Zusammenfassung: | The installation (1) comprises a box (2) and a raft (3) downstream of the box with a feed pipe (30) for filling with a pump (21) provided in the box and a discharge valve (31). The box and the raft form a compact structure. The box has a first ph probe (22) to generate first ph measurement signals (sph1) and dosers (23, 24) of chemical neutralization agents for ph; the raft having a second ph probe (32) to generate second ph measurement signals (sph2) and a turbidity probe (33) to generate water turbidity (st) signals, and a fill level detector (34) ) to generate signals (sn) of the water level (n). A control block (4) generates conditioned signals (s * ph1, s * ph2, s * t) from the signals of the ph and turbidity probes, multiplexing said conditioned signals and, optionally, a signal (sb) of operation of the pump (21), and sends command signals (sc1, sc2) for the dispensers and a command signal (sc3) for the discharge valve. The block (4) additionally has processor means (413) for comparing the conditioned ph measurement signals with lower maximum ph values and higher maximum ph values (phmax1, phmax2) and with minimum minimum ph values and minimum ph values upper (phmin1, phmin2), as well as to evaluate whether the turbidity value exceeds a maximum allowed value and also to compare the fill level signal with a maximum fill level value of the pond (nmax).

La instalación (1) comprende una arqueta (2) y una balsa (3) aguas abajo de la arqueta con una tubería de alimentación (30) para llenado con una bomba (21) prevista en la arqueta y una válvula de descarga (31). La arqueta y la balsa forman una estructura compacta. La arqueta tiene una primera sonda pH (22) para generar primeras señales de medida de pH (SpH1) y dosificadores (23, 24) de agentes químicos de neutralización del pH; teniendo la balsa una segunda sonda pH (32) para generar segundas señales de medida de pH (SpH2) y una sonda de turbidez (33) para generar señales (St) de la turbidez del agua, y un detector de nivel de llenado (34) para generar señales (SN) del nivel del agua (N). Un bloque de control (4) genera señales acondicionadas (S*pH1, S*pH2, S*t) a partir de las señales de las sondas pH y de turbidez, multiplexando dichas señales acondicionadas y discrecionalmente una señal (SB) de funcionamiento de la bomba (21), y envía señales de comando (Sc1, Sc2) para los dosificadores y una señal de comando (Sc3) para la válvula de desca |
