What factors need to be considered when pre-treating water for reverse osmosis equipment?

Reverse osmosis (RO) equipment is specialized water treatment equipment that uses membrane separation technology to treat water, enabling wastewater to reach a level suitable for direct use. However, before operating RO equipment, some pretreatment is necessary. What factors need to be considered during pretreatment? Shijiazhuang Tianwang Environmental Protection will provide a detailed explanation below.

　　For proper operation of reverse osmosis equipment, pretreatment is crucial. Without pretreatment, the equipment may malfunction, typically affecting the membrane. Membrane issues lead to substandard water quality after filtration. Pretreatment involves using three types of filters: quartz sand, activated carbon, and a water softener. The main purpose is to prevent equipment blockage.

　　Two key aspects to consider during reverse osmosis pretreatment are the source water's pH and temperature. Pretreatment must account for the source water's pH to ensure optimal membrane performance. High temperatures increase water permeability; therefore, the temperature should be kept between 20 and 40 degrees Celsius.
