HF-4040 High flow reverse osmosis membrane element Ecosoft

The Ecosoft HF-4040 high-flow reverse osmosis membrane element is designed for 4-inch commercial reverse osmosis systems that require high permeate flow with efficient operation at ultra-low pressure. It provides permeate flow up to 10.2 m³/day and supports efficient system operation with reduced operating costs. The membrane is recommended for feed water with TDS up to 1500 mg/L*.

Ecosoft HF membranes are manufactured using technology that ensures long-term and reliable system operation. This membrane is suitable for commercial applications, including domestic water treatment, drinking water production, beverage production, breweries, livestock and poultry farms, aquaculture, greenhouses, mist humidification systems, laundries and the food industry.

* For Ecosoft RO systems operating at 75% recovery and a feed water temperature of 12°C, a feed water TDS of 1500 mg/l typically corresponds to a permeate TDS of approximately 100 mg/l.

Before start-up, ensure that the membrane is properly prepared for operation. Check membrane pretreatment, membrane element installation, instrument calibration and overall system condition.

During start-up, shut-down, cleaning and other maintenance procedures, avoid large pressure surges and flow fluctuations inside the spiral elements, as they can damage the membrane.

During start-up, it is recommended to gradually switch the system from idle to operating mode by performing the following steps:

Gradually increase the feed water pressure over 30-60 seconds,
Gradually restore the system operating flow over 15-20 seconds,
The permeate produced during the first hour of operation must be drained.

After the initial wetting, the membrane must be wet.
To prevent biofouling during prolonged downtime, store the membrane elements in a preservative solution. The pressure drop across the entire length of the housing must not exceed 3.4 bar.
