Durable Pumping and Mixing Solutions

Landia, first and last in biogas plants Powerful mixers and pumps with a unique cutter system ensure excellent chopping and mixing in the pre-treatment tank. A homogeneous substrate is crucial to a fast anaerobic process and maximum gas production. For pasteurisation, Landia offers a patented, stand alone and fully automated unit for treatment of Category 3 by-products. Landia offers three different types of equipment for anaerobic digester and post digester mixing. Great emphasis is placed on mixing systems that can be maintained from the outside without costly, complicated and risky...

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 homogeneous substrate without any harsh or large pieces of dry matter is of crucial importance to the subsequent anaerobic digestion process. Landia offers highly efficient propeller mixers and chopper pumps for this application. Anaerobic digester...

GasMix™ systems are ideally applied for homogenizing anaerobic digester contents. Significant advantages compared to conventional digester mixing 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. ©Significantly improved health and safety conditions due to external installation. Reduced capital cost: no access walkways, platforms or hoists required. Enhanced cell break down resulting in increased biogas production. Unique 3-dimensional mixing...

Chopper Pumps – The unique concept Landia Pumps with chopping system – the answer to all pumping applications in biogas plants. The chopping 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. The pump casing, impeller and sealing system will not be worn or damaged in connection with the chopping process. Back plate and front plate with guide traces The hard wearing chopping system is made of hardened steel; long lasting and easy to replace. Open...

Propeller Mixers The Landia 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 efficient long lasting solutions in liquids with high solids/dry matter content. Landia propeller mixers are equipped with a unique triple shaft sealing system as a dependable protection of gearbox and motor in liquids with high solids/dry matter content. A special outer seal against the surrounding liquid ensures that stringy and long fibrous materials from...
