R.T.S. ROCHEM® Landfill Leachate Systems

TREATMENT OF LANDFILL LEACHATE WITH REVERSE OSMOSIS AND CONTROLLED INFILTRATION OF LEACHATE RETENTATE.
In 1989, ROCHEM entered the industrial leachate (liquid toxic waste) treatment market for landfill locations, one of which was Shoemberg, the largest waste disposal site in Europe. The treatment of landfill leachate with membrane technology helps to avoid further contamination of resources such as groundwater and surface water.
Beside the ecological aspect of minimalizing the burden on the environment, the economical feasibility also has to be taken into consideration. In this regard membrane filtration has proven to be a justifiable and economic solution in most cases. This is even true when the overall costs for the treatment are compared with alternative approaches for the treatment of landfill leachate.

ROCHEM Group companies have built and installed over 70 landfill leachate plants during the last 20 years. These plants are treating over 10000 m3 of raw leachate every day.

CUSTOMISED – PLANTS FOR LEACHATE AT WASTE SITES

leachate-1
Rochem reverse osmosis plants for the treatment of landfill leachate are designed in standardized systems. The plant concepts are based on many years of broad experience in the treatment of leachate.
Various plant concepts can be supplied as the basic units for the treatment of leachate – with completely automated plant control, measuring equipment, pre-filtration, cleaning system and high pressure equipment with all the pipe work, fittings and valves ready for operation.
The basic sections are designed as the first stage for the treatment of leachate.

leachate-2
Because of the problems associated with the varying quantities and qualities of leachate, the plants’ operating parameters can be adjusted to deal with different flows.
The plant components are of optimum size, well matched to one another, and economical in operation.
The various ranges of modules provide substantial plant size flexibility during the planning and design phases. The standardized and modular designs permit accurate investment requirements and thus prevent excessive investment.

When designing the plant for landfills with large leachate yields, it is necessary to investigate whether it would be advantageous to use a design with two or three reverse osmosis plant sections connected in parallel. This allows part­-load operation and the highest possible level of reliable plant availability.

If the quality of the treated water from single stage operation does not meet the requirements, a second RO stage can be fitted downstream without the need for technical alterations. The technical designs in a second RO stage correspond to the existing Rochem Reverse osmosis standard plant range. They are available up to an untreated water capacity of 12500 l/hour.
