This job site in Central America features our small HCl Recovery System and Solids Neutralization & Filtration System. We also installed a Rinse Recovery System in the plant also (not pictured, located inside the plant).
The HCl Recovery System (on left, with yellow ladder) processes 2 metric tonnes of spent hydrochloric acid per day. The control panel (black box) contains a PLC and HMI display loaded with Beta's proprietary software program for operating and monitoring the system.
The Operation Screen is an important screen in the control panel's software program. It shows the user: the current system mode, incoming flow rate, current temperatures read by transmitters, volume of each tank, and percent output of pumps.
The second piece of our equipment at this job site is the Solids Neutralization & Filtration System.
Left photo: Solids and acid are pumped from the bottom of the pickling tank to the pH reactor (white tank). When the level is high enough, the mixer and the blower start. Lime Ca(OH)2 is added to adjust the pH for neutralization and oxidation to FeCl3.
Right photo: The neutralized solution enters the conical reactor. Sludge settles to the bottom of the conical reactor.
From the conical reactor, sludge is pumped to the filter press. The filter cake represents the only waste leaving the plant, a vast improvement over disposing tonnes of spent acid and contaminated water.
The filtrate is free of solids and is discharged.
This batch process is simple and easy to operate. The system is designed to meet pH, heavy metals, solids, and other discharge limits.
Both of these systems are shipped as modular components for assembly at your plant by a mechanical and electrical contractor or employees with those skills. Once the installation is complete, an engineer from Beta arrives to start the system and train the operators.
