KFM Activated Media Filter: Advanced Oil-Containing Wastewater Treatment Solution

1. Introduction to KFM Activated Media Filter

The KFM Activated Media Filter by SINOKLE is a precision filtration device based on ultra-hydrophilic modified activated filter media. It combines both physical interception and surface adsorption functions, making it ideal for the deep treatment of oil-containing, polymer-containing, and suspended solid wastewater. It is an optimal choice for scenarios like oilfield reinjection water and power plant oily wastewater. The filter can reliably control the effluent oil content to ≤6mg/L and suspended solids to ≤2mg/L. The filter media has a service life of up to 15 years, excellent corrosion resistance, and can operate for extended periods in environments with a pH range of 1-12. The modular design reduces the footprint by approximately 30%.

2. KFM Activated Media Filter Process Principle

The ultra-hydrophilic modified activated filter media has an extremely strong hydrophilicity. Water rapidly spreads on its surface and passes through the filter media pores smoothly, forming a stable hydrophilic coating film. When oil-contaminated wastewater flows through the filter media layer, the water phase is driven by the ultra-hydrophilic surface, allowing it to pass through the filter media while hydrophobic emulsified oil droplets are intercepted and adsorbed on the filter media surface. Over time, they accumulate, and under hydraulic pressure, they collide and coalesce, forming larger oil droplets that eventually rise, achieving separation from the oil phase. The modified active filter media surface usually has a rich micro-nano pore structure, which enhances the stability of the hydrophilic membrane and increases the contact area between the emulsified oil droplets and the filter media. This facilitates easier interception, coalescence, and aggregation of the oil droplets into larger ones after collision.

4. Outstanding Features of KFM Activated Filter Media Filter

· Exceptional Corrosion Resistance

The core activated filter media of this filter is made from high-purity quartz (SiO2 content ≥ 99.9%), which is virtually inert to acids and alkalis, offering superior corrosion resistance compared to conventional filter media (quartz sand, silicate-based filters, garnet, anthracite coal, etc.).

· Resistance to Extremely High Chloride Ion Concentrations

Quartz, with its covalent bond network structure, is not susceptible to chloride ion corrosion, with no risk of pitting or stress corrosion cracking.

· Chemical Stability & Low Leaching Risk

High-purity quartz does not release ions in various solutions, preventing pitting caused by insufficient chemical stability of the filter media. The filter media undergoes acid washing treatment before leaving the factory to ensure it does not release ions.

· Mechanical Strength & Longevity

High-purity quartz filter media has high hardness (Mohs hardness of 7) and shows no aging issues at 80°C, ensuring long-term stable operation.

· High Filtration Precision

The ultra-hydrophilic modified activated filter media forms a hydrophilic water film with a micro-nano structure on its surface, significantly improving filtration precision (with over 99% efficiency for particles ≥1 μm). It effectively captures fine oil droplets and suspended particles in water, ensuring high filtration accuracy. The precision can reach micron or sub-micron levels, suitable for high-quality oil-water separation applications, such as in the renewable energy industry, oil fields, and refining industries. KFM activated filter media provides fine filtration at the terminal, ensuring that the effluent oil content is ≤5mg/L, meeting stringent reinjection standards.

· Corrosion-Resistant, Adaptability

The main equipment uses carbon steel with internal corrosion protection, while core equipment and flow parts are made from high-end materials like 316L stainless steel. This ensures excellent resistance to high chloride and high salinity environments, guaranteeing long-term stable system operation.

· High Recovery Value, Economical Operation

The filtration process is purely physical separation, with recovered oil having low water content and high quality, suitable for direct reuse. The system features high automation, low energy consumption, and reduced maintenance costs, leading to significant overall economic benefits.

· Modular Skid Design, Quick Deployment

The device is integrated and skid-mounted, with a compact structure that facilitates transportation and on-site installation. It is particularly well-suited for oilfield sites with limited space and expansion needs, significantly shortening the construction period.
