40 ton havvand om dagen med omvendt osmose i Filippinerne

Project Overview

Bohol Island, a prominent tourist destination in the Philippines, encounters freshwater lacks during the completely dry period. Local groundwater is impacted by seawater intrusion, with TDS values as high as 30,000– 35,000 mg/L, while neighborhood alcohol consumption water need to adhere to the Philippine National Drinking Water Requirement (PNSDW: TDS ≤ 800 mg/L). This job aims to develop a trustworthy Afsaltningssystem til havvand to attend to the everyday water needs of a 200-person neighborhood.

Technical Parameters for seawater reverse osmosis system

• Water Manufacturing Capability 40 m3 / day (scalable to 50 m3 / day)
• Raw Water TDS 35,000 ± 5,000 mg/L.
• Generated Water TDS ≤ 800 mg/L
• Recovery Rate 35%– 40%.
• System Energy Consumption ≤ 4.0 kWh/m FOUR
• Operating Temperature Variety 28– 40 ° C( Tropical climate-adapted).

SWRO System Make-up and Cutting-edge Design

1. Pre-treatment Component.

• Multi-media filter: removes suspended solids (SS ≤ 50 μm).
• Automatic backwashing system: addresses high turbidity salt water during the rainy period (turbidity optimal 40 NTU).
• Range prevention application system: Avoids CaSO four crystallisation (controls LSI < 1.8).

2. Main Treatment Unit.

• Anti-fouling SWRO membrane component: DOW ro membrane (solitary membrane desalination rate 99.6%).
• One-stage pressure increasing arrangement:.
• Stage 1 high-pressure pump (3.5 kW): Increases pressure to 55– 60 bar.

3. Smart control system.

• PLC + HM human-machine interface: Real-time tracking of ORP/TOC/pressure.
• Cloud-based remote management: Sustains fault medical diagnosis (covered by Baohe Island 4G network).

4. Special setting adjustment.

• Container-style real estate: IP55 protection rating, immune to salt fog corrosion.
•  Solar back-up system: 20 kW off-grid power supply (to resolve regular power outages).

Trick Obstacles and Solutions

Challenge	Countermeasures	Effect
High-temperature seawater (33–35°C)	Dynamic membrane flux compensation algorithm	Stable water production ±5%
Frequent typhoons	Foundation securing + wind-resistant ballast style	Endures 10-level winds
Biofouling Shock	chlorine dioxide sanitation (0.5 ppm recurring)	CIP cleaning cycle extended to 90 days
Operational manpower shortage	Automatic chemical cleaning device (CIP)	Only requires monthly inspection once

Water High Quality Confirmation (Third-Party Screening)

Vare	Raw Water (mg/L)	Produced Water (mg/L)	Typical Limitation
TDS	34,852	382	≤800
Chlorides	19,450	196	≤600
Boron	4.8	0.45	≤2.4
Total Colony Count	920 CFU/mL	Not detected	≤100

6. Economic Conveniences.

• Water manufacturing expense: 0.85 USD/m THREE (including procedure and maintenance).
• Yearly water cost savings: 14,600 m ³ (equal to decreasing 5,000 tonnes of shipped freshwater).
• Repayment duration: 3.2 years (contrasted to trucked water cost of 12 pesos/L).

7. Job Highlights.

Bottleneck-free layout: 20% capability redundancy booked to fulfill peak need throughout the traveler period.
Zero wastewater discharge: Focused salt water utilized for salt production at the community salt area (TDS ≈ 60,000 mg/L).
Community empowerment: Training of 3 regional drivers (including 1 lady).

Note: The system has obtained ETWPS accreditation from the Philippine Division of Setting and Natural Resources (DENR) and abide by the DAO 2016-08 water discharge requirements.

8. Continuous Renovation Instructions.

1. Test brand-new graphene membrane layers (laboratory-stage change improvement of 47%).
2. Integrate a rain harvesting system (yearly boost in supply of water of 3,000 m FOUR).
3. Establish a mobile application for water bill settlements (covering 80% of smart device individuals).

This study efficiently demonstrates that modular reverse osmosis technology can achieve trusted water supply with low operational dependency with intelligent style in exotic island scenarios, supplying a replicable freshwater remedy for coastal communities in Southeast Asia.

If a PowerPoint variation of the technical proposal or design layout is needed, CAD/DWG layout in-depth style documents can be supplied.
