Products and Services by Segment

1. The Water Segment

The Water segment is the company's established core business, focused on providing energy recovery solutions for the water purification and treatment industries. Its technology is instrumental in making high-pressure fluid-flow processes, particularly Reverse Osmosis (RO) desalination, significantly more energy-efficient and affordable. The adoption of Energy Recovery's products has been cited for cutting plant energy consumption by up to 60%, preventing hundreds of thousands of metric tons of carbon emissions annually.

Core Water Products

• PX Pressure Exchanger (PX Technology):
  • Function: The PX Pressure Exchanger is a rotary positive displacement device that captures pressure energy from the high-pressure reject (or brine) stream of a reverse osmosis system and transfers that energy directly to a low-pressure feed stream. This process is accomplished without any energy conversion to electricity or mechanical work, resulting in a direct hydraulic transfer.
  • Efficiency and Mechanism: It is widely considered the gold standard for energy recovery in Seawater Reverse Osmosis (SWRO) applications, boasting up to 98% efficiency in pressure transfer. The device features a single, central ceramic rotor that is the only moving part. This rotor spins within a ceramic sleeve, with a narrow water gap acting as a virtually frictionless hydrodynamic bearing, which eliminates the need for external lubrication and reduces maintenance.
  • Durability: The ceramic construction is highly resistant to corrosion and wear, even in the harsh, high-pressure, and high-salinity environment of desalination. The company has certified the PX device with a 30-year design life, building on its reputation for continuous performance and reliability.
  • Impact: By significantly pressurizing the feed water using "waste" energy, the PX device drastically reduces the power requirements for the main high-pressure pump, lowering both the pump's size and the overall power consumption of the plant. Products in this line include the PX Q-Series, such as the PX Q400, which offers the lowest projected life cycle cost of any energy recovery device (ERD) for SWRO desalination.
• AT and LPT Hydraulic Turbochargers:
  • Function: These are fluid-driven turbomachines used for energy recovery. The AT (Axial Turbine) and LPT (Liquid-to-Liquid Pump Turbine) models are often used alongside the PX devices or in other fluid-flow processes to recover energy where high efficiency and flow are required.
• High-Pressure Feed and Circulation Booster Pumps:
  • Function: The company also supplies high-pressure pumps that work in conjunction with its energy recovery devices to complete the fluid-flow system for desalination and water treatment applications.

2. The Emerging Technologies Segment

The Emerging Technologies segment is focused on applying the company's core pressure-exchanger technology and expertise in fluid dynamics to non-water industrial markets. The central theme of this segment is to commercialize pressure energy recovery solutions for the Oil & Gas, chemical processing, and other heavy industrial sectors to enhance operational efficiency and reduce emissions.

Core Emerging Technologies Products

• IsoBoost System:
  • Function: The IsoBoost system is a hydraulic pressure recovery solution designed specifically for use in gas treating and CO2 removal systems, which are common in Gas Processing Plants, Ammonia Plants, and Liquefied Natural Gas (LNG) facilities.
  • Mechanism and Impact: Similar to the PX device, it incorporates a liquid-to-liquid turbocharger that recovers pressure energy from a high-pressure fluid letdown???such as rich amine???and transfers that energy to an adjacent, low-pressure fluid stream???such as lean amine???to boost its pressure. This pre-pressurization significantly reduces the power demand on the main high-pressure circulation pump. The IsoBoost system can save plants up to 50% of electric power operating costs for the high-pressure pump and improve the plant's Environmental, Social, and Governance (ESG) profile through reduced power usage and CO2 offset.
  • System Integration: The technology is often integrated in parallel or in series with electric motor-driven pumps, utilizing the captured energy to reduce the electric motor horsepower required for the overall pumping system.
• IsoGen System (Related Technology):
  • The IsoGen system represents a variant of the pressure recovery technology, engineered to convert the recovered hydraulic energy into useful shaft power that can then be used to generate electricity (hence 'Gen' for generator) or drive other mechanical equipment, offering a different modality of energy savings to the industrial user.

In summary, Energy Recovery Inc. serves as a critical enabler of clean and efficient fluid-flow processes. Its expertise lies in its proprietary, maintenance-light, and ultra-high-efficiency PX technology and its derivatives, which are primarily focused on drastically lowering the energy and cost burden of water desalination and industrial fluid processing.
