Affordable 7000 LPH RO Water Purifier for Industrial Use

1. Understanding the “7000 LPH RO Plant”

What does “7000 LPH RO” mean?

• LPH = Liters per Hour — a 7000 LPH RO plant is designed to purify around 7,000 liters of water every hour under optimal operating conditions.

• This is a very high-capacity RO system, clearly in the industrial/commercial class, not a typical home water purifier.

• Use-cases: large-scale industries, institutional buildings (hotels, colleges, hospitals), water-dispensing ATMs or kiosks, bottled water plants, or community-level purification setups.

Why choose a 7000 LPH system?

• To meet very high water demand reliably.

• To have a centralized purification system rather than multiple smaller purifiers.

• To scale purified water supply for commercial operations or business models (e.g., water ATMs).

• To handle process-oriented water needs in manufacturing, where RO-pure water is required.

2. Core Components of a 7000 LPH RO Plant & Role of the RO Tap Connector

To build or run a 7000 LPH RO Plant, here are the major subsystems — and why the RO Tap Connector (the final water outlet fitting) is critical.

2.1 Key Subsystems

1. Pre-Filtration

   • Sediment / Multimedia Filter: Removes large particles, grit, sand.

   • Activated Carbon Filter: Filters out chlorine, organics, and helps protect RO membranes.

   • Cartridge / Micron Filter: Provides fine filtration before feed enters the RO membranes.

2. High-Pressure Pump

   • Drives the feed water into RO membranes at high pressure. For 7000 LPH, the pump must be capable and robust.

3. RO Membranes

   • Usually Thin-Film Composite (TFC) industrial-grade membranes.

   • Responsible for rejecting salts, dissolved solids (TDS), heavy metals, and other contaminants.

4. Antiscalant / Dosing System

   • To prevent scaling on RO membranes, many plants include a dosing pump that injects antiscalant or other chemicals.

5. Post-Treatment

   • TDS Controller / Remineralizer: Adds back healthy minerals or controls the final TDS.

   • UV / UF Module (Optional): For microbial disinfection or final polishing.

6. Automation & Control

   • Float switches/level sensors to auto shut-off when tanks are full.

   • Control panel: pump on/off, alarms, system status.

   • Pressure gauges for feed, reject, and permeate lines.

7. Skid / Frame

   • Built from Stainless Steel (SS) or FRP (Fiber Reinforced Plastic) depending on design and budget.

8. Electrical System

   • Power supply for pump, control panel, dosing, sensors.

   • Likely industrial power (three-phase) in many setups.

9. RO Tap & RO Tap Connector

   • RO Tap: The faucet / output point where purified water is drawn.

   • RO Tap Connector: The plumbing fitting that joins the purified water (permeate) line to the tap or the distribution system.

   • Importance: Given the high flow (7,000 LPH capacity), the connector must handle high pressure, be food-grade, and be extremely reliable — otherwise, you can have leaks, restrictions, or failures at the outlet.
