The water supply system contains a fill valve, strainer, solenoid valve,
electrode, electrode holder, and a timing relay.
The electrode and holder are installed in one of the ports on the top of the
box. This low water safety device is designed to be in continuous contact with the
water in the control box. When the water level drops below the electrode, the
solenoid valve opens to supply the required makeup water to the system. When
the control box water level is again in contact with the electrode, the solenoid
valve closes and stops the makeup water flow. This prohibits a continuous water
overflow at the weir.
If the water level has not reached the electrode within three (3) minutes, the
timer will turn off the RotoClone exhauster and stop the RotoClone operation.
NOTE:
Since make-up water is only added to replace evaporated water losses and
sludge removal water losses, dissolved solids will build up in the scrubbing water
which can cause increased rates of corrosion. It is recommended that the reservoir
be purged occasionally and pH readings be taken once a week (with litmus paper)
and adjusted to 6.5–7.5.
This range is appropriate for most dusts except aluminum, magnesium, and
titanium, which oxidize and leave a high hydrogen ion content. A high H content
equals a low pH. This can be kept in the 6–6.5 range with an automatic (solenoid
valves on drain and makeup) purge system which lets in fresh water once each
one to four hours. For each gallon of fresh water, a gallon of low pH water is
released.
Be aware that most collected dusts are either inert or biodegradable.
However, dusts which are toxins or heavy metals may not be purged to the
sewage system. Be sure to follow the applicable regulations on this matter.
