Iron hydroxide groundwater arsenic removal filter material

Iron hydroxide groundwater arsenic removal filter materialSY02-P

1、 Introduction

SY02-PIt is an iron-based adsorbent specially developed for arsenic removal in drinking water. This product has a super large specific surface area (BET) of over 300m ²/g, which enables it to quickly and efficiently combine with inorganic arsenic (+3/+5) in water. Its adsorption capacity is more than 5 times higher than traditional adsorbents. Meanwhile,SY02-Pstill haveexcellentAdsorption selectivity, common anions in water, such as Cl^-、SO₄^2-、HCO₃^2-、CO₃^2-、NO₃^-won't pairSY02-PAdsorption of arsenic causes any interference. Under normal circumstances,SY02-PThe adsorption capacity for arsenic in water is 4-14g/kg.

2、 Advantages

High adsorption capacity:SY02-PRegarding arsenic (As) in water³⁺/As⁵⁺）The adsorption capacity can reach4-14 g/kg， The adsorption capacity is more than 5 times that of common adsorbents.

Adapt to high flow rates:Its extremely large specific surface area ensures sufficient contact with arsenic, thereby achieving efficient adsorption effect,SY02-PIt can adapt to operating flow rates of 10-20m/h and quickly adsorb and remove arsenic from water in a short period of time.

Stability performance:Translate into EnglishSY02-PUsed for arsenic removal filters in groundwater, with arsenic penetration concentration set to ≥ 0.01ppm, its adsorption saturation period is generally 2-5 years - within this time rangeSY02-PCan maintain efficient and stable adsorption capacity.

Wide applicability:inThe performance is stable within the range of pH 5-9 and water temperature 5-40 ℃. Capable of adapting to various water quality conditions and maintaining high adsorption capacity even under high salinity.

No need for regeneration:Applied in the field of arsenic removal from drinking water, it can achieve one-time adsorption saturation without regeneration（Replace the filter material directly within 2-5 years. This eliminates the generation of wastewater and waste residue when using SY02-P filter material, reducing equipment and operation costs.

Not changing water quality:Unlike the physical separation of reverse osmosis membranes and the extensive adsorption of ion exchange resins.The mechanism of action of SY02-P adsorbent is physical (electrical)+chemical (reactive) adsorption, with strong selectivity for arsenic. It does not adsorb common ions in water and generally does not change the composition of ions in water.

Easy to use:Just need to deliver a certain amount as requiredFill SY02-P into the filter tank, then backwash and clean the filter material at a certain flow rate to start normal operation. It should be noted that when the pressure difference before and after the arsenic removal filtration system is ≥ 0.05Mpa, a backwash is required to loosen the filter bed. We will quantify the operational process and provide clear indicators, making it easy for even non professionals to operate.

Technical SupportWe can evaluate the project situation and develop relevant design and operational guidance for clients, providing assistance in both product and technology aspects.

High cost-effectiveness:Compared to similar adsorbents,The price of SY02-P is relatively low, and under normal circumstances, the cost per ton of water is about 0.1-0.2 yuan.

3、 Application scenarios

Centralized purification of drinking water in water plants

Groundwater treatment in villages and towns

Process water for arsenic removal

Upgrading and renovating rural drinking water standards

Mine water treatment

Removing arsenic from beverage water and mineral water

Deep adsorption discharge of sewage at the end meets the standard

4、 Usage and maintenance

To ensureWe recommend that users perform necessary pre-treatment and filtration on the water before use to remove solid impurities, reduce suspended solids content, prevent pore blockage, and affect adsorption efficiency, based on the performance of SY02-P arsenic removal filter material. During use, it is advisable to avoid repeatedly loading and unloading the filter material to prevent uneven distribution of the filter bed and bias. When shutting down for a short period of time, the filter material should be disinfected, cleaned, and soaked in clean water; It is recommended to soak the filter material in a certain concentration of sodium hypochlorite or sodium hydroxide solution to prevent bacterial growth and freezing when it is shut down for a long time or when the temperature is below 5 ° C in winter. These simple maintenance measures can ensure the long-term stable operation of the product and provide you with continuous and reliable water purification services.

5、 Storage and expiration date

SY02-P adsorbent should be stored in a cool and dark place to avoid freezing or heating. The storage environment temperature for general filter media is 5-40 ° C, and unused filter media should not be stored for too long, generally not exceeding 2 years. After exceeding the storage period and passing the re inspection, the product can still be used. Reasonable storage conditions can ensure that the performance of the product is not affected and extend its service life.
