Biolan Light Greywater Filter’s design is based on mechanical and biological filtration of wastewater. Waste water travels through the media and suspended solids are removed. Micro organisms living in the media break the contaminants down in the presence of oxygen. Water flows through the trays of media in series purifying the water.

The greywater filter can deal with a small amount of antibacterial chlorine based cleaning products.

Installing the filter

Place the greywater filter on a firm and even surface that is not susceptible to frost, such as, a bed of gravel or crushed stone or a cast concrete slab. The filter must be in a horizontal position both lengthwise and laterally to allow the wastewater flow smoothly and take advantage of the entire cleaning surface area of the filter material.

Connecting the pipesseries

While installing gravity flow sewers, a sufficient gradient (of at least 1-1,5 %) needs to be provided to allow the greywater to flow without obstruction from the house all the way to the discharge point. To use four units split the flow into two and place two in series on each line.

Putting the filter material in place

The filter material has been placed ready on the trays inside the unit. For transportation it is packed in plastic bags. Remove the plastic bags.
  1. Rip the filter material loose and spread it evenly across the box by tapping it gently. Biolan Light Filter ChangeDepending on the packing method applied there may be excess filter material in the bag. The amount of filter material in the box is sufficient when its surface of the filter media lies about 2 cm below the rim of the tray.
  2. Finally, draw the filter material about 5 cm to the rear from the V-openings in the discharge end of the box.
  3. The filter material boxes are identical, but observe their direction – remember that the water cascades from one box to the next making its way to the outlet.
