Industrial Water and Filtration Systems

Sigma Design Company has deep experience in designing, engineering, and manufacturing systems for industrial water and filtration. Since 1999, our work within this industry has encompassed filtration devices and media selection for solid/liquid separation, flow analysis and modeling, industrial filtration systems and water treatment systems, filter component design and commercialization, filter housings (ASME VIII), and more.

Our experienced filtration engineers have expertise in filtration separation solutions and understand process limitations. Using advanced design tools and 3D visualization of fluid flow profiles, we are able to uncover and remedy non-obvious, counter-intuitive design flaws.

Learn more about the different types of industrial filtration systems, their benefits, and Sigma Design’s capabilities below. 

Types of Industrial Filtration Systems

There are four main types of industrial filtration systems:

  • Raw Water Treatment Systems: Raw water treatment systems are often used as a means of pre-treatment, which aims to improve the efficiency and performance of a particular application. Raw water treatment protects downstream equipment from fouling, corrosion, scaling, and other forms of wear by removing contaminants from the source water. Examples of contaminants include bacteria, iron, silica/colloidal silica, suspended/colloidal solids, and hardness.
  • Cooling Tower Water Treatment Systems: These types of treatment systems are designed to protect cooling towers from contaminants such as chlorides, iron, and sulfates. The system first adds makeup water to replace what was lost from evaporation and leaks. The solution then goes through several steps of filtration to remove contaminants. A membrane softener or softening resin reduces hardness. The last step involves additional filtration and adding chemicals to remove lingering contaminants.
  • Wastewater Treatment Systems: Wastewater treatment systems are designed to treat wastewater so that it can be reused or discharged as effluent to a municipal treatment facility or the environment. Contaminants in a waste stream can vary greatly. Most systems treat for nitrates, pathogens, phosphates, biochemical oxygen demand (BOD), metals, TDS, TSS, and synthetic chemicals. 

Benefits of Industrial Water Filtration Systems

Reliable industrial water filtration systems offer many advantages:

  • Improved Treatment Efficiency: When used as pre-treatment, industrial water filtration systems can increase the efficiency of downstream equipment by minimizing the concentration of turbidity and suspended solids. When used as polishing, industrial water filtration removes any remaining contaminants following upstream treatments. 
  • Reduction of Suspended Solids: Most industrial water filtration systems are designed to minimize the volume of suspended solids and turbidity found in a source water stream. Filtering is an excellent way to reduce the burden on downstream processing systems. 
  • Reduction of Other Contaminants: Depending on the approach, filtration systems can do more than just minimize suspended particles or turbidity. Additional features may allow filtration systems to remove particulates such as trace metals, volatile chemical compounds, ammonia, manganese, iron, and more. 
  • Reduced Equipment Upkeep: Operating at full efficiency, an industrial filtration system can lighten the load for downstream treatment. By removing most suspended solids and harmful contaminants, downstream equipment will experience less wear. This reduces the equipment’s maintenance needs and saves your facility time and money.
