01 / Mechanical Screen
YINI rake bar screens are engineered for municipal pumping-station inlets, where dependable screening is essential to protect pumps and downstream treatment equipment. The screen captures rags, plastics, wipes, leaves, and other bulky debris before it reaches the pump sump.
Designed for deep channels and demanding solids loads, each unit can be tailored to the civil layout, flow conditions, bar spacing, discharge arrangement, and control philosophy of the project.
Rake bar screens are particularly suited to pumping-station pre-treatment, helping prevent clogging, reduce pump wear, and keep wet-well operations stable. They can be installed at the headworks of municipal sewage pumping stations, combined sewer pumping stations, stormwater pumping stations, and wastewater treatment plant inlets.
Custom capacity: Screening widths can be manufactured up to 3 m, with channel depths up to 15 m to accommodate deep pump-station structures and high-flow inlet channels.
02 / Mechanical Screen
YINI internal feed screens provide efficient solid-liquid separation for municipal and industrial wastewater treatment. Wastewater flows into the screen body, where the screening surface retains floating, fibrous, and suspended debris while screened water passes through to the downstream process.
The enclosed, compact configuration combines screening and controlled solids discharge in one unit, making it well suited to inlet works, pre-treatment upgrades, and projects where installation space is limited.
Internal feed screens are widely used for preliminary treatment at municipal wastewater treatment plants, package treatment systems, industrial wastewater facilities, food-processing sites, and water-reuse projects. They help reduce the solids load on downstream pumps, sedimentation equipment, biological treatment, and sludge-handling systems.
Flexible integration: Screen aperture, treatment capacity, construction material, inlet and outlet orientation, and discharge arrangement can be configured to suit the required process and available layout.
03 / Mechanical Screen
YINI rotary perforated plate screens provide dependable fine screening for municipal and industrial wastewater treatment. Their continuously moving perforated screening panels capture small solids, fibers, hair, and floating debris while maintaining a steady flow through the inlet channel.
The rotating screen surface carries retained material upward for discharge, reducing manual cleaning requirements and helping maintain stable hydraulic performance in pre-treatment processes.
Rotary perforated plate screens are suitable for municipal wastewater treatment plant inlets, pumping-station pre-treatment, combined sewer overflow facilities, industrial wastewater plants, and water-reuse systems. They provide fine screening ahead of grit removal, biological treatment, membrane processes, and other downstream equipment.
Flexible configuration: Perforation size, screen width, treatment capacity, material selection, discharge arrangement, and control mode can be configured to match the wastewater characteristics and process requirements.
04 / Mechanical Screen
YINI rotary drum screens provide efficient fine screening for municipal and industrial wastewater. Wastewater flows into the rotating drum, where the perforated or wedge-wire screening surface retains fibers, hair, plastics, and other suspended solids while screened water passes through.
As the drum rotates, retained material is lifted out of the water and directed to the discharge zone. This continuous screening action supports stable treatment performance and reduces the solids load on downstream processes.
Rotary drum screens are used at municipal wastewater treatment plant inlets, pumping stations, water-reuse projects, industrial wastewater systems, and food-processing facilities. They are particularly effective where continuous removal of fine and fibrous solids is required before biological treatment, membrane filtration, or tertiary processes.
Adaptable configuration: Drum diameter, length, screen opening, material, inlet arrangement, discharge system, and control options can be configured for the required flow, solids load, and site layout.
05 / Fecal Sludge Treatment
YINI integrated fecal sludge treatment systems provide a compact receiving and pre-treatment solution for septage, toilet waste, and other high-solids slurry collected from decentralized sanitation systems. The integrated process can combine coarse screening, solids separation, grit removal, washing, dewatering, and conveying according to local disposal requirements.
By removing rags, plastics, sand, and other debris at the receiving stage, the system helps protect downstream pumps and treatment processes while improving the handling of collected sludge.
Suitable for fecal sludge receiving stations, municipal sanitation depots, wastewater treatment plants accepting septage, rural sanitation programs, and centralized treatment facilities. The equipment can be configured as a standalone pre-treatment package or integrated with subsequent liquid and sludge treatment stages.
Integrated configuration: Receiving hopper, screening, washing, separation, conveying, drainage connections, and odor-control interfaces can be arranged to suit the available site and treatment route.
