ALKIN ADMF 5000

Automatic Dual Media Filter for High-Volume Pre-Treatment

In any water treatment system, the quality of pre-treatment directly determines the performance and lifespan of everything downstream. The Alkin ADMF 5000 is a fully automatic dual media filter designed to remove suspended solids, turbidity, and sediment before water reaches RO membranes, softeners, or storage tanks. With a flow rate of 5000 liters per hour (LPH), it is ideal for hotels, schools, nursing homes, commercial establishments, and light industries that need reliable, high-volume pre-filtration.

Why Dual Media Filtration Matters

Untreated feed water often carries suspended solids, silt, and turbidity that can quickly clog or damage sensitive downstream equipment such as RO membranes and ion-exchange resins. A dual media filter uses two layers of filtration material — typically anthracite and sand — to trap particles progressively, from coarse to fine, extending the life and efficiency of the entire water treatment system. The Alkin ADMF 5000 addresses this need with automatic, low-maintenance operation built for continuous, high-demand use.

Key Specifications of the Alkin ADMF 5000

Flow Rate

The Alkin ADMF 5000 delivers a maximum and average flow rate of 5000 liters per hour (LPH), making it suitable for large-scale pre-treatment ahead of RO plants, softeners, or storage systems.

Filter Media

The vessel is loaded with a dual-layer bed of anthracite and graded sand, arranged by density to progressively capture coarse and fine suspended particles as water passes through.

Turbidity Reduction

Designed to bring inlet turbidity down to levels suitable for downstream RO membranes and softener resins, effectively reducing suspended solids and sediment load even at higher flow rates.

Automatic Backwash

The ADMF 5000 features automatic, time or differential-pressure initiated backwashing, which cleans the filter bed without manual intervention, restoring filtration efficiency after each cycle.

Valve & Control

Equipped with a multi-port automatic control valve that manages the service, backwash, and rinse cycles automatically, minimizing operator involvement.

Robust Vessel Construction

Built with a durable FRP or MS-lined pressure vessel designed to withstand continuous operation and higher flow rates in commercial and light industrial settings.

Technical Specifications

Technical specifications are subject to change without prior notice due to continuous product improvement.

Why Choose the Alkin ADMF 5000?

The Alkin ADMF 5000 isn't just another pre-filter; it's a critical safeguard for your entire water treatment investment, built for large-scale flow demands. Here's why it stands out:

1. Protects Downstream Equipment

By removing suspended solids and turbidity upfront, the ADMF 5000 helps prevent fouling and premature wear of RO membranes, softener resins, and other sensitive components.

2. Large-Scale Flow Capacity

With a 5000 LPH flow rate, the ADMF 5000 is built to keep pace with larger commercial and light industrial water systems without becoming a bottleneck.

3. Fully Automatic Operation

Automatic backwash cycles mean the filter bed is cleaned and restored without manual supervision, reducing maintenance workload and downtime.

4. Long-Term Cost Savings

Effective pre-treatment reduces the frequency of membrane cleaning and resin replacement further downstream, lowering overall operating costs over time.

Advanced Technology in Alkin ADMF 5000

Progressive Filtration Process

The Alkin ADMF 5000 uses a layered filtration approach designed to maximize particle removal efficiency:

• Anthracite Layer: The upper, coarser layer captures larger suspended particles first, reducing the load on the finer layer below.
• Sand Layer: The denser sand bed beneath captures finer particulate matter, further reducing turbidity.
• Automatic Backwash Cycle: Reverses water flow periodically to lift and flush trapped particles out through the drain, restoring filter bed performance.

Simple, Reliable Control

The automatic multi-port valve manages service, backwash, and rinse cycles without manual switching, ensuring consistent pre-treatment performance with minimal operator input even at higher flow rates.
