Pretreatment filtration includes Multi-Media Turbidity Filters that remove particulates and other suspended solids; Carbon Filters that remove chlorine, chloramines and organics; Water Softeners that remove hardness ions; filters that remove iron; and bag or cartridge filters that remove more nominal or absolute micron-sized particles.  These filtration components can be used separately to address specific site treatment requirements or designed into water purification systems to eliminate premature fouling of RO membranes or to minimize interference with ion exchange or other downstream purity processes.

Reverse Osmosis (RO)

Reverse Osmosis removes 90-99% of dissolved inorganics, 99% of organics larger than 200 molecular weight, particles to 0.001 microns and most microbial contamination.  RO water is suitable for a variety of applications and processes and is commonly used to extend the capacity of deionization and, as pretreatment for other downstream purification components.  Skids can be custom fabricated and equipped with any level of instrumentation and controls.  Membrane selection is based upon production needs and feed water quality. Hydro is an original equipment manufacturer (OEM) for reverse osmosis (RO) systems.

SERVICE Deionization (SDI)

Service Deionization (SDI) utilizes regenerable mixed-bed (cation/anion) resins. In the exchange process, the cation resins release hydrogen ions and the anion release hydroxyl ions. These ions bond creating a pure water molecule (HOH). Hydro’s SDI resins are recycled and regenerated in a proprietary method and process which typically yield higher resistivity, lower TOC (Total Organic Carbon) re-introduction and maximum throughput before resin exhaustion.

Electrodeionization (EDI)

Electrodeionization (EDI) is a continuously regenerating, low maintenance process utilizing cells containing ion exchange resins and membranes. DC electrical current is applied to the cell, causing a portion of the water molecules to split into hydrogen (H+) and hydroxyl (OH-) ions. The H+ and OH- attach to the cation and anion resin respectively creating continuous regeneration while simultaneously deionizing water and forcing contaminant ions to a reject stream. EDI can be a cost-effective alternative to service, mixed-bed ion exchange.


Storage vessels for high purity water act as capacity buffers, eliminating the need for oversized reverse osmosis systems that feed directly into processes.  These vessels must preserve the integrity of the water therefore, superior materials of construction including stainless steel, fiberglass reinforced plastic (FRP) or premium grade medium density plastics should be chosen.  The manufacturing process must adhere to quality standards for use in high purity applications.  Stainless steel vessels are available as atmospheric, or pressure rated with varied interior and exterior finishes.  Stainless steel is the material of choice for heated applications such as pharmaceutical processes.  Vessels constructed of other materials are atmospheric and usually vented with sub-micron filtration.  Storage Vessels are sized according to the demand of the water system or application. The distribution, recirculation, and pressurization of pure water is dependent upon reliable, heavy-duty pumps rated for continuous use.  Internal pump components such as shafts, impellers, rotating assemblies, and casings are stainless steel with NEMA standard motors direct coupled to the pump shaft for true alignment.  Depending on the application, alternating controls for the duplex pumps, variable frequency drives (VFDs), and soft-starts can be implemented into a custom distribution skid. Post treatment components heat, cool, and further enhance water purity. These components are usually skid-mounted and consists of bacteria destruct and/or TOC reducing ultraviolet (UV) sterilizers, submicron microbial-controlling post filtration, heating or cooling exchangers, ultra-filters and a variety of instrumentation for monitoring water quality.




Piping distributing high purity water must receive equal quality considerations.  Suitable materials include stainless steel (SS) typically used in pharma/biotech/food & beverage and heated applications, polyvinylidene fluoride (PVDF) also in pharma/biotech and microelectronics,  polypropylene (PP) and polyethylene (PE) in most other applications. These materials should not re-contaminate purified water.  Orbital welding is typical for stainless steel and plastics polymers can be joined by various methods including the popular beadles and seamless weld method used in many pharmaceutical and microelectronic water systems.  .  All techniques require certified, experienced personnel adhering to strict installation guidelines.  Stainless steel will require cleaning and passivation, and plastic piping should be flushed and sanitized.  Sanitization methods must be material compatible.

Instrumentation & Controls

Instrumentation & Controls can be simple or complex depending on the application and user requirements. Control are utilized for system automation and include programmable logic controllers (PLC’s), interfaces, signaling devices, power regulation, timers, relays, protection devices and switches. Software and programming are offered and any instrumentation & control features are custom designed specific to a project (usually with expansion capabilities).  Integration with management networks are typical and all panels are manufactured in Hydro’s UL 508 panel shop with complete documentation and drawing packages. Instrumentation for operational and quality monitoring is vital to almost every water system. More sophisticated and regulated applications often require a higher degree of instrumentation and data collection to monitor proper operations, verify purity levels and track all aspects of water generation for critical manufacturing. Hydro incorporates the industries best and most reliable instruments and transmitting devices to monitor quality and operation and, panel components based on individualized project requirements of operation.


Reclamation/Reuse Systems

There is an ever-increasing awareness of more green, eco-friendly construction and today’s demands on natural resources such as water.  Hydro is very experienced at solutions for systems that reclaim and reuse waters such as condensate, reject from purification processes, rainwater that can be used for grey water and irrigation and microelectronics cleanrooms. Hydro has earned a reputation of being an excellent source for design assistance as well as custom fabrication, installation, and service of the treatment, controls, and skidded portions of these systems.

Picosystems® – It all began for Hydro with a brand of laboratory polishers called Picosystems®.  Today, nine point-of-use (POU) polishers for varying applications are available, all are industry leaders in quality comparisons to other POU systems.  Purity begins with quality materials and components such as activated carbon for maximum organic reduction and premium DI resins regenerated under proprietary.

Picotap Laboratory Faucets – Picotap® faucets were originally introduced to complement Hydro’s POU Picosystems®.  These faucets are made of ultra-high molecular weight polypropylene and polyethylene plastics without sealants and glues.  Unlike other materials, these plastics will not re-contaminate highly aggressive purified water.  The patented non-particulating diaphragm valve effectively meters water while minimizing microbial growth.  Picotap® faucets are easy to install and an excellent choice to accompany new laboratory POU water systems or casework having purified water plumbed within.  Picotap® faucets are a Hydro OEM product made in the USA and available for next day shipment to any destination.
