SARTHI OS – The Operating System for Water Softeners
SARTHI OS is Purity Hub’s proprietary Water Softener Operating System, engineered to bring intelligence, connectivity, and predictive control to modern water softeners. It transforms a conventional appliance into a smart, self-aware, and protected water treatment system using IoT and AI technology.
Unlike traditional water softeners that operate on fixed timers and assumptions, SARTHI OS continuously monitors real-world conditions such as power availability, water pressure, salt levels, and regeneration performance — ensuring safe, efficient, and reliable soft water at all times.

Why Water Softeners Needed an Operating System
Most water softeners fail not because of poor hardware, but because they operate blindly.
Common real-world challenges include:
1. Irregular power supply
2. Inconsistent water availability
3. Missed salt refilling
4. Incomplete regeneration cycles
5. No visibility into system health
Traditional “automatic” systems cannot adapt to these conditions.
SARTHI OS was built to solve this gap.
It enables water softeners to observe, decide, and act intelligently, instead of following rigid schedules.

What is SARTHI OS?
SARTHI OS is a purpose-built operating system for water softeners, designed by Purity Hub to control, monitor, analyze, and optimize every critical function of the system.
It acts as the digital brain of the water softener by:
1. Continuously collecting operational data
2. Analysing real-time and historical patterns
3. Making safety-first decisions
4. Providing transparency and control to users
In simple terms: SARTHI OS allows a water softener to think before it acts.

Core Principles of SARTHI OS
SARTHI OS is built on five foundational principles that define its behaviour:
1. Customer-First Design
1.1 Reduces dependency on technicians
1.2 Increases visibility and control
1.3 Eliminates uncertainty about system performance
2. Safety Over Aggressive Automation
2.1 Prevents regeneration under unsafe conditions
2.2 Protects resin, valves, and internal components
3. Predictive, Not Reactive
3.1 Identifies issues before failures occur
3.2 Enables planned maintenance instead of emergencies
4. Real-World Adaptability
4.1 Designed for Indian power and water conditions
4.2 Handles power cuts, low pressure, and water shortages intelligently
5. Long-Term System Health
5.1 Extends resin and valve lifespan
5.2 Reduces salt and water wastage

How SARTHI OS Works
SARTHI OS operates through a tightly integrated, multi-layer architecture:
1. Device-Level Intelligence
Embedded IoT hardware connects directly with:
1.1 Power status
1.2 Regeneration activity
1.3 Hold conditions
1.4 Salt alarms
1.5 Valve behaviour
2. Secure Data Synchronization
2.1 Automatic data sync at regular intervals
2.2 Encrypted transmission via Wi-Fi
2.3 Fail-safe handling during connectivity loss
3. AI Analysis Engine
3.1 Processes live and historical data
3.2 Detects abnormal patterns
3.3 Predicts potential system issues
4. User Interface Layer
4.1 Mobile app dashboard
4.2 Real-time system status
4.3 Simple and safe user controls
5. Service Intelligence Layer
5.1 Enables proactive monitoring by Purity Hub (with consent)
5.2 Supports faster, smarter service decisions

Key Features of SARTHI OS
→ Real-Time Water Softener Monitoring
→ SARTHI OS continuously tracks:
→ Power availability
→ Regeneration cycles
→ Station hold status
→ Low salt alerts
→ System activity logs
This ensures the system never operates blindly.
---
Intelligent Regeneration Control
Regeneration is triggered only when:
→ Power supply is stable
→ Water availability is sufficient
→ No safety holds are active
If conditions are unsafe, regeneration is paused or cancelled automatically.
---
Smart Hold & Safety Protection
SARTHI OS places the system on hold when:
→ Water pressure is insufficient
→ Water supply is unavailable
→ Power instability is detected
This prevents:
→ Dry regeneration
→ Resin damage
→ Valve stress
→ Incomplete cycles
---
Low Salt Intelligence
Beyond a simple alarm, SARTHI OS:
→ Tracks duration of low salt conditions
→ Identifies repeated neglect patterns
→ Warns users before performance degrades
---
Activity Logs & Transparency
Every critical event is logged, including:
→ Regeneration attempts
→ Power interruptions
→ Hold activations
→ Salt alerts
→ Manual or remote actions
Users always know what happened and why.
---
AI-Driven Predictive Insights
SARTHI OS analyses trends to:
→ Detect recurring power issues
→ Identify regeneration failures
→ Predict maintenance needs
→ Improve long-term performance
This shifts ownership from reactive to predictive care.
---
Remote Control with Built-In Safeguards
Users can:
→ Trigger regeneration remotely
→ Monitor system health from anywhere
All actions are governed by safety logic to prevent misuse.
---
What SARTHI OS Is Not
To maintain transparency:
→ It is not just a mobile app
→ It is not basic automation
→ It does not blindly force regeneration
→ It does not override safety for convenience
SARTHI OS prioritizes system health over shortcuts.
---
Benefits of SARTHI OS for Homeowners
Immediate Benefits:
→ Peace of mind
→ Consistent soft water quality
→ Reduced service dependency
→ Clear system visibility
Long-Term Benefits:
→ Extended resin life
→ Lower salt and water wastage
→ Reduced unexpected failures
→ Better return on investment
---
Built for the Future
SARTHI OS is designed as a scalable platform, not a one-time feature.
Future capabilities include:
→ Deeper predictive maintenance
→ Advanced performance analytics
→ Smarter regeneration optimization
→ Service automation workflows
---
Why SARTHI OS is a Category-Defining Innovation
Most brands sell machines, Some sell automation. Purity Hub delivers an operating system.
SARTHI OS shifts the conversation from:
Product → Experience
Automation → Intelligence
Ownership → Partnership
---
Final Thought
→ A water softener should not guess.
→ It should not operate blindly.
→ It should not fail silently.
SARTHI OS ensures your water softener understands its environment, protects itself, and delivers consistent soft water — every single day.
