If the filtered water quality is significantly reduced, the TDS value (total dissolved solids) is increased, or the water outlet speed is significantly slowed down, the reverse osmosis membrane should be considered for replacement.

Water treatment equipment in the glass industry includes: 1. Filtration equipment 1.1 Sand filter 1.2 Activated carbon filter 2. Ion exchange equipment 3. Ultrafiltration equipment 4. Reverse osmosis equipment 5. Neutralization equipment 6. Biological treatment equipment

LPH is the abbreviation of "Liters Per Hour", which means "liters per hour". Therefore, 500 LPH means that the reverse osmosis equipment can process 500 liters of water per hour. This label is usually used to describe the water production capacity or water treatment volume of the equipment.

A reverse osmosis system (RO system) is a multi-stage water treatment process that uses a semi-permeable membrane and pressure to remove contaminants from the water, producing clean drinking water.
