Material Processing

In the field of material processing, Jielvfilter provides one-stop air filtration solutions for the pulp and paper industry, metal processing industry, and wastewater treatment industry.


Pulp & Paper:


Gaseous pollutants from pulp and waste paper bleaching, lignin removal and wastewater treatment include: hydrogen sulfide, sulfur dioxide, mercaptans, chlorine, chlorine oxide, ozone. These gaseous pollutants can cause damage to surrounding electronic and electrical equipment, especially in places where critical equipment and precision instruments are installed. For example, the safe operation of electronic equipment, control rooms, process control systems and compressors create risks. Corrosion of copper and silver-plated components can reduce process efficiency, increase maintenance costs and expensive repairs, and even cause downtime losses.

For the special requirements of the pulp and paper industry, Jielv develop customized chemical filtration solutions for you to ensure effective and permanent removal of corrosive polluting gases.




Metalworking industries include aerospace, polishing, grinding, laser cutting, plasma cutting, machining, painting, shot peening, silos, welding, thermal spraying, etc.

Contamination from metalworking incudes heavy dust, explosive dust, and molecular contaminants that cause odor, corrosion, and toxic threats to operators and the environment. If fumes from metalworking processes such as welding are not properly managed, electronic controls can fail, halting operations and requiring emergency repairs. This results in production downtime and lost productivity.

All of these require unique air filtration solutions that provide high levels of long-term performance under potentially harsh operating conditions.

Jielv focuses on industrial dust and fume filtration, preventing pollutants from entering the work space and outside air, thereby creating a safer and cleaner environment.


Waste water treatment:


Growing global population and global warming are placing extreme demands on clean water supplies. Waste water treatment plants are critical infrastructure assets in the world. Severe odor issues are a common problem in most wastewater treatment plants, and they can have a huge impact on the health of plant personnel and the safety of treatment system equipment.

A complex gas mixture generates odor, like hydrogen sulfide and mercaptans, foul air also contains other organic sulfur, ammonia (NH3), and organic nitrogen gases.

The outer shell helps suppress odors, but the enclosure can lead to the accumulation of methane. Methane is an odorless but explosive gas. Therefore, enclosed spaces must be ventilated to keep methane concentrations at safe levels.

The release of acid gases is also a problem in wastewater treatment facilities. If these gases are left uncontrolled in the supply air of the control room, they will damage the electrical gears used to regulate complex process equipment such as pumps and pressure piping.

Jielv offer filtration solution to gas-related problems in wastewater treatment plants. Eliminate safety hazards that endanger human health and reduce equipment damage, maintenance and downtime.
