High-concentration bentonite wastewater can be separated into solid and liquid phases.
Until now, there have been very few methods to separate water from high-concentration bentonite wastewater using coagulants. With the combination of Ultra Separate BC and diluted hydrochloric acid, high-concentration bentonite wastewater can be easily treated. For dewatering, a cloth filter type simple dewatering machine is optimal. When treating bentonite wastewater with coagulation, it expands and contracts, resulting in strong additional resistance, making it impossible to process with standard coagulation sedimentation equipment. Our company has developed a coagulation sedimentation device specifically for treating bentonite wastewater.

basic information
Overview of Ultra Separate BC. Ultra Separate BC is a user-friendly alkaline mineral-based powder coagulant newly developed for bentonite wastewater treatment. When added to bentonite wastewater and used in conjunction with diluted hydrochloric acid while stirring, it forms flocs while strongly dissolving the bentonite, allowing for solid-liquid separation. The flocs are remarkably large, and the treated water is clear and neutral. Advantages of Ultra Separate BC. ● The flocs are large, reducing the volume to less than one-third simply by draining the water. ● The treated water is surprisingly clear and neutral. ● The coagulation and sedimentation speed is fast, effectively dissolving bentonite and achieving strong solid-liquid separation. ● The flocs are stable, preventing the re-separation of contaminants.

Applications/Examples of results
Until now, there have been very few agents capable of separating solid and liquid from highly concentrated bentonite wastewater using coagulants. Ultra Separate BC is a coagulant developed at the request of a major drilling contractor. It is highly effective for solid-liquid separation of bentonite wastewater. Ultra Separate BC has a proven track record in the treatment of wastewater from drilling operations and in the intermediate treatment of bentonite wastewater. The treatment method involves diluting the bentonite wastewater with 1 to 2 times the amount of water, adding a small amount of Ultra Separate BC, and stirring for about ten minutes. Then, hydrochloric acid dilution is added and stirred, resulting in solid-liquid separation within a few minutes. The floc can easily be drained, reducing the volume to less than one-third through simple drainage. When the cake is dried in the sun, it can be reduced by up to 13%, and since it does not re-sludge even when exposed to rainwater, no solidifying agent is necessary. The treated water can be discharged or reused as dilution water. Our company has also developed and sells a simple dewatering machine. Additionally, since the treatment of bentonite wastewater involves significant additional resistance due to the processes of expansion, dissolution, and coagulation, we have developed a three-dimensional water flow stirring coagulation sedimentation device equipped with a powerful stirrer specifically for bentonite wastewater.

Company information
Our company is small, but we have applied for patents for electric dust collectors and sludge solidification treatment devices. Currently, we are providing environmental purification technology consulting based on cutting-edge environmental purification technology, as well as developing and planning environmental purification devices. We have developed and are selling environmental purification products such as the dioxin removal coagulant Ultra Separate SDS, the heavy metal removal coagulant Ultra Separate S300, and the turbidity coagulant Ultra Separate MC, which is effective for a wide range of applications from organic wastewater to the purification of lake water quality. We are also currently selling a dihydrate gypsum semi-hydration device that can convert waste gypsum boards after crushing and separation into recyclable raw materials. We are developing solidifying agents for soil conditioners, high-moisture sludge, and sludge containing heavy metals, utilizing the semi-hydrated gypsum produced from the dihydrate gypsum semi-hydration device, and we plan to sell these as well. We intend to continue developing products and goods based on environmental purification technology in the future.
