Industrial waste disposal and resource recovery are key to sustainable industrial practices. In this state-of-the-art 10-ton dual-stage reverse osmosis (RO) system project, we’ve delivered a comprehensive upgrade to meet stringent environmental and production standards. Here's how we made it possible:

Project Overview

Capacity: 50,000 tons/year.

Processes: Utilizing inorganic acids as decomposition agents, separating useful elements from industrial waste to produce lithium carbonate, synthetic cryolite, magnesium sulfate, and recover high-purity carbon powder and silica byproducts.

Environmental Standards: Effective control and recycling of waste residue, water, and gas, ensuring minimal discharge or compliance with environmental regulations.

Water Source and Quality

Raw Water: Municipal tap water

Characteristics:

•  Turbidity < 0.51 NTU

•  pH: 7.41

•  Total Dissolved Solids (TDS): 447 mg/L

•  Total Hardness: 319 mg/L (as CaCO3)

Required Output:

•  Stage 1 RO Water: Conductivity < 20 μS/cm, Total Hardness < 40 mg/L

•  Stage 2 RO Water: Conductivity < 2 μS/cm, Total Hardness < 1 mg/L

System Design and Workflow

1️. Pre-Treatment:

•  Multi-media filter and activated carbon filter to remove suspended solids and organics.

2️. Primary RO Stage:

•  Removes the majority of salts and impurities.

•  Output used for boiler makeup water.

3️. Secondary RO Stage:

•  Produces ultra-pure water for production processes.

4️. Recycle and Reuse:

•  Stage 2 RO concentrate is recirculated to the raw water tank for maximum water recovery.

Key Equipment:

•  Dual-stage RO units (2 sets, each with 30 membrane elements).

•  Flow Rates:

Stage 1 RO: ≥20 m³/h per unit.

Stage 2 RO: ≥10 m³/h per unit.

Performance and Benefits

✅ Efficiency: Continuous operation with alternating units (1 in operation, 1 on standby).

✅ Water Quality: High-standard desalination ensures process water meets stringent industrial requirements.

✅ Sustainability: Recycled water minimizes waste and environmental impact.
