Middlesex, NJ, July 14, 2025 – Sigma Design Company, a leader in the development of patented and innovative water conditioning components, filters, and systems, introduces the Sigma Industrial Water Group and adds two new systems that expand its portfolio of water and wastewater treatment product and solutions. This capability, which builds on more than 25 years of work in the water and wastewater sector, provides clients with fully customizable, engineered solutions for industrial water and nonhazardous wastewater challenges.
The Sigma Industrial Water Group specializes in the development of systems and technologies for industrial water reuse and recovery, separation and filtration, desalination pretreatment, ultraviolet (UV) disinfection, and the reduction of wastewater TSS discharge. The group builds all of its products to spec, ensuring that new systems meet each client’s unique requirements, and if it is building a component destined to be part of a bespoke water system, the group ensures that it can be integrated smoothly into the existing line.
The new systems are:
The Model 4613 Automatic Tubular Backwash Filter Systemwith 1-to-1500-micron Filter Elements, designed specifically to filter particulates from the fluid stream. Each filter housing contains a filter element with multiple tubes. To achieve finer filtration levels, each tube can be fitted with a 1-micron (1μ) up to 200-micron polymer filter sleeve. Multiplex units consist of anywhere from 2-20 individual tubular filters piped and valved in parallel to common inlet, outlet, and drain headers. Sigma’s advanced control system includes motor control and protection circuitry and constantly monitors the flow rate and different pressures across the entire system.
The Model 4614 UV + Automatic Prefilter Process Water System,which couples Sigma Industrial Water Group’s patented automatic water filtration technology with UV disinfection, a chemical-free water treatment process that uses ultraviolet (UV) light to kill or inactivate harmful microorganisms, including bacteria, viruses, and protozoa. It provides a highly effective, environmentally friendly, and easy to use solution for treating and disinfecting water in a wide range of applications and industries. Examples of applications include wastewater treatment and industrial water reuse and makeup water, while industries range from aquaculture to pharmaceutical production, electronics manufacturing, food & beverage, and other industrial markets.
In addition to these two new systems, the Sigma Industrial Water Group has also developed these recent advancements that comprise part of the company’s suite of solutions:
Model 4583 High Solids Separation and Water Recovery System, which helps maintain peak efficiency and reduce downtime in industrial water processing challenges presented by heavily loaded water systems and the difficulties in managing high solids content
Model 4615Automated Industrial Backwash Filter Control System, a package that ensures that water filtration processes run smoothly, efficiently, and reliably,and its Differential Pressure (DP) Alarm Panel, a simple, easy-to-install, and configured solution to monitor the pressure drop across a filtration media or other pressure-sensitive processes. It is suitable for liquid and gas process systems. Using its HMI Touch Screen, the user can easily monitor inlet/outlet pressure on a continuously updating display with 0.1 PSI accuracy both locally and remote; dynamically adjust the DP alarm setpoint; and monitor the current DP up to 20 PSID.
A wealth of experience and expertise
With more than 25 years of work in the water industry, Sigma Design Company’s vast experience ranges from the development of filtration devices and media selection for solid/liquid separation, to flow analysis and modeling, industrial filtration systems and water treatment systems, filter component design and commercialization, filter housings (ASME VIII), and more. Focused on clients looking for water systems-related solutions, the company and its Industrial Water Group deliver cost-efficient, innovative, and highly effective designs and assembly solutions that meet each client’s unique business goals and leverage Sigma’s outside-the-box thinking. Its team of experienced filtration engineers provides expertise in filtration separation solutions and understands process limitations. Using advanced design tools and 3D visualization of fluid flow profiles, the company is able to uncover and remedy non-obvious, counter-intuitive design flaws.

New Jersey-based Sigma Design is a leading one-stop design, engineering, and manufacturing resource for the development of specialty equipment and engineered systems. Our clients have included hundreds of leading global brands and manufacturing firms across a wide array of industries, transforming more than 1,000 design and design/build projects into successful products and specialty equipment in use across the world.
Testing and validating product is of paramount importance no matter what industry you are in, and this often requires specialized equipment and processes. When it comes to industrial lubricants, it is critical to ensure that these products will provide the advertised level of protection for the equipment to which they will be applied.
Viscosity is a key metric specifically for lubricants, which is defined as a measure of a fluid’s resistance to deformation at a given rate. In simple terms, viscosity is a fluid’s “thickness”.
This can get complicated when it comes to lubricants in high friction applications such as an automotive engine or a turbine spindle. As heat rises due to friction, a lubricant’s viscosity, and thus its wear protection, will decrease. Knowing how effective your grease will be at room temperature and in operation is critical for manufacturers and consumers alike.
Sigma Design recently developed a lubricant test machine for a global petroleum company, one of our valued customers, to measure changes in viscosity of grease over a several hour-long trial. This rotating equipment is loaded with large, greased bearings and spun at several hundred RPM. The equipment is designed to measure the resistance of the grease between a driven top-half and idler bottom-half of the bearing chamber. The resulting force is displayed on a simple and reliable analog gauge that can be viewed and logged throughout the test. Our equipment provides a simple solution to a crucial need.
Sigma Design has developed and built analytical, testing and validation equipment for dozens of our customers across a wide variety of industries. From consumer product testing to cellular research, Sigma Design has been a valued and trusted manufacturing partner of equipment for over 20 years.
Customer: Free Flow Power, MA Industry: Alternative Energy Sub Heading: Sigma Design Develops a State of the Art, Run of River, Hydrokinetic Electric Generator.
Hydrokinetic River Turbines Capture Alternative Energy.
Sigma was approached by a Boston venture group who needed to develop a pilot renewable energy hydrokinetic generator system. It was a pivotal milestone for the ventures funding and they needed this fully submerged run of river device in the water and producing electrical energy in 6 months from our first meeting. In addition to the accelerated timeline, the project provided us with several other challenges. Most notably being the power generating electronics, hydrodynamic balancing, and marine submersion anti-fouling prevention. In the end we were successful in that the system was designed, manufactured and installed. In fact we understand that it is still running deep in the Mississippi River north of New Orleans.

Sigma Design supports U.S. Navy shipboard defense systems
Sigma was very excited to work on another project with the U.S. Navy. Talk about a project in ‘our wheelhouse’ as they say. Jerry Lynch, a ‘tin can sailor’ who served as a destroyer GMG2 gunner was thrilled to have the opportunity to work on this special project supporting shipboard defense systems for Navy operations.
Michael Collins, the lead engineer on the NAVSEA project worked for the U.S. Navy in Philadelphia before coming to Sigma. This project requires the creative design of safety features while providing 50% more power through their hydraulic power supply system. With operating pressures in excess of 3000 psi, the pressure compensation and hydraulic shock suppression systems were key features in the new design. This HPU joins the growing roster of Sigma’s products designed and built in NJ. Sigma is proud to have the opportunity to work with the Navy to improve operational shipboard defense systems used around the globe but made in NJ.
Services Performed System engineering, detail design, CAD drafting, electronics, welding services, machining and fabrication, testing & start-up, system training, and on-site validation.
