2.Petrochemical Solutions
Chemical Filtration: Anda filtration products deliver the highest quality while significantly reducing production costs for chemical processing. Our tailored solutions-including depth filters, pleated cartridges, and high-flow filters-are engineered to meet precise customer requirements, ensuring optimal performance and cost efficiency.
Oil & Gas Filtration: Membrane filters for oil and gas applications must meet exceptionally high standards. Crude oil and natural gas often contain mixtures of hydrocarbons, water vapor, acidic gases, and other contaminants that require rigorous purification. Our advanced filtration systems ensure reliable removal of impurities, protecting downstream equipment and maintaining process integrity.
Amine Sweetening: During amine sweetening (H₂S/CO₂ removal), reactive byproducts such as solid particulates, heat-stable salts, sulfides, and iron fines can accumulate-leading to foaming, scaling, and reduced efficiency. High-performance filters from Anda effectively capture iron sulfide, rust, and liquid contaminants, safeguarding system longevity and operational stability.
Injection Well Water Filtration: Injection wells maintain reservoir pressure to enhance oil recovery, demanding water quality that meets strict geological standards. Our water treatment systems and premium filters (e.g., 5-micron pleated high-flow cartridges or wound honeycomb filters) are the proven choice for eliminating particulates and ensuring compatibility with reservoir conditions.
Completion & Workover Fluids Filtration: Completion fluids (used during well construction) and workover fluids (for well maintenance) must be meticulously filtered to prevent reservoir clogging. These fluids remove drill cuttings, mud, cement residues, and sand while ensuring clean fluid recirculation. Our filters excel at trapping contaminants, allowing only purified fluids to re-enter the well-maximizing productivity and minimizing downtime.
- Precision Engineered: Solutions backed by 20+ years of industry expertise.
- Trusted Performance: Filters designed for harsh petrochemical environments.
- Cost-Smart: Reduce operational expenses while extending equipment life.

5.Water Treatment Solutions
Process Water
For producing high-purity water, a multi-stage filtration system is employed. This includes pre-RO filters, ventilation filters for water tanks, pre-filters to prevent contaminants, activated carbon, and ion exchange resin beds, followed by final membrane filtration to ensure the highest water quality.
Condensate Water
Essential in protecting boilers, steam generators, reactors, and turbines from corrosion, specialized filters are used. These include deep-wound cartridge filters for demineralizers, self-cleaning pleated filters for pre-filtration, and high-flow filters to safeguard the deep bed layers, ensuring long-lasting system performance.
Drinking Water System
This system focuses on removing impurities and harmful substances from residential and commercial drinking water to ensure safety. A 5-micron deep filter is used to capture sand, sediments, and particulate matter, while ultra-filtration membranes or RO membranes are protected. High-end sintered carbon filters effectively adsorb residual chlorine, lead, heavy metals, and improve taste and odor.
Seawater Desalination
Microfiltration serves as an essential pre-treatment for reverse osmosis in seawater desalination, removing impurities, reducing chlorine levels, and protecting the RO membranes to prolong their service life. Additionally, absolute-rated pleated filters are widely used in various end-stage filtration applications, providing efficient, safe, and reliable filtration.
Wastewater Treatment
Wastewater must be treated to be safely recycled, reused, or discharged into surface water or municipal sewage systems. Deep filters are used to remove solid contaminants, dyes, chemicals, heavy metals, and organic matter, ensuring treated water meets regulatory standards for disposal or reuse.
RO Pre-Filtration
Given that reverse osmosis membranes have a pore size of just 0.0001 microns and are expensive, there is no straightforward method for removing particles entering the RO membrane. Therefore, pre-filters like deep filters and pleated cartridges are used as a highly effective solution to protect the RO membranes and extend their lifespan.
