Studies Completed

Removal of Nitrogen and Xenobiotics with MBR

  • Study of submerged membrane bioreactor (MBR) technology in the joint elimination of nitrogen and xenobiotics in waste waters using processes of partial nitrification and anaerobic oxidation of ammonium. This line of research has increased the range of technologies available for biological treatment of urban and industrial waste waters.

Pilot Plant for a treatment capacity of 1.5 m³/day made up of the following unitss;

  • Screening and feed line
  • Aerobic bioreactor
  • Anaerobic bioreactor
  • Ultra-filtration module
  • Permeate tank
  • Sludge purging
  • Sludge recirculation tank
  • Membrane cleaning system
  • Reagents dosing

UASB + UF in municipal wastewater

  • Study of processes to minimise the production of sludges, recover nutrients and optimise energy consumption in the treatment of waste waters. The aim of this project was the experimental study and completion of a technical evaluation of the different stages of a process that is conceptually different from the conventional one, geared towards minimising the amount of sludge produced and at the same time optimise the energy balance of the plant.

Nitrification-Denitrification in AnMBR effluents

  • Process for eliminating nitrogen as a post-treatment of anaerobic systems to treat urban waste waters.

MBR cleaning with Ultrasound

  • Cleaning of membranes by applying ultrasounds Novel process for MBR based on US to prevent or reduce aeration of the membrane during plant operations, reduce the recirculation flow, minimise the need for backwashing and/or chemical cleaning of same.

Reverse Osmosis Research Platform

  • Advanced tools and methodologies to optimise the design, operation and control of seawater desalination plants using reverse osmosis. Optimisation of unit processes that make up the general treatment line of an SDP using RO, analysing the influence of each stage on the following ones, and the development of advanced tools and methodologies for the design, operation and control of such installations.

Advanced pretreatments and UF in DWTP

  • Process optimisation in drinking water treatment plants with UF membranes, by applying advanced pre-treatment systems. This line enabled us to study advanced pre-treatments (hydraulic coagulation-flocculation system, consisting of multi-layer ozone treatment and filtering) before ultra-filtration membranes (UF) to improve obtained output quality and operations.

Anaerobic Treatment in the Olive Sector

  • Piloting to determine the viability of the anaerobic IC technology to treat condensates from a olives processing factory and canning of olives. For this purpose, a 60-liter up flow reactor with three-phase separator, preacidification tank, heating system and acid / base dosing and nutrients was used. The result was totally satisfactory reaching volumetric loading rates of between 15 and 20 kg COD /m³ / d and COD removal rates greater than 80%.

AnMBR treating municipal wastewater

  • Study of the application of an Anaerobic Membrane Treatment (AnMBR) in the main stream of a municipal WWTP. The objectives of this project were the determination of the viability of the AnMBR technology and its adaptation to the seasonal variations of load and temperature. Likewise, the specific production of methane, the production of sludge and the applicability of the permeate of the membranes as irrigation water were studied.

BrineRecovery

Currently, seawater desalination plants consume significant amounts of caustic (NaOH) in the desalination process. Through the BrineRecovery project, the objective is to evaluate the possibility of reducing the economic and environmental cost derived from it.

The project is aligned with the circular economy, analyzing the technical-economic feasibility of the recovery and valorization of the brine generated at the desalination plants. Focusing on products susceptible to be used in the operation of said facilities (such as, for example, sodium hydroxide and hydrochloric acid).
