Desalination Plant Solutions
Water availability is no longer just an operational issue—it is a boardroom-level risk and a critical engineering constraint. Coastal industries, expanding cities, and infrastructure assets are increasingly facing freshwater scarcity due to groundwater salinization, climate variability, and rising demand. A Desalination Plant converts seawater or brackish sources into reliable, specification-grade water for drinking, utilities, and industrial processes.
HECS delivers Seawater Desalination Plant and industrial desalination systems across India and global markets, covering design, construction, commissioning, and long-term performance support.
Desalination Technologies Offered by HECS
Reverse Osmosis (RO) Desalination
A Seawater RO Plant is preferred where power availability and footprint efficiency are key considerations.
Key advantages
Modular capacity expansion
Rapid start/stop operation
Energy recovery in desalination using pressure recovery devices
Defined CAPEX/OPEX with performance guarantees
Applications
Coastal industrial estates
Ports and municipal supply augmentation
EPC infrastructure projects
Thermal Desalination Systems
Thermal systems are selected where waste heat is available or very high reliability is required.
Multi-Stage Flash (MSF): High-uptime systems for large-scale projects.
Multi-Effect Distillation (MED): Lower operating temperatures with improved scaling control.
Mechanical Vapor Compression (MVC): Compact systems suited for medium industrial capacities.
Modular & Mobile Desalination Solutions
HECS provides containerised desalination units for urgent or temporary water needs, including:
Construction water for coastal EPC projects
Emergency supply during droughts or pipeline failures
Temporary production support during shutdowns
Modular systems reduce site work and accelerate commissioning.
Industrial & Sector-Specific Applications
Desalination for industries requires sector-specific engineering:
Power plants: Cooling and utility water with demin integration
Oil & gas: High-reliability utility water systems
Fertilizers: Stable water quality to protect equipment
Ceramics & manufacturing: Process water consistency
Municipal projects: Drinking water desalination aligned with standards
Other industries: Customized desalination for varied process and utility needs
HECS executes projects from compact industrial systems to large-scale desalination plants, including MLD-range deployments where feasible.
How a HECS Desalination Plant Works
A practical desalination water treatment system follows these stages:
1) Seawater Intake
Water is drawn through open intakes or beach wells based on site conditions. Proper intake design limits silt load, marine growth, and chemical demand.
2) Pre-treatment
Ensures stable feed quality using screening, coagulation, clarification, media filtration, or UF systems—controlled through turbidity and SDI monitoring.
3) Desalination Process
Reverse Osmosis Desalination: High-pressure pumps force seawater through membranes to separate salts from permeate.
Thermal Desalination Plant: Uses heat-based separation through evaporation and condensation.
4) Post-treatment
Includes pH correction, remineralisation for potable water, disinfection, and corrosion control for industrial systems.
5) Storage & Distribution
Hygienically designed storage and pumping systems ensure redundancy and demand stability.
6) Brine Management
Brine is managed through marine outfalls, diffusers, evaporation, or reuse/ZLD strategies aligned with local regulations.
