Built to last and with an unrivalled back-up service, pumps and mixers made by Landia (established 1933) are designed to handle even the most arduous of wastewater applications. Manufacturers of submersible chopper pumps and mixers for flow creation, anoxic mixing and aeration, Landia has also developed the externally-mounted GasMix digester mixing system for AD/biogas plants, which produces gas faster, yet with significantly less energy and maintenance costs.

Landia's Biochop for preparation and heat treatment of organic by-products

Landia's Heat-processing plant enables environmental and commercial use of animal by-products and waste at biogas plants.

The BioChop adheres to recently introduced European Regulations (17774/2002), which now permit this process, so long as these products have first been heat-treated at 70° C for at least one hour.

This innovative heat-processing plant includes heat jacket, pump, mixing system with stainless steel valves, automatic control and a monitor. With a proven track record in Scandinavia, the Landia BioChop has, for example, been installed at a 500 kW farm biogas plant, where flotation sludge from fish processors and fat and pig skin remnants from snack producers are processed to substrate. If required, the substrate can then be pumped to the fermenter or to the digester or covered slurry tank.

Suitable for Category-3 by-products and waste, Landia's BioChop heat treatment plant is located in the process before the digester and thus serves not only as a heating unit but also as mixing chamber for the products received at the plant.

Typically containing large dry matter particles which need to be chopped, macerated and mixed with liquid, Landia's heat treatment plant is designed to ensure that it can chop and mix the products and pump the substrate to the digester - all by the same pump. No moving parts are in the tank, and maintenance costs are minimal because the only part that needs to be maintained is the pump.
