What are the components of pure water equipment and what is its function?

Preparation technology of pure water equipment

1, pretreatment → reverse osmosis → intermediate water tank → water pump →EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed →0.2 or 0.5μm precision filter → water object (≥ 18ω. cm)。

2. Pretreatment → primary reverse osmosis → dosing machine (PH adjustment) → intermediate water tank → secondary reverse osmosis (positive charge reverse osmosis membrane) → pure water tank → pure water pump →EDI device → ultraviolet sterilizer →0.2 or 0.5μm precision filter → water user (≥ 17ω). cm)。

3. Pretreatment → reverse osmosis → intermediate water tank → water pump →EDI device → pure water tank → pure water pump → ultraviolet sterilizer →0.2 or 0.5μm precision filter → water object (≥ 15 mω. cm)。

What's the role?

(1) Raw water tank, function: it stores raw water in the system, which plays a regulating role in water inflow and also has a certain precipitation effect on impurities in water inflow.

(2) Sand filter, function: preliminarily remove suspended solids and other particles in water, and reduce the turbidity of water.

(3) Activated carbon filter, function: using the principle of activated carbon adsorption to adsorb residual chlorine in water with different colors and smells.

(4) Water softener, function: use cationic resin to replace calcium and magnesium ions in water, and reduce the hardness of water.

(5) Security filter, function: prevent large particles of impurities from entering the reverse osmosis membrane, causing damage to the membrane and protecting the reverse osmosis membrane.

(6) Two-stage reverse osmosis main engine, function: mainly through reverse osmosis filtration, to achieve the purpose of producing pure water.

(7) Primary pure water tank, function: to store reverse osmosis water and supply water for secondary reverse osmosis system.

(8) Pure water tank, function: to store the water produced by secondary reverse osmosis and provide water for the terminal water purification point.
