Local treatment facilities
Local sewage treatment plants are designed for the disposal of acid-base effluent after techno-chemical production. The use of a complex cleaning system with the use of a regeneration unit, a water treatment unit, a neutralizer allows you to return up to 90% of water for reuse.

Algorithm of work of local treatment facilities
1. The Setup-Work switch in the Work position. Press "Start", subject to the presence of sensors of the middle and lower levels in the average (B1), included K1 and H1. There is a filling tank neutralizer (B2).
2. When reaching the sensor of the upper level of the tank of the neutralizer (B2), K1 turns off, H1 continues to work, K2, A1, H2, H3 are turned on. The H2 metering pump works the time T1, which is necessary for the addition of polyacrylamide (depending on the performance for about 3-5 minutes) and is turned off by a timer.
3. Pump H1, e / m valve K2 and mixer A1 operate on a timer (running time T2 = 30min.); The pump H3 is switched on and off automatically depending on the pH of the solution in the neutralizer tank. At the end of time T2, the pump H1, the e / m valve K2, the mixer A1 and the pump dispenser H3 are turned off.
4. Upon expiration of the holding time T3 (set by the timer), the e / m valve K3 turns off, the solution from the tank of the B2 converter will start to enter the storage tank B5.
5. When the neutralizer tank (B2) reaches the level below the low level sensor, the e / m valve K3 closes and the e / m valve K1 and the pump H1 automatically turn on and the neutralizer tank (B2) starts to fill. Further, similar to PP.2 ... PP.4. If the level of the solution in the averager (B1) has reached a level below the low level sensor, the operation stops and resumes when the solution in the averager (B1) has reached an average level sensor.
6. Subject to the presence of sensors of the middle and lower levels in the storage tank (B5), the installation of the automatic protection device (A4) is activated. The dosing station (A3) turns on when power is supplied to the control panel and operates autonomously. The conductometer (A5) is switched on and off simultaneously with the installation of the automatic stand-off device.
7. After turning on the URZH.VP, the filtrate passes through the conductivity meter sensor. If the water quality is satisfactory, then the e / m valve K6 is open and the filtrate enters the collection tank (B6). If the water quality is unsatisfactory, then the e / m valve K6 is turned off, the e / m valve K5 opens and water enters the storage tank (B5).
8. If the K5 valve is in the on state for more than a certain time (for example, 5 minutes), the pump H4 and the valve K4 are turned on and the solution from the storage tank B5 enters the averaging device B1. When this URZH.VP and conductometer (A5) are disabled. The operating time of the pump H4 and e / m valve K4 is set by timer (depending on the performance of the pump H4). The condition for the emergency shutdown of the pump H4 and e / m of the valve K4 is a drop in the level in the storage tank (B5) below the low level sensor or reaching the top level sensor in the average (B1).

If the water quality is unsatisfactory, then the e / m valve K6 is turned off, the e / m valve K5 opens and water enters the storage tank (B5).
8. If the K5 valve is in the on state for more than a certain time (for example, 5 minutes), the pump H4 and the valve K4 are turned on and the solution from the storage tank B5 enters the averaging device B1. When this URZH.VP and conductometer (A5) are disabled. The operating time of the pump H4 and e / m valve K4 is set by timer (depending on the performance of the pump H4).
