Reverse Osmosis (RO) is one among the foremost important ways of purifying water and making it safe for drinking. This purification method has been practiced for several years now. Initially it had been intended for industrial purpose, but after seeing the effectiveness of the system in purifying water, it had been then adopted for commercial and residential use. RO system have wide application from clean beverage to dialysis healthcare applications. RO may be a membrane-based demineralization technique wont to separate dissolved solids from solution. it's the method by which an applied pressure, greater than pressure , is exerted on compartment that when contained high-concentration solution. This pressure forces water to undergo the membrane within the direction reverse thereto of osmosis which help for the water purification.
Typical components of RO System:
Raw pump : to get the pressure for down the road system
Multi Grade Pressure Sand Media Filter: The water is first filtered by pressure sand filter unit for removal of suspended matters and turbidity.
Activated Carbon Media Filter: to get rid of colour, odour, chlorine, oil & grease from the raw water.
Micron Cartridge Filter (MCF): These are pressure vessels fitted internally with spun or pleated cartridge element, which removes micron sized particles.
Antiscalant Design System: to stop membrane from scaling (hardness).
High Pressure Pump: A high-pressure pump is provided for supplying the feed water to RO System at high .
RO Membrane: membrane to get rid of ions, molecules, and bigger particles from beverage . It contains polyester base, polysul phone layer and Polyamide layer and every one these layers are rolled together within the sort of a tube.
Classification of RO System:
Small capacity – Generally having a capacity of but 100 liters per hour (LPH) and compact, utilized in household purposes.
Medium capacity – Generally having a capacity range of 500 – 1000 LPH, utilized in household, apartments, offices, small factories, etc.
Large Capacity / Industrial RO Plants – Capacity having quite 1000 LPH. Applicable for bottling plants and water treatment for chemical industries.
Common Failures in RO System
In order to scale back the failures of RO plant, remote monitoring & predictive maintenance system shall be implemented using NEERO – an online of Water System which applies Internet of Things technology. NEERO enable real time remote monitoring and analytics by obtaining RO system data from various sensors and transducers for measuring TDS, pressure drop, temperatures, flow of water, water level, pH value etc. and connected with an gateway. the info collected is communicated through GSM to cloud web/mobile application where the info are interpreted by using NEERO algorithms for the upkeep manager or RO system service team diagnosis to enable preventive and predictive maintenance of the RO system. NEERO are often directly installed with RO system through retrofitting or interfacing with the instrument panel of the RO system to retrieve data and further analytical insights and actions.
