High Flow Shallow Sand Filter-LEFILTERWATER

Introduction

The shallow sand filter is composed of one or more standard high-speed sand filter units, with unique water distributor and water collector inside. It adopts a special automatic flushing valve to realize sequential backwashing of multiple standard high-speed sand filter units during normal system operation, with fully automatic program control. It features low backwash water consumption, easy installation and operation, large flow rate and no maintenance required. Vertical and horizontal series are available to meet water treatment needs in various fields. It is applied in power, reverse osmosis pre-treatment, petrochemical, fine chemical, food and beverage, agricultural irrigation, automotive, industrial, metallurgical, paper, pharmaceutical, microelectronic and environmental water treatment industries, filtering water suspended solids, particles, scale, algae and rust.

Working Principle

Composed of several filter units, the system distributes water evenly through a unique water distributor when in filtration state. Water flows through the filter material layer (precision uniform quartz sand) in laminar flow, with impurities intercepted in the filter layer. Multiple evenly distributed water collectors at the bottom collect and discharge the filtered water, enabling high-speed filtration with good effect.

Features

High filtration speed and low pressure loss, solving the problems of slow speed and small flow of ordinary mechanical media filters.
Modular design with small footprint (over 40% reduction) and less piping engineering (over 50% reduction).
Manual, semi-automatic and fully automatic backwash options to meet different needs.
Flexible backwash water source: system water, water tower or external water source, with automatic switching available.

Advantages

Imported core components: Reliable imported valves and control units ensure stable and efficient operation.
Single-chamber design: Better backwash effect and lower sand loss rate, reducing maintenance costs.
Durable water collector: Stainless steel or ABS material ensures long service life.
Convenient maintenance: Bottom outlet pipe reduces water resistance and simplifies inspection.

Application

Power industry: Pre-filtration of power plant water systems.
Reverse osmosis pre-treatment: Protection of RO membranes from sediment and particles.
Petrochemical and fine chemical industry: Filtration of process water and chemical reagents.
Agricultural irrigation: Filtration of irrigation water to prevent nozzle clogging.
