Astim A.S. products

Integrated Pre-Treatment System “IPT” is compact equipment which combines all mechanical treatment process stages in One Stainless Steel Tank. While the screening and screenings treatment is done is a conveyor type screen. The grit is also settled in either non-aerated or aerated chamber which can be equipped with a grease removal chamber.

Septic sludge is delivered to treatment plants by sewage trucks. Solid content must be separated from the septic sludge before it is discharged into the treatment plant. It is necessary to clean the sludge in order to keep the load for the treatment plant as low as possible during discharge of the septic sludge. Sewage Acceptance Plant “SAP” is used for mechanical treatment of septic sludge received from sewage trucks. After mechanical treatment, the sludge is directly discharged into the digester or into the inlet channel of the treatment plant.

ASTIM - Model KAAT - Compact Waste Water Treatment Plant.

Outer Fed Rotating Drum Screens “DTI” are continuously operating screening system with automatic cleaning device. DTI is general purpose self cleaning micro screening equipment which is suitable for both municipal and industrial water, wastewater treatment plants as well as the applications for collection of recyclable materials. But it is especially suitable for separation of floating, greasy and adhesive solids. The screen is formed by a frame, a drive unit, a delivery tank, a screen drum and a doctor blade.

Mesh Belt Screens are mainly used as fine screening equipment for high capacity water intakes of power plants. There are mainly three types of installation for these equipment.

Through Flow Perforated Belt Screens are mainly used as fine screening equipment for high and medium sized municipal and industrial water, wastewater treatment plants. Especially for fine screening the perforated screening elements provide superior separation efficiency in comparison with bar screening elements. Through Flow Perforated Belt Screen is able to cope with even high amounts of gravel and grit. Also the screening elements prevent especially long fibers from passing through the screen and thus achieve the maximum separation efficiency.

CENFLO - Centre Flow Perforated Screen for separation of fine debris from municipal and industrial stream with low pressure loss trough screening equipment. Cenflo is a Centre Flow Perforated Belt Screen mainly used as fine screening equipment for high and medium sized municipal and industrial water and wastewater treatment plants. Especially for fine screening the perforated screening elements provide superior separation efficiency in comparison with bar screening elements. Also the screening elements prevent especially long fibres from passing through the screen and thus achieve the maximum separation efficiency.

Cable Operated Bar Screens HKI and TGS are robust equipment designed for heavy duty applications. They are specially designed for deep and wide channels for installation in pumping stations or inlet structures of high capacity water and wastewater treatment plants. With vertical installation possibility they require less space for screening. Cable Operated Bar Screens consist of a two main part: Parts in the channel; which are bar screen, guide frame and dead plate are equipped with parts over the channel; which are chassis, discharge chute, raking and cleaning mechanism. The upper part can be both designed as stationary (HKI) or travelling (TGS) versions.

Pin-Rack Screens (PRS) are screening equipment specially designed for installation for medium sized water and wastewater treatment plants. Suitable for both coarse and fine screening, as either a front or back raked screen, the Pin-Rack Screen ensures an efficient and reliable cleaning of the bar screen. The maintenance-free pin rack drive guarantees absolute synchronism and quiet running of the rake. The advantages of the Pin-Rack Screen are robustness and its easy maintenance due to the lack of ropes or chains for driving the rake. No moving parts are submerged in the wastewater. The steady sense of rotation of the drive motor protects the driving parts. The raking trolley can be stopped in any position thus allowing maintenance work on the operation floor without the need for a maintenance platform.

Revolving Multi-Rake Bar Screens are multi-raked chain operated screens which are generally used as coarse and fine screens for medium and large sized water and wastewater treatment plants. Revolving Multi-Rake Bar Screens are mainly consisting of bar screens, frame, dead plate and discharge chute which is equipped with multi-rakes and a counter wiper. By the help of multi-rakes very high screenings discharge capacity and low head loss is achieved. Also since the rakes are directly connected to the chain (i.e. no additional supporting structure) the installation height above level is very low even in very deep channels.
