Treatment plant with water reuse for irrigation at the National University of Trujillo, Perú

Planta de tratamiento con su reutilización para el riego en la Universidad Nacional de Trujillo, Perú

Dinotec was recently awarded a contract for the manufacture, assembly and installation of a Wastewater Treatment Plant (WWTP) at the National University of Trujillo, in Peru. The treated water will be reused to irrigate the grounds of the campus. In May, Dinotec also secured a contract for the installation of one of its modular drinking water treatment plants in Haiti and the company has also won a contract for the construction, supply, assembly and commissioning of a WWTP and a facility for the separation of oils and hydrocarbons. The latter contract forms part of a project being carried out by the ITT consortium for the Sociedad Portuaria Puerto Bahía in Cartagena de Indias, Colombia.
The experience of Andalusian water engineering company Dinotec in wastewater reuse technologies, along with its consolidated turnkey delivery system, were the main reasons behind the securing of the contract for the supply, manufacture, assembly, installation, transport and commissioning of an urban WWTP with tertiary treatment for reuse of the treated water at the National University of Trujillo (Peru).
The treatment process is designed to serve an estimated population of 3,000 and the plant will have a flow of 300m3/day. The proposed treatment system is a low-load activated sludge process with extended aeration using the exclusive Dinotec Doñana modular bioreactor. 3 Doñana units will be installed in parallel, each with an aeration capacity of 75m3. These bioreactors have a separate settling zone with a unitary surface area of 6.60 m2. The wastewater will be sent to the bioreactors by pumps.

Each unit consists of an extended aeration activated sludge reactor with a very low mass load and subsequent clarification of the water by means of a suspended sludge blanket system.

It was decided to build a covered treatment plant to prevent odours and an aeration system with a very low noise level was chosen.
