Eight activated carbon water treatment
systems
A major recent project for Alldos has been to plan, design build and deliver eight activated carbon treatment systems for drinking water plants around St Petersburg for Degussa
Alldos has succeeded in planning, designing, constructing and ensuring the turnkey delivery of eight containerised systems for processing 10% activated carbon solution for drinking water treatment, in an absolute minimum of time Shortly before Christmas 2005, a huge inquiry from Russia landed on the desks of our project engineers

New from Alldos, the Primus 208 Plus 3 system dosing pump is designed for use with gassing chemicals such as sodium hypochlorite
The company - Degussa Moscow, a satisfied Alldos customer of many years standing - asked for support, and urgently.
Eight waterworks around St Petersburg required help in treating drinking water using activated carbon.
Despite the upcoming public holidays, the team of experts from Alldos got straight to work drafting plans and cost estimates and checking dates with suppliers.

Their rapid reaction paid off just as quickly.
The company quotation was successful and the contract arrived in the third week of January.
The task now was to design, construct and arrange the turnkey delivery of eight container systems for processing the 10% activated carbon solution in the shortest time possible.
Just eight weeks from the date the order was received, the first two stations left the plant headed for Russia and the last two containers were on their way before the end of June.
At the heart of each container station is a dosing system with a mixing tank for activated carbon.
The largest system has a tank volume of 7,000L and the dosing rate can be set at up to 9 x 1200L/h.
A particular highlight in all eight systems is the PLC panel with ultra-modern, high-resolution touchscreen panel.
It depicts the entire activated carbon processing unit as a flowchart on site.
Individual components, such as the eccentric screw pumps integrated into the container station, can be selected at the tap of a fingertip.
Employees at the waterworks can then use plain-text submenus in Russian to carry out all adjustments quickly and easily.
Additionally, all input and operational data, measurement values and reports are saved in a log book and can be called up onscreen without the need for a keyboard.
Five of the container stations are also equipped with a silo and a big-bag emptying station for pneumatic transport of activated carbon.
The sizes of the silos vary - in two stations capacity is 70 m3, two of the systems offer 15 m3 and one has a silo with a capacity of 10 m3.
Straight after one project another one starts - work is already well underway on yet another major contract from Iran for two drinking water treatment systems to be housed in watertight sea transport containers. Request a free brochure from Grundfos Alldos ...
