Welcome to Doctor Water!

We are the topmost manufacturer, supplier and trader of quality approved assortment for Reverse Osmosis Plants. Our job is to innovate and manufacture Water Treatment Solutions that bring peace of mind to our customers.

Reverse Osmosis Plant is a Multi-Stage purification unit, and the process involves removal of contaminants from water by using a semi-permeable membrane that permits only water, not the dissolved ions, to pass through its pores. The membranes have microscopic pores that are specially sized to allow water molecules through, while trapping larger inorganic molecules like lead, iron, chromium and arsenic. The membranes come in a variety of pore sizes and characteristics. The contaminated water is subjected to high pressure that forces the pure water through the membrane, leaving the contaminants behind in a brine solution. Studies have shown that RO can be up to 95% effective for removal of As (V). Reverse Osmosis effectively removes nearly all the inorganic contaminants from water. This process removes over 70% of the following:

  • Arsenic-3
  • Arsenic-4
  • Barium
  • Cadmium
  • Chromium-3
  • Chromium-6
  • Fluoride
  • Lead
  • Mercury
  • Nitrite
  • Selenium-4 and selenium-6
  • Silver
When the units are operated properly, ninety-six percent removal rates can be attained. Reverse Osmosis also effectively removes natural organic substances, pesticides, radium and microbiological contaminants. To work effectively, Reverse Osmosis should be used in series. Near 0 effluent contaminant concentrations can be achieved by water passing through multiple units.

How Does A Reverse Osmosis Plant Work?

  • 1. Pre - treatment : This is the stage where an ion exchange column with MnO2, activated carbon media, GS, TS, Sand bed that oxidizes water, splits out chemical bonds of the metals and metalloids present in the water. This stage also arrests turbidity, unwanted particles and the split contaminations that have resulted from the particles present in the raw water.
  • 2. Nano Filtration : The process involves a polypoplene base 5 mµ filter cartridge which arrest very fine and tiny particles, silicon index present in the raw water.
  • 3. RO Block : This stage comprises of the working of the RO block. Here an ultra-modern and superfine nano membrane with a porosity/hole of 0.0001 mµ that is capable enough to remove and arrest the last presence of harmful chemical like As, F, Hg, Pb, Zn is used. The membrane also removes all microbiological contaminations from the raw water.
  • 4. Post Treatment: The last stage, it comprises of an Ultraviolet Treatment involving a process that makes use of ultraviolet light to disinfect the water or reduce the amount of bacteria present.
