Got gray water on board? We keep filtration modules and 3-stage systems ready so you can treat in real time and avoid holding tanks or pump outs. Just ask.
Gray Water Filter Features
The GrayWaterFilter (GWF) is designed for the commercial marine industry to treat your gray water and simply filter out and remove: soaps, shampoos, dish and laundry soaps, body oils, makeup, shaving cream, toothpaste, BOD’s, phosphates, and nitrates from gray water prior to overboard discharge.
01
Design
- Module or system: Furnished by itself for integration or as a modular 3 stage filtration system with pump and strainer
- Multi-media approach: Uses several different filter medias and a unique flow pattern to remove gray water pollutants
- Prefiltration: Required to get the most life from the module
02
PERFORMANCE
- Targeted removal: Soaps, shampoos, dish and laundry soaps, body oils, makeup, shaving cream, toothpaste, BOD’s, phosphates, and nitrates
- Capacity option: Module shown can treat up to 5300 gallons of gray water
- Real-time treatment: Eliminates the need for on board holding tanks or costly pump outs
03
COMPLIANCE
- Standards-driven: Designed to meet 91/271/EEC and MARPOL Annex IV as criteria for water acceptable to discharge
- Vessel regulations context: Addresses gray water within changing Vessel General Permit requirements and varying coastal and Great Lakes restrictions
04
OPERATIONS
- Gray water realities: Typical contents include cleaning materials, hair and lint; holding tanks become foul smelling and contain bacteria
- Alternative history: Electric powered evaporators used for ZERO LIQUID DISCHARGE, but soaps cause foaming and sudsing
WHY GRAYWATERFILTER MATTERS
Gray water is high-volume and regulation-sensitive. This module treats pollutants in real time using multiple medias and a unique flow pattern, targeting discharge criteria without relying on holding tanks or pump outs.
The Challenge: Power Plant Ash Pond Dewatering
The GrayWaterFilter (GWF) is designed for the commercial marine industry to treat your gray water and simply filter out and remove: Soaps, shampoos, dish and laundry soaps, body oils, makeup, shaving cream, toothpaste, BOD’s, phosphates, and nitrates from gray water prior to overboard discharge.
The GrayWaterFilter module can be furnished by itself to incorporate into your existing system or as a modular system including 3 stage filtration system with pump and strainer. Prefiltration is required to get the most life from the GRAYWATERFILTER module.
Got Gray Water? Got Vessel General Permit?
The GWF module uses several different filter medias and the unique flow pattern to remove the gray water pollutants prior to discharge. The GrayWaterFilter was designed to meet the tough EU waste water treatment (91/271/EEC) and MARPOL Annex IV as the criteria for water acceptable to discharge. We don’t play by those rules here in the USA just YET!
Historically for gray water disposal we have used our BilgeVAP and MarineVAP electric powered evaporators on-board the vessels for ZERO LIQUID DISCHARGE. But even with the evaporators——the soaps cause a great deal of trouble with foaming and sudsing getting out of control.
Typically gray water consists of: soaps and shampoos, hair conditioners, lotions and gels, greases, oils and cosmetics, cleaning materials, hair and lint. If Gray water is collected and retained in a holding tank, it becomes foul smelling and contains bacteria, some of which are dangerous. Using gray water holding tanks takes space and adds weight resulting in greater power requirements and emissions. So what’s in Gray Water?
A key requirement of successful gray water treatment is the ability to process the water in real time. With the GrayWaterFilter the need for on board holding tanks or costly pump outs is eliminated.
Regulations, Capacity & Treatment Approaches
Here in the USA the commercial marine industry is losing their exemption to the Vessel General Permit (VGP) which is a set of regulations governing how several waste streams generated aboard vessels—-can be handled. Chief among these wastewater streams is gray water, since there are relatively huge volumes to deal with from showers, hand washing, dish and laundry soaps.
The commercial marine industry working on the Great Lakes has a more severe set of restrictions than do the boats working the moving waters on the inland rivers. Coastal operators also often have a different set of regulations depending on how the states or even the ports regulate gray water treatment or disposal.
Frequently Asked Questions
What pollutants does the system remove from gray water?
It removes soaps, shampoos, dish and laundry soaps, body oils, makeup, shaving cream, toothpaste, BOD’s, phosphates, and nitrates prior to overboard discharge.
Can the module be integrated into an existing setup?
Yes, it can be furnished by itself to incorporate into your existing system or as a modular system including a 3 stage filtration system with pump and strainer.
Is prefiltration needed?
Yes, prefiltration is required to get the most life from the module.
What standards was the system designed to meet?
It was designed to meet EU waste water treatment (91/271/EEC) and MARPOL Annex IV as the criteria for water acceptable to discharge.
How does real-time treatment help onboard operations?
With real-time processing the need for on board holding tanks or costly pump outs is eliminated.
