Emergency dosing tank for blue algae (Water-Link)

Purpose

Due to a shipwreck, the contents of a manure barge ended up in the Albert Canal in late 2018. The large release of ammonium was neutralised with the dosing of sodium hypochlorite.

A few months later, a strong growth of microalgae developed that was too "active". Adding sodium hypochlorite again immobilised it and allowed the filters to remove the microalgae.

Based on these two cases, Water-Link called on CGK Group's expertise to design a flexible 'emergency dosing unit' that they can use for different chemicals. Taking the necessary safety measures into account, of course.

Problem-solution

• To install the necessary systems, we used a storage container 5 m long, 2.3 m wide and 2.5 m high. The container is fully insulated, can be heated and ventilated and has a built-in spirit level.
• In the container, the necessary chemicals are mixed and distributed. Via an IBC, the chemicals are led to a main tank where 3 pipes leave for the accompanying pumps. From there, hoses can be connected to the outlets to release the chemicals into the water.
• In addition to an IBC and buffer tank, we also installed an emergency shower and eye shower with flow-through valve. This ensures that hot water is always available.
• The container also came with the necessary outrigger plates to level the container.
• The emergency dosing tank can be easily moved by truck to any location where there is too much blue algae in the water.

We are proud of this prototype in which we were able to involve all the different departments of CGK. A strong piece of craftsmanship that we produced entirely in our own workshop!
