Industrial Reverse Osmosis Plant to Treat Reclaimed Waste Water 400,000 GPD - Egypt

Product Description

Overview: This industrial reverse osmosis plant was designed to treat reclaimed waste water and reduce silica and hardness for boiler feed usage in a steel manufacturing facility in Egypt.

Industry: Boiler Feed

Water Concern: In efforts to conserve water usage, this facility intended to use recycled wastewater to supply their boiler feed system. Due to the nature of water recycling, proper water treatment must be in place to ensure the boiler system runs efficiently. Two major contaminants that certainly effect the performance of a boiler system are hardness (calcium and magnesium) and silica. These two contaminant issue areas are known to cause scaling and buildup in the boiler system. Therefore, their reduction is prioritized to ensure the performance of the boiler feed system is not affected.

Applied Solution: An industrial reverse osmosis plant was recommended for the application of boiler feed to this steel manufacturing facility. The plant consisted of a two-round process. The first round included two brackish RO systems that produce 400,000 GPD and manage 2,000 PPM TDS. The second round was used to recycle the reject of the first sound and consisted of two brackish RO systems that produce 66,000 GPD managing 10,000 PPM TDS to thoroughly purify the concentrate of contaminants. This unique design allows the customer to optimize on the permeate production and further conserve water.


This plant included two RO model #BW-600K-14780-2 and two BW-87K-3680-10 systems from our RO-500 Series.

Treated Waste Water Effluent by Reverse Osmosis System Egypt 400,000 GPD | 02:22

Reclaim of water back into industrial water applications involves a comprehensive knowledge of process design, water chemistry, membrane systems, instrumentation and control. Pure Aqua has been involved in many studies to reuse as much water as possible within numerous water systems and work towards minimal discharge. In this Application we used a 2nd pass RO system to treat the reject water from the main RO system. Features • SS 304 Skid mounted systems • Hydranautics Membranes CPA5-LD and SWC6-MAX • Grundfos High Pressure Pump • Pressure Transmitters • Advanced PLC Control Panel • Chlorine Analyzer • FRP Pressure Vessels rated at 300 PSI • SCH 40 SS High Pressure Piping • Lower CAPEX • Lower OPEX • Better Filtrate Quality • Reuse Wastewater Streams For more information, please visit our website:
