Changes in raw water quality and environmental conditions will lead to changes in the water purification capacity of ultrapure water systems; unsuitable raw water and environment may cause fouling and damage to membrane modules. Selecting a reasonable pre-processor can improve the quality of raw water, thereby enabling the equipment to operate in optimal condition.
Operating parameters of UPU series small ultrapure water system
The UPU series of small ultrapure water machines uses tap water as the raw water source, and the raw water conditions are water that meets the hygiene standards for drinking water.
The UPU series of ultrapure water purifiers uses pure water as the raw water source, producing pure water/distilled water/deionized water with a raw water conductivity of ≤10us/cm.
Water source is tap water for this model | The water source is a pure water machine. |
Minimum water supply pressure: 0.10 MPa Maximum water supply pressure: 0.40 MPa | Minimum water supply pressure: 0 MPa Maximum water supply pressure: 0.40 MPa |
Water temperature: 5～45℃ | Water temperature: 5～45℃ |
pH range: 4–9 | pH range: 5-7 |
Total dissolved solids: TDS ≤ 200 ppm | Total dissolved solids: TDS ≤ 5 ppm |
Residual chlorine: ≤ 0.3 mg/L (ppm) Total iron: ≤ 0.3 mg/L (ppm) Manganese: ≤ 0.1 mg/L (ppm) |
Precautions
( 1) If the raw water has high hardness (TDS value exceeds 200mg/L), a UPU water softener should be selected for pretreatment;
( 2) If the raw water has a high iron and manganese content (>0.5mg/L), a UPU iron and manganese removal filter should be selected for pretreatment.
Power supply: AC 220V/50HZ with safety grounding
