Precision Filter
The precision filter uses microporous filter cartridges or membranes as the filtration medium to finely remove tiny particles, suspended solids, colloids and some microorganisms from water. With high filtration precision, stable effluent quality and easy operation and maintenance, it is widely used in reverse osmosis pretreatment, circulating water treatment, advanced drinking water treatment, and precision liquid filtration in the chemical and pharmaceutical industries.
The precision filter, also known as a security filter or microporous filter, is a fine filtration device with microporous filter cartridges as the core filtration element. It is used to remove tiny particles, suspended solids and colloids from water, and is an essential pre-protection device for membrane treatment systems such as reverse osmosis.
Working principle: under pressure, the raw water passes through the microporous filter cartridges, where tiny particles and suspended solids are retained by the cartridges, and the purified water is discharged through the outlet. As the operating time extends, the differential pressure across the cartridges increases; when it reaches the set value, the cartridges are replaced to restore filtration performance.
The equipment offers high filtration precision, and cartridges of different pore sizes can be selected according to water quality requirements. The cartridges use PP melt-blown, pleated cartridges or filter membranes, providing strong dirt-holding capacity and long service life. The housing is made of stainless steel and is corrosion-resistant. The structure is simple, easy to maintain, and cartridges can be replaced quickly.
It is widely used in reverse osmosis pretreatment, circulating water treatment, advanced drinking water treatment, electronic ultrapure water production, and precision liquid filtration in industries such as chemical, pharmaceutical and food.

Inclined Screen Filter
The inclined screen filter (also called curved screen or inclined screen) uses wedge-shaped screen bars to form a curved screening surface, separating suspended solids from wastewater by gravity. With a simple structure, no moving parts, maintenance-free operation and low running cost, it effectively removes solid suspended matter from wastewater. It is widely used for pretreatment and solid-liquid separation in livestock wastewater, slaughterhouse wastewater and food processing wastewater.
Sand-Water Separator
The sand-water separator separates sand and other inorganic particles from wastewater through screw conveying and gravity settling. It is commonly used with grit chambers in wastewater treatment plants to prevent sand from wearing down downstream equipment.
