Water Treatment Equipment

I. Industry Pain Points

1. Substandard water quality for industrial and domestic use, including scaling, excessive impurities and microorganisms, which damages production equipment and impairs product quality.

2. Poor customizability of traditional water treatment solutions, unable to adapt to different water quality and industrial water standards overseas.

3. Complicated equipment operation and maintenance, high failure rate, slow cross-border after-sales response and soaring maintenance costs.

4. Great difficulties in seawater/brackish water desalination, reclaimed water reuse and sewage treatment, resulting in failure to meet environmental compliance requirements.

5. Excessively high prices and long delivery times of imported equipment, while local brands fall short of overseas procurement requirements in terms of technology and qualifications.

III. Product Definition and Core Selling Points

Product Definition

Shandong Little Duck Environmental Protection focuses on the R&D and production of reverse osmosis, ultrafiltration, nanofiltration, water softening, EDI ultrapure water, seawater desalination and sewage treatment equipment. We offer a full-chain service from design, manufacturing, installation and commissioning to after-sales for global customers, meeting the water use and sewage treatment needs of various industries overseas. 

Core Selling Points

1. Full product range coverage for one-stop procurement

Covering reverse osmosis/ultrafiltration/water softening/EDI/seawater desalination/sewage treatment/water supply equipment, it meets the needs of pure water production, water purification, sewage treatment and water supply transformation in one stop, reducing the cost of docking with multiple suppliers. 

2. International quality for stable and durable use

Adopting imported American reverse osmosis membranes and Southern pumps/Grundfos pumps, the membrane service life is up to 3 years. The equipment has passed the three major system certifications of ISO9001, ISO14001 and ISO45001, featuring stable operation and a desalination rate of up to 98%. 

3. Customization to adapt to global water quality

Solutions can be customized according to the conductivity, quality and water output of raw water overseas, adapting to brackish water, seawater, groundwater and municipal tap water, and meeting the standards of Europe, America, Southeast Asia, the Middle East, Africa and other regions.

4. Fully automatic operation with low maintenance

Equipped with PLC intelligent control and fully automatic operation, no special person on duty is required. The pretreatment reduction system protects membrane elements, resulting in a low equipment failure rate and worry-free cross-border use.

5. High water recovery rate for cost reduction and efficiency improvement

With a water recovery rate of more than 65%, low energy consumption and less wastewater discharge, it greatly reduces the production and operation costs of overseas customers in long-term use.

6. Reliable cross-border after-sales support

Providing timely online response, remote commissioning, technical training and spare parts supply to solve cross-border after-sales problems.

IV. Application Scenarios 

1. Industrial pure water/ultrapure water

Electronic chips, electroplating, medicine, food and beverage, boiler make-up water for power plants, process water for chemical engineering

2. Drinking water treatment

Centralized water supply for overseas urban and rural areas, direct drinking water for hotels/schools/hospitals, production of barreled water/mineral water

3. Sewage treatment and reuse

Domestic sewage, industrial wastewater, slaughtering/breeding wastewater, reclaimed water reuse, river course regulation

4. Seawater/brackish water desalination

Preparation of drinking water and industrial water for islands, ships and coastal areas

5. Water supply system

Non-negative pressure water supply for high-rise buildings, constant pressure variable frequency water supply, integrated water and fertilizer supply for agricultural irrigation

6. Special separation and purification

Food fermentation, dairy product concentration, separation of heat-sensitive substances in medicine, ultrafiltration for bacteria and turbidity removal

V. Operation Timing and Frequency

Daily Stable Operation (Routine Production/Water Supply)

1. Industrial pure water equipment: 24-hour continuous operation, automatic flushing 1-2 times a day, routine inspection once a month

2. Drinking water equipment: all-weather water production, weekly self-inspection of water quality, quarterly maintenance of the pretreatment system

3. Sewage treatment equipment: continuous operation according to sewage volume, daily monitoring of effluent indicators, regular sludge cleaning

4. Water supply equipment: real-time constant pressure water supply, monthly inspection of pump units and control systems

Intensified Operation and Maintenance (Water Quality Fluctuation/High-load Period)

When raw water quality deteriorates, during production peak seasons, or in high/low temperature seasons: increase the frequency of water quality testing, maintain membrane elements and filters on a weekly basis; for seawater desalination equipment, increase the frequency of pretreatment when salinity rises.

VII. Frequently Asked Questions

1. Q: Can the equipment adapt to overseas voltage (110V/60Hz) and different water quality conditions?

A: Yes, we can customize overseas voltages such as 110V/60Hz and 380V, and tailor the process according to local raw water (seawater, brackish water, groundwater, tap water) to ensure up-to-standard effluent quality.

2. Q: How long is the service life of membrane elements? Are they easy to damage?

A: Adopting imported reverse osmosis membranes, the service life can reach 3 years under normal use. The equipment is equipped with a complete pretreatment protection system, making it not easy to be clogged or damaged and ensuring strong stability for cross-border use.

3. Q: How to conduct installation and after-sales service for overseas procurement?

A: We provide remote video guidance for installation, commissioning and training; offer 24-hour online response, and can arrange cross-border technical personnel for on-site service (through negotiation) and fast global delivery of spare parts.

4. Q: Can the effluent quality meet local environmental protection/drinking water standards?

A: The equipment can be designed in accordance with WHO drinking water standards, European and American industrial water standards and local environmental discharge requirements, with detectable up-to-standard indicators such as effluent conductivity, purity and turbidity.

5. Q: What is the minimum/maximum treatment capacity? Can it be customized?

A: The treatment capacity is 0.25T/H for small-sized equipment and over 200T/H for industrial equipment. A full set of solutions can be customized according to customers' water volume, floor area and budget.
