Lagoons

Mapal is the best possible way to add efficient fine bubble aeration in lagoons. Lagoons can be divided into different zones: anoxic zone, aerated zone and clarifying/settling zone. The long retention time digests most of the sludge and provides very good results ( low BOD, TSS...). Mapal's aeration system has been installed in these type of plants and are successfully working for up to ten years.

Our equipment replaces high speed floating surface aerators, "splashers". These aerators have high energy consumption and suffer from maintenance problems. In order to grease the nipples of the surface aerators somone is required to enter the waste water on a monthly basis via boat.The surface aerators collect rags which create unbalanced working and eventually motor burning or jamming. Mapal provides the option to withdraw units for inspection while allowing the treatment process to continue to run as usual. The units can be relocated , added or shut down according to the conditions in the lagoon and change of the inflow rate. Diffusers life span can be up to ten years, when required the replacement can be done by replacing the membranes only, onsite.
