Principle of inclined tube sedimentators: The sedimentation and water purification method using inclined tubes and plates involves placing these elements above the suspended sludge layer, at an inclination angle of 60 degrees. This allows the suspended particles in the raw water to accumulate on the lower surface area of the inclined tubes and plates, forming a thin layer of sludge. Under the effect of gravity, this sludge then slides back into the suspended sludge layer and eventually settles into the sludge collection container. It is then discharged through the sludge pipe into the sludge tank for treatment or comprehensive utilization. The clean water at the top gradually rises to the collection pipe for discharge; it can be discharged directly or reused. Settling tank: A structure that uses gravity to settle and remove suspended solids from water. Inclined tube: A sedimentation device developed theoretically for shallow tanks, widely used in water treatment sedimentation tanks. Inclined tubes are primarily used for sand removal at the inlets of water supply and drainage systems, for the sedimentation of industrial and domestic water, for sewage sedimentation, oil separation, and tailing concentration. They can also be used in the renovation of existing tanks. It is the most widely used and mature water treatment device in current water supply and drainage projects. A honeycomb-shaped inclined tube with a length of 1 meter and a slope of 60 degrees, whose cross-section is generally hexagonal, assembled from wavy sheets. The material is an engineering material such as EP copolymer or polypropylene. 　　 Main features: 1. Large wet perimeter, small hydraulic radius. 　　 2. The laminar flow condition is good, and particle sedimentation is not disturbed by turbulent flow. 　　 3. When the length of the inclined tube is 1 meter, the effective load is designed at 3–5 tons/m²·hour. When VO is controlled within the range of 2.5–3.0 mm/s, the quality of the effluent water is optimal. 　　 4. Fiberglass honeycomb inclined tubes are used at the water intake; when the tube length is 2–3.0 meters, they can operate safely in high-turbidity conditions with a sediment content of 50–100 kilograms per cubic meter. 　　 5. The treatment capacity of inclined tube sedimentation tanks is 3–5 times that of horizontal flow sedimentation tanks, and 2 times that of accelerated clarifiers and pulse clarifiers. They are the most widely used and mature water treatment devices in water treatment projects. Advantages of inclined tube and inclined plate sedimentation: 1. Simple structure, no vulnerable parts, long service life, and reduced maintenance needs. 2. Stable operation and easy to use. 3. Low power consumption and energy savings. 4. It requires less land, has lower investment costs, can be put into operation quickly, and offers high efficiency. Uses of inclined tube and inclined plate sedimentation tanks: Inclined tube and inclined plate sedimentation tanks can serve as auxiliary system equipment for water treatment processes such as air flotation and coagulation methods, and they can be used to treat various types of wastewater. 1. Electroplating wastewater is a type of mixed-metal wastewater; the removal rates for chromium, copper, iron, zinc, and nickel can exceed 93%, and after treatment in inclined tube or inclined plate sedimentation tanks, it meets the discharge standards. 2. In coal mines, wastewater can reduce its turbidity from 600–1600 mg/L to 5 mg/L. 3. For industrial wastewater from industries such as printing and dyeing, the color removal rate is 70-90%, while the COD removal rate is 50-70%. 4. For wastewater from industries such as leather and food processing, the removal rate of COD can reach 60–80%, while the removal rate of solid impurities is over 95%. 5. The COD removal rate for chemical wastewater is 60-70%, the color removal rate is 60-90%, and the suspended solids levels can meet the discharge standards

Mm-hmm! Thanks, big guy! ! As a beginner, I’m truly grateful! ! Thank you again~ haha
