Pretreatment is a critical and decisive stage in any water and wastewater treatment train. Suboptimal performance at this stage disrupts downstream core systems—such as membrane processes, Advanced Oxidation Processes (AOP), ozonation, and biological treatment—resulting in reduced efficiency, increased cleaning frequency, fouling, and higher operation and maintenance costs. Leveraging two decades of in-house engineering experience, OzonAb delivers a comprehensive, engineered portfolio of pretreatment equipment for municipal and industrial applications, ensuring stable influent quality to sensitive downstream stages in full compliance with applicable standards.

Key Benefits:

• Protection and extended service life of high-value equipment (membrane systems, ozone generators, AOP reactors)
• Effective reduction of key pollution parameters (TSS, COD) prior to the main treatment units
• Modular designs adaptable to flow rate, fluid composition, and site space constraints
• Reliable performance under Iran’s diverse climatic conditions
• Fabrication using durable, corrosion-resistant materials (stainless steel, FRP) with high resistance to impact and hydraulic shock

OzonAb Pretreatment Products:

• Screen & Grit Remover: First line of defense for removing coarse solids and sand particles; equipped with an automatic washing system and constructed from stainless steel.
• Micro Strainer: Removal of fine suspended particles smaller than 100 microns with efficiencies up to 90%, utilizing a rotating stainless-steel screen and an automatic backwash system.
• Sand, Activated Carbon, and Cartridge Filters: Designed for the removal of suspended solids, organic matter, chlorine, odor, color, and particles down to 1 micron; custom-engineered in FRP, carbon steel, or stainless-steel housings.
• Drum Filter: An optimized solution for continuous flows with moderate to high pollutant loads, particularly suited to industries such as aquaculture and food processing.
• Air and Oil Filters: Protection of sensitive compressed-air equipment, ozone generators, and injection pumps by removing particulates, moisture, and oil vapor.

The OzonAb Advantage:

• Custom design and manufacturing based on precise influent fluid analysis
• Integration of in-house engineering expertise with international design standards
• 18-month warranty and long-term after-sales service
• Integrated technical support for combined systems encompassing pretreatment, ozone, AOP, and membranes
