Case Study: 3000 LPH RO Plant Installed at JK Lakshmi Cement, Noida (RMC Plant)
Water is the backbone of any Ready-Mix Concrete (RMC) operation. Whether it is used for batching, equipment washing, dust suppression, or curing, the quality and consistency of water directly affects the structural integrity of the final product. For large-scale industrial operations like cement and RMC production, using untreated or poor-quality water is simply not an option.
That is why JK Lakshmi Cement one of India's most respected names in the cement industry chose to partner with Netsol Water to install a high-performance, fully automated 3000 LPH RO plant at their RMC facility in Noida, Uttar Pradesh.
This case study documents the complete project journey from initial assessment and water quality challenges to system design, installation, and measurable outcomes. It also highlights why Netsol Water continues to be the preferred commercial RO plant manufacturer for RMC plant projects across India.

Challenges Faced Water Quality Issues at the RMC Plant
Before the RO system was installed, the JK Lakshmi Cement RMC plant was facing several water quality and supply challenges. The source water at the Noida plant primarily groundwater from borewells had characteristics that made it unsuitable for direct use in concrete production.
Key Water Quality Issues Identified
• High TDS (Total Dissolved Solids): Borewell water TDS levels ranged between 900–1400 mg/L, well above the acceptable limit of 500 mg/L as per IS 456:2000 for concrete mixing water.
• Elevated Hardness: Calcium and magnesium concentrations were high, causing scaling on equipment and affecting concrete mix consistency.
• High Chloride Content: Elevated chloride levels posed a risk of corrosion in reinforcement bars embedded in concrete structures.
• Iron and Turbidity: Suspended solids and iron content caused clogging in pipes and valves, increasing maintenance costs.
• Microbial Contamination: Bacterial presence in the water was detected, which could affect the curing process and final strength of the concrete.
• Irregular Water Supply: The plant lacked a consistent, treated water supply, leading to operational delays during peak production hours.
In RMC operations, using water with excessive TDS or chloride content can lead to a reduction in concrete compressive strength, accelerated corrosion of reinforcement steel, and non-compliance with BIS standards all of which have serious structural and financial implications.
Proposed Solution by Netsol
After conducting a thorough raw water analysis and understanding the plant's daily water demand, Netsol Water proposed a customised 3000 LPH Reverse Osmosis system tailored specifically to the operational needs of the RMC plant.
The solution was designed to:
• Reduce TDS to below 200 mg/L for safe use in concrete mixing
• Eliminate hardness, chlorides, and iron through multi-stage pre-treatment
• Provide a continuous, automated water supply with minimal manual intervention
• Incorporate a robust pre-treatment system to handle the specific characteristics of Noida borewell water
• Ensure BIS IS 456:2000 compliance for all process water used in concrete production
The proposed system was a fully automated, skid-mounted RO plant with SCADA-compatible control panels, enabling the plant operators to monitor performance in real-time and receive alerts for any parameter deviations.
Process Flow: Step-by-Step Working of the RO Plant
The 3000 LPH RO plant installed at JK Lakshmi Cement operates through a well-defined, multi-stage treatment process. Each stage is engineered to address specific water quality parameters, ensuring the output consistently meets industrial and IS standards.
1: Raw Water Collection & Storage
. Borewell water is pumped into a dedicated raw water collection tank (approximately 10,000 litres capacity).
. A float valve system maintains the required water level automatically.
2: Pre-Filtration - Sediment & Turbidity Removal
. Water passes through a multi-grade sand filter (MGSF) to remove suspended solids, silt, and turbidity.
. An activated carbon filter (ACF) removes chlorine, organic compounds, and odour that may affect RO membrane performance.
3: Softening - Hardness Removal
. A water softener (using cation exchange resin with sodium chloride regeneration) reduces calcium and magnesium ions, protecting the RO membranes from scaling.
4: Micron Cartridge Filtration
. Fine particulate matter is removed using 5-micron cartridge filters before the water enters the high-pressure pump stage.
5: High-Pressure Pumping
. A stainless steel high-pressure pump (energy-efficient, 3-phase motor) pressurises the water to force it through the RO membranes.
6: Reverse Osmosis Membrane System
. The core of the system — a bank of 8-inch high-rejection Filmtec/Toray polyamide RO membranes — removes up to 95–98% of dissolved solids, heavy metals, bacteria, and viruses.
. Permeate (treated water) is collected into a product water tank, while reject water is managed through a separate reject management line.
7: Post-Treatment & Dosing
. Antiscalant and pH correction dosing ensures stable system operation and extends membrane life.
. Mineralisation or blending arrangements can be made if required for specific concrete mix parameters.
8: Product Water Storage & Distribution
. Treated water is stored in a UV-treated product water tank (approx. 10,000 litres) and distributed to various plant points including batching systems, mixer washings, and curing areas.
9: Automated Control & Monitoring
. The PLC-based control panel with HMI (Human-Machine Interface) manages all operations — pump start/stop, membrane pressure monitoring, flow rate display, and auto-flush cycles.
. Online TDS meters and pressure gauges provide real-time data logging.

Frequently Asked Questions (FAQs)
Q1. What is the best type of RO plant for an RMC (Ready-Mix Concrete) plant?
For an RMC plant, a high-capacity industrial RO plant with multi-stage pre-treatment is the most effective solution. The system should include a multi-grade sand filter, activated carbon filter, water softener, and high-rejection RO membranes to handle the high TDS, hardness, and chloride content commonly found in borewell water used at RMC facilities. A capacity of 1000 LPH to 5000 LPH is typically sufficient for small to medium RMC operations, while larger plants may require systems of 10,000 LPH or more. Netsol Water Solutions specialises in designing customised commercial RO plants for RMC plant operations across India.
Q2. What is the ideal TDS level for water used in concrete production?
According to IS 456:2000 (the Bureau of Indian Standards code for concrete), the TDS (Total Dissolved Solids) of water used for concrete mixing should not exceed 2000 mg/L as a general guideline, but for optimal results and to avoid any impact on concrete strength and durability, it is recommended to keep TDS below 500 mg/L. Most high-quality RMC operations target TDS below 200 mg/L in process water. A well-designed industrial RO plant can consistently achieve output TDS in the range of 50–200 mg/L, regardless of the raw water quality.
Q3. How long does it take to install a 3000 LPH RO plant at an industrial facility?
For a standard 3000 LPH industrial RO plant installation at a cement plant or RMC facility, the typical project timeline from site survey to full commissioning ranges between 1 to 2 weeks. This includes the initial site assessment and raw water analysis, system fabrication and testing, civil preparation (parallel activity), on-site installation and commissioning with operator training. At Netsol Water, every project is managed with a dedicated project coordinator to ensure timely delivery with minimal disruption to ongoing plant operations.
