Equipment Features

The filtration process of this reverse osmosis equipment model is as follows: the raw water pump provides water pressure, and the water flows through FRP/stainless steel tanks (including quartz sand filters, activated carbon filters, and water softening systems) before entering the PP precision filter. It is then pressurized by a high-pressure pump and injected into the reverse osmosis system to produce pure water. The entire set of equipment is controlled by a fully automatic electronic control system and can be linked with the pure water tank to achieve fully automatic operation and production. When the water level in the tank is too low, the reverse osmosis equipment will automatically start producing water and inject it into the tank; when the tank is full, the float valve will send a signal to the control system, and the equipment will stop running immediately. Large-scale reverse osmosis (RO) equipment is mainly used in purified water production plants for filling bottled water or barreled water.

Raw water is pumped through pretreatment units—quartz sand filter, activated carbon filter, and water softener—to remove large particles, chlorine, color, and hardness. Then it passes through a PP precision filter for fine filtration. A high-pressure pump pushes the water into the reverse osmosis (RO) membrane. The RO membrane allows water molecules to pass through while rejecting dissolved salts, organics, and bacteria. The produced pure water flows into the pure water tank, and the concentrated wastewater is discharged. The automatic control system starts or stops the equipment according to the tank water level and float valve signal.

Supplementary Note:
The system offers reliable filtration, stable water quality, and simple automatic operation with low maintenance. It is suitable for continuous production and can be customized according to raw water quality and required capacity.
