Shallow sand filter is the sand cylinder unit consists of one or more standard, it has unique water distribution and water collection, has a unique automatic flush valve, which can realize multiple standards high in normal system operation sand cylinder one by one single back flush, automatic process control.Backwash water consumption is low, installation is simple, operation is simple, and so on; the equipment has a high flow rate and requires no maintenance. There are vertical and horizontal two series, which are suited for the water quality in the field of numerous processing requirements, depending on the user requirements.

The operating principle

Filtration status:

Filtering conditionShallow sand filter made up of numerous parallel filtering units. When the system is in filter mode, unfiltered water flows through their own unique cloth water heater consistent water distribution, and water flows through the filter packing layer (refined grains of quartz sand). Impurities trapped within the packing layer when water flows through it. Have more than one set of uniform distribution of water at the bottom of the filter to collect and raise the filtered water equitably, advection, filter, may make filter under high velocity and still achieve better filtering effect.
Status of backwashing:
Backwashing conditionHead loss will continue to rise inside the contaminants that build in the packing layer over time. When there is a value into and out of the water head loss, the system will automatically activate the constant pressure difference devices to make its transformation to the state of backwashing, and when backwashing is complete, change the direction of the water hydraulic valve so that impurities of build-up can be cleaned more easily.When the system is in a backwashing condition, the filter continues to operate, which is standard for backwashing to the unit sand cylinder, which is not filtered, other standards in the system unit sand cylinder is still in the filter. A portion of the clean water is filtered and used to wash the standard unit sand cylinder; the remainder is returned to the user.
Backwash wastewater is ejected by the backwashing hydraulic valve drain. At high speeds, the effective filtration system between the sand cylinder and the specific header design can make the packing filler rub against one other and enhance flushing efficiency while reducing backwashing water (clean water) at the same time when the backwashing phenomena does not occur.
Standard unit sand cylinder backwashing for 3 minutes, reverse wash over, standard unit sand inside cylinder head loss to reasonable scope, constant pressure device recovery signals are given to filter state hydraulic valve, next standard unit sand cylinder and prepared to enter a backwashing state, system can be controlled by control backwashing, default 4 hours backwashing time, adjust time, dual system according to scene working conditions Primary and secondary control, with first come, first served.intenance.

Applications
Electricity, reverse osmosis pre-treatment, petrochemical, chemical, food and beverage, agricultural irrigation, automobiles, T industry, metallurgy, papermaking, pharmaceutical, microelectronics, environmental protection water treatment, and other industries.

Characteristics of Shallow Sand Filter
Various installation methods are available for units ranging in size from 24 inches (500 mm) to 96 inches (2400 mm). Filter can be used as an independent system, in addition to the existing process for water pump, if it is used as a filter, it can also be equipped with its own pump. Filters can also be many processing units deployed in public so that this system filtering capacity can be implemented. Backwashing filter system can be started manually, semi-automatically, or fully automatically by a manual button, PLC, pressure difference, or management system. Backwashing cycle and time length are configurable; the factory setting is 3 minutes. PLC control is used to implement an automatic filtering control system.
1. high filtering speed, low pressure loss, entirely solves the slow, small flow problem of conventional mechanical medium filters.
2. modular setting, cover an area of an area small, pipe, less capital investment. The area covered is reduced by more than 40%, and the piping quantity is lowered by more than 50%.
3. Manual, semi-automatic, and automatic backwashing are available to meet your specific requirements.
4. Optional backwashing water system, water tower, or external water sources, with the ability to switch automatically (specific needs).
5. Multiple cell combinations can be processed in any order.
6. The shell and pipe are composed of Q235B carbon steel, but stainless steel can also be used.
7. Imported main components (BERMAD, BACCARA, SIEMEN, MITSUBISHI).
8. The filtering unit is designed with a single cavity for easier backwashing and a lower run sand rate.
9.Siamese stainless steel/ABS material for prolonged life.
10.outlet pipe installed in the unit's bottom, water resistance, smaller, more convenient maintenance.

The benefit of a shallow sand filter
Efficient
The essential components are imported in their original packaging (BERMAD, BACCARASIEMENMITSUBISHI).
Flexible
The filter unit has a single chamber design, which improves backwashing and reduces sand flowing rate.
Reliable
For a longer service life, the water collector can be made of stainless steel or ABS.
Stable
The water outflow pipe is located at the bottom of the unit, resulting in reduced water resistance and easier maintenance.
