The Manual Bar Screen is a simple, robust, and cost-effective primary screening solution used for removing large floating solids and debris from wastewater channels. Designed for small to medium-flow installations, this fixed bar screen is installed at an inclined angle within the channel and is manually raked at regular intervals. With no mechanical components and minimal maintenance requirement, it provides an economical screening option for sewage treatment plants, pumping stations, and stormwater drainage systems.
Wastewater flows through the inclined bars of the screen, where large solids, rags, plastics, and debris are trapped on the upstream face. As screenings accumulate, the operator manually cleans the bars using a rake or hook. The captured material is then removed and disposed of at designated points. This manual cleaning mechanism ensures uninterrupted flow while preventing clogging of downstream units such as pumps and treatment processes.

The Box-Type Lifting Screen is a robust, heavy-duty screening solution designed for wastewater channels with high solid loads. Featuring a box-shaped perforated bucket, this screen efficiently captures and lifts large volumes of solids from the flow. Constructed from high-quality stainless steel and equipped with manual lifting mechanisms, it is suitable for large municipal STPs, sewage pumping stations, and industrial effluent channels. Its sturdy design ensures long-term reliability, even under challenging conditions.
Wastewater passes through vertical bars where large solids and debris are retained. These solids are collected in the box-shaped perforated bucket at the base of the screen. Operators lift the screen using a manual winch or chain pulley system, raising the bucket along with the trapped solids. Once lifted above the channel, the perforations allow excess water to drain while retaining solids, which are then emptied at a designated disposal point. This intermittent lifting method ensures efficient debris removal, prevents clogging, and protects downstream equipment.

The J-Type Lifting Screen is a manually operated screening system designed for medium-flow wastewater channels where mechanical or automated screens are not required. Its unique J-shaped bucket arrangement allows effective collection, lifting, and removal of screenings from the channel. Built with stainless-steel construction and guided through brass bushes and steel rollers, this lifting screen offers a reliable, low-maintenance, and cost-effective solution for municipal STPs, sewage pumping stations, and industrial effluent treatment plants.
Wastewater flows through the vertical bars of the screen, where floating and suspended debris is retained. The accumulated screenings gradually settle in the J-shaped bucket installed at the lower section of the screen.
At desired intervals, operators lift the screen using a chain pulley block or manual winch system. As the screen assembly rises, the J-bucket collects and carries the trapped solids above the channel. The screenings are then manually emptied at a designated disposal area.
This lifting mechanism ensures efficient cleaning, minimal manual contact with debris, and smooth screen operation even under varying flow conditions.

The Apollo Parabolic Screen is a high-efficiency fine screening solution designed for wastewater and industrial effluent applications that require precise solid-liquid separation. Ideal for low-flow conditions, it can remove up to 90% of suspended solids. Constructed from durable SS-304 / SS-316L, it features non-submerged moving parts and a wedge wire screen for long-term reliability, minimal maintenance, and consistent high performance.
It is suitable for small STPs, industrial effluent systems, food and dairy processing plants, chemical industries, and other processes demanding fine filtration.
Wastewater or effluent enters the parabolic screen, flowing across a welded wedge wire surface. Suspended solids larger than the slot size (as fine as 0.5 mm) are captured on the screen surface. The parabolic shape ensures uniform flow distribution, reducing turbulence and low-velocity zones, which improves screening efficiency. Non-submerged moving parts prevent corrosion and erosion, while the captured solids slide downward or are easily removed during maintenance.
This design ensures high solids removal efficiency without interrupting flow, even under low-flow conditions.

The Manual Bar Screen is a simple, robust, and cost-effective primary screening solution used for removing large floating solids and debris from wastewater channels. Designed for small to medium-flow installations, this fixed bar screen is installed at an inclined angle within the channel and is manually raked at regular intervals. With no mechanical components and minimal maintenance requirement, it provides an economical screening option for sewage treatment plants, pumping stations, and stormwater drainage systems.
Wastewater flows through the inclined bars of the screen, where large solids, rags, plastics, and debris are trapped on the upstream face. As screenings accumulate, the operator manually cleans the bars using a rake or hook. The captured material is then removed and disposed of at designated points. This manual cleaning mechanism ensures uninterrupted flow while preventing clogging of downstream units such as pumps and treatment processes.

The Box-Type Lifting Screen is a robust, heavy-duty screening solution designed for wastewater channels with high solid loads. Featuring a box-shaped perforated bucket, this screen efficiently captures and lifts large volumes of solids from the flow. Constructed from high-quality stainless steel and equipped with manual lifting mechanisms, it is suitable for large municipal STPs, sewage pumping stations, and industrial effluent channels. Its sturdy design ensures long-term reliability, even under challenging conditions.
Wastewater passes through vertical bars where large solids and debris are retained. These solids are collected in the box-shaped perforated bucket at the base of the screen. Operators lift the screen using a manual winch or chain pulley system, raising the bucket along with the trapped solids. Once lifted above the channel, the perforations allow excess water to drain while retaining solids, which are then emptied at a designated disposal point. This intermittent lifting method ensures efficient debris removal, prevents clogging, and protects downstream equipment.

The J-Type Lifting Screen is a manually operated screening system designed for medium-flow wastewater channels where mechanical or automated screens are not required. Its unique J-shaped bucket arrangement allows effective collection, lifting, and removal of screenings from the channel. Built with stainless-steel construction and guided through brass bushes and steel rollers, this lifting screen offers a reliable, low-maintenance, and cost-effective solution for municipal STPs, sewage pumping stations, and industrial effluent treatment plants.
Wastewater flows through the vertical bars of the screen, where floating and suspended debris is retained. The accumulated screenings gradually settle in the J-shaped bucket installed at the lower section of the screen.
At desired intervals, operators lift the screen using a chain pulley block or manual winch system. As the screen assembly rises, the J-bucket collects and carries the trapped solids above the channel. The screenings are then manually emptied at a designated disposal area.
This lifting mechanism ensures efficient cleaning, minimal manual contact with debris, and smooth screen operation even under varying flow conditions.

The Apollo Parabolic Screen is a high-efficiency fine screening solution designed for wastewater and industrial effluent applications that require precise solid-liquid separation. Ideal for low-flow conditions, it can remove up to 90% of suspended solids. Constructed from durable SS-304 / SS-316L, it features non-submerged moving parts and a wedge wire screen for long-term reliability, minimal maintenance, and consistent high performance.
It is suitable for small STPs, industrial effluent systems, food and dairy processing plants, chemical industries, and other processes demanding fine filtration.
Wastewater or effluent enters the parabolic screen, flowing across a welded wedge wire surface. Suspended solids larger than the slot size (as fine as 0.5 mm) are captured on the screen surface. The parabolic shape ensures uniform flow distribution, reducing turbulence and low-velocity zones, which improves screening efficiency. Non-submerged moving parts prevent corrosion and erosion, while the captured solids slide downward or are easily removed during maintenance.
This design ensures high solids removal efficiency without interrupting flow, even under low-flow conditions.
