Multi Medium Walnut Shell Filter for Oil Industry

Introduction:

In modern industry and daily life, water purification is a crucial task. Walnut shell filters, as an efficient filtering device, have been widely used in many fields due to their unique advantages and performance. This article will provide a detailed introduction to the working principle, structural characteristics, application areas, and advantages of walnut shell filters.

working principle:

Walnut shell filters mainly use walnut shells as filtering media to remove impurities and pollutants from water through physical filtration and adsorption.

When the water to be treated enters the filter, it first passes through the coarse filter layer to remove impurities of larger particles. Then, the water flows through the walnut shell filter layer, and the micropores and rough structure on the surface of the walnut shell can effectively adsorb pollutants such as suspended solids, organic matter, and oils in the water. At the same time, due to the low density of walnut shells, a certain porosity will be formed under the action of water flow, allowing the water flow to pass evenly through the filter layer and improve the filtration efficiency.

After being processed by the walnut shell filtration layer, the water is further filtered through the fine filtration layer to remove residual small particles and impurities, ultimately resulting in clean water flowing out of the filter.

technical parameter:

The technical parameters of walnut shell filters include working pressure, working temperature, filtration speed, operating cycle, backwashing method, backwashing water consumption, backwashing intensity, etc. ‌

Work pressure: ≤ 0.6MPa

Working temperature: 5~60 ℃

Filtration speed: 20-25m/h

Operating cycle: 8-24h

Backwash method: Water backwash

Backwash water consumption: 1-3%

Backwash strength: 4~15l/s · m ²

Structural characteristics:

1. Tank structure

Walnut shell filters typically consist of a tank body, inlet and outlet ports, water distribution system, water collection system, backwash system, and other components. The tank body is generally made of materials such as carbon steel and stainless steel, which have sufficient strength and corrosion resistance. There are multiple filtration chambers inside the tank, each separated by partitions to ensure uniform distribution of water flow and filtration effect.

2. Filter media

Walnut shell, as a filtering medium, has the characteristics of high hardness, wear resistance, and good adsorption performance. The particle size of walnut shells can be selected according to different filtration requirements, generally between 0.8-1.2mm. In order to improve filtration efficiency, walnut shells are usually subjected to special treatments such as cleaning, disinfection, activation, etc.

3. Water distribution system

The function of the water distribution system is to evenly distribute the water to be treated onto the filter layer to ensure the uniformity of the filtration effect. The water distribution system generally consists of water distribution pipes, nozzles, etc. Multiple nozzles are installed on the water distribution pipes, which can spray water onto the filter layer at a certain angle and speed, so that the water flow can pass through the filter layer evenly.

4. Water collection system

The function of the water collection system is to collect filtered water and discharge it out of the filter. A water collection system generally consists of a collection pipe, a collection device, etc. The collection pipe is equipped with multiple collection holes, which can collect filtered water and discharge it from the filter through the collection device.

5. Backwash system

The function of the backwash system is to backwash the filter medium after a period of operation, in order to remove impurities and pollutants adsorbed on the filter medium and restore its filtration performance. The backwash system generally consists of a backwash pump, backwash pipeline, control valve, etc. The backwash pump can provide sufficient pressure and flow to transport backwash water to the inside of the filter through the backwash pipeline, backwashing the filter medium.

application area :

1. Oilfield wastewater treatment

During the development of oil fields, a large amount of oily wastewater is generated. Walnut shell filters can effectively remove pollutants such as oil, suspended solids, and organic matter from oily wastewater, improve the reuse rate of wastewater, and reduce environmental pollution.

2. Industrial wastewater treatment

Walnut shell filters can be used to treat various industrial wastewater, such as papermaking wastewater, printing and dyeing wastewater, chemical wastewater, etc. It can remove pollutants such as suspended solids, organic matter, and chromaticity from wastewater, meeting national discharge standards.

3. Drinking water treatment

In drinking water treatment, walnut shell filters can be used as pre-treatment equipment to remove suspended solids, organic matter, iron, manganese and other pollutants from water, improving the quality of drinking water.

4. Swimming pool water treatment

Swimming pool water contains a large amount of suspended solids, organic matter, bacteria and other pollutants. Walnut shell filters can effectively remove these pollutants and maintain the cleanliness and hygiene of swimming pool water.

advantage

1. Good filtering effect

Walnut shell filters can effectively remove pollutants such as suspended solids, organic matter, and oils from water, with good filtration efficiency and stable effluent quality.

2. Wear resistance

Walnut shell, as a filtering medium, has the characteristics of high hardness and wear resistance, and can maintain good filtering performance during long-term operation.

3. Strong adsorption performance

The micropores and rough structure on the surface of walnut shells can effectively adsorb organic matter, oil and other pollutants in water, improving filtration efficiency.

4. Easy backwashing

The backwash system of walnut shell filter is easy to operate, has good backwash effect, and can quickly restore the filtration performance of the filter medium.

5. Low cost

Walnut shells, as a natural filtering medium, are inexpensive and widely available, reducing the cost of filters.

Conclusion:

Walnut shell filters, as an efficient, economical, and practical filtration device, have been widely used in fields such as oilfield wastewater treatment, industrial wastewater treatment, drinking water treatment, and swimming pool water treatment. It has the advantages of good filtration effect, wear resistance, strong adsorption performance, convenient backwashing, and low cost, providing an effective solution to solve water pollution problems. When using walnut shell filters, attention should be paid to installation, operation, backwashing, and other aspects to ensure the normal operation and filtration effect of the filter. With the continuous advancement of technology and people's emphasis on environmental protection, walnut shell filters will be applied and developed in more fields.
