-10% of total consumption.
The first step for effective water management is creating the facility’s water consumption profile. This process includes the following steps:
- Identification of Water Usage Points: Determining all water entry points, process usage areas, and discharge points
- Installation of Sub-meter Systems: Placing sub-meters at critical water usage points to measure consumption by department or process
- Data Collection and Analysis: Regular measurement, data recording, and trend analysis to detect abnormal consumption
- Benchmark Assessment: Comparison with industry averages and best practices
Installing 5-10 sub-meters at key water usage points in a medium-scale mill facility can create potential to reduce water consumption by 10-15%.
Water Balance Analysis and Loss Detection
Water balance analysis creates a mathematical model of all water flows entering and leaving a facility, enabling detection of losses and inefficiencies. The analysis includes the following steps:
- Determining total amount of water entering the facility (municipal, well, rainwater, etc.)
- Measuring or estimating consumption at all water usage points
- Measuring amount of discharged water
- Analyzing differences between incoming, used, and outgoing water amounts
More than 10% unexplained difference in water balance analysis indicates problems such as leakage, loss, or measurement issues. Regular loss detection programs can reduce water consumption by 5-15%.
Water Saving in Wheat Washing Systems
Wheat washing is one of the most water-consuming processes in mill facilities. Approaches that provide water savings include:
Efficient Washing Technologies: Modern, water-efficient washing systems can use 30-40% less water compared to traditional systems. High-pressure, low-volume nozzles and designs providing optimum water distribution reduce water consumption while maintaining washing effectiveness.
Washing Water Recycling: Reuse of washing water after filtration and treatment can reduce total water consumption by 50-60%. Staged counter-washing systems can use clean water for final rinse requiring cleaner water while using recovered water for pre-washing.
Dry Cleaning Combination: Effective pre-cleaning of wheat with advanced dry cleaning systems (stone separators, air classifiers, sieves) before washing reduces required water amount. This combination can reduce washing water consumption by 20-30%.
Water Optimization in Wheat Tempering Process
Tempering is critically important for yield and flour quality while being a significant water usage point. Recommendations for water optimization:
Precise Moisture Control: Advanced moisture sensors and control systems can automatically adjust tempering water amount based on wheat’s existing moisture content. These systems reduce water consumption by 10-15% while improving tempering quality.
Water Spraying Technologies: Micro nozzles and atomization systems create finer water droplets, providing more uniform water distribution on wheat grain surfaces. These technologies reduce water usage by 15-20% while increasing tempering effectiveness.
Two-stage Tempering: Two-stage tempering approach that shortens total tempering time and improves water penetration optimizes water usage while also providing energy savings.
Innovative tempering technologies developed in recent years provide significant improvements in water efficiency:
Ultrasonic-assisted Tempering: Ultrasonic technology accelerates water penetration and provides more uniform moisture distribution, shortening tempering time and reducing water consumption by 20-25%.
Steam Usage: Tempering with steam injection provides faster penetration and less total water consumption compared to liquid water usage. This technology offers advantages especially in high-capacity facilities.
Automatic Moisture Sensors and Feedback Systems: Systems providing real-time moisture measurement and dynamic water adjustment calculate optimum water amount based on wheat variety, initial moisture, and target moisture level, preventing excessive water usage.
Efficient Cleaning Procedures and Equipment
Facility cleaning is an important water usage area in mill operations. Efficient cleaning approaches include:
Low Water Consumption Cleaning Equipment: High-pressure, low-volume cleaning systems can provide up to 70% water savings compared to traditional hose washing. Spray heads and adjustable nozzles allow optimization of water amount according to usage purpose.
Dry Cleaning Methods: Vacuum cleaning systems, electrostatic cleaners, and compressed air cleaning provide effective cleaning without water usage, reducing water consumption. Especially for flour dust and dry contaminant cleaning, dry methods should be preferred.
Cleaning Planning and Optimization: Optimizing cleaning frequency and intensity according to actual need reduces water consumption. Risk-based cleaning programs reduce cleaning frequency for less critical areas while focusing on critical points in terms of food safety.
CIP (Clean-in-Place) System Optimization
CIP systems used in integrated mill facilities can provide significant water savings through efficient design and operation:
Efficient CIP Design: CIP systems designed with optimum tank sizing, low dead volume piping, and effective spray nozzles can reduce water consumption by 30-40% while maintaining cleaning effectiveness.
CIP Water Recovery: Collecting final rinse water and using it as pre-wash water in the next cleaning can reduce water consumption by 20-25%. With advanced filtration systems, the life of cleaning solutions can be extended, providing both water and chemical savings.
Optimum Cleaning Cycles: Optimizing CIP parameters (time, temperature, chemical concentration, flow rate) reduces water consumption while maintaining cleaning effectiveness. With sensors and automation systems, rinse time can be adjusted according to real-time contamination measurement.
Closed-loop Cooling Systems
Water used for equipment cooling can cause significant losses in open systems. Closed-loop systems minimize these losses:
Closed-loop Design: Closed systems where cooling water is continuously circulated and only evaporation losses are replenished consume 80-90% less water compared to open systems.
Open to Closed-loop Conversion: Converting existing open-loop cooling systems to closed-loop provides significant water savings. The payback period for this conversion typically varies between 1-3 years depending on water costs.
System Integrity: Maintaining system integrity through regular leak control, preventive maintenance, and appropriate water conditioning minimizes water losses.
Cooling Tower Optimization
Cooling towers are significant water consumption points in mill facilities. Optimization measures include:
Reducing Evaporation and Drift Losses: Modern drift eliminators and optimized designs can reduce water losses by 20-30%.
Blowdown Optimization: Unnecessary water discharge can be prevented through automatic conductivity control and optimum blowdown management, reducing water consumption by 10-15%. Recovery of blowdown water and its use in other applications (landscape irrigation, facility cleaning, etc.) is also possible.
Water Quality Management: System efficiency is increased through appropriate chemical dosing, filtration, and scale control, reducing water consumption. Advanced water treatment technologies increase circulation concentration ratio, reducing blowdown need and fresh water consumption.
Greywater Recovery Systems
Greywater (from sources such as showers, sinks, kitchens) can be reused in many applications after appropriate treatment:
Greywater Sources: Separate collection and treatment of water from sinks, showers, and kitchens in office and social areas creates an important resource that can be used as toilet reservoir water, landscape irrigation, or cleaning water.
Treatment Technologies: Technologies such as filtration, UV disinfection, and biological treatment are used for greywater treatment. System size and complexity vary according to facility size and reuse purpose.
Reuse Areas: Treated greywater can be used in areas such as toilet reservoirs, floor washing, vehicle washing, cooling tower make-up water, and landscape irrigation. In a typical facility, greywater recovery can reduce total water consumption by 15-20%.
Process Water Recycling Technologies
Recovery of water used in mill processes offers significant savings potential:
Filtration and Membrane Systems: Technologies such as sand filtration, microfiltration, ultrafiltration, and reverse osmosis enable treatment and reuse of process water. These systems are sized according to facility size and water quality requirements.
Washing Water Recovery: Reuse of wheat washing water after filtration and treatment can reduce total water consumption by 30-40%. Treatment systems typically include sedimentation, filtration, and disinfection steps.
Staged Usage Strategy: Using clean water in applications requiring high quality while using treated recovery water in less critical applications reduces total fresh water need.
