Water Treatment & Technologies

Pretreatment Filtration

Pretreatment filtration is vital to most water purification systems and removes contaminants that can affect final water quality or downstream treatment processes. Pretreatment equipment includes multi-media turbidity filters that remove particulates and other suspended solids to approximately 25 microns; 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 particulates. These filtration components can be used separately to address specific site treatment requirements or designed into water purification systems to eliminate premature fouling of reverse osmosis membranes and to minimize interference with the ion exchange process.

Reverse Osmosis

Hydro is an original equipment manufacturer (OEM) for reverse osmosis (RO) systems. RO is suitable for a variety of applications and manufacturing processes and commonly used as pretreatment for other downstream purification components. RO extends the capacity of service deionization by as much as ten times. Hydro’s RO systems consist of self-contained cabinets and small open frame units for lighter production, and skidded units for heavier production. Systems are custom fabricated and equipped with instrumentation to monitor water quality, membrane efficiency, flows and pressures. Membrane selection is based upon production needs and feed water quality. Systems are available with production rates from 0.5 to over 500 GPM with average salt rejections up to 99%.


There are two primary options to achieve deionization. Service Deionization (SDI) utilizes regenerable mixed-bed (cation/anion) resins with chemically bonded positive and negative charges. In the ion exchange process, the cation resins release hydrogen ions and the anion release hydroxyl ions. These ions bond creating a pure water molecule. Hydro’s service DI resins are recycled and regenerated in a manner complying with use in pharmaceutical application. Our superior regeneration process and methods typically yield higher resistivity with lower TOC (Total Organic Carbon) re-introduction. 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 water molecules to split into hydrogen (H+) and hydroxyl (OH-) ions. These ions attach to the cation and anion resin respectively, creating continuous regeneration while simultaneously deionizing the water. Contaminant ions are forced into a reject stream. EDI can be a cost effective alternative to service mixed-bed ion exchange.


Storage tanks are used to contain high purity water or act as capacity buffers, eliminating the need for oversized reverse osmosis systems that feed directly into processes. Storage tanks must preserve the integrity of the water. Materials of construction include stainless steel, fiberglass reinforced plastic (FRP), or premium grade medium density plastics. The tank manufacturing process must adhere to quality standards for use with high purity water. Stainless steel tanks are available as atmospheric or pressure rated vessels with varied interior and exterior finishes. Stainless steel is also the material of choice for hot water applications such as water for injection (WFI) production in pharmaceutical processes. Tanks constructed of other materials are atmospheric and usually vented with sub-micron filters. Storage tanks are sized according to the demand of the water system or application.


Without compromising quality, 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 upon the application, alternating controls for duplex pumps, variable frequency drives (VFD’s) and soft-starts can be implemented into your custom distribution skid.

Post Treatment

Post treatment components heat, cool and further enhance the purity of water. This equipment is usually skid-mounted and consists of bacteria destruct and/or TOC reducing ultraviolet (UV) sterilizers, submicron microbial-controlling post filtration, and heating or cooling exchangers.

Control Panels & Instrumentation

PLC control panels can be simple or complex depending upon the application and client requirements. Control panels can be utilized for system automation and include programmable logic controllers (PLC’s), interfaces, signaling devices, power regulating controls, timers and relays, protection devices and switches. Software and programming are offered as well. All panels and control features are custom designed specific to the project (usually with expansion capabilities) and can integrate with management networks if required. All panels are manufactured in Hydro’s UL 508 panel shop with complete documentation and drawing packages available. 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 critical product manufacturing. Hydro incorporates name-brand reliable instruments and transmitting devices to monitor resistivity/conductivity, pH, pressure, temperature, flows, levels, ozone, total organic carbons (TOC) and more.

Sanitization & CIP

Hydro offers multiple cleaning and sanitization options. For stainless steel, the preference is heat or ozone. Ozone is an excellent choice as well for compatible plastics such as PVDF. Heat and ozone are typically part of the system’s design, with integrated controls for automated operation. Chemical cleaning is an alternative for materials not compatible with heat and ozone. Hydro offers portable chemical and ozone carts for manual sanitizations and custom carts/skids for CIP applications.


Piping used for transporting high purity water must receive equal quality considerations. Suitable materials include polypropylene (PP), polyvinylidene fluoride (PVDF), polyethylene (PE) and stainless steel (SS) and should not re-contaminate purified water. Plastics can be joined by various methods including the popular beadless and seamless weld method used in many pharmaceutical and electronic grade water systems. Orbital welding is preferred for stainless steel. 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.



POU Laboratory Systems

It all began for Hydro with a brand of laboratory polishers called Picosystems®. These systems have endured time. Today, nine point-of-use (POU) polishers for varying applications are available, and 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 protocols with complete QC/QA. These resins deliver higher purities more consistently and are one of Hydro's green products since they are regenerated and reused. The chassis for all systems is the Picosystem®, delivering ASTM/CAP Type I water using pre-filtration, carbon adsorption, and mixed-bed deionization. The Plus Pump and UV Plus Pump stations provide constant recirculation and TOC reduction, respectively. For applications requiring sterile water, the Picotech® with UV is recommended. The Picopure® and Picomax® deliver sterile, pyrogen-free and RNase-free water. All systems are modular in design so that upgrading from the Picosystem® to the Picopure® UV Plus or Picomax® can occur with ease. These systems are Hydro OEM products made in the USA.



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.



Reclamation & Grey Water Systems

Hydro installed its first Grey Water/Rainwater Collection System in 2002. With the ever increasing awareness of more green, eco-friendly construction and today's demands on natural resources such as water, Hydro has become a solution provider for systems that reclaim water. Target waters such as condensate and reject from purification processes and rainwater run-off can be used for grey water, irrigation, and other processes in new construction projects. These systems usually consist of filtration, chlorination, dying, distribution and controls. Hydro is an excellent source for design assistance as well as the custom fabrication, installation and service of the treatment, controls, and skidded portions of these systems.
