I. Project Background
The customer for this cooperation is based in Lebanon, with the core demand of treating and filtering bottle washing wastewater to achieve recycling and reuse. This not only meets environmental protection and emission reduction requirements but also reduces water resource consumption and production costs. The customer clearly stated that the solid impurities in the wastewater to be treated are mainly sand and a small amount of plastic particles. Meanwhile, specific standards for equipment material, function and treatment efficiency were put forward to adapt to the continuous operation needs of its production scenario and ensure filtration effect and equipment durability.
II. Core Customer Requirements
- Treatment Object: Bottle washing wastewater; sand, a small amount of plastic particles and other solid impurities need to be filtered out to realize wastewater recycling and reuse.
- Material Requirement: 316L stainless steel is specified to adapt to the wastewater environment, avoid corrosion and aging, and ensure long-term stable operation of the equipment and water quality hygiene.
- Function Requirement: Equipped with automatic cleaning function to reduce manual maintenance workload, adapt to continuous production scenarios, and avoid frequent shutdowns for manual cleaning.
- Treatment Efficiency: The wastewater treatment flow rate is required to reach 30m³/h, so as to meet the rhythm of wastewater discharge and recycling in the production process without affecting normal production progress.
III. Scheme Selection and Adaptability Analysis
Combined with the customer’s needs and the impurity characteristics of the wastewater to be treated, we recommended a mesh-type self-cleaning filter to the customer after targeted research and judgment. This equipment can accurately meet various requirements, with core adaptability as follows:
(I) Material Adaptability: 316L Stainless Steel Lays a Solid Foundation for Durability
In strict accordance with the customer’s specification, all core components of the equipment are made of 316L stainless steel. Compared with ordinary stainless steel, 316L stainless steel has excellent corrosion resistance, wear resistance and high-temperature resistance. It can effectively resist trace chemical residues and impurity friction loss that may be contained in bottle washing wastewater, avoid water pollution or equipment failure caused by equipment rust and damage, greatly extend the service life of the equipment, and adapt to long-term wastewater treatment scenarios.
(II) Function Adaptability: Automatic Cleaning Meets Continuous Production
The equipment is equipped with a full-automatic cleaning system, which can complete filter screen cleaning without manual intervention. When the filter screen is blocked by sand and plastic particles and the pressure difference increases, the equipment will automatically trigger the cleaning program, peel off and discharge impurities through backwashing. The cleaning process is fast and efficient, and no shutdown is required, which perfectly meets the customer’s demand for continuous production, reduces manual maintenance costs, and avoids production interruption caused by manual cleaning.
(III) Filtration and Efficiency Adaptability: Precise Impurity Removal + Standard Flow Rate
The mesh-type filtration structure can accurately intercept sand and a small amount of plastic particles in the water, with controllable filtration precision. It can effectively remove solid impurities in the wastewater, ensure that the recycled water quality meets the standards, and meet the requirements of recycling in the bottle washing process. At the same time, the equipment is designed to adapt to a treatment flow rate of 30m³/h, with stable flow rate and no fluctuation, which can synchronously match the amount of wastewater generated in the customer’s production process, realize real-time wastewater treatment and immediate recycling, and not slow down the production rhythm.
IV. Project Implementation and Operation Effect
(I) Project Implementation
According to the customer’s on-site production layout and wastewater treatment conditions, we completed the customized production, inspection, commissioning and on-site installation and docking of the mesh-type self-cleaning filter. We strictly controlled the quality inspection of 316L stainless steel throughout the process to ensure that all performance indicators of the equipment meet the customer’s requirements. After installation, multiple rounds of trial operation and commissioning were carried out to optimize equipment operation parameters and ensure seamless connection between the equipment and the customer’s existing production system.
(II) Operation Effect
- Qualified Filtration Effect: After the stable operation of the equipment, it can efficiently intercept sand and plastic particles in the bottle washing wastewater. The filtered recycled water is clear and free of obvious solid impurities, which fully meets the recycling standards of the bottle washing process and realizes the resource utilization of wastewater.
- Stable and Controllable Flow Rate: The treatment flow rate of 30m³/h is maintained throughout, which is accurately matched with the customer’s production rhythm. There is no flow attenuation problem, ensuring the continuous progress of the production process, and no production stagnation caused by untimely wastewater treatment.
- Reduced Maintenance Costs: The automatic cleaning function effectively replaces manual cleaning, greatly reducing manual workload and maintenance time. At the same time, the durability of 316L stainless steel reduces equipment loss and the frequency of parts replacement, and the long-term operation cost is significantly reduced.
- Win-Win of Environmental Protection and Benefits: Through wastewater recycling and reuse, the consumption of fresh water resources is reduced, and the total amount of wastewater discharge is also reduced. This not only meets environmental protection requirements but also saves the customer’s water resource procurement costs, achieving a double improvement in environmental and economic benefits.
V. Customer Feedback
After the project was put into operation, the equipment operated stably and reliably, and all performance indicators met the preset standards. The customer highly recognized the filtration effect, operation efficiency and automatic cleaning function of the mesh-type self-cleaning filter. They believed that the equipment accurately met their production needs, the selection of 316L stainless steel ensured the long-term durability of the equipment in the wastewater environment, and the wastewater recycling and reuse mode effectively reduced production costs and brought tangible benefits to the enterprise. The customer fully affirmed this cooperation and the solution.
VI. Project Summary
The customized solution for the Lebanese customer’s bottle washing wastewater recycling and reuse takes the mesh-type self-cleaning filter as the core, strictly meets the customer’s specified requirements for material, function and efficiency, and accurately solves the pain points of bottle washing wastewater treatment and resource utilization. The durability of 316L stainless steel, the convenience of automatic cleaning and the high treatment capacity of 30m³/h perfectly adapt to the customer’s continuous production scenario. It not only achieves the goal of environmental protection and emission reduction but also helps the customer control production costs, demonstrating the pertinence and practicality of the solution. It also provides reference practical experience for similar bottle washing wastewater treatment and recycling projects.
