SQ Fully Automatic Filter

I. Overview
"Filtration" is an indispensable technical process in modern water treatment. The SQ fully automatic filtration unit pioneers a new trend in domestic filtration technology. From water intake, filtration, output, backwashing to sewage discharge, all operations are driven by hydraulic action, achieving full automation without the need for specialized operator management. Consequently, it will completely replace the various types of filtration equipment developed over decades in China for water treatment, offering significant advantages such as water savings, electricity conservation, reduced labor, compact footprint, and minimal sewage discharge. The invention of this unit represents a major breakthrough in China's water treatment filtration technology and plays a positive role in alleviating the country's water scarcity. It provides a reliable module for industrial and mining enterprises to achieve automated management. The timely adoption of this unit will bring substantial economic, social, and environmental benefits to the nation and enterprises.
II. Wide Range of Applications
The SQ series fully automatic filtration units are primarily used to remove particulate impurities, suspended solids, and substances that form adsorption precipitates in water, providing industrial and domestic water that meets various usage requirements.
(1) Used as purification filtration units for producing tap water in urban, rural, industrial, and mining settings.
(2) Employed as side-stream filtration units for circulating water in production processes such as petroleum, chemical, metallurgical, power, textile, pharmaceutical, light industry, and machinery sectors.
(3) Utilized in purification processes for water features and swimming pools in high-end hotels, villas, restaurants, and shopping malls.
(4) Applied as pretreatment units for boiler softened water and high-purity water systems in the power industry.
(5) Used in water supply treatment units for the food, industrial, and beverage industries.
(6) Employed in intermediate water reuse and purification filtration units during wastewater treatment processes.
III. Advanced Technical Performance
The SQ fully automatic filtration unit is a non-electrically controlled filtration device, operating entirely through the gravitational pressure of pre-filtered water and mechanical principles to achieve full automation.
The SQ fully automatic filtration unit is divided into two types: gravity type and pressure type. The following design parameters pertain to the gravity type. Detailed diagrams for the pressure type will be provided separately upon adoption.
No external backwash water pumps or water towers are required. Water intake, output, backwashing, and sewage discharge do not necessitate operational valves or corresponding electrical control facilities, thereby saving on pump house construction and extensive electrical control instruments and equipment. Specialized operator management is unnecessary, and operating costs are low.
1. Saves raw water with high output; water utilization rate ≥97%.
2. No backwashing facilities are required, and the working head is low (0.06MPa), resulting in over 20% energy savings compared to other domestic filters.
3. Simple structure with no need for additional supporting facilities, saving on piping materials and civil foundation. Compact size allows installation indoors or outdoors without special factory requirements, thus reducing capital investment, auxiliary facilities, and installation costs.
4. Main components are national standard parts; the body material is carbon steel, and working parts are made of stainless steel and copper.
5. Output water quality ranges between 0.5-10 NTU, adjustable according to user needs.
