Real deployments.
Measurable outcomes.

Challenge: Eagle Group's 4,500-person complex was spending HKD $2.4M per year on bottled water, with high-TDS (380 ppm) feed water creating compliance and hygiene reporting risks.

Solution: Pulserac deployed an MDZN 500 unit in 8 days under a Zero CAPEX service agreement. PDT disaggregates dissolved solids — no membranes, no chemicals — continuously monitored across 14 IoT parameters by the Hong Kong NOC, 24/7.

Result: TDS dropped from 380 ppm to 74 ppm, saving HKD $1.82M per year and eliminating 87,000 single-use plastic bottles — with water quality data feeding directly into Eagle Group's ESG reporting.

"The water quality data feeds directly into our hygiene management system — it's become a core part of our ESG reporting."

Challenge: Sing Kee's 12-location F&B chain had no quality guarantee across sites — inconsistent water was affecting espresso extraction and beverage taste, while bottled water costs compounded to a significant annual overhead.

Solution: An MDZN 200 unit was deployed at each location within 10 days per site under Pulserac's Zero CAPEX, 3-year minimum SLA. PDT treatment brought turbidity below 0.09 NTU uniformly across all twelve outlets, backed by Swiss Federal FDWO certification.

Result: Total annual saving reached HKD $430K, with 156,000 plastic bottles eliminated and consistent sub-0.09 NTU water quality lifting espresso extraction and beverage presentation across all 12 sites.

"The difference in espresso extraction was immediate. Our baristas noticed it within the first shift."

Challenge: Guest complaints over mineral taste and a bottled water cost of HKD $0.38/L across restaurant, banqueting, and in-room amenities were dragging OPEX at Wyndham Grand's 650-room property.

Solution: Pulserac installed MDZN 800 units across 3 separate water loops under a Zero CAPEX SLA. PDT maintains pH at 7.1–7.4 throughout all loops, monitored in real time across 14 IoT parameters via the Hong Kong NOC. HK WSD and Swiss Federal FDWO certified.

Result: Water cost fell from $0.38/L to $0.071/L — a 10× reduction — eliminating 240,000 plastic bottles annually and removing the in-room bottled amenity line to strengthen sustainability positioning with MICE and corporate clients.

"We eliminated the plastic bottle line from our in-room amenity budget entirely. The sustainability story plays well with our MICE clients."

Challenge: With 30+ properties across three regulatory jurisdictions — HK, Macau, and GBA — fragmented bottled water logistics and inconsistent compliance were escalating OPEX and operational complexity.

Solution: Pulserac deployed a fleet of MDZN 200–800 units scaled to each property under a unified Zero CAPEX agreement. All units stream 14 IoT parameters to Pulserac's centralised HK NOC, giving China Travel Service a single portal to monitor every property 24/7.

Result: A Q4 2023 independent laboratory sweep recorded a 100% pass rate across all 30+ properties, with 30 separate site-management tasks consolidated into one NOC dashboard.

"The centralised dashboard means our facilities team monitors 30 sites from one screen."

Challenge: Aging pipework raised lead contamination risk for 800 primary school students, with no mechanism to provide parents verifiable, ongoing water safety assurance beyond periodic third-party tests.

Solution: Pulserac installed an MDZN 100 unit under a Zero CAPEX agreement, treating all drinking water at point of use without chemicals or membrane replacement. Monthly independent laboratory reports are generated automatically under the SLA.

Result: Monthly lab results — validated by HKUST Guangzhou and Macau Institute — are published on the school's parent portal, with bacterial load at ND and heavy metals below WHO detection limits.

"Parents can check the water quality log on our parent portal. It's been a significant trust-building exercise."

Principal, Lee Shiu Kan Memorial School

Challenge: With no municipal supply, China State Construction was trucking in bottled water for 2,200 workers at HKD $1.2M per year — generating site delays and growing plastic waste ESG liability.

Solution: Pulserac deployed an MDZN 300 unit in 10 days, treating the on-site raw water source directly using PDT — no membranes, no chemicals. The unit delivers 42,000 litres per day at $0.071/L, continuously monitored via the Hong Kong NOC under a Zero CAPEX SLA.

Result: Eliminating the water truck contract saved HKD $1.2M per year; worker sick days dropped in Q1, and the project recorded zero plastic bottle waste from water provision.

"Eliminating the water truck contract alone justified the whole programme. Clean water on-site also reduced sick days in Q1."
