Overview: A leading semiconductor manufacturer in Carmona, Cavite, faced a critical challenge: increasing water demand combined with stringent environmental regulations and a commitment to achieving Net Zero emissions by 2040. With limited access to local water sources and lengthy permitting processes for new deep wells, the company sought a cost-effective and sustainable solution to meet its water needs while adhering to environmental goals. 

CHALLENGES

• Water Demand: The plant required a consistent and large water supply of 15 million cubic meters per year for both industrial processes (such as RODI, cooling towers, and scrubbers) and domestic use (canteen and restrooms). 
• Limited Water Sources: The local water district could not meet the required volume, and developing additional deep wells was not feasible due to time constraints and permitting issues. 
• High Costs: Purchasing water from external suppliers was an expensive option, prompting the need for an internal solution. Sustainability Goals: The company aimed to support its Net Zero 2040 goals by reducing water consumption and minimizing carbon emissions. 

Solution Provided: To address these challenges, a compact and CONTAINERIZED Water Recycling System (WRS) was implemented by MTI. The system, capable of processing 150 gallons per minute, utilized a single-pass, two-stage Reverse Osmosis (RO) process with Multi-Media Filtration (MMF) and Activated Carbon Filtration (ACF) as pre-treatment stages. 

KEY FEATURES

• Cost-Effective: The system provided a financially viable alternative to purchasing water externally. 
• Increased Water Availability: The WRS significantly boosted the plant’s water supply by recycling wastewater. 
• Environmental Compliance: The solution supported the company’s commitment to Net Zero 2040 and sustainable development goals. 
• Quick Implementation: The project was completed within just two months, including installation and commissioning. 
• Ongoing Support: Operations and maintenance services were provided to ensure continuous and efficient system performance. 

RESULTS

• Water Recycling: The system successfully recycled 36,088 cubic meters of water, reducing the plant’s reliance on external water sources. 
• Carbon Emissions Reduction: The recycling process led to a reduction of 382,431 kg of carbon emissions, contributing to the company’s sustainability targets. 
• Enhanced Water Management: The plant effectively addressed its increasing water demand by re-processing wastewater effluent, producing high-quality water for reuse in industrial and domestic applications. 
• Sustainability Impact: The project significantly contributed to the company’s Net Zero 2040 goals and supported the United Nations’ Sustainable Development Goals, showcasing a commitment to environmental stewardship. 

This case study highlights the successful implementation of an innovative and sustainable water recycling solution that not only met operational needs but also advanced the company’s long-term environmental objectives.
