FOOMA JAPAN 2024

By changing the wastewater treatment, both costs and CO2 emissions can be reduced. "Tokutoku-bububu" enables methane fermentation treatment of food wastewater.

Methane fermentation wastewater treatment is a method of wastewater treatment that utilizes microorganisms (anaerobic bacteria) that thrive in environments with little to no oxygen. Since aeration, which supplies air to the treatment tank, is unnecessary, it can significantly reduce power consumption. Additionally, this process converts the pollutants (organic matter) in the wastewater into methane gas. The generated methane gas has the same components as city gas, and by using it as fuel for boilers and generators, it can reduce the use of conventional fuels (fossil fuels). Furthermore, due to the slow growth of microorganisms, the amount of excess sludge generated is also low, allowing for simultaneous waste reduction. These features not only reduce the running costs associated with wastewater treatment but also contribute to CO2 reduction. The reduction of fuel corresponds to Scope 1, the reduction of electricity corresponds to Scope 2, and the reduction of waste corresponds to Scope 3, making it a technology that is rapidly spreading as a means of achieving decarbonization in factories. We will be exhibiting at the 5th Food Tech Japan Tokyo (to be held from November 20 to 22, 2024, at Makuhari Messe) at booth 2 Hall 7-54. We will also be showcasing this product, so please come visit us.

• Water Treatment

A wastewater treatment device that recovers methane gas from wastewater (creating energy), requires little power (saving energy), and generates a small amount of sludge. It realizes decarbonization.

In conventional wastewater biological treatment (such as the activated sludge method), treatment is carried out by utilizing oxygen supplied by blowers, allowing microorganisms to oxidatively decompose pollutants in water into water and carbon dioxide (aerobic treatment). In contrast, anaerobic treatment (methane fermentation) is a method that converts pollutants primarily into methane gas through the action of anaerobic (oxygen-unfriendly) microorganisms under oxygen-deprived conditions. It has been gaining attention recently due to the various advantages it offers that are not present in aerobic treatment. 【Features】 - Recovery of methane gas from wastewater, contributing to CO2 reduction with low energy consumption - Sludge generation is 1/5 to 1/10 of that in aerobic treatment - Sufficient water quality can be achieved with "UASB-TLP" alone in cases of sewage discharge - High-load operation with CODcr load of 40-50 kg/m³ per day is possible For more details, please contact us or download the catalog.

New installation/expansion, wastewater discharge/riverside discharge, usable in various situations regardless of industry! Aerobic wastewater treatment system using fixed bed carriers.

"Rotating Jiraiya" is a fixed bed (contact aeration type) wastewater treatment device. It fills the tank with a carrier that retains microorganisms, purifying the water quality through the activity of the microorganisms on the carrier's surface. There is no need to manage sludge concentration like in the activated sludge method, and there is no return sludge. Strict management of dissolved oxygen concentration is also unnecessary, allowing for stable operation without specialized knowledge. The high-performance carrier with a large surface area and continuous cleaning mechanism completely prevents the major drawback of fixed beds, which is tank clogging, enabling high-load operation of 5 to 15 kg-BOD/m³·D. 【Features】 ○ Capacity enhancement of existing facilities ○ Reduction of running costs ○ Easy operation management For more details, please contact us or download the catalog.

• Sanitary fixtures

Excellent coagulation and dewatering performance! This polymer coagulant achieves sufficient effects with a small amount of addition.

The polymer coagulant "Denha Floc" forms a strong floc with good solid-liquid separation properties. The coagulation treatment results in high clarity treated water, and during sludge dewatering, there is minimal leakage and rapid dewatering is possible. We offer various grades with different compositions and polymerization degrees, properties (powder/liquid), and packaging (paper bags/QB cans/1-ton containers) to meet our customers' needs. 【Features】 ○ Excellent coagulation and dewatering performance ○ Cost reduction ○ Diverse product range → Anionic, cationic, amphoteric, as well as powder/liquid types For more details, please contact us or download the catalog.

The carryover of SS is low, and good quality treated water can be obtained.

The solid-liquid separation of the "Super Pressurized Floating Device SUPER-DAF" utilizes a technology that attaches fine bubbles to particles in water, allowing for their flotation and removal. It is widely used alongside sedimentation methods for the removal of suspended solids (SS). The rapid separation speed of particles results in a compact device, and the high concentration of the resulting sludge makes subsequent treatments such as dewatering easier. 【Features】 ○ Achieves over 20 times the solid-liquid separation speed compared to sedimentation methods ○ The device is extremely compact ○ Extremely low outflow of SS ○ Produces high-quality treated water For more details, please contact us or download the catalog.

Automate the troublesome dissolution process! Prevents clogging and continuously supplies a solution of constant concentration.

The polymer automatic dissolution device APD-200/500/1000 is a machine that automatically performs the tasks of supplying and dissolving polymers. By simply replenishing the hopper with polymers, it can continuously supply a solution with a constant concentration. The adoption of an eco-blow type table feeder allows for the diffusion supply of polymers, preventing the occurrence of "mamakos." 【Features】 ■ Easy operation ■ Constant concentration → The supply amounts of polymer and water can be accurately controlled → It is possible to continuously create a solution with a constant concentration ■ No occurrence of "mamakos" ■ Various specifications → The dissolution tank can be selected from PVC, FRP, or SUS For more details, please contact us or download the catalog.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.
