My Current Job
As of now, I have nine years of work experience. I first started working as a part-time employee a little after entrance to the university and today it has been almost two years that I have been working as a design engineeer for Toolgostar Company. Toolgostar is a well-known Industrial equipment manufacturer and contractor company active in the field of water and wastewater treatment, having erected many PC and EPC water and wastewater treatment plants. During my stay at Toolgostar I have been privileged to work alongside many capable and experienced engineers, working on design, manufacturing and troubleshooting of various machinery.
The following is a summary of some equipment that I am personally familiar with and have worked on their basic design and optimization, detailed workshop drawings and manufacturing processes.
Vortex Grit Separator
Vortex grit separators are cost effective units for efficient grit separation. A propeller throws the solid content radially at the walls of a conical shaped basin and causes rapid sedimentation of solid content. Then the solid grit is pumped out of the basin by air lift. We recently designed the first vortex grit separator manufactured in the company for the Torbat-Heidarye wastewater treatment plant and it is currently under construction.
Reverse Osmosis Plants
As the RO desalination techniques and membranes become more cost effective, the company is looking to broaden its knowledge and expertise on the subject and take part in the RO water treatment plant projects. As a result I’m pretty familiar with RO technologies and design software such as ROSA.
Rotary or Travelling Bridges
Use of Rotary or traveling bridges on primary and secondary settling tanks and grit sedimentation units is common in the wastewater treatment industry. Therefore I acquired extensive experience on their construction, quality control and site installation.
Sluice, Penstock and stop log Gates
Gates are the most common elements used in the water industry, but our gate designs were out of date which would result in heavier and overpriced units. Together with the workshop manager I developed a better seal design that resulted in almost 10% reduction in total weight and better water tightness.
Screw Conveyor
In Torbat-Heidarye wastewater treatment plant the dewatered sludge used to stick to the belt of the belt conveyor which was supposed to transfer the dried sludge out of the building. So we proposed to replace it with a shaftless screw conveyor. The screw conveyor was then constructed according to the CEMA standards and solved the annoying problem immediately.
Overhead Crane
Actually my first assignment in the company was to design an overhead crane according to the CMAA No.74 standard and provide the workshop drawings for the dewatering building of Kashan municipal waste water treatment plant.
