Case Study: Installed 8000 LPH RO Plant at Elixa Technologies, Uttarakhand
Netsol Water designed, installed and commissioned an 8000 LPH RO Plant at Elixa Technologies in Uttarakhand. The project was undertaken to give the client a dependable source of treated water at a capacity suited to its daily operational needs.
The installation is a Reverse Osmosis based water treatment system, engineered to reduce dissolved solids and impurities from raw water and deliver consistent, good quality treated water. The scope of work covered system design, supply of equipment, on-site installation, piping and electrical integration, testing and final commissioning.
As the executing partner, Netsol Water's role covered the complete project lifecycle, from initial requirement assessment to handover of a functioning 8000 LPH RO Plant ready for daily operation.
About Elixa Technologies
Elixa Technologies is the client for this project, based in Uttarakhand. The facility required a higher capacity water treatment system to support its day-to-day water usage. Elixa Technologies is a technology-driven cleantech company serving industrial applications, with solutions focused on water management, process efficiency and wastewater treatment. The company has worked with industries where efficient water use and wastewater management are important operational requirements.
Reliable treated water matters for any facility that depends on consistent water quality for its daily functioning, whether for process use, utility use or general facility requirements. For Elixa Technologies, having a plant capable of producing 8000 litres of treated water per hour was central to meeting that requirement without interruption.
Client's Water Treatment Requirement
Before the project, Elixa Technologies needed a water treatment system that could match its operational water demand while delivering water of consistent quality. The requirement can be summarized as follows:
. Required water capacity: a treatment system capable of producing approximately 8000 litres of treated water per hour.
. Water quality requirement: reduction of dissolved solids and impurities to a level suitable for the client's intended use.
. Raw water source: borewell Water.
. Intended use of treated water: process use, utility use, general facility use.
. Consistent water quality: the client needed treated water output that did not fluctuate significantly with changes in raw water condition.
. Operational requirements: a system that could run reliably on a daily basis with manageable monitoring and maintenance needs.
Given this combination of capacity and consistency requirements, an 8000 LPH RO Plant was identified as the appropriate scale of system for the facility's daily water demand.
Challenges Before RO Plant Installation
Every water treatment project begins with an assessment of the raw water condition and site constraints. For this project, the challenges considered during planning included:
. Raw water quality: High TDS.
. Requirement for consistent treated water output despite possible variation in raw water quality over time.
. Need for a system sized correctly for the facility's actual water demand, avoiding both under-capacity and unnecessary over-sizing.
. Space and layout considerations for equipment placement within the available site area.
. Operational requirement for a system that the client's team could monitor and run without complex intervention.
Only the challenges confirmed as part of the project scope are listed here. Where specific raw water quality data such as TDS or hardness values has not been documented for this site, it should be added from the actual project or laboratory records before publishing.
Proposed 8000 LPH RO Plant Solution
To meet Elixa Technologies' requirement, Netsol Water proposed a complete 8000 LPH RO Plant solution built around the following stages:
. RO capacity: a system rated for 8000 litres per hour, sized to match the client's daily water demand.
. Pretreatment: removal of suspended solids and larger impurities before the water reaches the RO membranes, which protects the membranes from fouling and extends their working life.
. Cartridge filtration: fine filtration stage that removes finer particulate matter that pretreatment filters may not capture, safeguarding the high-pressure pump and membranes.
. High-pressure pumping: generates the pressure needed to push water through the semi-permeable RO membranes.
. RO membrane system: the core treatment stage where dissolved salts and impurities are separated from the water, producing purified permeate.
. Control and monitoring: instrumentation and control panel to track flow, pressure and system performance during operation.
. Treated water storage: a storage tank to hold treated water for the client's use as required.
. Reject water management: a defined path for the RO reject stream so it can be discharged or reused as per site requirements.
Each of these stages plays a specific role. Skipping or under-sizing pretreatment, for example, tends to shorten membrane life, while inadequate monitoring makes it harder to catch performance drift early. The system for Elixa Technologies was configured to address these considerations at the 8000 LPH scale.
RO Plant Process Flow
The treatment process at Elixa Technologies follows a standard RO sequence, adapted to the 8000 LPH capacity of the plant:
Raw Water
↓
Pretreatment
↓
Fine Filtration
↓
High-Pressure Pump
↓
RO Membrane System
↓
RO Permeate
↓
Treated Water Storage
Pretreatment: raw water first passes through stages such as sand filtration to remove suspended solids and, where required, activated carbon filtration to reduce chlorine and organic matter.
Why filtration is required before RO: RO membranes are sensitive to particulate matter and certain chemicals. Filtering the water beforehand prevents premature fouling and damage to the membranes.
Role of the high-pressure pump: it supplies the pressure needed to push water across the RO membrane surface, overcoming the natural osmotic pressure of the dissolved salts.
How RO membranes remove dissolved impurities: the semi-permeable membrane allows water molecules to pass through while blocking a large proportion of dissolved salts, minerals and other impurities.
Permeate versus reject: permeate is the purified water that has passed through the membrane, while reject is the concentrated stream that carries the separated salts and impurities away from the system.
This sequence reflects the general configuration used for the project. The exact pretreatment stages and instrumentation should be confirmed against the actual site drawings and equipment list before publishing.
