Water Treatment Filters

Water treatment filters are among the key equipment used in water purification and pretreatment processes. Depending on the filtration technology and media used, these systems can remove suspended solids, turbidity, sludge, chlorine, unpleasant odors, color, organic compounds, and other contaminants from water.

The appropriate filter type, capacity, vessel material, and filtration media should be selected based on raw water analysis, required flow rate, operating conditions, and required product water quality.

Mojan provides a range of water treatment filters and filtration equipment for industrial, commercial, building, and water and wastewater treatment applications, with solutions designed according to the specific requirements of each project.

Types of Water Treatment Filters

Sand Filter

Sand filters are widely used to remove suspended solids, turbidity, sludge, and particulate matter from water. They are commonly installed as one of the main pretreatment stages in water treatment systems and Reverse Osmosis (RO) plants.

Mojan sand filters are designed according to the required flow rate, feed water quality, and project conditions. They can be used in industrial water treatment systems, potable water applications, and as pretreatment for RO systems.

Key Features

• Effective removal of suspended solids and turbidity
• Suitable filtration performance for a wide range of applications
• Durable and robust construction
• Backwash capability for filter cleaning
• Available in different capacities and configurations
• Suitable for water treatment and RO pretreatment systems

Activated Carbon Filter

Activated Carbon Filters use specially selected activated carbon media to reduce free chlorine, unpleasant odors, undesirable taste, color, and certain organic compounds present in water.

They are particularly important in RO pretreatment systems because free chlorine can damage certain types of RO membranes. By reducing chlorine and other contaminants before the RO stage, activated carbon filtration helps protect downstream equipment and improve overall system performance.

Key Functions

• Reduction of free chlorine
• Reduction of unpleasant taste and odor
• Reduction of certain organic compounds
• Improvement of feed water quality
• Protection of downstream equipment
• Protection of sensitive RO membranes

Water Filter Selection Criteria

Proper filter selection should be based on the actual characteristics of the feed water and the requirements of the treatment process. Important parameters include:

• Required water flow rate
• Total Suspended Solids (TSS)
• Turbidity
• Total Dissolved Solids (TDS)
• Type and concentration of contaminants
• Operating pressure
• Required product water quality
• Raw water analysis
• Type of downstream treatment system

Based on the water analysis and project conditions, Mojan can recommend the appropriate filtration technology, filter capacity, vessel configuration, and filtration media.

Customized Filtration Solutions by Mojan

There is no single filtration configuration suitable for every water treatment project. Mojan develops and supplies filtration solutions according to the characteristics of the raw water and the specific requirements of each application.

The selection and design process can include the appropriate filter type, vessel size, filtration media, flow rate, operating pressure, backwash requirements, and integration with downstream systems such as RO.
