Due to the discharge of various industrial and domestic wastewater, we have different water treatment media products to treat and purify water quality to meet different requirements and goals.
A suspended porous carrier made of high-density polyethylene (HDPE) with special patterns on the surface to increase the specific surface area (usually 500-900 ㎡/m ³), with a density close to water (0.96-0.98 g/cm ³), and can move freely with water flow.
Application:
Used for biochemical tanks in sewage treatment plants (such as AO, AAO processes), industrial wastewater treatment (food, pharmaceuticals, etc.), river restoration, etc.
Advantages:
No need for fixed brackets, saving energy consumption;
The biofilm has strong self-renewal ability and resistance to shock loads;
The existing activated sludge system can be upgraded.
Structure:
The center is a plastic rope or fiber bundle, wrapped around a "snowflake shaped" plastic ring or fiber thread to form a three-dimensional mesh structure.
Function:
Microbial attachment growth combines the high specific surface area of soft fillers with the mechanical strength of semi soft fillers.
Application:
Contact oxidation tanks, hydrolysis acidification tanks, biological filtration towers, etc. are particularly suitable for high concentration organic wastewater (such as slaughter, printing and dyeing wastewater).
Material:
Polyester fibers or polyethylene are woven into ropes or strips, with a rough surface that is prone to film sticking.
Advantage:
Vertical suspension installation, suitable for deep pools;
Corrosion resistant, with a lifespan of over 10 years.
Application:
Marine aquaculture water treatment, MBBR process alternatives, and enhanced treatment of artificial wetlands.
It is usually a plastic modular cube (such as PP material) with a honeycomb or corrugated board structure inside, and a porosity of>90%.
Function:
Wastewater flows through the packing layer from top to bottom and comes into contact with air to complete organic matter degradation and nitrification.
Application:
Decentralized sewage treatment in villages and towns, leachate treatment from garbage, and odor biofilters.
Type:
Hydrophilic sponge with an opening rate of ≥ 95%, with adjustable pore size (such as 10-60 PPI).
Advantages:
Capture suspended solids while cultivating anaerobic/aerobic bacteria;
Easy to clean and regenerate, suitable for small integrated equipment.
Application:
Fish and vegetable symbiotic system, rainwater filtration, MBR membrane pretreatment.
Common types:
Micro porous aerator (EPDM membrane, bubble diameter 1-3mm, oxygen utilization rate ≥ 30%);
Cyclone aerator (anti clogging, suitable for high SS wastewater);
Pipe aerator (easy to install, mostly used for industrial wastewater).
Key selection points:
According to the air volume, water depth, and sludge concentration, regular cleaning is required to prevent blockages.
Material:
Stainless steel 316L or ABS engineering plastic, with a gap width of 0.2-0.5mm.
Function:
Installed at the bottom of the filter plate, evenly distribute water/air, and prevent the loss of filter material during backwashing.
Specifications:
Commonly used for V-shaped filters and ion exchange columns, with long and short handles and a flow rate of 1-2m ³/h per unit.
Tips:
Wastewater treatment: MBBR filter meida+combined filler+cyclone aerator;
Deep filtration: Filter nozzle+filter foam;
Compact equipment: bio trickling filter media+spiral cord braided rope filler
