Shallow Sand Filters: Reliable Pre-Filtration for Industrial Water Applications

Introduction

For over 16 years, LEFILTER has been a trusted manufacturer of high-quality filtration solutions, specializing in shallow sand filters. As a factory-direct supplier based in Xinxiang, Henan Province, China, we offer cost-effective, efficient, and durable filtration systems designed for industrial water pre-filtration.

Our shallow sand filters are widely used in steel plants (oxygen lance water), boilers, heat exchangers, and other industrial water systems to remove suspended solids, prevent pipe and nozzle clogging, and ensure smooth operations. With in-house production, we guarantee competitive pricing, fast lead times, and consistent quality to meet global demand.

Why Choose LEFILTER Shallow Sand Filters?

1. High-Efficiency Filtration for Industrial Water

Industrial water systems, such as those in steel mills, power plants, and chemical processing, require clean water free from sediments and particulates. Our shallow sand filters effectively remove sand, rust, algae, and other suspended solids, protecting downstream equipment like:

Oxygen lances in steelmaking (preventing nozzle blockage)

Boiler feedwater systems (reducing scaling and corrosion)

Heat exchangers (maintaining optimal heat transfer efficiency)

2. Durable & Low-Maintenance Design

Stainless steel or FRP (fiberglass-reinforced plastic) tanks for corrosion resistance

Multi-port valve for easy backwashing and maintenance

High-grade quartz sand media for long-lasting filtration performance

Automatic or manual control options to fit different operational needs

3. Cost-Effective & Fast Delivery

As a direct manufacturer, we eliminate middlemen, offering lower prices without compromising quality. Our streamlined production ensures:

Short lead times (7-15 days for standard models)

Customizable designs (flow rate, tank material, pressure rating)

OEM/ODM support for specialized industrial applications.

Key Applications in Industrial Water Pre-Filtration

1. Steel Plants – Oxygen Lance Water Filtration

In steel manufacturing, oxygen lances inject high-purity oxygen into furnaces. Contaminated water can clog nozzles, reduce efficiency, and damage equipment. Our shallow sand filters:

Remove iron oxides, scale, and particulates from cooling water

Ensure uninterrupted oxygen lance operation

Extend equipment lifespan

2. Boiler Feedwater Treatment

Impurities in boiler water can cause:

Scaling (reducing heat transfer)

Corrosion (leading to pipe failures)

Increased energy consumption

LEFILTER’s sand filters pre-treat feedwater, protecting boilers from:

Silt, sand, and organic matter

Suspended colloids

Iron and manganese deposits

3. Heat Exchanger Protection

Heat exchangers rely on clean water for efficient thermal transfer. Our filters:

Prevent fouling and clogging in tubes

Reduce downtime and maintenance costs

Improve overall system efficiency
