JCL Series Water Purifier | Inclined Tube Sedimentation Unit | Quartz Sand Filtration Purifier

Working Principle Raw water is pumped into the unit, where coagulant is dosed and rapidly mixed in the mixing zone. It then enters the flocculation zone, where slow stirring causes fine flocs to agglomerate into larger particles. The flocs move into the inclined tube settling zone, where the tube media accelerates settling and sludge collects in the bottom hopper. Clarified water enters the filtration chamber, passing through a quartz sand bed that intercepts remaining suspended solids. Clean water collects in the top clear water tank or discharges directly. When the filter bed clogs or a set time interval is reached, backwash starts. Backwash water flows upward through the quartz sand bed, flushing trapped solids out of the vessel. Normal filtration resumes once backwash completes. Sludge in the hopper discharges periodically through the sludge valve. An automatic control system is available for fully automated dosing, backwash, and sludge discharge. Application Fields 1.Rural & Township Water Supply: River, lake, and reservoir water purification — the core treatment unit for small water plants 2.Industrial & Mining Water Supply: Process and potable water treatment for factories 3.Boiler & Industrial Water Pretreatment: Pre-treatment for boiler makeup water and circulating water systems 4.Water Reuse: Advanced treatment of wastewater plant effluent for irrigation, washdown, or industrial cooling FAQ Q1: What kind of raw water can the JCL Series Water Purifier handle? A: It's designed for surface water — rivers, lakes, reservoirs, and ponds — with inlet turbidity typically up to 3,000 mg/L. Outlet turbidity stays consistently below 3–5 mg/L, meeting drinking water standards or industrial water quality requirements. If raw water turbidity consistently exceeds 3,000 mg/L, a pre-settling tank is recommended. Lower-turbidity sources like groundwater also work, though the flocculation and dosing stage typically isn't needed. Q2: What's the difference between the JCL Series Water Purifier and the FA Series Integrated Water Purifier? A: Both are integrated treatment units with the same core process. The main differences are structural configuration and applicable scale. The FA type uses siphon backwash — no backwash pump needed — suited for small to medium capacities. The JCL type typically uses a pressure vessel or gravity structure, with more flexible configuration and customizable capacity and layout, covering a wider range of applications. Selection depends on raw water quality, flow rate, and site conditions. Q3: What are the main components of the JCL Series Water Purifier? A: Main components include the mixing reaction zone, flocculation zone, inclined tube settling zone, filtration chamber, clear water chamber, and sludge hopper. The mixing zone has an agitator for rapid chemical contact; the flocculation zone uses slow stirring to promote floc formation; the settling zone is packed with inclined tube media for higher settling efficiency; the filtration chamber contains quartz sand media to intercept residual solids; the sludge hopper collects settled sludge, discharged periodically through a sludge valve. External connections include inlet, outlet, backwash water, and sludge piping with valves, with an optional fully automatic control system.
