● Increased treatment volume of dialysis wastewater and replacement of neutralization treatment equipment We received an inquiry from a clinic in the Kansai region regarding the update of neutralization equipment due to the increase in dialysis wastewater treatment volume. The existing system was a neutralization treatment device from Company T, but due to a greater emphasis on responsiveness rather than price advantages, they decided to consider and place an order for our replacement. Since the site had limited space, it was necessary to devise a solution, such as splitting the raw water tank into two, to neutralize the increased treatment volume. ● Installation of neutralization equipment that meets treatment volume requirements in limited space The neutralization was done on both the alkaline side with caustic soda and the acidic side with dilute sulfuric acid, using our company's chemical injection pump. Thanks to its stable performance, it was operated with just one unit, eliminating the need for a backup machine. Additionally, the control panel size was compacted to about half of the conventional size, contributing to space-saving. The transfer from the raw water was also done using a submersible pump instead of a land pump, further saving space. Maintenance space was adequately provided, taking into consideration future electrode calibration and regular maintenance handling.

We received an order for the pH neutralization treatment, including construction, due to the addition of a new line from a food factory. All tanks were selected as heat-resistant tanks (80°C) due to the high-temperature wastewater. The pH meter was also changed to a high-temperature specification, and our heat-resistant submersible pump model JCVH was incorporated into the raw water pump. The user's wastewater is discharged in batches, and depending on the situation, it can be either acidic or alkaline. Therefore, we implemented control on both sides to accommodate either condition for neutralization. A vertical mixer for dilution stirring was installed in the sulfuric acid tank. The shaft and impeller were processed with FRP lining for sulfuric acid resistance. We adopted our electromagnetic pump for both sulfuric acid and caustic soda injection pumps.

The client was a university in the Chubu region, and they requested treatment for wastewater resulting from experiments related to cement and concrete. Since they were looking for a compact and simple device, we designed it to complete the neutralization in a single tank. Because we were able to hold meetings before the new construction work began, the foundation (concrete) was prepared perfectly, and the handover of operations from the design company went smoothly. Our company has a system in place that allows for appropriate proposals and the realization of our customers' "wants" through collaboration between sales and design. Please feel free to contact us when you need our services. *For more details, please refer to the PDF materials or feel free to contact us.

We received a message from a major food factory in Kansai stating that they are "looking for a neutralization device for CIP wastewater discharged from a newly established factory." Due to the complexity of the control, we proposed using a sequencer (touch panel). They appreciated that we could handle the entire construction, leading to our adoption. If neutralization does not occur for any reason, they cannot stop the equipment line. Therefore, considering all possibilities, we designed a flow that returns to the raw water tank if the average value of the two electrodes installed in the discharge tank is NG. Additionally, during the construction phase, we held discussions from the foundation design stage and worked with the user on the buried pipes from the raw water tank (concrete pit). The person in charge evaluated us by saying, "It was great to have a sales representative with technical skills whom we could entrust everything to." [Case Study] ■ Delivery: Major food company in Kansai ■ Application: pH neutralization treatment of CIP cleaning wastewater *For more details, please refer to the PDF document or feel free to contact us.

We received a contact from a design company in the Kanto region and would like to introduce a case where we delivered an "automatic pH neutralization device" to Kanto Gastroenterology Clinic.

We received an inquiry from Company F, a steelworks in Saga Prefecture, after they viewed our website, stating that "the scale of acid washing has increased, and we would like to automatically neutralize the wash water from the subsequent process." Upon discussing their needs, we learned that currently, after acid washing, they are washing with water near a drainage ditch, which is very inefficient. They expressed a desire to create a pit for washing and to place a neutralization device within that pit. Therefore, we proposed a collection pit and pit size to allow for washing after acid treatment within the pit and to pump the water directly to the neutralization device. Additionally, since the wastewater before neutralization is acidic and would corrode a standard submersible pump, they opted for a corrosion-resistant submersible pump (with automatic control). [Case Details] ■ Delivery: Saga Prefecture Steelworks ■ Application: Automatic pH neutralization treatment of acid wash wastewater ■ Specifications: Acid control at one point, 400L/Day *For more details, please refer to the PDF document or feel free to contact us.

We received an inquiry from a certain pharmaceutical factory in Saitama Prefecture stating, "We are looking for a good manufacturer because other companies' pure water systems are expensive." Since this project also utilizes a subsidy from Tokyo, there were concerns about the rigor of the documentation. However, we were awarded the contract due to our evaluation on cost, responsiveness, and the fact that we can handle the installation work in-house. H2 was recognized for its flexibility in adapting the system configuration to the client's specifications, and since we can also carry out the installation work ourselves, we have received many positive comments from customers regarding the simplification of arrangements and peace of mind.

We received a request from the North Kanto Parts Factory to develop a device that circulates high-temperature corrosive liquids and inspects the internal corrosion of products connected during the process. The control system requires a heating function (to stop and maintain at a specified temperature), liquid level control, and the ability to set up cycle operation (such as an 8-hour cycle count). We proposed and were accepted to provide a compact device that incorporates these features into a cart. Devices that require corrosion resistance and heat resistance, like this one, are our specialty. Please feel free to consult us. [Overview] ■ Delivery: North Kanto Parts Factory ■ Purpose: Device for investigating internal corrosion of product prototypes ■ Request: Development of a circulation device to examine the corrosion resistance of products *For more details, please refer to the PDF document or feel free to contact us.

The size of the urea raw material is almost uniform for each particle, but it can clump together due to moisture, leading to various forms of lumps during transportation. Therefore, we proposed the use of a conveyor belt for transportation. After evaluating the costs, delivery times, and responsiveness, our proposal was accepted. The equipment is basically automatic, and after attaching the FIBC (Flexible Intermediate Bulk Container), it starts the division of 1000 kg (which can be changed as needed) simply by turning on the power. However, to eliminate the need for operators to manipulate controls in front of the control panel, we also added a remote control for ON/OFF functionality. 【Case Overview】 ■ Consultation Content: We want to divide urea (powder) into FIBCs. ■ Proposal - Transportation via conveyor belt - Added remote control for ON/OFF to eliminate the need for operators to manipulate controls in front of the control panel - Considered safety by placing emergency stop buttons in various locations on the equipment - Ensured that emergency stops can also be activated via the remote control *For more details, please refer to the PDF document or feel free to contact us.

Even for custom products (PVC processed items), H2 quickly and affordably designs and manufactures high-quality products! We processed slits to allow for the insertion and fixation of aluminum plates inside the tank, rather than just a simple storage tank. The material of the tank is the most important selection point for corrosion resistance, but in this case, a proposal using PVC (or PVDF) is better due to its high processing flexibility. To fit into the limited space, we repeatedly discussed the shape and size before receiving the order. Customers who have been turned away by other companies or are not satisfied with the price or service are welcome to consult with us!
