Unique Features of Fine Arc

Fine Arc is a wedge wire screen for classification, solid-liquid separation, and dewatering. It is suitable for worksites that need to capture contaminants from wastewater or filter water in production processes before entering the main treatment system.

• Wastewater treatment and reduced load on the main system: It performs primary filtration to capture contaminants, sludge, or suspended solids (SS), helping reduce the load and improve the efficiency of the next-stage wastewater treatment system.
• Turning waste into resource recovery: It is effective in capturing particles for reuse, such as recovering resin powder in the chemical industry, recovering rice bran in the food industry, or filtering cotton residues in the textile industry.
• Wide applicability across nearly all industries: It can be applied broadly and flexibly in the food, beverage, chemical, textile, environmental, wood, energy-related applications such as algae filtration, and livestock industries.
• Supports energy saving: It can be applied in filtration processes to circulate and reuse washing water within factories.
• Real testing before decision-making: Actual water samples from the worksite can be tested at the UCHIMURA Test Center (UTC) to simulate results and select the most suitable treatment method.

Wedge Wire Screen Technology

Fine Arc belongs to the group of screens that use the concept of Wedge Wire Screen, which is a screen for separation and classification. It uses gaps or slits created by arranging inverted triangular wedge-shaped wires on support rods at specified intervals.

The wedge wire structure has key advantages: it is difficult to clog, provides good drainage, and supports backwash cleaning to assist with cleaning. In addition, it is strong, durable, and can be processed into various shapes according to the application, making it suitable for work that requires continuity in filtration and separation processes.

Applications in the Food and Textile Industries

In the textile industry, Fine Arc is suitable for removing small fibers and collecting cotton residues from wastewater or liquids in production processes. In the food industry, it can be used for recovering rice bran from wastewater in pickled vegetable production and recovering agglomerated rice bran sludge.

There are also application examples in the beverage industry, such as removing solid impurities and managing highly concentrated wastewater. Environmental applications include removing suspended solids (SS) from discharged rainwater or removing green algae from ponds or waterways.

Guidelines for Selecting a Screen Suitable for Water Samples

Selecting Fine Arc should be based on the characteristics of the water sample, the type of solids to be separated, fiber or particle size, the amount of suspended solids, and the goal of the process. Examples include primary wastewater treatment, fiber capture, sludge reduction, or solid separation before entering the main treatment system.

For worksites that are not yet sure which type of screen should be used, Fine Arc can be considered together with water treatment products such as Ultra TN Screen, Fine Arc, TS Drum Screen, and FineWedge in order to identify a suitable screen and treatment method based on each factory’s water sample.

Frequently Asked Questions (FAQ)

Q1: What type of work is Fine Arc suitable for?
A1: It is suitable for primary wastewater treatment, solid-liquid separation, and capturing fibers or contaminants before entering the main treatment system.

Q2: How can Fine Arc be used in the textile industry?
A2: It can be considered for removing small fibers and collecting cotton residues mixed with water in production processes.

Q3: Can Fine Arc be used in the food industry?
A3: It can be considered for applications that require sludge separation or raw material recovery from wastewater, such as work related to rice bran or sludge from production processes.

Q4: What information should be prepared before making an inquiry?
A4: A water sample, the characteristics of the solids to be separated, fiber or particle size, water volume, and treatment goals should be prepared in order to select a screen suitable for the actual worksite.
