CORODEX INDUSTRIES

 
 
   
  Corodex markets superior Reverse Osmosis Units designed and constructed to meet all demands for ultra pure water. Five different families of the RO Units are introduced as standard models of Corodex RO Systems with production capacities upto 400,000 GPD (1500M3/day)
 


Fine Screening
The ROTAMAT®-Fine screen can be installed in a separate container as well as directly into the channel. The waste water flows through the open front side into the basket and its screen bars into the channel. The screen bars hold the polluted material.This blinding has the effect of an additional filter. At a certain height difference the rake arm positioned on a centric middle axle is switched on. Its tines clean the basket grasping completely through the screen bars, take out the whole screenings and throw it in vertical position (12 o`clock position) into the centrically positioned trough with conveying screw. With the rotational movement of the conveying screw the screenings are transported out of the channel. For a better and complete cleaning of the tines the rake comb moves back into its upper position abt. 15°: the tines are additionally cleaned by a scraper.


Wedge Section Screening
The ROTAMAT Wedge Section Screen is installed into the channel and/or the container with an inclination of 35 ° . The waste water gets to the wedge wire drum via the open front side and flows through the wedge wire. Depending on the bar spacing, the floating, settling and suspended material can be separated. By blocking the screen area an additional screening effect can be reached which exceeds the existing bar spacing noticeably. The special shape of the wedge wire ensures that the screenings stick to the drum and reduces the danger of a clogged screen area as far as possible. The machine starts working if due to the screen area blockage a certain water level is reached in front of the plant. By means of the rotating wedge wire drum the screenings are removed. With the help of a scraper brush and a spray bar the screenings are thrown into a storage hopper which is centrically arranged in the drum. The screw conveyor in the hopper which is fixedly linked to the drum transports the screenings discharged to the closed rising pipe. By means of the integrated screenings washing in this step the soluble components are washed out of the screen and returned to the waste water stream. In this step the integrated screenings washing enables the soluble components to be washed out of the screen and to be returned to the waste water stream. The conveying screw transports, dehydrates and compacts the screenings without any odour annoyance and throws them into the provided container. The discharged screenings have a solids content of up to 40 % DR.


Micro Strainer
The ROTAMAT®- micro strainer is installed directly into the channel or into a container. The wastewater passes through the screening area. An optimum separation of floating, settleable and suspended material is assured through the inclined screening area. Rotating brushes, which are mounted on the front of the flights, clean the screening area. Solids are retained. If required (with high faeces content for instance), the screenings may be washed and soluble material separated. Then the screenings are transported into the tube where they are dewatered to approximately 40% DS, compacted and discharged into the container.
Since the screenings washing system and screenings press are integrated in one unit, you can spare two additional components in the building and reduce your disposal costs to a minimum.


Step Screen Master
The unique Step Screen principle means that solid waste particles in the fluid actually contribute to the screening process. The solid waste particles are collected on the screen's surface to form a solid layer of screenings (carpet). It is the carpet of screenings which actually carries out the screening process. In this way a screening effect is reached which is many times greater than that provided by the actual slot width. Using the screen's upward circular movements the screenings are conveyed step by step up the screen. The screenings are then fed out at the step's upper edge for further conveyance.

The success and broad acceptance of the step screen system is due to its function, the easy-to-understand operation method, the simple cleaning method without any aids (self-cleaning effect according to the counter current principle), easy servicing, its ability to handle very large screenings volumes and its operating reliability.
 
The motor linkage drive has been developed from the proven and patented link system. To the benefit of our customers, we did intentionally avoid difficult-to-maintain chain drives, with the linkage type we are able to master the occurring bending moments on the laminae, in particular with high water levels.


Step Screen Vertical
The improved development of the HYDROPRESS original:

* For big discharge heigths and deep channels
* For big througputs
The success and broad acceptance of the step screen system is due to its function, the easy-to-understand operation method, the simple cleaning method without any aids (self-cleaning effect according to the counter current principle), easy servicing, its ability to handle very large screenings volumes and its operating reliability.


Climb Max Screen
The CLIMBMAX consists of a stationary bar rack dowelled onto the channel bottom at an angle of 75°. The bar rack consists of individual flat bars that are cleaned by a rake, if necessary.

Screenings are transported upwards along the apron which comes after the bar rack. A hinged wiper pushes the screenings from the rake shelf over the discharge chute into a skip or conveyor.

These products are in great demand in African countries where waste water treatment is an integral part of the government's development plans. Corodex has been meeting this rising demand from its headquarter in Dubai. For more information on any of these products you can contact the relavant department.
