System Operation

Designed for Drip Irrigation

The Flotender Greywater Filter has been specifically designed to prepare greywater to meet the purity demands required for use in a drip irrigation system. Dual-stage filtration consists of 150 mesh (100 micron) primary filtration followed by 140 mesh (105 micron) secondary filter. Greywater passing through Flotender's advanced filtration conforms to virtually every commercial drip irrigation manufacturers' filtration specifications.

Automated Operation

The Flotender™ Greywater Filter is fully automated. When greywater enters the system it is automatically filtered, pressurized, and pumped to the above ground or subsurface drip irrigation system. When the water drops to the designated minimum pumping level the system shuts off until the next inflow of greywater.

Advanced Debris Sealing

In order for a drip irrigation system to work properly, the water being used must be completely free of even the smallest particulates. The Flotender Greywater Filter incorporates a series of ultra-tight gaskets and seals to prevent particulates from passing around the filter.


Greywater Filter Pump


Other systems (typically priced under $1,000) provide filtration but don't completely seal off the pump chamber. This can result in debris slipping around the filter and ultimately ending up in the drip line. Once debris enters the drip irrigation system removal can next to impossible and often times requires a complete system removal and reinstallation.

Visual Indication of System Status

Performance indicators pop-up when the system is pumping and pressurized. The tan indicator signals that the pump is running. The green indicator signals that the secondary filter is operating and the drip system is pressurized.

One Concept, Three Series

Each of Flotender’s three series of Greywater Filters contain the same components: the Access Cap, Filter Baskets, Bolt Down Lid, Filter Carriage, Spray Ring, High Pressure Pump, Pump Switch and the Polyethylene Housing. Certain specifications vary by model, but the mechanics and engineering remain constant. Precise greywater filtration, expandable surge capacity, automated operation and high pressure pumping are just a few of the many design and installation advantages unique to the Flotender Greywater Filter.

High Pressure Pumping

Whether the filtered greywater is to be used to water plants on a flat area, a terraced garden, or to irrigate a lawn via sub-surface irrigation, the built-in Flotender pump is fully capable of transporting the water where you need it. Refer to the pump curve below for specific detail on the pumping capabilities of the Flotender Greywater Filter.

Supplemental Fresh Water

The auto-flush device adds additional freshwater to the Flotender Greywater Filter in situations where insufficient greywater is produced to adequately irrigate the landscape. Simply design the drip irrigation system, and schedule the irrigation controller to add occasional fresh water to the greywater zone as needed. For larger landscapes with limited greywater sources, greywater is used to offset normal evaporation, while fresh water is used to provide an occasional deep watering.

Greywater Autofill

Primary Filter

The Flotender's Primary Filter catches all debris from the inflowing greywater through 150 mesh (100 micron) filtration. The Automatic Backwash System prevent fine particulate from sticking to the filter mesh.

Secondary Filter

The secondary filter provides a second level of filtration to the Flotender System before the greywater water reaches the drip system. It protects against micro lint that may clump together after passing through the filter basket, or any surface debris that could possibly drop into the pumping chamber after removing the filter basket.

Greywater Additional Filtration


Greywater Secondary Filter

The stainless steel filter support system allows multiple filters to be connected in parallel for high flow or heavy lint loading.







Adding Additional Surge Capacity

Incorporated into each Flotender Greywater Filter is a specific amount of surge capacity. If more surge capacity is required to accommodate a large number of greywater producing fixtures, additional capacity can be easily installed at either the time of the initial installation, or post installation.

Maintenance Reduced With Automatic Backwash System

The Flotender's patent pending self regulating backwash system prevents lint and other greywater debris from collecting on the inside of the filter basket. The high pressure rotary spray nozzles are mounted on a flotation assembly which allows for constant cleaning at fluctuating water levels. The Backwash system is activated as soon as greywater enters the system and continues to operate until the greywater is pumped out.
