Conical / Clarifier Holding Tank
A water filtration system is designed to remove solid particles and clarify water as part of a closed-loop water process. Conical holding tanks are a critical part of the stone fabrication water recycling process and hold grey water until it’s ready to be filtered and clarified.
Discover how a conical/clarifier holding tank operates in this system and how a BACA Pure system can improve your large- or small-scale stone polishing or cutting industrial process.
How a Conical/Clarifier Holding Tank Works
Clarifier / clarification water tanks hold grey water after the water has been processed by hydrocyclones. These tanks come in a wide range of sizes to accommodate the amount of water needed in your stone manufacturing process. They can be used to provide clarified water to a single machine or as part of a multi-machine water recycling setup. The shape of a clarification tank can vary, but most feature a conical bottom.
A conical/clarifier holding tank, by using a conical shape, starts the sedimentation process. Sedimentation is part of the primary treatment process, also known as the mechanical treatment process. Secondary clarifiers work with this process to filter out debris 10 microns or smaller. This process allows the water used in your stone cutting process to be safely recycled in a closed-loop system.
The goal of this system is to reduce the amount of water used in your manufacturing process. Stone cutting and polishing machines require a significant amount of water to cool down blades and reduce friction. Continuously pumping new water into your machine not only increases your water costs, but can also create environmental concerns. Enjoy an efficient, affordable process with a conical/clarifier holding tank as part of a full water filtration system.
An appropriately sized conical/clarifier holding tank holds enough grey water to allow the primary treatment method to reduce the biological oxygen demand by up to 30%. The suspended solid total is reduced by up to 60%. This process still isn’t enough to properly recycle the water, but it provides a critical step in the process that allows your cyclone filtration system and hydrocyclones to achieve optimal water purity.
The secondary clarification system works best when the large elements are removed during primary settlement. Grey water from the holding tank runs through a settling weir and sludge hopper to remove a significant amount of the suspended solids from the water. A cyclone filtration system filters the water further before sending it to hydrocyclones and the clarifier holding tank.
Some settling tanks work as secondary clarifiers. These remove biological growth and continue to clarify the wastewater until it reaches acceptable purity levels to be recycled in CNC stone cutter or stone polishing equipment. Discuss your primary and secondary clarification needs to determine the best tank size and type for your application.
Sizing Your Clarification Tank
A clarification tank on its own isn’t capable of delivering water ready to be reused in your equipment. These commercial tanks are only a single step in a multi-step water filtration and recycling process. A BACA Pure system includes hydrocyclones, a sludge hopper, settling weir and holding tank perfectly balanced to ensure peak efficiency of your recycling process.
Work with our team at BACA Systems to identify the ideal conical/clarifier holding tank size for your application. We carefully analyze the size of your water filtration system, the flow rate of various filters and the amount of water necessary for your industrial equipment.
An incorrect clarification tank can prevent full water pressure as part of the closed-loop process. A large tank may be unnecessary for your water usage and take up additional shop space.
