Shallow Sand Filters for Circulating Water Systems

Introduction

For 16 years, LEFILTER has been a trusted manufacturer of high-quality filtration solutions, specializing in cost-effective shallow sand filters for industrial applications. Based in Xinxiang, Henan Province, China, our factory-direct production model allows us to offer superior quality at competitive prices with fast lead times. Our shallow sand filters have become the filtration system of choice for industrial circulating water applications across various sectors.

The Critical Need for Effective Circulating Water Filtration

Industrial processes that rely on circulating water systems - including cooling towers, rolling mills, continuous casting machines, and other manufacturing equipment - face constant challenges from suspended solids, scale, and other contaminants. These impurities can cause:

1. Reduced heat transfer efficiency in cooling systems

2. Increased wear and corrosion of equipment

3. Clogging of spray nozzles and heat exchangers

4. Higher energy consumption

5. Increased downtime for maintenance and cleaning

LEFILTER shallow sand filters provide an efficient, economical solution to these problems, maintaining water quality and protecting valuable industrial equipment.

LEFILTER Shallow Sand Filter Advantages for Industrial Applications

1. Superior Filtration Performance

Our shallow sand filters effectively remove suspended solids down to 10-20 microns, with customizable options for finer filtration when needed. The multi-layer filtration media ensures optimal particle removal while maintaining excellent flow rates.

2. High Flow Capacity

The unique shallow bed design allows for higher flow rates compared to conventional sand filters, making our systems ideal for large-volume industrial circulating water applications.

3. Compact, Space-Saving Design

With their low-profile construction, LEFILTER filters require significantly less space than traditional deep bed sand filters - a crucial advantage for industrial plants where floor space is often limited.

4. Automated Operation

Our systems feature automatic backwashing capabilities with minimal water consumption, ensuring continuous operation without manual intervention - critical for 24/7 industrial processes.

5. Durable Construction

Built with heavy-duty materials suitable for industrial environments, our filters withstand high pressures and challenging operating conditions.

Key Industrial Applications

1. Cooling Tower Water Filtration

Protect heat exchangers, condenser tubes, and cooling tower fill from scaling and fouling. Our filters maintain heat transfer efficiency and reduce chemical treatment requirements.

2. Rolling Mill and Continuous Casting Systems

Remove scale, metal oxides, and other particulates from cooling water in steel processing equipment, extending component life and maintaining process consistency.

3. General Process Water Filtration

Provide clean water for various manufacturing processes where water quality directly impacts product quality and equipment performance.
