I. Equipment Overview
A microfiltration unit is a screen-based filtration device that traps fine suspended solids in water. It primarily consists of a drum-shaped metal frame with the drum rotating around a horizontal axis. The surface is covered with a stainless steel support mesh and a working mesh. In industrial wastewater treatment, problems such as clogging and filter damage are common, dragging down efficiency and increasing costs. Wuxi Sanshine Environmental Protection accurately identified these pain points and developed the internal flow microfiltration unit, using innovative technology to reconstruct the solid-liquid separation logic, providing a highly efficient and stable wastewater treatment solution.

II. Main Advantages
The main advantages of the Sanshine internal flow microfiltration unit are significant: First, it provides highly efficient and fine filtration. Utilizing advanced drum-type screen technology, the filtration accuracy is 0.5mm, effectively trapping fine particles, fibers, and other impurities. The suspended solids recovery rate exceeds 80%, resulting in more thorough separation and building a solid first line of defense for subsequent water treatment. Secondly, it boasts strong anti-clogging and damage resistance. Integrating advanced technology and operating conditions, it features an innovative filter structure and intelligent flushing system, optimizing water flow path and pore size distribution. Combined with high-pressure automatic flushing, it addresses clogging and damage issues at their source, improving operational stability and reducing downtime for maintenance.

Thirdly, its adaptable scenarios and performance characteristics are excellent. The Sanshine internal flow microfilter is universally adaptable, highly efficient, and economical. It can cover wastewater pretreatment in multiple water-intensive industries such as papermaking, leather making, and brewing, enabling wastewater recycling and reuse. It can also replace traditional mechanical bar screens, reducing upgrade costs. The Sanshine internal flow microfilter offers outstanding performance advantages: fully automatic operation requiring no supervision; stable effluent concentration facilitating sludge disposal; energy consumption reduced by over 30% at low speeds; compact structure and easy installation; durable materials ensure longevity; fewer vulnerable parts extend lifespan by 20%; and low maintenance costs. Two filter options are available to suit different filtration needs.

IV. Working Principle and Application Scenarios The Sanshine internal flow microfilter operates on a simple and controllable principle: wastewater is guided through a distributor to the inner wall of a rotating filter cartridge. Solid-liquid separation is achieved through the rotation of the cartridge and the shear force of the water flow, trapping impurities and allowing the filtrate to pass through the screen and be discharged. A built-in intelligent high-pressure washing system simultaneously cleans the filter screen to ensure unobstructed pores. The Sanshine internal flow microfilter has diverse applications, including industrial wastewater treatment, raw water filtration in waterworks, industrial water pretreatment, suspended solids recovery, and sewage treatment.
