AGUASIGMA products

Based on a classic activated sludge system, the use of our SIGMADAF © equipment as secondary clarifiers allows us to maximize the benefits of the activated sludge system without resorting to increasing the volume of the reactors.

The more versatile clarification water system that allows to solve many needs. The SIGMA DAF flotation systems has become the most versatile clarification system and makes the solution for a wide range of problems.

The MBR activated sludge process synthesizes all the virtues and advantages of AGUASIGMA`s aerobic wastewater treatment technologies. The introduction of membranes as a clarification element not only guarantees an extraordinary water quality in terms of solids and turbidity, but the reduction levels of COD and BOD are the highest due to the very high concentrations of biomass in the reactor, age of the very high mud and very low mass load.

Autonomous and compact plant for biological treatment with membranes. Compact and autonomous MBR system, which can both integrate hollow fibre submerged membranes as well as flat membranes.

The SBR system is a low or medium load active sludge process in which all the processes are carried out in a single tank following a sequence that corresponds to the operations that in an in-line process are carried out consecutively in several tanks. The result is an extremely SIMPLE process, very easy to adjust and highly effective for treating medium volumes of industrial wastewater that require nitrification and denitrification processes. These plants usually have a prior physical-chemical process and one or more SBR tanks. AGUASIGMA SBR systems use our dual AQJETS aeration equipment that allows the sequence of mixing in anoxia and aeration with a single mechanism.

Our anaerobic treatment system stands out for being a ROBUST solution, ideal for treating effluents with medium or high organic load that carry significant amounts of suspended solids and / or fats. Working at low volumetric loads, we achieve high COD and BOD reduction yields with a simple process, without mechanisms or internal clarifiers in the reactor, and that integrates the geomembrane cover that acts as a gasometer. The separation of the anaerobic sludge leaking from the reactor from the treated water is carried out in an external SIGMADAF © clarifier, which is equipped when a watertight cover is required to recover nitrogen gas or to collect the released biogas.

Both as a pre-treatment to eliminate easily separable particulate compounds (fats and solids in suspension), as well as constituting a complete treatment in some cases due to its extremely high reduction in pollutant load thanks to the colloidal material coagulation process. The PHYSICAL-CHEMICAL systems using our SIGMADAF equipment are one of the most effective, simple and recurring wastewater treatments for countless types of industries. Recently enhanced with SMARTDAF© technology, we have reduced the consumption of chemicals and the production of sludge, as well as solving the needs of adjusting to various working conditions.
