MATALA Biofilter 10 - User Manual

Matala Biofilter 10 Installation and maintenance manual
Matala Biofilter 10 is suitable where you have a small
water consumption of max 400 l/day and 55 l/h.
If you have several wires out of the house, it can be led
to the same filter, or you could place a filter in each
place. It is also available as a model with a built-in
pump, to pump away the water after the filter.
Matala grey water filter/BDT (bath, dishes & laundry)
is the original and it has sold in the thousands over
the past 15 years.
• No costs for consumption
• No electricity consumption
• No moving parts
Matala grey water filters are adapted for smaller amounts of BDT wastewater such as in
small houses, holiday homes, sauna houses, building sheds and others where you do not
have water connected.
Not all types of grey water filters can handle high flows that you can have in year-round
houses with high water consumption, then choose other technology.
The capacity is from 400 to 750 liters/day, depending on the model and accessories.
Biofilter 10 has a capacity of 400 l/day or 55 l/h and Biofilter 20 & 25 can handle 750 l/day
and 75 l/h.
Function
The function is completely natural by purifying the water, as it slowly flows through the
patented filters that break down biological nutrients with Biofilm technology with microbes.
Since the filters are airy in the biofilter and the water varies in level all the time, no air
compressor is needed for oxygenation of the biohud.
There is always some water at the bottom of the biofilter so that the biohud should always
have a good environment even when the load stops.

Summary

Biofilter Functionality

Biofilter Installation

Inlet Grey Water Connection

Connect grey water to the short side with a single 75mm inlet hole.

Outlet Water Connection

Purified water connects to the lower hole with two 75mm outlets.

Emissions and Disposal

Purified Water Disposal Options

Release purified water into stone coffin or HS infiltration systems.

Infiltration System Setup

Spreader tube in biomodule, covered with ground cloth and gravel.

Handling Difficult Soil Conditions

Expand area and add drainage pipes for difficult soil absorption.

System Enhancements

Leveling Tank Accessory

An accessory to manage warm water temperature affecting the biohud.

Parallel Filter Connection

Connect two filters in parallel to increase capacity to 600 litres/day.

Pumping System

Pump Connector Details

Includes a 32mm PEM connector suitable for 32mm PEM hose.

Pump Pressure Curve

Technical graph showing pump head versus flow rate.

Ventilation System

Outgoing Air Path

Outgoing air exits via housing pipe trunk or lid hole, ideally high.

Ventilation Importance

Emphasizes ventilation for air exchange and biodegradation at both ends.

Maintenance and Cleaning

Factors Affecting Biofilter Function

Microbial growth is sensitive to poisoning from chemicals, detergents, oil, etc.

Greasy Dishwater Management

Large amounts of greasy dishwater may require more frequent filter cleaning.

Filter Element Cleaning Indicator

Deteriorated flow or dirty upper parts indicate cleaning is needed.

Filter Element Arrangement

Filters are arranged: 2 green, 2 blue, and 4 grey from inlet to outlet.

Filter Element Cleaning Procedure

Clean filter elements annually by shaking them over a compost.

Residual Sludge Disposal

Residual sludge should be composted in a latrine compost.

Filter Cleaning Procedures

Filter Cleaning Method

Shake off 90% of sludge from filters over compost; return filters to ensure purification.

Sludge Composting Duration

Compost sludge in a latrine compost for 6 months for full degradation.

Caution Against Over-Cleaning

Avoid frequent cleaning as it reduces microbial growth and purification results.

Winter Operation and Freezing

Drain biofilter if freezing risk stops flow; insulate extra for winter use.
