Expand your production without increasing your wastewater treatment civil works
Know your process
Do you know the source of all your wastewater? Identify the points where wastewater is produced. Know your process. Train your workers in reducing water use and apply basic housekeeping practices. For example, start with a dry mechanical intestines content removal instead of a wet removal step. In a broader perspective, aim to implement and optimize internal recycling. Perfect examples are using a fat skimmer or coarse screen. Another angle can be looking into water reuse. Reuse water may be drawn from the cooling towers, the defreeze of the cooling tunnel or the storage chambers.
Enhance your pretreatment
Once your factory water management has been optimized, the next step is to focus on pretreatment. Effective pretreatment plays a critical role in reducing the amount of pollution entering the biological treatment stage. Techniques like advanced screening, grit removal, and chemical precipitation can effectively remove pollution before they reach the biological system. This reduces the strain on microorganisms, resulting in better performance and lower energy consumption.
Improve biomass utilization
Upgrading your biological treatment does not necessarily mean additional civil works. Before opting for large-scale infrastructure changes, first assess whether existing equipment can be expanded. Add auxiliary equipment to ensure that your biological system can operate without additional tank volume. For example, by adding mixers or aeration racks.
For substantial increase of your biological load capacity, upgrades of your sludge separation technique may prove useful. Some technologies enable more efficient treatment with smaller footprints. Switching from a clarifier system to a sludge flotation system or transitioning from a discontinuous batch system to continuous system can boost the load capacity more than fifty percent.
Repurpose existing infrastructure
By creatively leveraging your existing systems, you can manage the increased wastewater flow without the need for major construction projects. For example, reusing an existing clarifier tank as a balancing tank can significantly level out flow and load thus reduce investment costs. Unused tanks may prove useful for storing required wastewater during emergencies.
By optimizing key aspects such as factory water management, pretreatment, biological treatment and civil works utilization, you can significantly increase your plant’s production without adding civil works to the wastewater treatment system.
