Rinsing tanks

The trapping tanks are used after tanks with toxic or valuable components. They enable to reduce the consumption of solution components subject to the use of water from the trapping tanks: for replenishment of the solution in the working tanks, for preparation and correction of the solutions in chemical and electrochemical treatment tanks.
The warm rinsing tanks are used to improve the parts rinsing quality, for example, after degreasing, chromating and chemical oxidation operations.
The hot rinsing tanks are used, for example, after degreasing and etching in alkaline solutions, before the drying operation.
The use of multistage countercurrent rinsing tanks may significantly reduce the water consumption for rinsing.

Structurally, the rinsing tanks consist of the following assemblies.
The tank body may be made of plastic or stainless steel, depending on the composition of the solution being washed and the temperature of the rinsing water.
In most instances, the rinsing tank is equipped with a drain pipe with shut-off valves.
The flow-through rinsing tanks are equipped with an overflow pocket and an overflow pipe.
The warm and hot rinsing tanks are equipped with heaters, temperature and level control sensors.
Equipping the rinsing tanks with compressed air mixing (bubbling) devices and jet rinsing (showering) devices contributes to improvement of the parts rinsing quality and reduction of water consumption.
