Reverse Osmosis / De-Salination
Reverse Osmosis technology has grown to a large extent in the last decade. The industry has benefited by the introduction of higher efficient, rugged and energy saving membranes.
Aqua Designs offers range of Reverse Osmosis plants to meet individual and industrial requirements. Aqua Designs is backed by the world's leading membrane manufacturers like Hydranautics-USA and Toray-Japan.
Aqua Designs interacts on a continuous basis with membrane manufacturers with a feedback on their field experience and receives the latest developments on R&D and global feed back in turn. This provides Aqua Designs with a unique advantage of exposure to global applications with their in-house field experience and results in Aqua Designs incorporating several design features that give the equipment, superior reliability, greater ENERGY SAVINGS and longer life under field conditions.
The heart of the reverse osmosis system are the “membranes”. Aqua Designs realizes the importance of this and strictly designs all its systems as per the guidelines of the membrane manufacturers. All Reverse Osmosis systems are designed utilizing the latest generation spiral wound thin film composite polyamide membranes. These membranes have extremely high resistance to fouling and offer the best energy savings achievable globally.
The Reverse Osmosis units are designed in a compact skid with easy access to monitoring check points, sample valves. These features come from the extensive field experience of Aqua Designs in operating and maintaining the plants in over 6 countries. The standard systems are offered with the manual option and field instruments to monitor the performance and necessary safety interlocks to protect the membranes.
Advanced automation packages with the basic version starting from a PLC based control with auto flushing, with upgradation to a DCS - SCADA based control with real time logging and provision for either a wired or a remote communication to other locations. Aqua Design's automation packages are user friendly and flexible with respect to data access and data logging. Adequate security features with supervisory control with access codes are also provided.

Industrial RO Units
Aqua Designs offers industrial models to meet the brackish water treatment requirements of industries. The industrial units are constructed based on a process expertise and field experience of Aqua Designs, backed by leading membrane manufacturers like Hydranautics and Toray.
Industrial units are custom built to meet a variety of applications to suit individual customers. Precise engineering helps to produce RO systems that are efficient and dependable for years. All industrial units utilize the state of the art latest generation thin film composite polyamide membranes.
The Reverse Osmosis block is built as a compact and rugged skid with aesthetic piping. Aqua Designs offers an option of stainless steel / FRP housing for the membranes. The piping for the RO systems is available in normal SS 304 / SS 316 to higher versions like electro-polished stainless steel for specific applications. The basic versions are offered with manual option with online monitoring instrumentation with all safety interlocks, and a completely pre wired control panel and an electrical switch gear panel.
The basic versions can be easily upgraded to a high level of automation with either a PLC based control system or SCADA based control system with real time monitoring.
Sea Water Deslination
Aqua Designs offers Sea water desalination reverse osmosis plants for production of low TDS permeate from sea water. The sea water desalination units are constructed based on a process expertise and field experience of Aqua Designs backed by leading membrane manufacturers like Hydranautics and Toray.
The desalination units are custom built in combination with a site specific pre treatment and sea intake system. The pre treatment section is designed based on the input sea water quality and ensures that the right quality of sea water is provided as feed to the RO at all times.
