Optima Water Solutions is an SWRO Plant Supplier in Kolkata. We design, supply, and commission Sea Water Reverse Osmosis (SWRO) Desalination Plants that produce fresh drinking water and process water from seawater or brackish coastal water. We serve coastal industries, island communities, marine vessels, resorts, and Gulf region clients, with SWRO systems built around energy recovery devices to reduce power consumption.
What is a Sea Water Desalination?
Sea Water Desalination using Reverse Osmosis (SWRO) is the most widely deployed technology globally for converting seawater (TDS 30,000–45,000 ppm) or brackish water into fresh water (TDS below 500 ppm). High-pressure pumps (60–80 bar) force seawater through semi-permeable RO membranes, rejecting 99%+ of dissolved salts.
Modern SWRO plants incorporate Energy Recovery Devices (ERD) such as pressure exchangers that capture energy from the reject brine stream — reducing specific energy consumption to 2.5–3.5 kWh/m³, a 40–60% reduction over older SWRO designs.
SWRO is the primary source of fresh water for the Gulf Cooperation Council countries (Saudi Arabia, UAE, Kuwait, Qatar, Oman, Bahrain) and is increasingly deployed in India's coastal regions as groundwater depletion intensifies.
Sea Water Desalination in Kolkata — Why It Matters
Optima Water Solutions provides Sea Water Desalination design, manufacturing, supply, installation and commissioning support for projects in Kolkata, West Bengal. Local project requirements can vary by wastewater source, capacity, site constraints and intended treated-water reuse.
For Kolkata projects, relevant local considerations include Dankuni Industrial Complex, Kalyani Industrial Area, Falta SEZ, Salt Lake Sector V, Budge Budge Industrial. West Bengal Pollution Control Board (WBPCB) mandates ETPs for industries and STPs for large housing projects in Kolkata. Nearby service coverage includes Howrah, Durgapur, Asansol, Siliguri.

SWRO Capacity & Technology for Kolkata
How we approach Sea Water Desalination projects in Kolkata: we start with the required flow, inlet water or wastewater characteristics, available footprint, discharge/reuse target and operating conditions. The treatment train is then selected around those engineering inputs rather than around the location keyword alone.
Where a site is industrial, commercial, residential or institutional, the final configuration can differ substantially. Our team can handle design, equipment supply, installation, commissioning and ongoing O&M according to the project scope.
Our 4-Step Process — From Design to Handover

Source Water Analysis
Seawater characterisation — TDS, temperature, SDI, biofouling potential, seasonal variation. Site survey.
2
System Design
Intake design, pre-treatment train, SWRO membrane array, energy recovery, post-treatment (remineralisation).
3
Procurement & Fabrication
High-pressure pumps, SWRO membranes (DowDuPont Energy, Toray), pressure exchangers, controls.
4
Commissioning & Certification
Full performance testing. Water quality certification. Operator training. Ongoing O&M support.

Common Questions
Sea Water Desalination in Kolkata — FAQ
How do I choose the right Sea Water Desalination for a project in Kolkata?
The correct Sea Water Desalination depends primarily on flow, feed-water or effluent characteristics, treatment objective, available space and applicable discharge or reuse requirements. Share the project data with Optima and we can recommend the appropriate configuration for Kolkata.
Does Optima supply and install Sea Water Desalination in Kolkata?
Yes. Optima can provide engineering, manufacturing or equipment supply, installation, commissioning and after-sales support for qualifying Sea Water Desalination projects in Kolkata and across West Bengal.
What information is needed for a Sea Water Desalination quotation in Kolkata?
Typical inputs include required capacity, inlet or feed-water analysis, treated-water target, available footprint, operating hours and site conditions. For industrial applications, the process generating the wastewater is also important.
Can Optima provide AMC or O&M support for Sea Water Desalination in Kolkata?
O&M and AMC support can be included where the project scope and service coverage are suitable. The maintenance plan is normally defined around equipment, operating schedule, consumables and required performance checks.
How can I request a Sea Water Desalination proposal for Kolkata?
Send the required capacity, project location, application and available water or wastewater test data through the Optima enquiry form. Our team can then review the requirement and prepare a project-specific proposal.
