Industrial water mechanical quartz sand filter

Product Introduction

Quartz sand filteris a kind of filter using quartz sand as filter material. It can effectively remove the suspended matter in the water, and the colloid, iron, organic matter, pesticides, manganese, bacteria, viruses and other pollutants in the water have obvious removal effect. It has the advantages of small filtration resistance, large specific surface area, strong acid and alkaline resistance, oxidation resistance, PH range of 2-13, good pollution resistance and so on. The unique advantage of quartz sand filter is that it realizes the adaptive operation of the filter by optimizing the design of the filter material and filter. The filter material has a strong adaptability to the concentration of raw water, operating conditions and pre-disposal process. That is, when filtering, the filter bed automatically forms a state of sparse and dense, which is conducive to ensuring the water quality under various operating conditions. When backwashing, the filter material is fully dispersed and the cleaning effect is good. Sand filter has the advantages of fast filtration speed, high filtration accuracy and large sewage interception capacity. Widely used in power, electronics, beverage, tap water, petroleum, chemical, metallurgy, textile, paper, food, swimming pool, municipal engineering and other process water, domestic water, recycling water and wastewater pretreatment field

Technical parameters

1, design filter speed: 8-12 meters/hour when the head loss is about 5 meters, need to backwash regeneration (generally by reading the inlet and outlet pressure difference at 0.05MP).

2, reverse cleaning strength: 10-15L/ s • square meters.

3. Flushing duration: 5-7 minutes

4, inlet water pressure: ≥0.4Mpa backwashing inlet water pressure: ≥0.20Mpa

5. The expansion rate is 25%-50%.

Component parts

(1) Water distribution plate holes, holes and water distribution device welding, can also choose wire buckle connection, convenient for future replacement. And a hole in the leg.

(2) The welding branch pipe of the lower head is mainly used to support the water distribution plate.

(3) The branch pipe passes through the water distribution plate and is welded. Welding of the water cloth plate and the lower head requires double welding on both sides.

(4) coil plate, welding body and lower spotlight.

(5) Weld the head.

(6) Tank body opening: upper manhole (can also be shared with the packing hole), lower manhole (depending on the distance between the lower head and the water distribution plate) discharge hole, air outlet, water inlet and outlet hole.

(7) Install the water refill pipe and cloth the water wire pipe.

(8) Welding tank legs and lifting lugs.

(9) Mirror polishing.

(10) The water pipe outside the welding cylinder.

(11) With tic-tac-toe arrangement, inlet pipe, discharge pipe and outlet pipe, 5 valves to distribute water flow

Selection of filter media

Quartz sand filter and multi-medium filter are widely used in water treatment. Quartz sand filter material is made of natural quartz ore as raw material and processed by crushing, washing and fine screening. It is currently the most widely used in the water treatment industry.

The largest amount of water purification material, no impurities, pressure and wear resistance, high mechanical strength, stable chemical properties, strong pollution interception capacity, high efficiency, long service cycle, suitable for single-layer, double-layer filter, filter and ion exchanger,

All the indicators reached the (CJ/T43-1999) standard. Processed with refined quartz sand, pure white quartz sand, acid treatment agent, ordinary quartz sand, can meet the needs of different users.
