Advanced Solutions for Clean Water
GreensandPlus™ Filtration Media for Water Treatment: Effective Solution to Remove Iron, Manganese, Hydrogen Sulfide, Arsenic, and Radium
Watermart supplies GreensandPlus™ Inversand in Indonesia for iron, manganese, H2S, arsenic, and radium filtration in well water, industrial raw water, and RO pretreatment. PT Watermart Perkasa, operating at water.co.id, is an Indonesian water-treatment component supplier; the Watermart team helps match media selection with water analysis, flow rate, tank size, backwash capacity, and supporting components such as automatic valves, cartridge filters, dosing pumps, and RO membranes.
GreensandPlus™ uses a manganese dioxide-coated surface with a silica sand core. It can replace manganese greensand in many existing filters, but selection still depends on pH, Fe, Mn, H2S, oxidant strategy, and available backwash rate. For complete systems, GreensandPlus™ is commonly paired with Pentair automatic filters and control valves, Fleck, Autotrol, FRP tanks, pretreatment before Reverse Osmosis, and DIONIX ion exchange resin when ion polishing is required.
When To Choose GreensandPlus™
| Buyer question | Practical answer | Related page |
|---|---|---|
| The well water has iron, manganese, or H2S odor | GreensandPlus™ can be used as oxidation-filtration media when pH, oxidant, and backwash conditions are suitable. | Iron removal system |
| RO membranes foul because of Fe/Mn | Use iron/manganese removal media before cartridge filtration and RO membranes. | RO membranes and cartridge housing |
| The filter needs automatic backwash | Pair the media with a tank and valve that can meet the required service flow and backwash rate. | Pentair automatic filters |
| The final target is demineralization or ion polishing | GreensandPlus™ handles Fe/Mn in pretreatment; resin handles dissolved ions in the next stage. | DIONIX ion exchange resin |
Buyer Application Targets
- well water with high iron and manganese
- industrial filtration pretreatment before RO
- H2S odor removal from raw water
- manganese greensand replacement in existing filters
- automatic filter systems with scheduled backwash
- municipal, food and beverage, hotel, hospital, and industrial utility installations
What is GreensandPlus™?
GreensandPlus™ is a black granular filter media specifically developed to remove a variety of contaminants in a single filtration process. This media can be used in vertical/horizontal pressure filters and gravity filters, and can replace manganese greensand without the need for equipment modification or complicated preconditioning.
Key Advantages of GreensandPlus™
- Multi-Contaminant Removal: Effectively removes iron, manganese, hydrogen sulfide, arsenic, and radium all at once.
- High Durability: The silica sand core withstands severe operating conditions, high TDS levels, and low silica environments without degrading.
- Optimized Performance: Resistant to differential pressure and high temperatures, allowing longer operating times between backwashes.
- Easy Integration: Can directly replace manganese greensand without equipment changes.
- NSF/ANSI 61 Certified: Safe for drinking water applications and proven in installations around the world.

GreensandPlus™ FAQ
Does Watermart supply GreensandPlus™ in Indonesia?
Yes. PT Watermart Perkasa supplies GreensandPlus™ through water.co.id for industrial, commercial, utility, and RO pretreatment projects in Indonesia. Stock availability, lead time, and technical requirements are confirmed based on project size.
What data is needed to select GreensandPlus™?
Send raw-water test results, especially Fe, Mn, H2S, pH, turbidity, TDS, flow rate, operating hours, tank diameter, and final water-quality target. These inputs determine oxidation needs, bed depth, service flow, and backwash design.
Can GreensandPlus™ be used before RO membranes?
Yes, when the raw-water problem is iron, manganese, or H2S that could foul membranes. After media filtration, an RO system usually still needs cartridge filtration, pressure and flow monitoring, and chemical dosing when water quality requires it.
Is GreensandPlus™ the same as ion exchange resin?
No. GreensandPlus™ is filtration media for Fe/Mn/H2S oxidation and removal, while ion exchange resin such as DIONIX is used for hardness removal, demineralization, mixed bed polishing, or dissolved-ion control.
