Reception and pre-mixing tank

In this tank, different liquids e.g. slurry, sewage sludge or manure are mixed with biomass or organic waste such as corn or grass silage, organic food waste, fats, etc. Often, dry biomass is mixed into the liquid. This requires chopping of the biomass and powerful mixing of the dry material into the liquid part. A homogenous substrate without any harsh or large pieces of dry matter is of crucial importance to the following anaerobic digestion process. We offer highly efficient propeller mixers and chopper pumps for this application.

Anaerobic digester and post digester

Anaerobic digester mixing has to be reliable and energy efficient. Our mixing system, GasMix™, meets these demands. No rotating equipment inside the tank, easy maintenance without the need of opening tank cover or entering the tank and without expensive loss of gas production. In very large tanks, side entry mixers model PowerMix™ can be installed.

Storage tank

Our submersible mixers are specifically engineered for mixing of all kinds of slurries and sludges with a high content of dry matter. Applications can be digestate, slurry, sludge from waste water treatment plants and a number of industries. They are well suited to put settled or floating solids back into suspension. Low propeller rotation ensures high efficiency. The propeller design permits clog-free mixing even in liquids containing large amounts of stringy material or rags. Unique triple shaft sealing system for gear and motor protection against the surrounding liquid.

Introduction to BioGas

Advantages of using our chopper pumps on biogas plantsLandia chopper pumps are well suited for all major pumping applications on biogas plants. Built for heavy duty applications where foreign objects often create a severe pumping environment for other pumps, the unique cutter system and open impellers bring a number of advantages:

■ Smaller foreign objects such as grit, sand, small pieces of broken glass can pass through the pump without damaging it and with only minimal wear.

■ Sudden blockage because of larger foreign objects will normally not damage the pump. ■ No need for expensive pre-grinders and macerators. ■ No pressure pulsation in the pipe system.

Anaerobic Digester Mixing System GasMix™

DescriptionGasMix™ systems are ideally applied for homogenizing anaerobic digester contents.

Signifi cant advantages compared to conventional digestermixing systems:

■ No rotating equipment inside the tank ■ Easy maintenance and service without need of

emptying the tank or opening tank covers. ■ No costly loss of gas production during pump

maintenance ■ Signifi cantly improved Health and Safety

conditions due to external installation. ■ Reduced capital cost, no access walkways,

platforms or hoists required. ■ Our chopper pumps enhance cell break down.

Together with gas recirculation, increased methane (CH4) concentration can be achieved.

■ Unique 3-dimensional mixing pattern reduces formation of scum layers.

■ Powerful mixing is achieved by a chopper pump and one or more top gas/sludge ejector nozzles and a bottom mixing nozzle

Rotating and fi xed knives

Chopper pumps

DescriptionThe unique cutter system is clearly separated from the pump casing and the impeller. This prevents blocking of the pump and its subsequent piping as all chopping is completed before it enters the pump housing. Pump casing, impeller and sealing system will not be worn or damaged in connection with the chopping process.

The hard wearing cutter system is made of hardened steel, long lasting and easy to replace.

Large selection of materials and options

All our chopper pumps are equipped with a cutter system of two rotating and one or three fi xed cutters. The pumps are manufactured in cast iron or acid-proof stainless steel.

For abrasive conditions hardened knives, impellers; pump front and back-plate in special materials can be off ered. 2-component painting is optional. Installation equipment is available in several qualities of stainless steel or galvanized mild steel.

Motors are available in diff erent explosionproof versions.

DescriptionOur mixing systems for biogas plants are based on many years of experience in mixing and homogenizing slurries and sludges. An extensive range of mixers with large blades and low propeller rotations ensure energy effi cient long lasting solutions in liquids with high solids content.

Our propeller mixers are equipped with a unique triple shaft sealing system as a dependable protection of gear and motor in liquids with high solids content.

A special outer seal against the surrounding liquid ensures that stringy and long fi brous materials from grass, straw or corn will not damage the mechanical seals in the interior part of the sealing system.
