Question you may concern
Which chemicals are required for regeneration?
Softening uses NaCl. Demineralization uses HCl or H₂SO₄ for cation resin and NaOH for anion resin.
Can ion exchange work with seawater or high-TDS water?
Ion exchange is more suitable for low to moderate TDS water. High-TDS applications often use RO as a primary treatment.
How often should I replace filters and membranes?
Filter and membrane lifespan depends on water quality, usage, and system type. General guidelines:
1. Sediment & Carbon Filters: Replace every 6–12 months.
2. RO Membranes: Replace every 2–3 years, depending on water conditions.
3. UF/NF Membranes: Replace every 1–2 years.
Regular maintenance ensures optimal performance and water quality.
Can AQT provide custom water treatment solutions?
Yes! We specialize in OEM/ODM water treatment solutions and can design custom filtration systems tailored to your business, industry, or brand requirements. Our team can assist with system design, branding, private labeling, and technical support.

Multi-Layer Media Filter (Anthracite & Sand) for Iron & Sediment Removal
Multi-Media Filter (MMF)
Our Multi-Media Filter (MMF) is a highly efficient water filtration system designed to remove suspended solids, turbidity, and other impurities from water. Unlike single-media filters, MMFs use multiple layers of filtration media—such as sand, anthracite, and gravel—each with varying sizes and densities.
This layered structure allows for superior filtration, increased dirt-holding capacity, and longer operational cycles.
Multi-Media Filters are widely used in industrial, municipal, and commercial water treatment applications, serving as a crucial pre-treatment step for processes like reverse osmosis (RO) and ultrafiltration (UF). By ensuring cleaner water and reducing maintenance needs, MMFs enhance the overall efficiency of water treatment systems.
Media Filters for Preliminary Filtration-GSF Series
Introduction to Green Sand Filter (GSF)
Green Sand Filter (GSF) is an effective water filtration system designed to remove iron, manganese, and hydrogen sulfide from water. Utilizing a specially treated green sand media, this filter works through the process of oxidation and adsorption, where impurities are trapped within the filter media, ensuring clean, clear water. Green Sand Filters are widely used in both residential and industrial applications where water contains high levels of iron and other minerals that can cause staining, unpleasant odors, and corrosion. By providing an efficient and cost-effective solution for water purification, Green Sand Filters help protect plumbing systems, appliances, and enhance water quality for various applications.
Custom-Engineered Industrial Activated Carbon Filters for Water Purification
Activated Carbon Filter (ACF)
Our Activated Carbon Filter (ACF) is a highly effective water filtration system designed to remove chlorine, organic compounds, unpleasant odors, and harmful contaminants from water. Utilizing activated carbon’s high adsorption capacity, ACFs efficiently trap and eliminate impurities, improving taste, color, and overall water quality. These filters are widely used in industrial, commercial, and residential applications, serving as a critical pre-treatment step for processes like reverse osmosis (RO) and drinking water purification. With their ability to enhance water safety and meet stringent quality standards, Activated Carbon Filters play a vital role in various water treatment systems.
