To round out J. Huesa’s activities, we have an after-sales department, specialized in the operation and maintenance (O&M) of water treatment facilities.

Our working maxim is to offer our customers personalized services, with the premise of improving the facility’s performance from a technical, economic, and environmental standpoint.

Cartridge and membrane autopsies (NF, MF, UF and RO)

Autopsies allow us to identify the causes of water treatment facility malfunctions and to establish the necessary corrective measures.
Depending on the irregularity detected in the facility, the autopsy can range from simple visual identification of scale or deposits (biofouling) to laboratory characterization of membranes, permeate, and plant rejection. After the autopsy we will be able to assess whether we can reuse the material (after it passes through a cleaning and disinfection system) or if it must be replaced.

“We offer personalized attention to all our customers”

Cleaning and disinfection

J. Huesa performs chemical cleaning of water treatment equipment, in order to ensure a return to operating parameters. To do this, specific protocols are followed depending on the type of fouling of the equipment.
On the other hand, J. Huesa has extensive experience in the cleaning and disinfection of water circuits, as well as tanks and cisterns, in compliance with current legislation.

Treatability studies

A good treatability test is carried out in 3 stages:

  • Sampling: it is necessary to determine the sample collection points, due to both location of currents and the variation of flow rates and loads.
  • Laboratory analysis of water/effluent to determine:
    • General parameters (pH, conductivity, turbidity, dissolved chlorine, …);
    • Cations and anions analysis;
    • Organic matter indicators (BOD, COD, …);
    • Metals and other dissolved contaminants, …etc.
  •  Laboratory tests, among which the following are highlighted:
    • Coagulation – flocculation tests (Jar – Test) to determine the type and dosage of coagulant and flocculant in order to achieve maximum clarification output and better sludge separation.
    • Bioindication.
    • Respirometry to determine biodegradability and toxicity level of water.
    • Etc.
