[Case] Purification experiment of salmon farming at 60m depth in the Magellan Strait, Chile.

[Case] Purification experiment of salmon farming at 60m depth in the Magellan Strait, Chile.

In the experiment, we are using a "400L/min OK nozzle" to inject fine bubbles into the seabed!

As part of the Magellan Strait seabed purification experiment, we are currently conducting seabed purification experiments in the Magellan Strait of Chile, and we are seeing good results. In Chile, salmon farming has been carried out in the strait's bays for many years, leading to the accumulation of leftover feed and waste on the seabed, which has deteriorated the environment to the point where it is no longer suitable for salmon farming. The project, carried out by the responsible parties in collaboration with aquaculture operators, aims to purify the seabed so that salmon farming can be resumed. Fish farming is taking place in bays around the world, facing similar issues to those in Chile, to varying degrees. Therefore, the results of this experiment are expected to be disseminated globally. Here, we summarize the content of email exchanges regarding the experiments conducted by the responsible parties, and we also provide our own suggestions on the 300m seabed purification method. *For detailed information on the case, please refer to the related links.

[Example] Custom nozzle with a small flow rate of 500 mL/min

[Example] Custom nozzle with a small flow rate of 500 mL/min

Manufactured a 500mL/min nozzle! Adjusted to increase vacuum level, resulting in an increase in bubble generation.

We would like to introduce a case study using the '500mL/min small custom nozzle' from OK Engineering Co., Ltd. In July 2011, at a water pressure of 0.15MPa, the discharge rate was 410mL/min, and the vacuum level was approximately -0.03MPa under normal settings. A 500mL/min nozzle was manufactured, and adjustments were made to increase the vacuum level at the nozzle agitation section to -0.09MPa when the water pressure was 0.25MPa, resulting in a slight increase in bubble generation. Currently, we are ensuring that the vacuum level of the nozzle exceeds -0.05MPa at a water pressure of 0.15MPa. [Case Summary] <July 2011> ■ A 500mL/min nozzle was manufactured. ■ Since the generation amount is low, it is necessary to increase the vacuum level if required. ■ Adjusted to increase the vacuum level to -0.09MPa at a water pressure of 0.25MPa. ■ There was a slight increase in bubble generation. *For more detailed information about the case, please refer to the related links.

Floating separation microbubble generation device "YJ-FT" for floating treatment in wastewater treatment.

Floating separation microbubble generation device "YJ-FT" for floating treatment in wastewater treatment.

By simply using a floating separation ejector with the microbubble generator YJ, performance is significantly improved. Maintenance-free and reduced water quality due to microbubble collapse.

The floating separation micro-nano bubble generation nozzle device "YJ-FT" is a revolutionary microbubble generation nozzle that improves efficiency and stabilizes operations by simply installing a micro-nano bubble generation device at the inlet of a pressurized tank, replacing the conventional ejector. It is maintenance-free and reduces the BOD of treated water through the decomposition of organic matter caused by pressure collapse. The installation methods for the floating separation micro-nano bubble generation nozzle "YJ-FT" are: 1. Installation at the inlet of the pressurized tank, and 2. Providing a bypass line from the pump outlet to the suction side and installing it on the suction side. If the pump has spare pressure capacity, option 1 is recommended; if not, option 2 is preferable. By attaching the floating separation micro-nano bubble YJ nozzle to the existing pressurized tank inlet and simply drawing compressor air into the nozzle's intake, the pressurized floating device is stabilized. By injecting oxygen or ozone into the floating separation micro-fine bubble generation device YJ nozzle instead of air, the collapse effect can be further enhanced, allowing for greater reductions in BOD and COD. Particularly, significant effects can be achieved by introducing ozone. For more details on the micro-nano bubble generation device YJ nozzle, please download the catalog.

In development: Microbubble generation nozzle using sintered metal

In development: Microbubble generation nozzle using sintered metal

Developing a microbubble generation nozzle using a sintered metal filter element. Gas piping! Automatic liquid suction → No pump needed! No high-pressure pump needed!

At Sintering.com, we are focusing on micro-bubbling as our top priority and advancing its development. Micro-bubbling does not simply occur by passing through fine pores; rather, if the bubbles only pass through small holes, they do not become microbubbles. On the contrary, this leads to significant pressure loss and a marked decline in performance. Therefore, we are embarking on the development of microbubble generation nozzles using sintered metals, combining this with the metal processing technology that has been the foundation of our company since its inception. Many nozzles currently on the market circulate water (liquid) through piping using pumps, and further high-pressure pumps are employed. This naturally incurs equipment costs and requires installation space. Additionally, piping with water (liquid) increases the risk of leaks, necessitating attention to the surrounding environment. High-pressure pumps can be noisy, and noise control measures may be required in some cases. At Sintering.com, we are developing micro-bubbling based on gas piping and are working on a user-friendly micro-bubbling nozzle that minimizes user equipment by adding an automatic suction function for the solution (liquid) directly to the nozzle, eliminating the need for circulation pumps and high-pressure pumps.
