Industrial RO
500 LPH to 200 m³/hr brackish & high-TDS systems with PLC automation and CIP.
This page opens with a scroll-driven 3D walkthrough of a 1,000 LPH industrial RO plant: raw water at 1,850 ppm passes through pre-treatment, a high-pressure pump and the RO membrane, leaving at roughly 40 ppm. Every station's details are written out in the cards below.
1,850 ppm in.40 ppm out.
An Excellent Water Industries 1,000 LPH commercial RO plant, as we build it. Feed: borewell, ~1,850 ppm TDS. Scroll to run the water through it — sand and carbon, through the membrane, to the tap.

STAGE 01 — PRE-TREATMENT
Sand, then carbon.
Two FRP vessels on top-mounted multiport valves: a multigrade sand bed drops turbidity, then activated carbon strips chlorine and organics. Antiscalant dosing protects the membrane downstream.
MediaSand 2×4 / 4×8
Carbon900 IV granular
STAGE 02 — HIGH-PRESSURE PUMP
Pressure against osmosis.
A vertical multistage stainless pump lifts the feed to working pressure after a 20-inch jumbo micron polish. Fully automatic, single-phase — the energy line of the plant.
Feed pressure~14–15 bar
Supply1-Φ 230 V
STAGE 03 — RO MEMBRANE
4040 spiral-wound.
Thin-film composite 4040 elements in a horizontal pressure tube reject dissolved salts down to ~40 ppm, handling feed up to 3,500 ppm. We’re going inside the element.
Permeate~40 ppm
Feed handledup to 3,500 ppm
STAGE 04 — INSIDE THE ELEMENT
The spiral, from the permeate tube.
Feed spacer, TFC membrane leaf, permeate carrier — wound around the tube you’re travelling down. Salt stays in the brine channel and exits as reject; only water crosses the 0.0001-micron barrier.

YOU JUST WALKED ONE PLANT
We've been building them since 2016.
Excellent Water Industries builds, automates and runs industrial water systems across Gujarat and beyond — RO, ETP, ZLD, STP and pharma-grade loops. Every skid leaves Ahmedabad commissioned, documented and guaranteed in writing.
PRELIMINARY SIZING
Size your plant in ten seconds.
Move the sliders. We'll rough out the array, pump duty and budget band — then you can watch the membrane rack rebuild itself in 3D. Indicative only; final design follows a raw-water analysis.
