BWC200-H Containerized Brackish Water Reverse Osmosis System

In areas where brackish water is widely distributed but fresh water resources are scarce, integrated and highly adaptable desalination equipment is key to meeting water demand. The FENIGAL BWC200-H Containerized Brackish Water Reverse Osmosis System, with a 20-foot standardized container as its carrier, integrates a full set of core components for brackish water desalination. Relying on efficient water production, easy installation and stable performance, it provides a reliable fresh water solution for small and medium-sized communities, agricultural bases, hotels and other scenarios.

I. Core Positioning and Key Advantages of the System

(I) Basic Attributes and Treatment Capacity

As a dedicated containerized model for brackish water desalination in the Desal BWC series, the BWC200-H integrates all core modules (pretreatment, reverse osmosis, cleaning and dosing, control unit, etc.) into one 20-foot standardized container. No additional workshops or protective structures need to be built, significantly reducing on-site construction costs. Its design is based on the working condition of "4,000 ppm, 20°C brackish water", with a rated daily fresh water output of 240 cubic meters (calculated based on a rated water production flow rate of 10 m³/h and 24-hour daily operation). This capacity can meet the daily drinking water needs of approximately 1,000 people or support medium-sized agricultural irrigation.

(II) Key Advantages

1. Rapid Installation and Commissioning: Over 90% of the installation work is completed in the factory. On-site operations only require connecting the water inlet, power supply and drainage pipelines, greatly shortening the commissioning cycle and avoiding the lengthy on-site construction of traditional systems.

2. Strong Corrosion Resistance: High-pressure pipelines and fittings are made of Sch10 SS316 stainless steel, and the container and frame are coated with heavy-duty marine paint. This enables the system to withstand brackish water erosion for a long time and extend the service life of the equipment.

3. Low-Energy Operation: Equipped with a high-efficiency high-pressure pump, IE3-class energy-saving motor and low-energy reverse osmosis membrane, the energy consumption per unit of water production is only 1.56 kWh/m³, which is lower than the average level of similar brackish water desalination equipment in the industry.

4. Easy Maintenance and Rapid Recovery: Standardized general parts are adopted. In case of failure, the system can be quickly restored to operation by replacing parts, reducing downtime losses. At the same time, it is equipped with three-stage filtration (sand filtration, pre-filtration, main filtration) to effectively protect the high-pressure pump and reverse osmosis membrane.

II. Brackish Water Desalination Process and Flow

The BWC200-H adopts a mature reverse osmosis (RO) process, converting brackish water into fresh water that meets drinking water standards through a closed-loop process of "water intake - pretreatment - high-pressure desalination - product water storage". The specific flow is as follows :

1. Water Intake and Storage: Brackish water is pumped by an Intake Pump and sent to a Feed Tank to balance the flow and pressure, preventing water inlet fluctuations from affecting system stability.

2. Pretreatment and Purification:

• The Feed Pump pressurizes the water, and at the same time, Poly Aluminium Chloride (PAC) is dosed to flocculate impurities and Sodium Hypochlorite (NaClO) is dosed for sterilization.

• The water flows through a Sand Filter to remove particulate impurities (the Sand Filter can be omitted if the feed water turbidity is less than 0.3 NTU).

• Sodium Bisulfite (NaHSO₃) is dosed to remove residual chlorine, and an Anti-scalant is dosed to prevent membrane scaling. Finally, the water passes through a Safety Filter to trap tiny impurities, protecting the subsequent high-pressure pump and membrane modules.

3. Reverse Osmosis Desalination: The High-Pressure Pump (HPP) pressurizes the pretreated water to 20 barg (maximum system pressure) and sends it to the 8040-type reverse osmosis membrane modules. Water molecules pass through the membrane to form fresh water, while high-salinity concentrated water is discharged after pressure relief.

4. Product Water and Maintenance: Fresh water is stored in a Product Tank for later use; the system is equipped with a Cleaning in Place (CIP) device to regularly clean the membrane modules and maintain desalination efficiency.

III. Key Technical Parameters of BWC200-H

The following parameters are designed based on "4000 ppm, 20℃ brackish water":

IV. Water Quality Standards and Applicable Scenarios

(I) Inlet and Outlet Water Quality Requirements

BWC200-H has clear restrictions on the quality of influent water. If it exceeds the specified range, additional pre-treatment is required. The effluent fully complies with WHO drinking water standards. The specific parameters are as follows:

(II) Applicable Scenarios

With its flexibility and adaptability, the BWC200-H can cover a variety of brackish water desalination demand scenarios:

• Small and Medium-Sized Communities/Towns: Provides daily drinking water for villages and suburban communities far from municipal water supply.

• Agricultural Planting Bases: Treats underground brackish water to provide fresh water that meets irrigation standards for cash crops, fruits and vegetables.

• Hotels/Resorts: Meets the domestic water and service water needs of accommodation facilities in coastal or inland brackish water areas.

• Mining Camps: Provides stable fresh water for the staff living areas of remote mining areas, ensuring the normal operation of production and life.
