Description

                                                                       Shallow Sand Filter

 

Equipment Overview: shallow sand filter system is composed of a plurality of standard high-speed sand-cylinder units, which features a unique water distribution and catchment, has a unique way automatic flush valve, can be realized in the normal operation of the system and more standard high-speed sand cylinder individually separate backwash, automatic process control. Backwash water with a small, easy installation, easy operation and so on. The device flow, no maintenance. Depending on the user requirements, with two series of vertical and horizontal. Suitable for industrial and commercial water treatment circulating water system.

Working principle
For the by-pass filtration, the filter is installed in the main circulating pipeline to filter all the circulating water, but a part of the circulating water LED from the main circulating pipeline is filtered, which is a repeated circulating interception step by step to filter the impurities within the system and finally remove the impurities by the necessary backwash out of the system. Installing a by-pass filter in the circulating water system can prevent the terminal pipe of device from sludge blocking and remove the impurities in the system with chemical dosing.
By-pass filtration is used to reduce the turbidity of the water circulation system, exactly, to reduce slime and prevent its deposition in the heat exchanger, so that the effect of agent will be better.

Generally speaking, if your filter is a quartz sand filter, it usually has two main functions:
1. To reduce suspended solids (turbidity). Otherwise, as the system is running, suspended solids increases, which will exacerbate the deposition and other problems.
2. Degreasing. Especially the oily turbid circulation, such as steel rolling and continuous casting, has high oil content and is easy for breeding microorganism and blocking the nozzles.

Technical description of by-pass filter for the industrial circulating water
Flow filter flow is designed according to 5% to 10% of the total circulation volume (the by-pass filter flow of the cooling water is designed by 10 % of the circulation volume and the by-pass filter flow of chilled water is designed by 5% of the circulation volume) and the filtration rate is designed by 20 — 3Smih according to water quality of the system. Specific to corrosive suspended solids of the circulating water system as well as the control, our technical support team has designed a variety of manual/automatic by-pass filtrating equipment in line with customer demand.

 

Shallow Filter is an innovative, sand thickness of only 40 mm, the spherical shell and unique interior design to ensure smooth flow filter, filter effects form the inner turbulence; backwash efficiency is high, time is short, backwash consumption the amount of water is about 30% of the traditional sand filters. Changed the traditional sand filters, valveless backwash waste water, backwash incomplete, bulky, rookie of the media filter industry.

 

Product Features:

 

Shallow filter filtration system uses a modular design, based on traffic, covering, etc., can be flexibly combined. The system can be used, pressure a variety of ways to start automatically backwash, fully automatic operation. Each filter unit in the system sequentially backwashing is not interrupted when the backwash effluent.

 

Automatic control of the filtration system is modular in design, according to the size of the flow, a plurality of filter units.

 

Can be used, pressure, etc. a variety of ways to start automatically backwash the filter unit in the system are backwashed, the other unit is still in the filter.

 

The high recoil efficiency, recoil a short time, the backwash water conservation (backwash water consumption rate is less than 1%).

 

Small footprint, and the flexibility to design the arrangement of the filter unit according to the actual land.

 

The system is lightweight and does not require special base concrete floor can.

 

All-plastic system, good corrosion resistance.

 

ASM filter, has a better resistance to bacterial contamination, the backwash better.

 

Shallow filters system is lightweight and does not require an ad hoc basis, a general concrete floor system covers an area of small, flexible arrangement according to the actual situation, easy to install.

 

The shallow filter filtration system can be applied to a variety of water treatment industry, such as water supply and filtration treatment, cooling circulating water filter and next to the filter, wastewater treatment and reuse, and so on, is an alternative to traditional sand filters, valveless preferred.
