Background
With climate change and global urbanization accelerating, pressure on water resources, demand for industrial water efficiency,
and environmental regulations are all driving rapid growth of the water treatment industry.
According to Grand View Research, the global water pump market was valued at USD 71.86 billion in 2024
and is projected to reach USD 92.22 billion by 2030, with a CAGR of 4.4%.
In addition, MarkNtel Advisors reports that the pumps used in the chemical industry segment
is expected to grow from USD 5.88 billion in 2024 to USD 6.88 billion by 2030, with a CAGR of 3.06%.
The Role and Applications of NaOH in Water Treatment
Sodium hydroxide (NaOH, also known as caustic soda) is one of the most widely used basic chemicals in water treatment.
It is mainly applied to neutralize acidic wastewater, adjust pH levels, prepare coagulants to promote sedimentation,
and stabilize chlorine disinfection in municipal water treatment.
Because NaOH is highly corrosive, the transfer process places strict demands on pump materials and long-term stability.
Choosing the right NaOH transfer pump solution is therefore a critical part of any water treatment system.

📌 NaOH Transfer in Water Treatment: How to Reduce Energy Use, Noise, and Enhance Automation?
Case Study Client – Hardman Chemicals / DGL Group, Australia’s Hazardous Chemical Logistics and Water Treatment Chemical Supplier
Current Situation
Hardman Chemicals / DGL Group is one of Australia’s leading hazardous chemical logistics and water treatment chemical suppliers.
At its facilities, sodium hydroxide (NaOH) solution transfer relies heavily on pumping equipment.
In the past, Hardman Chemicals used a Wilden 1" Air-Operated Double Diaphragm Pump (AODD) for NaOH transfer, but encountered issues such as high noise levels and limited installation space.
Improvement Goals
- 1. Reduce energy consumption
- 2. Lower noise and improve working environment
- 3. Decrease maintenance frequency and cost
- 4. Provide PLC connectivity for automated monitoring
- 5. Retain self-priming and dry-run capability of diaphragm pumps
💡QUANTM EODD Pump Eliminates AODD’s High Energy Use and Noise Issues
在既有的 NaOH 水處理輸送系統中，Hardman Chemicals 將原有氣動隔膜泵，直接替換為 QUANTM i30 電動隔膜泵，能效提升 ，噪音、維護成本也降低，更可連接PLC智慧監控。
- 能效提升 5 倍：不再依賴壓縮空氣，顯著降低能源消耗。
- 運轉更安靜：噪音從 >75 dB 降至約 61 dB，作業環境改善。
- 維護成本降低：免除空壓管路與壓縮機維護。
- 零佔地增加：泵體尺寸 250 × 310 mm，可與原有框架直接替換。
- 智慧監控：內建 Modbus-RTU，可直接串接 PLC，即時上報運行參數。

FAQ
Q1：氫氧化鈉溶液用什麼泵輸送?
A：氫氧化鈉NaOH 屬於高腐蝕性鹼液，長時間接觸容易造成泵體與管路損耗，若材質不耐腐蝕，會導致洩漏與維護頻繁。因此選用 PP 泵體、PTFE 隔膜 的 電動隔膜泵，能大幅提升輸送穩定性與耐用性。
Q2：水處理中的 NaOH 輸送會遇到哪些常見問題？
A： 在水處理系統中，NaOH 輸送常面臨多重挑戰，例如傳統 AODD 泵依賴壓縮空氣，導致能源效率偏低；運轉時噪音影響操作人員的舒適度；此外，由於 NaOH 對密封件具強腐蝕性，泵浦經常需要停機檢修，維護頻率高；再加上缺乏數位化功能，無法即時回傳運行狀態，異常只能依賴人工巡檢，降低了整體系統效率。
Q3：輸送 NaOH 時是否能避免氣蝕或空轉風險？
A： 若要避免氣蝕或空轉，選購時要注意 泵浦是否具備足夠的自吸能力與耐乾轉設計。
QUANTM 保留了隔膜泵 自吸與乾轉 的特性，可自吸高度達 6 公尺，並可允許 30 分鐘乾轉，有效降低 NaOH 輸送過程的氣蝕與中斷風險。
Q4：QUANTM 在工業廢水處理 NaOH 投藥中有什麼優勢？
A：QUANTM 不僅能精準控制流量與壓力，還能透過 Modbus-RTU 串接 PLC，即時上報 NaOH 投藥數據，確保 pH 調整穩定，符合水處理排放法規。
