108TPH Water Filtration FiIter System for Industrial Use

This is a 30 liters per second (30 LPS=108TPH ) water filtration system designed for a Mexican engineering company.

Raw Water Condition

The raw water comes from the backwash discharge of zeolite and activated carbon filters, with a turbidity of 171 NTU. The customer aims to reuse this water for industrial production after proper filtration.

Filtration Target

After treatment, the system will reduce turbidity to below 5 NTU before the water enters the product water tank. If the outlet turbidity is higher than 5 NTU, the flow will automatically be diverted to a reject water tank, ensuring that only qualified water is reused.

Process Flow of Water Filtration System

The 30 LPS filtration system follows a fully automated multistage process designed to reduce turbidity from 171 NTU to below 5 NTU. The complete process flow is as follows:

1. Inlet Water → Backwash Pump

Raw water from the backwash discharge tank is delivered to the system by a dedicated backwash pump, ensuring stable inlet pressure and flow.

2. Automatic Disc Filter (100 Micron)

The water first passes through a 100-micron automatic disc filter, which removes large suspended solids and protects downstream filters from overload.

• Automatic self-cleaning function

• Differential pressure sensor triggers backwash

• Solenoid valves open and close automatically during flushing

3. Zeolite Filter (SUS304)

The pre-filtered water enters the SUS304 zeolite filter, which removes fine suspended solids, turbidity, and colloids.
This stage provides the primary turbidity reduction.

4. Activated Carbon Filters (Two SUS304 Tanks)

After zeolite filtration, the water is processed by two stainless steel activated carbon filters, operating either in series or parallel depending on design.
They remove:

• Organic matter

• Residual odors

• Color

• Fine particles

This stage stabilizes water quality before final polishing.

5. Cartridge Filter (SUS304 Housing)

The final polishing is completed by a cartridge filter, which ensures fine sediment removal and guarantees the outlet turbidity is consistently ≤5 NTU.

6. Outlet Water Quality Check

A turbidity sensor at the final outlet continuously monitors effluent quality.

Automatic Valve of Water Filtration System

The system uses Siemens PLC to control electric or pneumatic valves. Key logic includes:

Normal Filtration Mode

• Inlet valve opens

• Outlet valve opens

• Reject discharge valve remains closed

• Flow is directed into the clean water tank

High Turbidity Mode (Turbidity > 5 NTU)

• PLC automatically closes the product water valve

• Reject water valve opens

• Water is diverted to the unqualified water tank

• Alarm is displayed on the HMI

Main Advantages of Stainless Steel Design

1. Excellent Corrosion Resistance
   No rust, no corrosion, long service life in various water conditions.

2. High Mechanical Strength
   Strong pressure resistance and stable performance under continuous operation.

3. Easy to Clean and Hygienic
   Smooth surface prevents bacteria growth and simplifies maintenance.

4. Good Temperature and Chemical Resistance
   Withstands high temperature, cleaning chemicals, and disinfection without deformation.

5. Long Lifespan & Lower Overall Cost
